How to Fertilize Lily of the Valley

About Lily of the Valley

Lily of the valley (Convallaria majalis) is a perennial herb with sweetly fragrant, white bell-shaped flowers in clusters. Its rhizomatous roots spread via underground pips, forming colonies. Thrives in shade with proper fertilizing.

Fertilizing Schedule and Method

Step 1: Choose the Right Fertilizer

All-purpose, slow-release organic fertilizer with 5-10-10 or 6-12-12 analysis. Plan two applications: after blooming (late spring/early summer) and before winter dormancy (late fall).

Step 2: Spring Application

Wearing gloves, sprinkle fertilizer over soil around plants (not on foliage). Rate: ~2 lbs per 100 sq ft.

Step 3: Incorporate

Lightly scratch into topsoil with a garden rake to "anchor" fertilizer.

Step 4: Water In

Water gently but thoroughly until soil is moist (not ponding). A sprinkler on a hose works well.

Step 5: Fall Application

Mix 1 part fertilizer (same analysis) with 2 parts organic compost in a bucket.

Step 6: Top-Dress

Spread the mix over the planting area. It breaks down slowly, enriching soil for spring growth.
