Summer pruning is a confusing management practice. It starts around late spring or very early summer and may continue all summer long. Its purpose is twofold: keep the tree smaller and reduce the winter pruning workload. Summer pruning focuses on removal of new growth only from existing productive trees. Summer pruning allows the tree to invest new growth where it senses light and a "hole" in the canopy needs to be "plugged". When fruit trees are meant to stay small, summer pruning can be a valuable management tool. Learn all about it on this episode of Desert Horticulture.

I'm not a huge fan of growing citrus at the middle elevations in the Eastern Mojave desert but it can be done. Citrus production is best done in southern Arizona and at lower elevations, warm parts of Southern California such as Riverside and Orange counties and along coastal regions such as the Galveston area of Texas. Citrus in our part of the world is best treated as a hobby; some years you get a good crop and other years you don't. Because of global climate change and Covid, citrus is become very popular for home gardens. This episode of Desert Horticulture focuses on what kind of citrus to buy, wear and how to plant these small to medium-sized fruit trees.

Wind can cause two types of damage to plants; visual and nonvisual damages.

All this and more on today's desert horticulture.
