Mushroom Cultivation Methods and Solutions for Yellow Spots on Clivia Leaves

Yellow Spots Appear on Clivia Leaves

Yellow "pockmarked" spots often appear in the middle part of Clivia leaves, caused by soil that is too dry or too wet, or by applying fertilizer that is too concentrated, or by applying "raw fertilizer" that has not been fermented and decomposed. In addition, in hot weather, if a potted Clivia is placed in a stuffy, unventilated spot or exposed to the blazing sun, together with bacterial infection, yellow spots will appear: first the leaf turns yellow in patches, and eventually the entire leaf withers and turns yellow.

Prevention and control methods:

① When fertilizing, prefer dilute over concentrated, and follow the principle of applying thin fertilizer frequently.

② In hot weather, potted Clivia should be placed in a semi-shaded, cool, ventilated spot, and fertilizing should be suspended.

③ The potting soil should not be too dry, nor too wet.

④ Immediately cut off the leaves with yellow spots to control the spread.
