I have a rose (Serenity) that I purchased from heirloom roses.com which is keep on my balcony in partial shade. I received the plant on 8/7/15. It is approximately 16 inches high. Two branches have newer growth and each of these two branches ends in a bud. The buds have not opened. I hadn't watered in several days and the soil was dry at least an inch down. As I was watering the plant, several very small bugs that looked like tiny flies flew off the plan. They were very small and the color was difficult to determine. Perhaps they were a very light brown. I kept shaking the plant and they continued to fly off. We then had a short, severe downpour of rain. When I went back outside and shook the plan, there were no more bugs flying off. Any idea what they could be? Should I be concerned?

The insects that flew away had nothing to do with the unopened buds. There is one tiny insect, thrips, which can damage buds, but it does not fly. http://extension.umd.edu/hgic/thrips-flowers So, that is not a problem.

We suggest you be careful about underwatering. Do not let the soil dry down more than 1/2" while these plants are so new and getting their root systems established.

Otherwise, we do not think you need to be concerned. Realize that containers get very hot when temperatures are high. Their roots get much hotter than those of plants with roots in ground soil. This can affect growth.

Here is info on veggie container gardening, some of which may be helpful to you: http://extension.umd.edu/sites/default/files/_images/programs/hgic/Publications/HG600%20Container%20...
