September 7, 2011Q.Hibiscus Leaves
I have recently planted three beautiful Hibiscus plants in my garden. I live in San Diego where the weather is favorable. The downside - the leaves have begun to be attacked by something - leaving holes in the middle of the leaf of the plant. Please advise what it is - and how can I treat it.

Certified ExpertA.There are a couple of different pests that it could be. If you are not seeing any bugs, I would lean towards it being slugs. They come out at night and can be difficult to spot due to this. A pan of beer placed near the base of the plant overnight will confirm whether this is the problem or not.
If it is not slugs, there are several possibilities. It could be flea beetles, Japanese beetles or caterpillars.

September 10, 2011Q.Perennial Hardy Hibiscus
I would like to know if I should cut down the stems of my hardy Hibiscus after blooms are spent and fallen. The leaves are mostly browning, but I am not sure if the stems are required for the plant to nourish itself for regrowth in the spring. These hibiscus totally die off in the winter (Erie, PA).

Certified ExpertA.Depending on your climate, hardy hibiscus can be left in the ground throughout winter. In cooler climates additional protection may be needed, such as tarps, burlap, etc. A light trim is ok but I would wait until spring before performing any worthwhile pruning.

September 13, 2011Q.Hibiscus Plants In Colorado Winter
I have 3 hibiscus plants, 2 smaller ones and one about 4 foot tall. We live in Colorado. Do we need to bring them in the house for the winter or will they survive?

Certified ExpertA.If they are in pots, this would certainly make it easier, as you can place them either indoors or in a protected area. For those planted in the ground, mulch and winter wrapping of hardy varieties may be enough.

September 14, 2011Q.Hibiscus Blooms
I planted a hibiscus plant about 2 months ago. It gets lots of buds on it but when it starts to bloom, the flower just partially comes out and then the next day, the bloom falls off the plant. The flower never does completely open up. Any idea what I am doing wrong to cause this?
