Gardenia Plant Pests?

My gardenia plant has a white, powdery substance around the buds, which are not blooming and subsequently dropping off. Leaves are green and shiny and new leaves are appearing. Some leaves have holes in them. What to do?

ANSWERS

The plant sounds like it may have a bit of powdery mildew and possibly flea beetles. Here is information both these things:

We recommend treating the plant with neem oil. It is safe for humans and pets and treats both problems your gardenia possibly has. Here is more information: http://www.gardeningknowhow.com/plant-problems/pests/pesticides/neem-oil-uses.htm

You will not be able to make the whole plant regrow its root. They just would not have the energy for it. But, you can try taking the plant and using it for cuttings to make new gardenia plants for your yard. This article will help:

Freeze Tolerance

I have two established gardenia bushes on the south side of my house and they have been doing well for eight years. Tonight the temperature is supposed to drop to 20. Do I need to cover or mulch them?

Gardenia Plants

I have two Gardenia potted plants in a screened in area in Florida. I believe it is infested with mealy bugs – little white, straight masses of them on the leaves. What is a good remedy?

Pruning a Gardenia

Can you prune a gardenia now, and can you cut the limbs and make a sprout where it will come up at another place? We live in Newnan, GA. and the shrub has become really bushy.

ANSWERS

You can prune now, but you will reduce the number of blooms you get on the plant in the coming year. It is recommended that you wait until after it blooms to prune so that you do not lose the flowers.

You can take cuttings from the pruned branches. This article will help with that:

White Soft Stuff on Gardenia Plant

This stuff is on my gardenia plant. Most of the white cotton stuff is on the stems and heavier on joined branches. I have sprayed a fungicide last week and it seems to be more of that stuff. I used a cotton tip to soak the white stuff and removed it, so I thought. I think it is also in the soil. Sometimes I see a small bug flying around.

ANSWERS

That is typical of mealy bugs. They just look like white fuzz. They cluster together and can look like large and small clumps of cotton.

Sick Gardenia Bush

My gardenia bush held on beautifully and had lots of blooms during the spring and summer, but we had some below freezing temps and now the leaves are brown and crispy, even though I covered it during the extreme cold. Is is a goner or will it come back?

ANSWERS
Nikki

I am sorry to hear about your plant. It may come back. It depends on how badly damaged it was. This article will help: http://www.gardeningknowhow.com/plant-problems/environmental/tips-for-saving-cold-damaged-plants.htm

I volunteer at a nursing home and one of the Residents was given a Gardenia which was not watered for weeks and was in a similar condition to yours. I moved it to my shadehouse, pruned it severely and soaked it in a weak liquid seaweed manure brew for a week. After 6 weeks It now has new leaves and I will replace the potting mix after the first flower falls. I did not replace the soil immediately as this would have stressed the plant even more. The cure is L.S T.L C. (long slow tender loving care).
Good luck
