Detailed explanation-1: -Leaf tips turn brown when that lost water can’t be replaced for some reason. Ideally, water flows from plant roots through stems and waterways until it finally reaches leaf tips last. But when water’s limited, other plant parts get served first; tip cells lose out and die from a kind of drought.
Detailed explanation-2: -In autumn when it starts to get cold, some plants stop making chlorophyll. Instead, those plants break down chlorophyll into smaller molecules. As chlorophyll goes away, other pigments start to show their colors.
Detailed explanation-3: -Your Humidity Level Low humidity and dry soil can cause leaves to droop and brown on their edges, which can later be followed by entire leaves turning yellow, brown, or shed completely. Your Money Tree will appreciate a boost in humidity from regular misting using a mister, a humidifier, or the use of a pebble tray.
Detailed explanation-4: -The fall leaves’ pigment is susceptible to sunlight. If you have a bright, sunny fall, your tree will be a little blah because the pigments are breaking down quickly. If your leaves end up brown, it is because of cold. While leaves changing color in the fall are dying, they are not dead.
