Ranunculus are cool season flowers that grow best in spring-like temperatures of about 55°F. In warm climates (zones 8-10), the corms are planted in the fall so they bloom in late winter or early spring. Plant ranunculus in beds and borders, cutting gardens and containers. Planting of ranunculus at home. If you want to grow ranunculus on the balcony, care for it is no more difficult than in the garden, and, nevertheless, in order to successfully grow ranunculus at home, follow the advice of experienced gardeners. It is better to plant home ranunkulus in a group and not to grow it as a single plant. Typically, for fall planted tubers, roots and sprouts grow in the fall, taller growth appears over the mild winter, and flowers come in the spring. Fall planted tubers bloom in early spring and continue steadily for six to seven weeks. Late winter planted tubers will flower by mid-spring and continue for four to six weeks. If you enjoy container-gardening, include some ranunculus tubers (Ranunculus spp.) in your pots, either by themselves or mixed with other plants.

Ranunculus (lat. Ranunculus), or buttercup, is a plant of family Ranunculaceae native to Asia Minor. Its name was given by an ancient scholar Pliny meaning 'a frog' in Latin since many species of buttercup prefer marshland as all amphibians do. Ranunculus was brought to England from Turkey in the 16th century and soon it became a favorite flower of gardeners, but by the end of the 19th century its popularity had somewhat decreased and it was revived only in the current century.
Today there are more than 600 species of ranunculus. Ranunculus flower can stay fresh in a vase with water up to two weeks. In Italy buttercup is called 'golden buttons of meadows.' A beautiful legend has it that buttercups are small stars that were turned to the flowers by Jesus and presented to his mother as a sign of respect and love...

Ranunculus flowers

Buttercup

is a very beautiful flower. It is grown in the garden and in the pots at home decorating terraces, balconies and living rooms. The plant reaches a height of 8-32 inches. It has deeply lobed leaves and strong stems. Rhizomes are tubers looking like goose feet. Stocky rhizome, leaves and stems of ranunculus look like the leaves, stems and roots of dahlia. Lovely double, semi-double and heavy double inflorescences of different colors, except blue and light blue, reach 2-4 inches in diameter and in turn bloom from May to August. When they begin to open, they look like roses, and when they are fully opened, they look like double poppies. White ranunculus and pink ranunculus are very popular among brides and they are often used in wedding bouquets. However, you should keep in mind that ranunculus juice is poisonous.

In a culture species and varieties of ranunculus asiaticus are grown. Initially it has two varieties: Persian buttercup (Ranunculus Persian), the blossoms of which look like a rose, and turban buttercup (Ranunculus africanus) that resembles peony blossoms.

Peculiarities of ranunculus growing

• in order not to burn the roots while feeding ranunculus, apply only those fertilizers that include vermicompost;
• the plant does not like transplanting, so it is better not to worry ranunculus without extreme need;
• during flowering ranunculus needs potassium and limestone;
• during flowering, place the pot with a plant in shade and reduce watering for ranunculus to bloom longer;
• ranunculus is not cold hardy, so it is necessary to dig the tubers out of the ground before frosts as soon as its leaves wither away;
• you can plant buttercups of different colors in one pot and you get a beautiful and elegant bouquet;
• it is better to remove faded inflorescences for the new ones to start blooming faster, and in late summer the stem should be cut up to the ground.

How to grow ranunculus in the garden

Preparation of soil for planting

Buttercup can tolerate direct sunlight, but still it prefers partial shade in which the color of its inflorescence becomes brighter and it blooms longer. It should be protected from drafts. Before planting, you should be sure that there will be no frosts any more. Ranunculus prefers a neutral, light and fertile soil, for instance, black soil with sand and humus, or peat neutralized with chalk. You should avoid using of loamy soil. The main thing is that soil should absorb water without moisture stagnation in the soil. It is necessary to arrange a good drainage, otherwise your flowers may rot. This can be done, for example, by adding a little of sand into the planting hole. Before planting of ranunculus, dig the soil over, add compost into it and treat it with fungicide.

