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.

Thank you for your inquiry regarding the weed in your alfalfa field. I consulted with Dr. Steve Dewey and unfortunately neither of us can appropriately identify the weed from the description provided.
Since identification is the most important "first step" in controlling this problem weed we need to be assured that we have properly identified this plant before we suggest some control measures. May I suggest the following:
1. If possible contact your local county agricultural agent and ask him/her to help you make a positive identification. Many of the county agents in Utah are very good at plant identification and they should be able to get a good identification to common name if not to genus and species.
2. If the county agent does not recognize the weed have them take digital photo of the plant. Many of the agents are very skilled with the digital camera and they should be able to get some good pictures that they could send to me for identification.
3. After we have made a proper identification I think I can give you some specific ideas for successful control practices.
I regret that I am not able to be more specific and helpful and this time but will be happy to assist you further when we know the name of the weed.

- What are the differences and advantages or disadvantages of soil amendments? Specifically Perlite (expanded silicous rock), Vermiculite (expanded mica), Utelite (expanded shale).
- The leaves of our sweet cherry tree have yellowed and our falling off at an alarming rate. This started two weeks ago and in another week ALL the leaves will have dropped except for a few on the tips of new growth (i.e. water spouts). This happened last year to two of our other sweet cherry trees. They did NOT come back this spring. Dead! The trees are 25 years old and pruned yearly. I've been fairly diligent about spraying (dormant oil, fruit fly, and borer) for the six years I've owned the house. At times they have shown signs of borer (or other insect) damage since there has been gumming spots on the trees. When I bought the house I removed the grass around the trees (not quite to the drip line,but a about four feet from the trunk. The trees get water from the lawn sprinklers, but I regularly (every 2-3 weeks) let a hose run water around the tree and soak in for a couple hours. When I fertilize the garden (commercial IFA garden chemical fertilizer)I toss a couple handfuls at the base of each tree. So some fertilizer about twice a year. The soil around the house is mixed. I would guess that most of it is moderate clay. We live on the edge of the bench not far from the mouth of Hobble Creek Canyon. If I had just walked into the yard, I would guess that the trees were getting too much water (yellowing leaves) instead of not enough water (dry crisping leaves). But I really don't water the trees that much and not at all in the last couple weeks when this yellow & leaf drop started. My only other clue is some leaves have brown spots. About the time we bought the house, a neighbor had a cherry tree drop most of its leaves and they were told (USU ext?) that it was a fungus; they sprayed and saved the tree. They've moved so I can't ask them specifics. I don't remember if the leaves had yellowed and then dropped. Too long ago. Help?
- How can I get rid of Bur Buttercup? We have tried poisons over the past few years with little result. This year we tried a pre-emergent with little to no results. What can we do do get rid of them?

- I have an apricot tree that is so heavy laden with fruit that it broke a major branch yesterday leaving me with about a half bushel of partially ripened fruit. Can any of it be saved? What should I do?
- I have two maple trees in my parking strip. I believe they are the Autumn Blaze variety. They have a light green to yellow small leaf. The leaves are starting to die as if it needs water. They are spotted and turning brown and brittle. The branches are still green when I scrape the them. I do not think it is under heat stress since June has been mostly wet. We spoke with someone who lives about a mile from us who had the same problem last year and now the top of his tree is dead. We did see two other trees in his neighborhood with the same problem. It looks as though next year we may have the same dead trees if we do not do something to prevent them from dying. Can you tell me what is wrong and what I can do to save the trees?
- We bought a house that has quaking aspens around the perimeter of the yard. About half of them are dying or are already dead. What can we do to prevent the rest of them from dying, and what should we do with the dead trees?
- My newly sprouted green bean plants are getting small to medium holes in the leaves. Could this be from pests or the heavy rain in East Millcreek?
