How to Grow Ranunculus | Garden Gate

Ranunculus are cool-weather beauties

I’ve always admired ranunculus (also called Persian buttercup) — those beautiful flowers are real attention-getters in photos and florist’s bouquets. One spring I bought a bag of ranunculus tubers on sale at a big box store in late spring. Unfortunately, when I tried to grow them, the results weren’t great — spindly foliage and no blooms. I just chalked it up to them being difficult to grow. Then I learned they’re really cool-season flowers and thrive in the same conditions as pansies (Viola spp. & hybrids), snapdragons (Antirrhinum majus) and other spring favorites. Let me introduce you ranunculus and some of the things I’ve learned since my first disappointing effort.

How to use ranunculus in the garden

It’s easy to work in ranunculus near the front of a border. See how 12- to 16-inch-tall Bloomingdale II Orange in the photo above fills the gap between lower-growing primrose (Primula hybrids) and spiky snapdragons behind? While ranunculus look great planted in mass like this, you don’t have to buy buckets full of tubers to enjoy these pretty plants. Because each ranunculus can have several 2- to 5-inch flowers open at one time, smaller-scale plantings are just as pleasing. In areas where they’re cold-hardy, position ranunculus near perennials or shrubs to hide the foliage as it fades and the bare spot dormant plants leave behind.

Use ranunculus in early spring planters

Ranunculus puts on quite a show — perfect for early spring containers like the one above. Flowering can continue up to five weeks, with individual blooms lingering for three to seven days in cool weather. If your soil is poorly drained, a container like this one gives the tubers just what they need to grow beautiful plants.

How to buy ranunculus tubers

You’ll find the best selection of tubers in late fall, though there are usually some available in early spring, too. When you buy them early, store the bag in a cool, dry place that stays 50 to 55 degrees F until it’s planting time.

Where to buy ranunculus tubers

How to grow ranunculus

Grow ranunculus in full sun to part shade in moist, well-drained soil. Ranunculus are cold-hardy in USDA zones 8 to 11, grow them as annuals in colder zones.

Lots of light

With full sun, lots of organic matter and well-drained soil, ranunculus will look great and produce plenty of flowers.

Watch the water

Poor drainage causes plants to rot. Keep them moist, but not wet, while the foliage is green and flowers are blooming. But they’re more likely to keep coming back if you let them dry out as they go dormant. A bimonthly application of a liquid plant food, such as 12-4-8, will produce more flowers.

Trim to keep tidy

Deadheading helps to keep ranunculus blooming. Cut the stems back below the foliage to tidy plants.

As temperatures regularly get above 70 degrees F during the day, ranunculus slows its flowering and gets leggy. If you’re growing it as an annual, that’s a good time to pull plants out. Otherwise leave the foliage in place so the tubers can store energy for the following year. The leaves will eventually yellow; then it’s OK to cut them off at soil level.

How to start ranunculus tubers

In USDA zones 8 to 11 you can plant ranunculus tubers in the ground in fall — the foliage often sprouts and stays evergreen until plants bloom in late winter. In colder zones you will want to start the tubers inside.

Planting ranunculus tubers inside

Where ranunculus isn’t cold-hardy (zone 7 and colder), start it indoors. Plants grow best when daytime temperatures are in the mid- to high 50-degree F range and take 12 to 16 weeks from planting to bloom. So check your records or check online to see when these temperatures usually occur for your area and count back from there to start ranunculus tubers. This means you may need to plant them inside as early as January.


Soak ranunculus tubers before planting

I’d read about starting ranunculus tubers and saw lots of debate about whether to soak them first or not. So I talked with Ken Harr, product technical manager with Sakata® Seed, who grows lots of Persian buttercups. He said that both approaches work but the important thing about soaking is to not forget them. You can leave them in water for as little as an hour or as long as overnight, but no longer. Otherwise they get water-logged and may rot. The key with unsoaked tubers is keeping the potting mix moist but not soggy until you see growth. After that you can allow the mix to dry out between drinks.

