My Bee Balm leaves are yellow. Could it be due to all the rain we had this spring?

Why do my begonia plants die every winter? I keep them in containers and move them indoors when cold weather sets in. Should I set them in a sunny location?

Syringa vulgaris

Lagerstroemia indica

I’m looking for a dahlia variety that will grow well in the South.  I live in Waco, TX and I’ve tried planting them in numerous locations, but the plants and tubers never make it through summer.

Every year my dahlias bloom in early autumn and only have a few flowers. Why do they always bloom right before frost? What should I do differently? 

Allium sphaerocephalon

Phlox paniculata

Allium senescens var. glaucum

Gladiolus x hortulanus

Are there any good homemade remedies for controlling bugs and diseases on roses?

I have a honeysuckle bush with powdery mildew. It is in full sun. What do I do? It was like this last year also.

My garden consists of a balcony on the north side with a little bit of eastern exposure with a little morning sun. I've had so much trouble with bugs and mildew. I've been dumping plants all summer and buying new ones. Even begonias and impatiens didn't do well. First it was aphids, then mildew, then white flies. I did so much spraying with all kinds of things including insecticide. The bugs finally seem to be gone but the plants look terrible.  The leaves have white stuff on them and some have black.

I have a Center Glow ninebark bush that is going into its second year. It developed powdery mildew on some of the leaves. It was originally located on the south side of the house next to a retaining wall. I have since moved it more into the open. Is this enough to control the problem?

Lilium species

I am having a problem with my palm tree.  It has developed a white powdery substance on 50 percent of the leaves.

My phlox are covered with this white stuff and the leaves are starting to turn yellow and brown. What should I do?

Every summer I take my poinsettias outside.  Within 2-3 weeks of bringing them indoors for winter a white powder appears on the leaves. I am able to get them to bloom but the leaves eventually yellow and drop off.

Last summer many of my plants and shrubs were attacked by powdery mildew.  We have pets and do not want to use chemicals.

I heard you could use baking soda to control powdery mildew.  Is this true?  If so, do you have the recommended rate?

My phlox and monarda develop powdery mildew each year. The leaves yellow, curl and brown. What can I do?

My garden plants were covered with powdery mildew this summer. Can I spray something on them this fall to prevent problems next year?

When is the best time to prune potentilla, forsythia and spirea?

This spring I planted two silver lace vines in two different locations on the south side of my house.  Both plants wilted, turned yellow and died.  Do you have any suggestions for a replacement?
