Q. Planting and Care of Japonica Pieris

What type of protection from sun, water, and wind does this bush need?

Japanese andromeda prefers a moist, well-draining, organic and slightly acidic soil. It prefers partial shade but will tolerate full sun (may require additional watering in these areas, however, to keep soil moist and cool). You will want to avoid harsh, windy areas too, so look for a sheltered location if wind is a factor.

Q. Bleaching of Green Leaves

I have small andromedeas and azaleas at the bottom of slope along a stone wall. They were planted two or three years ago. The plants have leafed out this year as though they were bleached. What do I need to add to the soil? Thanks.

It sounds like it may be azalea lace bug. This article will help: https://www.gardeningknowhow.com/ornamental/shrubs/azalea/azalea-lace-bug.htm If there are no signs of lace bug, then it could also be azalea gall. This disease commonly occurs in early spring on new leaf growth. The leaves become curled, fleshy, and pale green to white. Affected leaves eventually turn brown and should be removed and destroyed. However, it is most likely attributed to lace bugs, as they generally cause bleaching of the leaves.

Q. Pieris Tree

We bought a 40 year old house that has a pieris tree in the backyard. The flowering tree is about 10 ft. tall. However, the flower bed it is in is about 2 ft’ wide, so most of the roots are under the grass. The soil underneath the tree is loaded with beetles and other insects and the tree itself has become weakened with many areas on it that are losing the leaves and flowers. Shall I take the sod off or will I damage the existing root system? In your opinion, what might I do to save this tree?

Have you noticed any insects on the tree itself? Any insect holes on the trunk/branches or signs of insect damage on the foliage? It will become clearer what to do after looking under that sod. A closer examination, and identification, of these insects should be your first priority. There are a host of insects that could be damaging to your tree, such as the black vine weevil which attacks root systems and may be the cause for the weakened state of your tree. If your insect issue is not addressed, the tree will likely continue its decline.

Q. adromeda bush

last year my andromeda bush was suffering so I sprayed it with neem oil and I cut it back. This spring it looked to be healthy again, with lots of bright green leaves. But after a week-long business trip, I returned home to find some brown leaves, some drooping leaves with small rectangular white growths on the underside of two leaves. I held some white paper underneath and shook the whole bush but none of the specks moved so I don’t think the problem is spider mites. Nonetheless, the bush is clearly suffering again and I fear it will die, despite its resurgence just a couple weeks ago. Can anyone help? Thank you.

Andromeda likes soil to be on the damp side.
Slightly moist all the time.
Did the plant dry out while you were away?
The wilting and browning leaves may be a sign of needing more water.
White growths on the leaves may be Mealybugs.
I would again treat with Neem Oil.

Q. andromeda (small size – grows to about 5 feet)

It was moved twice as a result of construction in its area. Now it has only sparse new growth on it. I was wondering if it might help if we cut it down at end of season. I’m not ready to give up on it yet.

Do little to the plant except make sure it is watered well.
Keep the soil moist while it settles into it's new location.
2 to 3 inches of hardwood mulch will help it retain it's moisture.

In the spring you can clean up any dead plant material and fertilize it.
Here is a link to refresh you on the care.
Good luck.

Q. Mountain Fire Andromeda

I have had a Mountain Fire Andromeda for a few years now and would like to know if I can or should cut off the once white flower balls which are now brown and really take away from this beautiful bush. They don’t seem to just fall off on their own. If I can, about how far down the branch should I go? Thanks very much for your help!

Yes, you can cut off the flowers after they have faded. You can cut the entire raceme (the portion of the branch where the flowers were) but don't cut off the part with the leaves.

Q. Orange Andromeda flowers

Every year my Andromeda flowers bloom white. This year they bloomed white but a day or two later they all turned orange. Does cold weather cause this to happen?

I have not been able to determine a reason for the color change on your plant.
Too much sunlight, cold temperatures even reverting if you shrub is a Hybrid are possibilities.
