Frequently Asked Questions

Why do leaves turn yellow and fall off?

Leaves turn yellow and fall off as a natural process of a plant's life cycle. As the days get shorter and the weather gets cooler, trees and plants prepare for the winter by slowing down their food-making process. This reduction in chlorophyll production allows the hidden pigments of yellow, orange, and red to become visible, resulting in the characteristic autumn colors. Eventually, the leaves wither and fall off, making way for new growth in the spring.

What causes leaves to turn brown and crispy?

Brown and crispy leaves can be a sign of dehydration, disease, or pest infestation. If the soil is too dry for an extended period, the leaves may turn brown and crispy as a defense mechanism to conserve water. Fungal diseases, bacterial infections, or pest attacks can also cause leaves to turn brown and crispy. It's essential to inspect the plant carefully and adjust its care routine accordingly.

How can I prevent leaves from turning yellow and falling off?

While it's impossible to completely prevent leaves from turning yellow and falling off, you can take steps to promote healthy growth and extend the life of your leaves.
