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?

In my view the field could be plowed or the alfalfa could be killed with Roundup (or Roundup plus 2,4-D). Roundup and 2,4-D are considered foliar herbicides and would need to be applied before the plants are disturbed. If Roundup is used, we need to wait a week before tilling the soil to give the Roundup time to translocate through the roots. If Roundup and 2,4-D are used you will get a better kill, but would need to wait a week before tillage and three weeks before planting as the 2,4-D has some soil residual. In Weber County I prefer to have the new grass seeded by the middle of September, but have been successful at the first of October. Hope for a long fall.
Plowing would be the simple solution and does a pretty good job of killing alfalfa. In either case you will need to fight some alfalfa roots to get a smooth seed bed.

- My front yard has large patches of dead grass. Originally I thought it might be a result of grubs, but dug down and didn't see any larvae or grub worms.

- Last May I planted an eight foot Sub-Alpine Fir in my new yard. My soil is very sandy. We deep watered the tree once a week throughout the hot season. The tree never showed any sign of stress until now (March). The ends of the branches are turning brown. I know these trees are sensitive. What can I do to best ensure the tree survives?
- We moved two Moab two years ago. My husband wants to grow a nut tree on the southwest side of our house that is just bare dirt and gravel now. We also want a shade tree (no fruits or nuts) in our front yard that faces South/Southeast to give our house shade. I am originally from Utah County and I miss my trees! Is there anything comparable that would grow here in the clay?
- I have 30 acres of dry farm high on the west side of cache valley and would like like to cover it with many trees that are likely to survive and will eventually provide shade. What should I plant?
