Why do tree leaves turn brown in fall?

In the fall, trees break down the green pigments and nutrients stored in their leaves. The nutrients are shuttled into the tree’s roots for reuse in the spring. Some tree leaves turn mostly brown, indicating that all pigments are gone.

Why do some leaves turn brown before they die and fall off the plant?

Plants naturally use and lose water through their tissues each day. Leaf tips turn brown when that lost water can’t be replaced for some reason. This includes providing the plant with too much water, too little water or too much fertilizer. Root damage or distress also prevents roots from doing their job.

What happens to leaves when they fall off trees?

Dropping them gives the plant a fresh start in the spring, and the nutrients from the decaying leaves are recycled to help grow the next leafy generation. Interestingly, autumn leaves are not simply blown off trees but are separated from the plants in a highly controlled process.

Why do tree leaves go brown?

Brown tips or margins often indicate drought in spring or summer. Young growth is particularly susceptible. This is particularly common where dry weather follows spring planting, prior to new roots developing into the surrounding soil. The damage is often worse where exposure to wind dries out leaves.
