I planted some boxwoods in the fall and they looked healthy for about the first two and a half months. The leaves have now gone to a red green color. I was wondering if it had something to do with the weather or my soil. I live in Alabama. They are getting plenty of sunlight.
This is something that happens to boxwoods when they are stressed. Given the cold weather in the South this year, I would guess that the weather is to blame. It should correct itself when the weather warms up.
I have a Buxus which is in a chimney pot and has been for 8 years. It has now split the chimney pot, so I need to repot it. When I removed it from the pot, I discovered that it had a very long root 'ball', approximately 18 inches. I want to repot it in to a 'normal' type pot. If I sever the root ball by approximately half to do this, will I kill the shrub?
I would not take 1/2. A 1/3 would be ok and should not harm the plant much. These articles may be helpful:

It's cool still mid 40's at night and mid 50's as highs during daytime in north/western Frederick County, Maryland. When is the optimum time to spray dormant oil on major infestation of scale on boxwoods and Leuken Laurels?
Eggs are laid in late April and a new batch of this pest hatches in about 3 weeks. This is the time when treatment is most effective. Mature scale bugs wear shields, but the nymphs haven’t had time to develop them.
I would recommend neem oil spray. It is organic, but we have found it to be highly effective against scale and other sucking bugs. Here is more information: https://www.gardeningknowhow.com/plant-problems/pests/pesticides/neem-oil-uses.htm
How do I identify the variety of boxwood that is in my yard?
This article has a listing of the different varieties that should help you with identifying what you have: http://www.backyard-landscape-ideas.com/boxwood-shrubs.html
My buxus plant has continually yellow leaves all over. My new one has also began to get yellow leaves. The first one is quite bad. They are both potted.
There are three things that might be causing your buxus problem. Nutrient deficiency (nitrogen is the most likely culprit), lack of water (is it in a sheltered spot that might not get the rain it should?), or a fungus. If the latter, you must treat with a fungicide and clean away all those dropped leaves.
My beautiful fifty-year-old American boxwood hedge was liberally sprayed yesterday with wasp and hornet killer by a worker in my yard. I immediately drenched the affected eight-foot area with water, called a garden shop and they told me they knew of no 'antidote', and to expect the worst. What should I do now, and what damage should I expect? I poured gallons and gallons of water on the boxwoods and read the spray can label. It warned of possible damage to evergreens, but I noted that the label stated that it left no oily residue. Does this mean that water may have removed the spray from the foliage?
I think that you did the best thing that you could by spraying the plant down with water. This will have diluted the spray. You can try spraying it down again to wash away any residual, but I think that what is done is done. Chances are, the plant should pull through fine, but if there is damage, you will see yellowing leaves that will eventually fall off.
How do I root boxwood?
Boxwood are fairly easy to propagate from cuttings. Please see this article for more detailed information:
