Too Much Rain

Three weeks ago I planted new shrubs (barberry) in my yard and we have had nothing but rain ever since. The ground is completely saturated and puddling. At first, my bushes were looking great, but now they are looking very bad. I read on a gardening site about poking holes with a pitchfork around the bushes to aerate the soil, which my husband did last night, but is there anything else I can do to save my bushes from too much water?

Consider placing a berm in your landscape to redirect water to another area and improve drainage. These article should also help:

I have two barberry scrubs and have had them for six years, I put peat moss in my soil every year and every second year I add black dirt and peat moss, last year we had an abundance of rain and they did okay. You could also try putting bark chips around them or some kind of mulch

Berberis With Mildew

Moved into house 12 months ago. Berberis shrub (barberry) in front garden had mildew. Cut it back in autumn, shooted well, but mildew is back. What to do? Type unknown, but common. No other mildew in garden.

In addition to cutting off the affected foliage, try treating the shrub with neem oil. It's an effective fungicide as well as pesticide. Here is more information: http://www.gardeningknowhow.com/plant-problems/pests/pesticides/neem-oil-uses.htm

How and When Do You Prune Berberis

How and when do you prune berberis?

ANSWERS

You should prune it either in late winter or directly after it flowers.

If it is just a shrub, you can just prune to shape. It has no real need to be pruned for health reason. Just remove any branches that are outside the shape you want with a sharp pair of shears. If it is a hedge, then prune to retain the proper hedge form.

How Do I Control Insects Eating My Barberry Shrubs?

I have 3 shrubs, one facing south planted 2 years ago and 2 facing east planted 1 year ago. I had hoped the insect infecting the older shrub wouldn’t repeat again this season but it did and it also claimed the foliage on the 2 newer ones. My neighbor across the street has several beautiful thriving shrubs, mine look near death, what can I use to treat them with?

ANSWERS

Are you certain it's a pest. Depending on the symptoms, it could be a fungus attacking the shrubs, which would also explain the spreading. Treat the plants with neem oil, which should take care of both pests and fungal issues. Here is more information: http://www.gardeningknowhow.com/plant-problems/pests/pesticides/neem-oil-uses.htm

Is Daybreak Barberry Affected by Wilt?

There are a lot of red cedar trees around here which makes it almost impossible to grow most barberries.

ANSWERS

Although I've not seen disease on barberry plants, given the proper conditions, almost any plant can be affected by pathogens. The following link provides information on rusts on barberry: http://www.aphis.usda.gov/plant_health/plant_pest_info/barberry/

What Makes Small White Cocoons & Squishes Red?

The cocoons are sticky & bug inside squishes red. They are all over the branches of barberry bushes and Japanese maple.

ANSWERS

The "cocoons" are likely the bug itself. It sounds like you have either mealy bugs or wooly aphids. Here is more information about how to control both pests:

Newly Planted Japanese Barberry Shrubs Fading and Leaves Drying Up

Why are my newly planted Japanese Barberry shrubs fading and the bronze leaves drying up? I live in north Texas. It was 90 for two days and humid. They are planted in a well drained bed in part shade and full sun. Could the plants have a disease? Or a bug eating the leaves? I have not seen any. Please tell me how to care for them. I love these plants.

ANSWERS
theficuswrangler

It sounds as though the plants are drying up. This is a good article with general information on planting bushes: http://aggie-horticulture.tamu.edu/earthkind/landscape/planting-a-tree/
If you think this might be the problem, you can dig up the bushes to rework the roots, then try to replant them.
If none of this sounds applicable, it is possible that you were sold diseased plants, and you should dig them up and return them to the seller. You should get new plants, or a refund. In case of disease, don't put new plants in exactly the same spots.
You can also take samples of the dying leaves to an Extension Service for analysis. This link will help you locate one: http://www.gardeningknowhow.com/extension-search/
