Overwatering and underwatering can cause surprisingly similar symptoms in fruit trees, which makes it easy to misdiagnose the problem and make it worse. Here's how to tell them apart.
Leaf Symptoms
Underwatered trees typically show dry, crispy, browning leaf edges and overall wilting. Overwatered trees more often show soft, yellowing leaves that may drop even though the soil is clearly wet.
Soil Check
The simplest test is to check the soil a few inches down. If it's bone dry, the tree is underwatered. If it's soggy or waterlogged, you're dealing with overwatering, possibly compounded by poor drainage.
Root Health
Overwatered trees are more prone to root rot, which can cause a sour smell in the soil and mushy, dark roots. Underwatered trees typically have dry, brittle roots but no foul odor.
The Fix
For underwatering, establish a consistent, deep watering schedule. For overwatering, cut back watering frequency and improve drainage, whether that means amending the soil or moving a container plant to a pot with better drainage holes.