When to sow ranunculus seeds

It is not easy to grow ranunculus from seeds, therefore, do not count on this method: ranunculus seeds have a very low germination. But if you want to know how to grow ranunculus from seeds, we are ready to share our experience and knowledge with you. It is better to take ranunculus seeds from the first blooming buds by wrapping them with gauze after they faded for the seeds not to fall on the ground. In mid-February sow them in a light fertile soil and cover with soil layer 0.6-0.8 inch thick. Cover the container with glass or foil and keep it in a well-lit place with a temperature of 59-63 ºF. From time to time moisten the soil. After two or three weeks, when there are shoots, remove the cover, and when the seedlings get two pairs of leaves, they are pricked out into separate pots, and when there is a warm weather, they are planted in the ground. They will bloom only in the next year, so ranunculus growing from seeds is not suitable for flower growers that count on quick results.

When to plant ranunculus tubers

When the soil gets warmed and there is no risk of spring frost (around the end of April or early May), it is time to plant bulbs of ranunculus. Planting of ranunculus flower is a simple and easy process, but there are some important points that should not be missed. To get ranunculus tubers prepared for planting, they are placed in a moist condition (sponge, wet sawdust or moss) for several hours. You can simply soak them in a cold water or in a weak solution of potassium permanganate. Sometimes growth stimulant can be added into water. Since the plant does not tolerate transplanting, you should think well how to plant ranunculus correctly at once, that is, what site will be really comfortable for the plant. How to plant ranunculus? Ranunculus tubers are placed in the hole at a depth of 2-3 inches. The distance between tubers should be 4-6 inches. If there is a chance of a sharp temperature drop, cover the flower bed with a frost protection fabric or straw. In two-three months, there will be several stems growing from each tuber, and later the first flowers of ranunculus will bloom.

Ranunculus: care in the garden

Care for ranunkulus is quite simple. Ranunculus needs a regular but moderate watering, so that excessive humidity will not cause the roots rot. The first signs of decay are mold on the leaves and buds dropping. Remove the damaged parts of the plant, loosen the soil around them, reduce watering. Faded inflorescences should be removed timely, so they do not hamper a new bloom. Ranunculus needs loosening of the soil and feeding with organic fertilizers: every two weeks apply potash fertilizers (1.5-1.8 oz per 11 ft² of soil) during the flowering period (potassium chloride, potassium sulphate or wood ash). Sometimes, especially in the dry summer, ranunculus can be attacked by a spider mite. The stems and leaves of plants attract aphids and thrips, and if you notice silver or white spots on the leaves, you should immediately treat ranunculus with insecticides. As a preventative measure, it is recommended to spray ranunculus with an insecticide 2-3 times a week.

Ranunculus at home

Planting of ranunculus at home

If you want to grow ranunculus on the balcony, care for it is no more difficult than in the garden, and, nevertheless, in order to successfully grow ranunculus at home, follow the advice of experienced gardeners. It is better to plant home ranunkulus in a group and not to grow it as a single plant. Prepare or buy a decorative box or a large, wide pot with drainage holes and plant ranunculus in it. For planting you should use the same peat-based substrate as in the garden. The day before planting, soak the tubers in the water. At the bottom of the box or pot, put the drainage layer (gravel, expanded clay, egg shells), then put a layer of the substrate, place the tubers of ranunculus, add some more substrate so that you could see only the top of the bulb. If the pot is wide enough, plant a few tubers. Water ranunculus in the pot and for the first time keep it at the temperature not exceeding 54 ºF, from time to time moisten the soil.

Care for ranunculus at home

When the seedlings reach a few inches, temperature may be slightly increased (up to 68-72 ºF), during flowering period it should not be below 64 ºF, but not higher, because then ranunculus at home will bloom too shortly. The most important point while caring for ranunculus at home is to avoid a direct sunlight. It feels great on the eastern and western windowsills, but if you can, place it on the south windowsill, and it will reward you with a spectacular flowering. After the onset of warm days the pot or box can be taken out to the balcony or terrace. Watering of the plant should be regular with fertilizers added to water during the growing season. Top watering is preferred, but try not overwet the soil. Sometimes the plants are sprayed with water. After withering of ranunculus watering should be reduced.

