Light
Shamrocks love light. Even artific all clovers are shamrocks ial light is beneficial. They do best with a few hours of full sun, but if that’s not possible try 12 hours of artificial light per day in the winter. Shamrocks will start to grow tall and thin if they aren’t given proper light.
Water
Let your shamrocks dry slightly between watering. The soil needs to be just barely damp. If the leaves turn yellow – particularly the lower, inner leaves – that means the shamrocks have gotten too much water. Shamrocks can wilt if they are too wet or too cold; they can also wilt if the root system is too dry. If they start to droop, they need water.
Fertilizer
Shamrocks only need to be fed when they are actively growing. During the Winter and Spring use a liquid or water-soluble fertilizer monthly. Cut back to every other month once your plant goes dormant.
Resting
Shamrocks need to go dormant for the overall health of the plant and to encourage the best blooms. This typically occurs in the summer. It is best to place your plant in a dark, cool place for a few months after it’s reached its prime blooming. Stop watering and fertilizing during this time, and your Shamrock should bloom again in the Winter.
