Hi, I have a lot of two year hybrid poplars that we've planted for a wind break and the leaves near the trunks are beginning to turn yellow. I've read that this can be because of lack of water or too much water or not enough fertilizer. It's July and we water them every day because of the 90+ temps. Any suggestions?

It sounds like too much water. I prefer deeper and less frequent watering, normally established trees need a good soak every week to 10 days. Also, frequent watering does not force the tree to grow deep roots that go after water and will sustain a tree through hot days.
Frequent watering also washes away the nitrogen so a tree will rob nitrogen from older leaves to keep growing. This best explains your described your situation. If it were not enough water you would see browning of outer leaves especially those on the south and west side that get the brunt of wind, sun, and warm temperatures. Slowly cut back on your watering intervals but increase the amount. let the hose run longer but put more days between watering. We don't normally encourage fertilization of trees, especially not in the heat of the summer where it encourages lush green growth. Spring and late fall would be better.

- I have some problems with native Juniper trees dying(25 ft average height). They start turning yellow (chlorosis has been ruled out) then brown on south side first, then slowly spread to north end of plant. I have cut down one and found no signs of insect damage or disease. Only trees located next to a dirt road(South of trees) are currently affected. They started changing in color last summer. The county does spray for russian thistle on road. Yet no other trees seem to be affected. Can you provide other possible reasons or someone that may be able to come and see them (test them)?
- We have a weed in our hay field that is choking out the field in quite a large area. The weed has a hard stem with heart shaped leaves about 1/4 to 1/2 inch in size around the stem leading to seed pods that look like flowers that are hard and have a seed in them. The seed is red and the husk around them is green when the seed leaves the husk is white, stem is hard green and stick like.
