Why are the bottom leaves on the oleander turning yellow and falling off? The top of the plant is healthy and blooming.

As evergreens, oleanders constantly replace their oldest leaves with healthy new leaves. Those at the bottom of the plant and towards the center are the oldest and will be shed during the growing season. They will be replaced if you prune your oleander back after each bloom cycle. Pruning forces new growth at the bottom and towards the center of the plant. If you do not prune to help renew your oleander, it will develop bare lower stems. If you'd rather have a thick, full, bushy oleander, prune it after the flowers fade. If you want a tree type oleander, don't prune it and the main stems will be bare.
