Dwarf witch-alder

Year-round

Dwarf fothergilla is a small shrub that lights up with white bottlebrush blooms in spring and then puts on one of the best fall color shows of any small shrub, in yellows, oranges and reds. It wants consistently moist, well drained, acidic soil and does best with at least a half day of sun.

• Give it full sun to light shade. More sun generally means more flowers and brighter fall color.
• Keep the soil moist and acidic. It struggles in soil that dries out or that has lime in it.
• It stays small, usually two to three feet tall and wide, so it fits well near a foundation, walkway, or as a low border shrub.
• According to the Lady Bird Johnson Wildflower Center, this species naturally grows in parts of the coastal Southeast, including Georgia.
• It holds up well against most pests and diseases when it has the moisture and soil it wants.

Fall

Fall is the payoff season, when dwarf fothergilla turns shades of yellow, orange and red, often all on the same shrub.

• Color usually peaks around November in the Atlanta area, and it varies year to year with sun, rainfall and temperature, per Clemson Extension.
• No pruning now. Cutting back in fall removes flower buds that are already set for next spring.
• Rake up fallen leaves under the shrub to reduce leaf spot disease carrying over into next year.
• Check that the soil is still moist and acidic heading into winter, since fall dryness can stress the roots.

Raking fallen leaves promptly keeps the bed looking maintained for street view, especially if a fall yard check is expected.

Winter

Dwarf fothergilla has little winter work. Once the leaves drop, its zig zag branches are the main show.

• Leave the bare branches alone. Their naturally crooked, zig zag pattern is a winter interest feature, not something to prune away.
• Do not prune now. Wait until right after next spring's bloom so you do not cut off flower buds.
• Refresh mulch over the root zone to buffer freeze thaw swings and keep the soil acidic.
• Check that the bed drains well. Soggy winter soil combined with cold is harder on this shrub than cold alone.

A fresh mulch ring each winter is the one tidy up move that keeps a leafless, dormant shrub still looking intentional from the street.

Spring

Spring is when dwarf fothergilla puts on its show, with white bottlebrush flowers opening on bare stems before the leaves come out.

• Expect blooms roughly February through April in the Atlanta area, per the Lady Bird Johnson Wildflower Center.
• Feed it twice this season with an acid forming fertilizer, once in early April and again in mid May, per Clemson Extension.
• If you need to prune, do it right after the flowers fade. Pruning any later removes next year's flower buds.
• Keep any pruning light. This shrub has a naturally attractive rounded shape and does not want to be sheared hard.

For a tidy street facing planting, finish any shaping within a week or two of bloom fade rather than later in the season.

Summer

Summer care for dwarf fothergilla in the Atlanta area is mostly about keeping the roots consistently moist through hot, humid stretches.

• Water deeply during dry spells. This plant does not like to dry out, especially if it is in full sun.
• If it is in full sun with no supplemental watering, afternoon shade helps it get through the hottest weeks, per Clemson Extension.
• Water at the soil line in the morning rather than overhead. Wet leaves overnight invite leaf spot disease in a humid climate.
• A layer of mulch over the root zone helps hold moisture and keeps the soil acidic.
