Satsuma Fruit Splitting and Leaf Curl: Water and Leafminer

A Texas gardener's satsuma fruit splits and drops; new leaves curl. Tree is in full sun.

Fruit Splitting

Caused by irregular watering. If the tree is dry and then receives heavy rain (or sudden heavy irrigation), the fruit skin can't expand fast enough and splits. Consistent moisture prevents this.

Leaf Curl

Curling new leaves are likely from citrus leafminer (Phyllocnistis citrella), a tiny moth whose larvae tunnel in leaves. Damage is cosmetic on mature trees but can stunt young ones. It's seasonal—worse in warm weather, diminishes in cold.

Organic Management

• Water deeply and regularly; avoid fluctuations.
• Apply Atomic Grow (organic) to deter leafminer and greening disease.
• No mulch under citrus—keep soil bare to reduce humidity and disease.

Full sun is correct for citrus.
