Q
We just planted a maple tree in our back yard and noticed today that almost every single leaf has large circular spots that appear to have been "eaten" out of the sides of the leaves. I've read about a tar disease, but I don't really see the tar on the leaves. What could it be and is there something we should do about it?
Answer(s)
A
Most likely this is caused by leaf cutter bees that cut out circular discs and store them for food. They often store these discs in cracks and crevices in house siding. It doesn't do any serious harm to the tree.

- 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?
- We would like to know if Legacy Buffalo Grass would work alone in our back yard or whether we should mix it with something else. We are looking for a low water, low mowing frequency product that will work well with dogs who live inside but do run hard and play on it. We also like the pollen free feature of Buffalo Grass as one of our dogs has allergies and chews at her feet after being outside. We currently have mostly Bermuda grass and are in the process of killing it off. We live in Hooper and our yard is approximately 1/2 acre with a few young trees along the borders (which of course will get bigger). The trees are Mulberries, Cottonwoods, Red Oaks, Tulip Trees and Austrian Pines. Suggestions for mixes we have heard are Sheep's Fescue and Bella Bluegrass. Also, is there a place in Utah where we can buy these grasses so we don't have to pay a large price for shipping?

- My Grandmother has several apple tree saplings that she has grown from seeds. She has offered one of the saplings to us. We want to know what time of year is the best for transplanting? Should we dig it out this fall and keep it in the garage until spring? Or could we transplant at the end of September? Is there a transplanting guide? Thank You For Your Time!

- We bought a house with horrible "goat head thorn" problem, all summer we have been pulling them out and collecting the thorny seeds as much as we can. We are now looking to plant grass seed.