Planting ranunculus tubers

How to store ranunculus tubers

Where ranunculus isn’t hardy, most gardeners grow them as annuals. But you can keep your favorites to grow again by digging tubers after most of the foliage has died back in early summer.

Ranunculus varieties to try

There’s not a big size range among ranunculus; they'll grow 8 to 18 in. tall and 6 to 12 in. wide. The ranunculus you find at your local garden center are often sold as a mix, but you can get them in red, pink, orange, yellow, purple, white and bicolors. If you want a single color, your best bet is a mail-order nursery.

In addition to the varieties you will see below, you’ll also find the petite Magic™ series. It grows 8 to 10 inches tall and wide and makes a colorful edging for a path or patio. Tecolote® is one of the tallest, at 12 to 18 inches tall and 8 to 10 inches wide. Its long stems make it great for bouquets.

Ranunculus flowers come as singles and doubles, some of which are densely packed with petals. Also known as the Persian Buttercup, and referred to by some gardeners as 'the rose of the spring’, these flowers, unlike their yellow wildflower relatives, are available in a spectrum of shades from yellows and oranges through to pinks and purples and are perfect flower bed ideas for giving you that romantic rose fix in spring.

Ranunculus are perfect for bringing spring color to borders or containers, but are also brilliant for cutting, boasting an outstanding vase life, plus, they are not readily available in supermarkets or from many florists, so are perfect for growing yourself.

Once cut and striped of their leaves, they will last at least a week or more in clean water. To get the most out of your ranunculus, cut them when the buds begin to show color and are still soft.

How to grow ranunculus

Ranunculus will thrive in a sunny, sheltered spot with free-draining soil and should be protected from strong winds. If placed in a waterlogged or boggy position the tubers may rot.

Ranunculus are half hardy, so it is recommended to start them off in pots under cover and to transplant them once the risk of frost has passed. They can be planted directly into the ground in warmer areas, but it is recommended to cover them with a cloche or fleece on cold nights. 

See below for instructions on how to grow ranunculus.

Growing ranunculus in pots

Ranunculus grow well in pots so are a container gardening ideas for bringing spring color and interest to a patio area, small garden or balcony. Being half hardy, it is best to start ranunculus off in pots undercover, and overwintering them in a greenhouse. 

Choose a large pot and place crocs or gravel at the bottom to aid drainage. In autumn, part fill the pot with compost and plant several corns 2in apart around 4in deep, ensuring the claws are facing down. 

Keep undercover in a greenhouse or conservatory over winter. Once the weather warms in spring, the pot can be moved outdoors into its desired position. In autumn the pot can then be easily taken back under cover to be protected from frost until the following spring.

When to plant ranunculus

Ranunculus are versatile and can be planted in September – November for spring flowering, or in spring for flowers in summer. Planting ranunculus in autumn will bring blooms in early spring - the perfect way to banish those winter blues.

How do you take care of ranunculus?

Ranunculus will need watering in dry weather and during flowering can be fed with a high potash fertiliser.

Once ranunculus have flowered, let the foliage die back naturally to help nourish the corns, then in autumn cut them back.

How to grow ranunculus in a pot at home

The first association that arises when mentioning a ranunculus plant in a pot is sunshine and freshness of greenery, which give a special spring mood.

That is why this culture is popular among flower growers. And florists often use potted buttercups to decorate living spaces and ceremonial halls.

How ranunculus looks and reproduces

Ranunculus is a perennial herb of the ranunculus family. Asia Minor is considered its homeland. The flower has several simpler names: Asian buttercup, Adonis, fierce color.

Lat. Ranunculus

Buttercup cultivation has been known since the 16th century. This culture was spread almost all over the world. It was cultivated in Asia, in Europe and Northeast Africa. Therefore, ranunculus has many additional definitions. nine0003

This flower was also known in antiquity, which is confirmed by the numerous references to buttercup in myths and legends. Recently, the popularity of buttercups has been increasing.

They are increasingly being used not only as decorative ornaments, but also in the preparation of flower bouquets and compositions.

Translated from Latin, ranunculus means "frog". The flower received this name because under natural conditions it grows near a reservoir or directly in them. nine0003

In nature, there are more than 500 species, but only low-growing hybrids are grown at home. They have large flowers and a wide leaf plate.