Ranunculus after flowering

Digging out and storing of ranunculus

Autumn has come. It's time to dig ranunculus out. Growing of this plant should not be time-consuming. And this concerns the last step. Once ranunculus leaves turn yellow and wither, stems and leaves are cut off and tubers of plants are removed from the ground. This should be done very carefully, since the ranunculus roots are very fragile and any careless movement can break them. Actually ranunculus is a perennial plant, but it cannot stand the temperature below -19 ºF, so it is better to overwinter in a well ventilated basement at 39-43 ºF, wrapped in dry moss or paper bag. Before placing it for winter storage, you need to process ranunculus with fungicides for 30 minutes and dry it well in the shade for three days. If your ranunkulus is perennial and there are no harsh winters in your area, leave the rhizome in the ground, just cover it with spruce branches or fallen leaves. Even if some of the tubers die, you can always buy more plants to plant in the spring.

Ranunculus at home after flowering

You can save the plant after flowering by placing it in a cool, shaded place, where ranunculus has some more time to grow. Then a dormant period comes that is preceded by the yellowing and drying of leaves and stems. Place ranunculus into the room with the temperature of 59-64 °F after transplanting it into a new soil. The dormant period lasts no more than a month, and in April you will see new shoots. Each tuber during the growing season gives 5-7 new shoots. When digging them out, they are carefully separated and planted or stored in the basement or in the refrigerator on the shelf with vegetables until spring. But it is necessary to know what ranunculus grown from stored tubers will be weaker and the flowers will be smaller. That is why many growers prefer to buy new tubers every year.

Important information about growing Ranunculus

• Thrives in zones 8 to 11 but can still be grown with much success in colder climates like zone 7 or lower if treated as an annual.
• Blooms between early spring and summer but this is dependent on the climate on which it is grown.

Varieties of Ranunculus

As mentioned, there are more than 500 species of ranunculus. Some of the most common are:

• Buttercup – the most common and most recognizable representative of the ranunculus genus. The buttercup is characterized by crepe petals. The flowers can come in all sorts of colors. Some horticulturists have managed to create designer patterns and shades for it.
• Ranunculus asiaticus – The flower it produces are multi-colored and feature tubers with gnarled claws.
• Ranunculus ficaria – Commonly appears in North America’s wilds. You can find them in areas like woodlands, alongside streams, and meadows.
• Ranunculus hanoi – The flowers are colored a light shade of pink with the shape that is reminiscent of a rosebud.
• Ranunculus tango – the flowers have been compared to how roses look.
• Ranunculus acontifolius – Most ranunculus thrive in dry conditions with lots of sun. But the ranunculus acontifolius is different in that it prefers conditions that is opposite – moist with dappled shade. This species is grown best during spring and would usually lie dormant when the summer season arrives.
• Purple picotee – The flowers possess petals that are lilac white and crimped edges colored purple. These prefer more moisture and good drainage.
• Amandine rose – A subspecies of the aforementioned asiaticus. The Amandine Rose is one of Holland’s most popular exports mainly because its flowers are so beautiful – what with its ruffled petals that appear in layers. The flowers are bright pink.
• Ranunculus venere – The flowers come in an uncommon color that can be best described as halfway between pink and coral.
• Ranunculus lyallii – This flower is originally found in New Zealand. This is one of the tallest species, able to grow up to three feet in height. The flowers are described as having a yellow center and surrounded by white petals. It thrives in soil that rocky and loves a lot of sunlight.
• Cloni dark orange – This species’ bulbs are propagated very strictly in labs in Italy. The flowers are shaped similarly to the English Rose. The petals have a bright orange color.
• Rhone pink – This is a designer species developed by the Japanese. The flowers are characterized by layered pink petals, akin to a rose.
• Snow buttercup – this flower, with the species name of ranunculus nivalis, is found in the arctics and Alaska. This is a small flower that would almost look like it suddenly blooms in the summer when the snow melts. These pretty flowers have gold petals and a green center.
• Ranunculus alpestris – This species is another one that thrives in cold weather. It has small, white flowers.
• Ranunculus cortusifolius – A species endemic in the Canary Islands. This species has small white flowers and blooms around spring.
• Ranunculus acris – known among the horticulture community as the easiest to grow among the different ranunculus varieties. It often grows in boggy areas but is hardy enough that it will thrive in almost all types of soil.

Planting Ranunculus

There are certain things you need to consider first before you begin planting ranunculus.

It’s important to choose a good quality plant

Ranunculus begin as corms – which look like small octopus or tiny claws. Remember that the larger the size of the corm, the bigger the stored food inside – which means that the plants that come out of these corms will be stronger and hardier. It will also produe more flowers.

