My vinca minor has numerous yellow leaves this year. My husband keeps dumping water on it, thinking it needs more since it is yellow and at some instances brown. Are we watering it too much, or is it missing a nutrient that needs to be added? HELP!

Overwatering can sometimes cause yellowing in leaves, and might even cause some root rot that would result in dead leaves. Check the soil moisture before watering again. The top inch of soil should feel dry, and the next couple of inches only slightly moist before adding more water.
Vinca minor performs best in shade. If a tree or other shade-providing structure has been removed, the leaves may be "sunburned" or scorched.
It also prefers soil rich in organic matter. Topdress the area with a fine compost to sustain soil structure and health.

- 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.

- When is the best time to seed native grasses such as streambank and western wheatgrass into an existing Kentucky Bluegrass lawn? Some of what I've read leads me to believe that it would be best to seed in late fall so the seed will germinate in the spring. But I wonder if it would be better to seed in early fall after stressing the KBG. I will also be seeding sheep fescue, but I've seen conflicting information on whether that is native or introduced. My goal is to have a lawn that can survive with no water, and stay green with very little water.
- I'm getting ready to plant grass in my back yard either this fall or in the spring. I'm wondering if dwarf fescue will grow well here in Springville, or if I would be better off planting bluegrass? I had dewarf fescue in Southern California and really liked it.
- I have a good number of my lawn customers that have a large amount of burmuda grass coming into their bluegrass lawns. I have use for 3 years a product call turflon ester, A Monterey product, containing Triclopyr at 61.6% at up to double the rate. I have been applying 3 applications per season with a backpack sprayer to spot spray the patches in the bluegrass. I am disappointed in my results. Please reply as to what to do to eradicate this problem as I think that is is very critical. I see it in most of the approx. 70 lawns that I treat. Where is it coming from??
