GROWING INSTRUCTIONS

Start the Castor Bean seeds indoors about 6 weeks before the last expected frost. Plant the seeds in pots, covering them lightly with soil, and keep them in a moist but not overly wet environment. Use two seeds per pot and thin to the strongest seedling when they reach about 2 inches tall.

Once the seedlings are established and the danger of frost has passed, transplant them outdoors. Space them about 6 feet apart in a location that is sheltered from strong winds. Gradually harden off the plants by exposing them to outdoor conditions for a few hours each day over a week.

Castor Beans require regular maintenance for optimal growth. Fertilize every two weeks with a balanced fertilizer and liquid seaweed. Although the plant is toxic and not suitable for consumption, it provides a stunning ornamental display with its large, tropical foliage.
