Proper Steps For Planting Rhubarb Seeds

Growing rhubarb from seed is simple, but few steps need to be followed. Start by preparing the soil, which should be well-draining and full of organic matter. Sow the seed after the last frost in spring 1/2 inch deep and 2 inches apart.

Then, keep the soil moist by regular watering. Once the first leaves appear, add a balanced fertilizer. After the seedlings grow to 6 inches, thin them, leaving the strongest ones spaced 12 inches. In two years, the plants will be mature enough to produce stalks.

Harvest them by pulling rather than cutting, leaving 1-2 stalks intact. Remember, rhubarb loves sun but tolerates partial shade. By following these steps, you can enjoy homegrown rhubarb all year round.

Caring For Rhubarb Seedlings

Mature rhubarb plants need season-appropriate care, including watering, fertilization, and removing flowering shoots to direct energy to the stalks.

Additionally, regularly check for pests and diseases and take immediate action if needed. By providing proper care, your rhubarb plants will thrive and reward you with bountiful crops.
