Recently in Tucson I came across another Texas Ranger that was in need of care. The owner was tired of the size and continual leaf fall mess it made.
This all took me back to my tree and shrub care training by my brother in law who is a Licensed Landscaper. He always told me to cut them down after fall and let them grow again. This maintenance keeps them small and offers a lot less leaf mess to clean up. (wrong)
Well, in my professional life and studies I have come to a different conclusion. The Texas Ranger (and relatives) are misunderstood mainly because they are over planted due to their ability to grow in any well drained soil. In fact they will get root rot in richer soils. So Tucson is full of Texas Rangers, all hooked to a drip irrigation system!
News flash, they only need to be watered once a month! This will control growth and keep them a little smaller. Please know that you will never know the beauty of a Texas Ranger if you prune it. It is not a plant to be pruned, if you must do it do a light tip pruning that encourages new growth, new growth produces new buds to bloom.
The TEXAS RANGER and its relatives are beautiful Shrubs, but most Tucsonians see them as messy plants never seeing them fully bloom to their potential. If you plant one please place it in an area it can grow in its natural shape, not interfering with structures, and water it once a month not daily on a drip. Working for years as a Tree Service in Tucson has allowed us to provide you with advanced info. I wish you the best and hope we all have a more beautiful TUCSON.
