You should NEVER prune your trees like this! #trees #topping Topping a tree is not a good idea. Most of the time, topping is done to reduce the size of the tree's crown without regard to its health. Sadly, despite rese...

Do you have trees in your landscape that have lost some of their vigor of years past?

The last 3 years have been extremely hard on trees. The historic freeze of 2021, the almost-as-bad freeze of 2022 which was followed by a drought, and then the horrible drought last year in 2023. This email is just a heads up to our valued tree-owners who want to do their best to preserve their landscape. As the spring has progressed we have seen many trees bud early, which is a great sign! Hopefully the weather this year will be milder, and can give us even more relief; but for those trees who have not leafed out well, show signs of rot in areas, or who affected by early spring insects, NOW is the best time to do something. Below are some common issues we are seeing this spring and what do do about them:

- Scales: they present as small white spots (typically on crepe myrtles). Spraying infected areas on smaller trees is effective, but on larger trees, and trunk injection may be necessary to save the tree. Treatments last for an entire growing season
- Die-back on Oaks: We are seeing this mostly on Red Oaks, but also on some of the Texas Live Oaks. Depending on how severe it is, we recommend removing the dead wood, and either a deep-root fertilization, AND/OR a PHOSPHO-jet trunk injection to give the tree an immune system boost and dose of fungicide.
- Bark fall-off: Some mature trees slough-off old bark as new bark is formed during a growing season, and there is nothing to worry about. On some species, this could be a sign of freeze damage, or a lightning strike. There are many different ways to treat the issue (if it needs treating at all). Best course of action is to book an inspection with an Arborist.
- Chlorosis: Yellowish leaves that are under-developed. Often seen on maples and oaks. Can be helped by deep-root fertilization or a combo MnJet-fe Trunk injection combo with a growth regulator in more extreme cases to help the tree get the nutrients that it lacks quickly.