Lush and long flowering. Rosettes on the bush bloom continuously for 1-2 months. Usually in June-July.

Propagation of ornamental ranunculus varieties is carried out in two ways:

To germinate seeds, you must first soak them in water for 2 hours. Then they are planted in the prepared soil substrate to a depth of 3-4 cm.

Glass or oilcloth creates a greenhouse effect in a flowerpot. Periodically, the soil is moistened with a spray bottle. After the appearance of sprouts, the pot opens.

Transplantation and diving of seedlings is carried out after the appearance of 5-6 leaves. This method is long and laborious and often does not bring the expected result.

Ranunculus is more efficiently propagated by bulbs. The plant annually produces an increase of 5-7 young sprouts. They are separated and transplanted into a new container. The plant takes root well and blooms quickly. But often there is a grinding of the color rosette. nine0003

Experienced flower growers recommend purchasing new planting material from nurseries every year. Such plants develop much better, their flowering comes earlier.

Owners of ranunculus, regardless of its type, must take into account the fact that the juice of the plant is poisonous. Therefore, when caring for it, you should wear protective gloves, and also put the flowerpot in a place inaccessible to children and pets.

How to grow ranunculus in a flower bed

Tubers are planted in open ground in mid-April. The top layer of soil should warm up by 5-8 degrees. Before planting the bulbs, preliminary preparation is carried out not only of the soil, but also of planting material. nine0003

Beautiful ranunculus plant

The soil in the planting hole should be light and loose. To do this, it is mixed with river sand and peat.

You can enrich the soil with nutrients with the help of rotted manure. Do not add fresh organic matter to the hole, as this will lead to the death of the tuber.

10-12 hours before planting, bulbs should be placed in clean water. 1-2 hours before planting, a root formation stimulator is added to the vessel.

How to properly plant ranunculus in open ground:

For greater decorative appeal, florists recommend planting buttercups in small groups. This can be a single bush or trench landing.

To add brightness and contrast, flower growers often plant several types of plants with different sizes and shades of flowers in one flower bed. nine0003

Not only high-quality planting material and proper planting, but also proper care of ranunculus allows you to get a bright living carpet with lush greenery. After planting the tubers in the open ground, the flower should be regularly:

Rununculus does not like transplants. Therefore, when forming a flower bed, you should find a slightly shaded place for it on the south side. nine0003

If you plan to constantly change the location of the flower bed, it is better to grow a flower in a pot and, if necessary, simply rearrange it.

Potted buttercups grow well and bloom indoors. Therefore, this method of growing also allows you to decorate your home or workplace with bright colors.

Growing ranunculus at home in a pot - planting and care

A flower in a pot, for example, a ranunculus in a pot, can be used as an interior decoration, or decorate balconies and loggias with it. Ranunculus at home in a pot develops no worse than when it is grown in open ground. nine0003

At home, varieties with short stems and multiple large leaves are planted. The cultivation of hanging species is also possible. Regardless of the option chosen, for planting you need:

Colorful flowering of bright ranunculus

You can buy quality planting material only in specialized stores. In such points of sale, the bulbs are stored under appropriate conditions. This allows them to maintain their viability. You should not buy bulbs at fairs or in the market. nine0003

It is important to carefully inspect them when buying. Tubers should be dense, their surface without mechanical damage and traces of pest damage. It is also unacceptable to have mold, dried or rotted areas.

At home, flower growers recommend planting a plant in a group, not singly. Therefore, when choosing a flowerpot, preference should be given to wide oblong pots or decorative boxes. The material of their manufacture is selected depending on the purpose of cultivation. nine0003

A pot made of ceramic or glass with a wide drainage hole is suitable for decorating the room. Its diameter is at least 15-20 cm. If it is necessary to germinate the bulb before planting in open ground, it is permissible to use plastic containers.

The soil for the flower must be loose. Ready-made mixtures based on peat are suitable. Broken shards of ceramic flowerpots can be used as drainage. Expanded clay or eggshell.

