I purchased a few Rudy Haag burning bushes here. They arrived well and healthy-looking. I took care of them as instructed and for the first 3-4 weeks they did really well but after that they started deteriorating. New leaves would appear but quickly shrivel up and die. Leaves and branches would just get dry and die (even with regular watering).
When I contacted the farm I purchase these from, the horticulturist told me he didn't know what was happening and recommended me to move mulch away from the bushes and use less water. Well that didn't help.
I put two of them in plastic pots and brought them inside. One looks already dead and one still has some life. I did notice some spider mites under a leaf of the semi-healthy one (I think they're spider mites), but not too bad. I removed them and bought an organic herbicide at Lowe's that claims to kill over 100 common plant insects.
Question #1 - What can I do to save these plants if not too late?
This morning I noticed some very tiny objects doing parabolic jumps on the dirt. I have no idea what these are. Tried using a magnifying glass and still too small to tell.
Question #2 - What are those? If you look closely, you'll see what I mean in the video below. At first, I thought they were tiny specs falling from the bush, but no, they're tiny things hopping around the bush. I only see them in the pot with the semi-healthy bush, not the other one.
