How do I root boxwood?
Boxwood are fairly easy to propagate from cuttings. Please see this article for more detailed information:
Will Buxus sempervirens grow in Nigeria, a tropical climate, and can the same be grown from seeds?
Unfortunately, it will be a bit too warm where you live to grow this plant. It is meant for temperate zones and needs a dormant period each year, which tropical climates cannot provide.
Will be transplanting boxwoods from BB to containers. What type of soil is recommended?
They generally prefer well-draining, organic-enriched soil but are quite adaptable to various soil types, as long as it drains well. This article will help with growing this shrub: https://www.gardeningknowhow.com/ornamental/shrubs/boxwood/boxwood-care.htm
How do I get rid of wasps in an ornamental boxwood bush?
I am assuming that these have a nest in the bush. If this is the case, you can use a bag to cover the nest and then cut the nest off the plant. It is best to do this in the very early morning, when wasps are least active and wear long sleeves and long pants, just in case.
After the nest is removed from the plant, you can either fill the bag with wasp killer or WD-40. That will kill them in the bag.
I would like to trim/shape my boxwood hedges soon (September). I live in Kansas City, MO. Is it safe to trim them now? Not a hard trim but to really give them a formal look.
Pruning encourages new soft growth that is susceptible to frost damage, so hold off trimming your boxwoods till late spring if you plan to do hard pruning; light tip pruning, however, can be done any time.
I planted English boxwood when they were 8 inches tall to border a small rose garden. They are now almost 2 feet high and around, and form a solid border. I need to prune them to a better shape and neaten them. The border is square shaped, formal, with a raised urn in the center and four short paths from each side to the center, roses in the four corners. I think I want the four corner shrubs a little taller and maybe pyramidal. When should I prune, and how much can be done at one time?
The best time to prune your English Boxwoods is when they are dormant. So once they have gone dormant prune them to the shape you desire but try to shape them with the least pruning possible at any one time. Once you see how the following seasons growth goes, it is easy to see how much more pruning is needed and where. Going slowly allows you to get the look you want and less effect to the overall performance of the plants.

I have these bushes that turn into trees that look exactly like Boxwood. They are taking over some of the place I want to open my yard, which I can't do until I kill them out. So please, how do you kill them? Please email me the answer. Thank you so much!!!
Cut them down and then paint the fresh, open cut with undiluted Round Up. This will kill the plant to the roots so that they can't grow back.
