LECA FOR HOUSEPLANTS?

HORTICULTURE TOPIC: What is LECA and Should It Be Used for Houseplants

Horticulture Chair Nancy Percivall discussed LECA (Lightweight Expanded Clay Aggregate) and whether it should be used for houseplants. 

​LECA is a growing medium made of porous clay pebbles. These small, round balls absorb and retain water while allowing air to circulate around plant roots, reducing the risk of root rot. Unlike traditional soil, LECA doesn’t break down over time and is reusable, making it an eco-friendly option for plant lovers.

LECA is an excellent choice for certain plants, especially those that thrive in semi-hydroponic setups, like pothos, monsteras, and orchids. It helps regulate moisture levels and prevents overwatering, a common problem with soil-based growing. However, it requires a different care routine—plants in LECA need a nutrient-rich water solution since clay pebbles lack natural nutrients.

If you enjoy experimenting with new plant care methods and are comfortable with hydroponic principles, LECA can be a great alternative. However, if you prefer a more traditional approach, soil might still be the best option for your houseplants.
