Bindweed

What is the best way to kill bindweed in my landscape bed? It is creeping up through my mulch. There is a lot of it in my lawn at the edge of the landscaping bed as well. I've read a lot of conflicting information on how to get rid of it. Pull it, don't pull it, pull it then apply RoundUp on the broken vine, let it grow out then brush RoundUp on the leaves...I'd like an official verdict from an expert please!

I had a small invasion of bag worms last year on my arborvitae. I want to prevent this and do not want it to spread to my other shrubs. The arborvitae are very tall so cutting the bag worms out is not possible. Can I spray them? If so when and with what spray? Thank you so much. PS. I enjoyed your performance at the Advanced Training seminar yesterday!

Trouble with Ice Plants

I had a beautiful blooming season for some three year old Ice Plants. Suddenly, it appears certain sections have collapsed. I checked under the area, and much of the soil is gone. Something like this happened last year, and I thought it was too much water... but it was this same issue. I added soil under the areas affected covering the exposed root stems and it took off! What is causing the problem? I have a ton of "night crawlers" moving through the beds; could they be the culprit? It seems there are high spots - I've noticed that in other gardens with a lot of worms. It seems an unusual problem, most folks would love to have the worms, but I wonder if they are the problem? They move a lot of soil around, is this it? It seems the plant grows over itself, as it is in somewhat of controlled area. HELP! and thanks so very much. I've been a member of the Gardens for 100 years (actually, nearly 30 years) , and this is the first time I've availed myself of your services. Thanks in advance for your help! Ron Lehmann

Leaves falling from Monterrey Oak

I have 2 Monterrey Oak trees about 25' tall (planted in 2003). They lost leaves in the fall and sprouted new leaves about 6-8 weeks later - normal process. During the last month, one of the trees has been losing a lot of leaves - about 1/4 leaves have fallen off. I'll send a pic of some leaves (still attached to the tree). The other tree is now losing leaves. I sprayed Triazicide on both trees a couple days ago. A few years ago both trees had bore worms and I used a product with permethrin to resolve. No signs of bore worms right now. Any idea what is causing the leaves to fall off?

Russian Sage not leafing yet

I live in Evergreen at 7,600 ft. My Russian Sage is 11 years old, it has been fabulous and growing every season. I pruned this spring as I always do, but it is not leafing yet, and shows no signs of life, when I snap a pruned branch, it isn't super brittle and dry, but is becoming that way. Is there any hope??

termites in heating vents

My house is built on a slab. We had it treated for termites and this year they swarmed up out of the heating vents. There aren't any plans of the house to detail where the vents and plumbing of the house is located. How can the company (that guaranteed their work) treat to remove the termites? They say that they can retreat the perimeter but without plans there really isn't anymore that they can do. Thank you

Soil Test for Mill Creek Watershed Council

To who I may concern, The Mill Creek Watershed Council of Communities has received a grant to educate members of the community on how their law care practices effect local waterways and how small changes in their law care practices can make large impacts on reducing nutrient loads in local waterways. One of the first steps in this project is to get baseline soil samples from residents. I know that MSU sells soil tests, and gives a discount for more than ten samples, but if we are looking to buy a couple hundred tests. Also, we are only looking to test for just the components of fertilizer (Nitrogen, phosphorous and potassium), so is there a way we could use MSU’s services for that and not all 18 tests. Furthermore, we are looking to get the results as well as giving them to the residents, so is there any way we can both get the results? We would love to work with MSU in order to make our project successful. Thanks, Olivia Williams

Safe to fertilize after planting?

Hi- My wonderful husband planted our garden before we got our test results! Is it still safe to apply these fertilizers in between rows? Which would you recommend to not hurt the plants? Our options are 22-0-22, 12-0-12, or 3-0-3.

College Station Hedge?

At The Episcopal Student Center at Texas A&M (across George Bush from Duncan Field), our main gathering space looks out over an ugly parking lot. I'd like to plant some kind of hedge or bush near the parking lot to hide that view, but also to help create a small courtyard area in the grassy space between our doors and the parking lot. Ideally, I'd like something fast growing, hearty, and low-maintenance. We would hope to plant some flowers or something else with some color on the inside of these hedges, again to help create the courtyard space. What do you suggest?
