Ilex Plant Care

Established specimens tolerate pruning, but little is required. Prune for holiday decorations or in early spring just before new growth begins. Shape for hedges with shears.

Plantable Pots

Our plants are grown in 3.5x3.5x4” plantable pots. Made from 100% biodegradable coconut husk fibers (coir), these pots have tremendous advantages over plastic pots. With better air exchange, this "breathable" pot fosters robust root growth and reduces transplant shock since you can plant the pots directly in the ground. The pot naturally becomes part of the soil on its own over time—no composting required—and since they're made from a renewable resource that requires very little energy, they're earth-friendly too!
