Why do maple tree and burning bush leaf edges turn brown in mid-summer?
Rate This FAQ
Leaf scorch. During sunny, hot, dry, windy weather, excessive transpiration from plant leaves can lead to scorch. Plant cells furthest from water-supplying veins may dry to death, turning the tissue brown. Leaf scorch is worse when leaf tissue is already weakened, as from iron chlorosis. Leaf scorch may also result from root rot (over-watering), salty soil or poor-quality irrigation water, or damage to the roots or trunk.
Recommendation: Rule of thumb, when top 2 – 3 inches of soil dries out around the plant, water deeply. Cover the entire tree root zone as well as possible, applying about 1 to 2 inches of water that soaks in gradually. Mulch 2” – 3” deep over entire root zone to retain soil moisture and eliminate competition from turf.

- I am an architect, working with a client who wants to hydroseed a 2.5 acre parcel for use as a softball field. The area is currently planted in alfalfa. There will be some regrading (both cut and fill) of the field that will be required. The client would still like to hydroseed this year, likely near the end of September. Do we need to call for the alfalfa to be treated with a herbicide? If so, what is the process, and what herbicide should be used? Is there a waiting period between application of the herbicide and the hydroseeding? Must the herbicide be applied to the above-grade plants, or can the site first be cleared, then the herbicide applied to the gound and roots?

I have been applying 3 applications per season with a backpack sprayer to spot spray the patches in the bluegrass. I am disappointed in my results.
