Why Guava Leaves Turning Yellow?

Most plants will turn yellow as a sign of stress – if the weather is exceptionally hot or cool and/or wet or dry, this could be the culprit. There is also a chance that the yellowing leaves are a symptom of nematodes. There are a number of nematodes that attack guava tree roots.

Do guava trees need a lot of water?

They prefer full sun. Guavas have survived dry summers with no water, although they do best with regular deep watering. The ground should be allowed to dry to a depth of several inches before watering again. Lack of moisture will delay bloom and cause the fruit to drop.

How do you stop yellowing leaves?

With too little water, plants can't take up essential nutrients. Yellow leaves result. To fix or prevent water issues, start with porous, well-draining soil. If you grow in containers, choose pots with good drainage holes and keep saucers free of excess water.
