Q. Chewed Leaves

We have two gardenias in self-watering pots in a lightly shaded position, as they suffered in direct sunlight. The leaves on both plants have been badly chewed, many to the point of no leaf remaining. Have not yet detected the grubs responsible. Please advise on what action to take. There are about six buds ready to flower on one and none on the second. Leaf color is a healthy green and flowers seem okay.

I would suspect that it is slugs. They tend to creep in at night, chew up leaves and be gone by morning. To test to see if it is slugs, leave a pan of beer nearby overnight. If it is slugs, you will find a few in the beer in the morning.

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: https://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:

Q. Gardenia Dying

I live in San Diego and my indoor gardenia plant has lost all its leaves. I think it happened when the heat wave hit and now it’s too cold. What are we supposed to do when these things happen? I don’t have a temperature set area for the plant to stay in.

Times like this can be difficult for gardenias. For the heat, I would make extra sure that the plant is watered well. Check it twice a day.

When it gets too cold, cover it at night with a sheet or light blanket and make sure to take it off first thing in the morning. The covering will help hold in heat and keep away any possible frost that may occur. It is not foolproof, but it will help.

In the meantime, as long as the stems and branches are still alive, the plant can regrow the leaves. Cut back fertilizing until the leaves return, but make sure that every thing else in terms of water and light are provided.

Q. 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.

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:
