Most plants aren't going to do well at pH 4.3. That's one nice thing about blueberries, not many weeds.

Lingonberry may do well as a ground cover.They can take cold and need that low pH. Brady

Our blueberry shrubs are typically surrounded by creeping charlie, Asiatic dayflower, and the occasional butterflyweed. These plants seem to tolerate the acidic soil. But I regard them as weeds, and they get pulled and composted several times a year.

Creeping Charlie in the compost? I have always heard that CC as well as Chick weed should not go there as it will sprout and spread when you use the compost. Many times you cannot get the temperature high enough to kill these roots.

Some claim that a ground cover is good as it shades/cools the roots while others claim that ground covers rob moisture from the soil and therefore from the bushes.

I wonder what I might do to control weeds and at the same time have more real estate to expand my flower gardens.

Planting flowers around your blueberry shrubs is a judgement call. It won't kill the shrub, but the flowers will compete for moisture. If you are mindful of drought conditions, and keep the shrub watered, the shrub should do OK. If you are looking for maximum growth and maximum fruit production, then the shrub should be kept free of weeds, and heavily mulched with wood chips, shredded leaves, or something similar.

I planted strawberries around mine. I have to keep them away, but it has worked out good for me.

Wintergreen or cranberries both are tolerant of low pH and both do fine in soil with average moisture.

I thought of wintergreen, but it's a plant that likes partial sun, it would not do well with my blueberries in full sun.

There are many "wild" low blueberries that grow no more than 12-18 inches tall and some are spreading types.

Many are found in Maine.

Two that I remember are...

Look up 1) Vaccinium angustifolium, 2) "Brunswick Maine Blueberry" (available at Raintree Nursery) grows one foot tall and spreads to five feet.

Looks like a perfect match and they bear their own fruit too.

I am sure there are more ...
