Citrus Trees Need a Good Soaking

Citrus needs to be watered more often than other fruit trees because of the relatively shallow roots, but don’t overdo it. Evenly spaced irrigations are the key to preventing fruit drop and splitting. A good soaking every two weeks is often recommended in summer. Leaves yellowing between the veins in summer are a sign of chlorosis. Cure by fertilizing with trace elements such as iron or zinc, available at nurseries.

Most plants don’t need fertilizing in summer. Notable exceptions include roses, warm-season lawns and summer annuals, which should be fertilized monthly. Anything confined in a container also needs regular monthly fertilizing.
