Maple leaves can turn yellow prematurely for a variety of reasons, including drought stress, nutrient deficiency and sunburn. This can be remedied by regular watering, fertilizing with compost and horn shavings or moving older trees to the shade in strong sunlight.
This is why maple leaves turn yellow prematurely
Don't worry about yellowing leaves for a long time, but carry out an analysis of the causes. The following overview summarizes the most common triggers for the problem with tips for the solution:
- Drought stress: Water maple thoroughly immediately and water more frequently from now on
- Nutrient deficiency: fertilize at least once a year with 3 liters of compost and 100 g of horn shavings per square meter
- Sunburn: transplant within the first 5 years, shade older maples in full midday sun
If a maple tree in the pot suffers from yellow leaves due to drought stress, let water run onto the root ball until it runs out of the opening in the bottom. Ideally, you can remedy nutrient deficiencies in the pot with a liquid fertilizer for green plants (€6.00 on Amazon). Changing the location to a partially shaded place helps against sunburn.