Choose the right spot in your garden

Choose a good location for your ranunculus garden patch. Remember that most species have a preference for cool weather and grow the most on a place that has full sun exposure to dappled shade (for other species).

Take a look at your drainage

Make sure that the beds you use for planting have adequate soil drainage. A good gauge of drainage capabilities is to check the area after it rains. If you see that water is still puddling about 5 to 6 hours after it rained, then you should look for another location.

A solution to drainage problems if you have limited space is to add an additional two to three inches of an organic material, which will help in draining water. These organic matter can be something like compost, ground bark, decomposed manure or moss.

Consider container planting

One way to eliminate the issue of drainage is to use a container for planting your ranunculus. Choose the right size container that will fit the amount of bulbs you wish to plant and make sure the container has enough holes in the bottom for water to exit.

Fill your container with a high quality potting mix that provides adequate nutrients and also allows water to drain completely to prevent rot.

The advantage of container planting is that you can move it to an area that will get the right amount of sunlight – something you can’t do if you plant on a flower bed. Container planting is also advantageous if you live in very cold climate because you can move the plants if the weather outdoors get too cold.

Pick the right time to plant

Finally, make sure that you’re timing your planting in the right season/climate. Ideally, you should begin planting the bulbs around fall. If you plant outdoors, you don’t need to worry about protection from the weather if your area’s temperatures don’t drop below 10 degrees Fahrenheit.

But if you live in a place where temperatures can drop below freezing for long periods of time then it will be best to wait to begin planting around the tail end of winter or even when spring starts. Another option would be to plant them indoors first. You can use a pot for this and time it so that it is about 12 weeks before any frost was recorded.

When the plant begins to sprout it will be hardy enough to withstand light frost. Expect your plants to begin flowering approximately 90 days after you’ve planted them. If the temperature dips enough that frost happens you can protect your plants by covering them with a frost cloth.

Don’t forget to prepare the growing bed for your ranunculus. Use a good amount of compost and balanced organic fertilizer and mix it completely in the soil.

Tips when using different starters

Since you can ranunculus using different types of starters, here are tips you should remember for each type:

Tubers or Corms

Before you plant the corms, you need to prepare them first. Soak them in room temperature water for about a few hours, about 4 will do.

A good tip is to leave the water running for a time as it provides them with a little more oxygen in the water. While it is soaking, the corms will begin to swell, usually up to twice its original size. After the pre-soak is done you are ready to start planting.

Remember to plant it with the claws/spines pointing down. Provide even spacing for each corm of about 6 to 8 inches and then cover it with about an inch deep of soil.

Alternatively you can just bore a small hole about two to three inches in depth and drop the bulb inside (remember, claws down for the bulb) and then cover the hole. Just remember not to tightly pack in the soil. A gentle pat to put the soil in place will be more than enough.

You need adequate space in between the corms because the plants develop a large root ball. After this, water the soil completely.

One other method you can use after pre-soaking the corms is to allow it to pre-sprout. Many enthusiasts prefer this method because presprouted corms will be slightly stronger and will also mean that it flowers a few weeks earlier compared to corms that were not presprouted.

To pre-sprout, get a flat-bottom seed try and fill it with some pre-moistened potting soil. Sprinkle the pre-soaked coarms and then cover it with soil. Put the tray in a cool area (making sure that it is rodent-free) and leave it for up to two weeks.

Do check in on the tray every couple of days to ensure that the soil is moist but not wet. Remove any corms that have rotted or have mold.

The corms will grow to twice its size and will begin sprouting little roots. When the roots are approximately an eighth to half an inch in length you can now plant them on the ground.

Seeds

When using seeds, sow them indoors around the last weeks of winter in a bed that consists of seed starting mix. These seeds will develop the most in a mix that also has peat. The idea here is to germinate the seeds and they will be more likely to do this in temperatures that hover between 50 to 60 degrees Fahrenheit.

When the seedlings begin to peek out of the mix provide some moisture and making sure that they are not in direct sunlight until you’ve already planted them outside. Ranunculus grown from seeds will usually flower in about 3 to 4 months after you’ve planted them.

Regardless of the starter you used, remember to avoid watering the seedlings until after leaves have started to sprout. The leaves usually appear around springtime but of course will vary depending on when you began planting and where you planted them.

