50 Red Castor Castor Bean Ricinus Communis Non_GMO Seeds ~ Chris's Garden

Red castor is thermophile and can live in dry, barren, and saline-alkali soil. It is very adaptive, and has good stress resistance and poor waterlogging tolerance. The optimum temperature for its growth is 68?82.4?. Except for winter, it can be planted in other three seasons. When the temperature of the soil 5 cm lower than the earth’s surface stably rises and passes 50?, the seed can be planted, with 20% as the optimum soil humidity. Start Castor Bean seed directly outdoors in a prepared seedbed after danger of frost has passed. Press the seed into soil, cover it with 1/4 inch of soil and keep the seed moist but not wet. With a temperature of 65 – 70F, germination is usually in 14 days. Before planting, dry the seed in sunlight for 3-5 days. Germination can be accelerated. Soak the seed in clear water or 86?water for 48 hours. After changing the water for 2-3 times, apply sand culture or put the seed in the incubator to accelerate germination.
