Castor oil plant: growing from seeds, when planting seedlings
Castor oil plant can grow from seeds fallen into the ground, but it is also bred by growing seedlings. In central Russia, seeds begin to prepare for planting from mid-April. In the southern regions this can be done a month later. For seedlings to remain healthy, she needs a ten-hour daylight. It can be provided with the help of additional lighting.
Before sowing, the seeds must be processed to get rid of the thick shell, which makes it difficult for the seed to exit. Scarification takes place with sandpaper. She treats the surface of each seed. After the procedure, the germination process will be accelerated several times. After processing, the seed material is soaked in a growth-promoting composition or ordinary water for a day.
Castor seeds
For landing, plastic containers are used. They are half filled with nutrient soil. Then the seeds are laid out on the surface, pressing in 20-30 mm. Scarified castor seeds germinate on the third or fourth day.
House seedlings are developing very actively. After the first leaves appear, it is necessary to rearrange the containers in a cooler, but well-lit place.

As the flower grows, the capacity is filled with additional soil. This is done until it is full. If castor oil plants, the planting and care of which is quite simple, develops too quickly, it requires additional transplantation into a more spacious pot. The size of the sprouts before planting in the soil should not exceed 100 cm in height. When the threat of night frost passes, the plants land on the street. To reduce the likelihood of injury to the root system, it is best to do this with a lump of earth.