Caring for ranunculus

While ranunculus are relatively hard plants you should still remember to follow these tips to ensure that they will grow success.

Make sure that your ranunculus is always kept moist. Water them regularly but make sure that I’s not completely wet. Just provide enough moisture to keep the soil damp.

Remember that too much water (overwatering them) and subpar drainage of water can result in your bulbs/corms/seeds rotting. A good rule of thumb is to only water your ranunculus when its hot and dry for an extended period of time.

Fertilizer is minimally needed if you are planning to grow your ranunculus as an annual. But if not, a good organic fertilizer added to the soil every few weeks will give your plants adequate nutrients.

One of the problems associated with growing ranunculus plants are various pests or plant diseases. Some of the most common problems associated with this plant are mollusks, aphids, and fungi. But these are relatively normal problems that can be remedied quickly.

You can just go to a garden supply store and look for the appropriate fixes for these problems. You can also use homegrown solutions to these problems.

For example, to remove aphids from your ranunculus plants, you can prepare a water and liquid soap mixture and then spraying the solution on to the infected parts of the plants. The mixture actually dissolves the protective outer layer of these pests, which then kills them.

The good thing about this solution is that it’s not only natural, it won’t hurt your plants or even other animals or insects that are considered friends to your plants like ladybugs, bees or lacewings.

Ranunculus after blooming

Growing Ranunculus In Pots

Once your ranunculus have started blooming, sit back and enjoy the fruits of all of your hard work. You can now begin preparing and getting those lovely flowers in your home’s flower arrangements.

You can cut the stems when the buds have colored and it feels like a marshmallow when you lightly squeeze it. Cut them when they are not yet fully open. The reason for this is that if you cut the flowers when they are fully bloomed, they will still last a few weeks but the flowers are going to be more delicate and fragile.

Remember to “deadhead” the plants when needed. Remove all the dead flower heads from your ranunculus plants to keep their appearance neat and to also encourage them to flower.

You should also remember to always remove or trim excess foliage to keep them looking neat and tidy. When the plants are beginning to yellow and die, stop watering them as they won’t need the water anymore. This is the sign that the blooming season has ended.

The bulbs of the ranunculus are relatively affordable so many gardeners consider planting them as annuals. If you’re going to do the same, you can compost the plants after they bloom and the foliage has died.

If you want to save some money, you can save the tubers and replant them next winter or spring. Just dig the tubers out, remove any dead matter and foliage, dry them completely and then store them in a cool, dry place. This way you won’t need to buy new tubers next planting season, unless you want to try other varieties and colors.

You should also remember to collect the seeds from the flowers as an additional resource for planting for the next planting season. When the petals of the flower have fallen off, the seed head will mature and then dry out.

You can harvest the seeds by either shaking the pod or rubbing it between your palms. The seeds can also be used a great gift to your fellow ranunculus enthusiasts. They’ll surely appreciate seeds.

Tried and tested tips from gardeners

Gardening and flower forums are full of practical tips from fellow gardeners and enthusiasts who have great success in making their ranunculus flower patches thrive.

1. Invest in good potting soil

To ensure that your plants grow healthy, you should fortify the soil with a good potting mix to ensure they get the nutrients they need.

Ranunculus Grow In Pots

2. Plan out your landscaping

While it is tempting to get different colors of ranunculus and growing them at the same time, hobbyists actually recommend that you should just get one color. and then pair it with other complimentary blooming spring plants. It will make for a more visually appealing garden with unique color combinations.

You can try:

• pansies
• primroses
• violas
• oriental poppies
• daffodils
• peonies
• snapdragons

3. Let sprouts grow undisturbed

If you plant during fall then leave them alone. In areas that are warmer than what these plants prefer, they will actually form these small roots and sprouts that hate being disturbed.

4. How to prolong a ranculus bouquet’s beauty

When your cut flowers have started to sag, you can still prolong their beauty by removing the lower leaves and cutting the stems so they’ll stand up straighter. Do remember to change the water every other day.

The stems of the ranunculus are hollow and quite fragile, and actually easily rots. When in a vase, keep the water level low.

A great way to display ranunculus is to put it in a round vase with the leaves removed. This creates a compact, round bouquet.

Another great way to display ranunculus flowers is to place them in fruit cans and place colorful labels that will either complement or contrast with the ranunculus’ colors.