Planting a ranunculus in a pot is carried out in the following way:

Growing a flower on the windowsill

Next, the pot is placed on the windowsill on the south side. Caring for ranunculus at home comes down to maintaining the average soil moisture and observing the temperature regime within 18 degrees. nine0003

The tubers should germinate within a few weeks. When the sprouts rise a few centimeters, the temperature in the room must be raised to 22 degrees.

During the vegetative period, the flower is regularly fed with special fertilizers. Watering is carried out three times a week, the soil should be constantly slightly moist. Watering is reduced after the plant wilts.

The dormant period of ranunculus grown in a pot lasts within 1-1.5 months. Preparation for it consists in transplanting tubers into a fresh land substrate. Then the pot will be placed in a shaded place with a temperature of 15-18 degrees. nine0003

Timeliness and proper care significantly affect the development and visual appeal of the flower. Therefore, compliance with the recommendations of flower growers is mandatory.

Expert opinion

Yuliya Yuryevna

I have a large garden and vegetable garden, several greenhouses. I love modern methods of plant cultivation and soil mulching, and I share my experience.

Ask a question

Before the appearance of ranunculus buds in a pot or open ground and directly during the flowering period, it is important to feed the plants with potassium, phosphorus and, of course, limestone. nine0003

Since the winter hardiness of this crop is low, if the ranunculus grows outdoors, it is better to dig up the tubers and harvest them for the cold season. Do this after the foliage has completely dried.

After the buds wither, it is better to remove the flower stalks. This will contribute to the long and abundant flowering of garden ranunculus. At the end of August, all shoots are removed to the ground.

Buttercups can thrive in full sun, but they prefer shade. This is especially true for varieties with bright buds. When grown in a shady area, the buds do not fade and flowering is longer. nine0003

The ranunculus flower does not like drafts and cold winds. Watering should be timely, but not too plentiful, otherwise the plant will get sick.

The fact is that ranunculus is prone to putrefactive infections, so you need to monitor the condition of the foliage. If mold appears on them, and the flowers begin to fall off, you need to treat the culture with a fungicide.

While watching the video, you will learn about growing ranunculus.

It is possible to grow your own ranunculus at home. In order for the plant to be lush and flowering, it is important not only to properly care for it, but also to use high-quality planting material. nine0003

Terms of planting ranunculus tubers at home

When to plant ranunculus tubers at home - from the end of February to May. You can grow buttercups for bouquets - for distillation, but then you will need additional artificial lighting for plants.

Preparation of ranunculus tubers for planting at home

To make the tubers grow faster and better, follow the advice of professional agronomists:

Planting ranunculus tubers at home

Prepare pots or containers about 20 cm deep. Put a layer of drainage on the bottom - vermiculite, expanded clay, fine gravel, coarse sand. Pour moist soil into the flowerpot so that its level does not reach the edge of the pot by 5–7 cm. Place the rhizomes with nodules down. Cover the ranunculus with earth so that it covers them no higher than 1 cm. Water gently. We recommend planting 3 - 5 plants in one flowerpot, at a distance of 10 cm, so choose a flowerpot taking into account the planting of several tubers. Place the landings in a well-lit area. Watch for watering, the soil should be moderately moist all the time, but avoid overflowing. The first flowers will appear in about two months. nine0003

Watering ranunculus for indoor growing

The most favorable conditions for growing ranunculus in pots: soil, light requirements

The substrate should be light, moisture-absorbing and neutral. Avoid heavy and dense soils. Drainage at the bottom of pots for growing buttercups is a must. Before planting - spill the soil with a fungicide solution, we recommend the drug Fundazol, this is necessary for the prevention of diseases and rot. Add complex mineral fertilizers to the watering of young plants, it will be convenient for you to use the Green Guy bright flower bed. Ranunculus need well-lit areas, but on hot sunny days, keep plants out of direct midday sun. An east and west window sill or terrace side works best. Plants can be placed anywhere where there is enough light, the intensity of flowering will depend on the degree of illumination. In partial shade, the ranunculus will not bloom so abundantly, but for a longer time. nine0003
