Growing Persian Buttercup
If you decide to add Persian buttercups to your collection, you will see that it is a delight to have them around. Although these blooming ornamentals have a dew mandatory demands for their healthy and happy growth, it is not as difficult to take care of them as you might think. But enough talking! Let’s get you more familiar with growing and caring for Persian buttercups!
When it comes to lighting conditions, the Persian buttercup will have the time of its life when it is planted in a location where it can get as much full sunlight as it can. In other words, plant this beauty in a spot that allows it to get at least six hours of bright and direct light on most days. This particular type of light exposure will help your plant grow and bloom at its best.
Temperature-wise, Ranunculus asiaticus is a hardy species only in the USDA zones 8 to 10. This plant thrives in cool spring weather and will naturally go dormant once summer temperatures go higher than 90 °F (32 °C).
Overwintering your Persian buttercup is on the priority list. If you live in a warm region and want to grow your Persian buttercups as perennials, all you have to do is leave them in place and allow their foliage to die back on its own at the end of summer. After this, you have to cut the remains back to the ground before the first sign of winter and also protect your plants with a layer of mulch.
Outside of the plant’s hardiness regions, you can grow them as annuals, or you can dig up the bulbs and place them in a cool room for winter, covered in peat moss. However, this method does not always work as we would want to. Because of this, in areas where winters are harsher, it is better to grow your Persian buttercup in pots and bring them inside during the winter.

Planting Persian Buttercup
In warmer areas, you can plant your newly-bought Persian buttercup directly outdoors in autumn. Yet, if you live in a colder climate, it would be wise to wait for the spring to bring some warmth before planting the bulbs. You can also start the bulbs in an indoor setting in containers about twelve weeks before the last frost date. In case you plant them in a pot, space the bulbs 3-4 inches (7.5-10 cm) apart from one another.
In terms of soil, the Persian buttercup prefers to grow in sandy or loamy substrates that come along with very sharp drainage. Moreover, you will have to choose a growing medium with a slightly acidic soil pH. If your garden soil is too heavy, you can amend it with peat moss or simply plant your companion in a raised garden bed. When it comes to indoor specimens, it’s important to plant them in pots that have drainage holes at the bottom.
Right before you plant the Ranunculus asiaticus bulbs, make sure you mix some bulb fertilizer or compost into their future growing mediums. Once the foliage shows up on your plants, you will have to fertilize them once every two weeks following the product label instructions. The best product for these buddies is a water-soluble fertilizer.
Regardless of the setting in which setting you are growing your Persian buttercup, whether it is indoors or outdoors, deadheading is mandatory in its caring routine. Keep in mind that you must deadhead the flowers once they fade to have a tidier plant and more bloomings overall. If you keep your Persian buttercup indoors, however, you will have to also trim its foliage to maintain a certain size and shape.
Watering Persian Buttercup
In general, bulb-growing plants must be soaked in water for a few hours before planting them to stimulate growth. When it comes to Persian buttercup, this is not a mandatory practice. But if you decide to soak the tubers, make sure you do not overdo it. It is more than enough to soak them for about one to four hours, as this will prevent mould from developing.
When you plant your Persian buttercups, we suggest you water the tubers well. After this, you should refrain from watering again until you notice the first signs of growth. This method will help you avoid issues like root rot. Once the plants have settled in their new environment, you can spoil them with drinks whenever their soil begins to dry out.
Persian buttercups are not as picky regarding humidity, and they usually thrive in humid environments. Still, very high humidity levels may cause root rot, which is a serious issue that will kill the plant with time. For optimal growth, provide your Persian buttercup with medium levels of humidity.
Propagating Persian Buttercup
With their spectacular flowers and easy-going nature, it is perfectly natural to want more Persian buttercups in your garden. Luckily, you can easily make more specimens through various propagation methods. The most popular and efficient ones are via division and seed. Let’s see what this is all about!
If you choose to propagate your Persian buttercups via division, your chances of success are really high. The first thing to remember is that this process is usually carried out in autumn, so you might have to wait for a few months before you can dig up the bulbs from their growing medium. You will see that, in general, many of these bulbs should have already created tiny seed bulbs or offsets.
In warm areas, once you dig them out, you can divide the bulbs using a sharp knife and plant each offset in its new location right away. This is not a problem, as winters are not as harsh as in other climates. It would be wise to plant them about two inches (5 cm) deep with the roots or ‘fingers’ pointed downward. Once this step is done, you will have to water the divided parts well and keep their substrates constantly moist by watering them once every couple of days. New shoots should emerge in a few weeks after planting.
In cooler areas, however, you will need to store the bulbs until spring to propagate your Persian buttercups. In autumn, before the first sign of frost, dig your plants out, clean off any excess dirt, and then store them in a cool, well-ventilated place. Place the bulbs in a box filled with peat moss or coir and keep the box away from direct sunlight exposure. Once the spring shows up, divide each bulb into as many sections as you can, then soak them in water for one hour. After this, you can plant them outdoors in the ground.
In case you wish to start your own Persian buttercups from seed, wait until the blossoms begin to fade, then cut them off. Allow the flowers to dry out for a week or so in a paper bag and shake the bag to knock the seeds loose. Next, you can start the seeds indoors a few weeks before the last frost day in your region. Sow the seeds on top of moist soil and place the container in a warm, indirect-lit spot. Germination will occur in two weeks or so, but you can transplant the seedlings to their permanent location only when they have four sets of true leaves.
Persian Buttercups Common Problems
Persian buttercups are plants that can bloom profusely, and they normally do so. If your Persian buttercups do not seem to produce enough or any flowers at all, there might be a problem related to their environment. First things first, Persian buttercups should receive about one inch (2.5 cm) of water weekly. Secondly, avoid over-fertilizing your plants since high nitrogen levels can promote leaf growth and no blossoms. Lastly, mulch your Persian buttercup with bark, straw, or cocoa hulls to maintain proper moisture levels after watering it.
Ranunculus asiaticus a.k.a Persian buttercup is a bit sensitive in terms of pest infestations. Intruders like spider mites, aphids, and leaf miners will sometimes be tempted to munch on its leaves. The most common signs of infestation include yellowish-brown, withered, and splotchy foliage. If you want to get rid of leaf miners or spider mites, you must use an organic pesticide. You can wash the aphids away by spraying your plant with a mixture of water and dish soap. You might have to repeat the process a few times to ensure that all the aphids are removed.
Likewise, Persian buttercup plants can encounter some issues with fungal diseases like rust, powdery mildew, tomato spotted wilt virus, or necrotic spot. When your plant is affected by one or more of these diseases, its leaves will curl and turn yellow. The best defence against these problems is none other than prevention – make sure you provide the plants with excellent air circulation and water only the bulb, without the plant itself. Another important thing to remember is that a common cause for many different problems is getting the foliage and the flowers wet. By keeping the plant dry and watering it at the base, you reduce the chances of a pest infestation or a fungal infection.
Ranunculus asiaticus a.k.a Persian buttercups are perfect additions to any type of garden. If you live in a warm climate, you can grow these pretty flowers outdoors as annuals or perennials. If you live in a colder climate, you can still grow them, but you need to keep them in containers that you can bring inside to protect them from the cold.
These gorgeous flowering plants are a must-have in every collection that requires a dash of colour this summer. What makes these flowers perfect for any garden is their overall easy-going habit. You don’t have to be an experienced gardener to enjoy their beautiful blooms, as these flowers will only require water and light.
If you do not have a Persian buttercup in your garden or home, this is a sign for you to get into action. If you already own one or more, share your experience with us in the comments!
