The rumor is still circulating in internet forums and specialist books that the yucca palm needs a lot of moisture, especially a high level of humidity. As a result, the hardworking house gardener diligently sprays his yuccas with the spray bottle and is amazed that they turn yellow. Most palm lily species do not grow in the damp rainforest, but in very dry areas of the world - as a result, they prefer it to be dry and warm.
Too much fertilizer
Over-fertilization also leads to yellow leaves. Fertilize your yucca every two weeks to once a month - and then only moderately with a liquid green plant fertilizer.
Too little light
Many types of yucca come from deserts or semi-deserts and therefore need a lot of light. These turn yellow leaves very quickly if they are too dark. But be careful: this does not apply to all yuccas!
If the yucca gets too tight in the pot, she will feel uncomfortable. She shows this - of course - with yellow leaves. Repot the plant into a larger container and fresh substrate as soon as possible.
Treatment options
If your yucca has yellow leaves, remove them immediately. Cut or pluck the leaves and then continue treating the plant based on the suspected cause. Yuccas that are kept too moist and over-fertilized should definitely be transferred to fresh substrate.
Tips
The yucca can also develop yellow leaves if the winter is too warm. The houseplant feels most comfortable during the cold season at temperatures of around 10 ° C.
