When buying Ranunculus, the tubers will be challenging and dry. Some gardeners like to water the tubers before planting, but there are some risks.

If the tubers remain wet for a long time, they will rot and not grow. It is okay to plant them as they are. They will absorb water from the surrounding soil and grow well.

It would help if you ensured that the land around them was not soggy. Persian buttercups do best in well-drained, light soils.

They like a bright and sunny place. They do not do well in a hot and humid environment.

10. Six steps to planting Persian buttercups outdoors

# 1 – Choose a slightly elevated, well-drained spot that gets at least 5-6 hours of sun a day. The site should have light, airy soil with a neutral pH level (pH 6 to 7).

If your soil tends to be clayey, it will be necessary to correct it or establish a raised bed, as these plants do poorly with poor drainage.

# 2 – Before planting your lamps, it is a good idea to spread bone meal and bulb fertilizer in the planting area.

Follow the package directions for the bone meal, but use only half the fertilizer per the manufacturer’s directions. Add an inch or two of organic matter (e.g., compost).

# 3 – Turn the soil entirely over to a depth of 9 “-12” inches. Work all the soil corrections thoroughly.

# 4 – Water well before planting the tubers and wait 24 hours.

# 6 – After placing the tubers, cover them with soil and cover them a lot with straw, coconut shells, or tree bark.

It will help the soil retain moisture. Do not water again until the tubers sprout.

Another way to start Persian buttercups is to grow them from seed indoors late winter.

Ranunculus seeds are tiny and should be sown on the surface of a very light patch made of peat, an initial mix of sterile seeds.

Since the Ranunculus seeds will soon found, place the seedling tray in a light, airy place with a constant temperature of around 50 degrees Fahrenheit.
