I just moved to South Jordan and I have clumps of grass pok-a-dotting my lawn. Some say it is crab and others say Johnson. The clumps are hard and raised.

There are several clump grasses that can be "weeds" in lawns. Tall fescue is a perennial clumping bunch grass with wide blades, dark green shiny leaves and a link to images of tall fescue http://www.invasive.org/search/action.cfm?q=tall%20fescue . Crab grass is an annual plant that has a shallow fibrous root system with a seed head with 3 to 4 finger-like spikes.
Johnson grass - here is link to selected images of Johnson grass http://www.invasive.org/browse/subject.cfm?sub=3075
So perhaps from these pictures you can determine what you have in your lawn. Or you can come by our office with a fresh sample for identification. We will have Master Gardeners on Monday August 25 from 1 pm to 4pm at 2001 South State Rm S1008 hold a plant problem diagnostic clinic to help folks identify their plant problems and provide management recommendations.

- A landscaping company planted 6 jaquemonti birch in my yard at the end of May. Two of them recently began developing darkish brown leaf spots in the center. They are getting plenty of water. On one of the leaves I found very tiny black insects. I did not find insects on any of the other leaves. What could the problem be and what should I do about it. I picked the infected leaves off that I could reach. I also collected the insects.
- We tilled our garden and planted peas and lettuce about three weeks ago. Nothing has come up yet. We were talking to our neighbor yesterday, and he told us that about 30-40 years ago, in a fit of vexation, the former owner spread an industrial strength soil sterilizing chemical on the area in which we planted our garden. He further explained that weeds have only started to grow in that area in the past 5-10 years. This information has caused my wife to give up on trying to cultivate this area. Should we give up? What can we do to amend the soil in this area?
- In the vegetable fact sheets it make watering suggestions such as "water 1-2" per week" how much water is 1-2" per week? Also, Can I use blood meal for nitrogen to side dress tender plants?
- I want to plant raspberries in my garden next spring but am confused. Which does better in Cache Valley: summer- or fall-bearing? The USU pub on raspberry production (HG/2004-16) says plant only Haida or Malling Joy, but I haven't found anything about these species on the web. Is this statement still valid? If so, are they fall- or summer-bearing? If not, what is your species suggestion?
- Last summer I made some strawberry jam which I water canned in pint jars according to the directions in the pectin box. It seemed that all the lids sealed (they all popped). Now, though, the jam doesn't look quite right to me--it's a bit brown, especially toward the top of the jars. I'm a little wary of eating or even trying it. What could have caused this? Should I throw it out?
- I have mexican fruit flies that lay eggs and hatch larve in my apples and cherries. They are larger than reqular fruit flies and have black and white striped wings. When should I spray? What should I spray with?
- My husband mistakenly put fertilizer with a broad leaf killer in it on our garden. Is there anything we can do to grow things this year? Everything has died sadly.
- A friend has recommended an Epsom salt solution for my garden plants. How are Epsom salts used here? I know they add mag to the soil if it is depleted but I didn't think they were used in alkaline soils... do they have any benefits? Will they help me grow blueberries etc., stuff that needs acidic soil? Research says that Epsom doesn't change the ph much but I know sulfur is good.
