How to Prune Green Spleenwort?

(Asplenium viride)

Green Spleenwort, also known as Bright-green Spleenwort

A perennial fern known for its delicate, green fronds, green Spleenwort thrives with minimal pruning. To maintain vigor, remove dead or damaged fronds at the base in spring, just before new growth emerges. This timing promotes healthy foliage and allows the fern to benefit from its natural growth cycle. Regularly trimming away older fronds can reduce disease risk and improve air circulation. Pruning outside of the recommended seasons—spring, summer, and fall—can stress the plant.

What Are the Benefits of Pruning Green Spleenwort?

Pruning green Spleenwort encourages vigorous growth by removing dead or damaged fronds, ensuring better air circulation and light exposure. Trimming helps maintain an aesthetically pleasing shape, ensuring green Spleenwort stays compact and healthy.

What Is the Best Time for Pruning Green Spleenwort?

Spring

Summer

Autumn

During Spring, green Spleenwort's growth cycle is entering an active phase, making it responsive to pruning and allowing it to heal quickly. Early Summer is suitable as the plant is still growing, and pruning can shape its growth without causing stress. Fall is effective for removing any dead or damaged fronds post the growth season, preparing green Spleenwort for winter without affecting new growth, which is minimal in this period.
