Grow Bright Azaleas

A lazier shrub per exciting blossom I have yet to find.
Azalea

How do you tell an Azalea from a Rhododendron? Most Azaleas have only 5 or 6 stamen while most rhododendrons have 10 stamen. Azalea leaves tend to be thinner, softer and more pointed than rhododendron leaves.
In a subjective way I think Azaleas produce more flower cover per plant.

Tips for Growing Azaleas

  • Azaleas are relatively pest-free  and easy to grow plants but may need a fungal spray if leaves are attacked in spring.
  • Azaleas like some shade  but deciduous varieties do well in full sun. Sun can produce more compact plants with more blooms but not as long lasting.

  • Azalea like a slightly acid soil such as that found under oak and pine trees. A mulch of pine bark,  needles or wood chips helps to keep moisture in the ground and suppress weeds.
  • Azaleas do not like “wet feet” but need moisture too help to produce more flower buds for next year. So give plants a good soaking everynow and then after flowering.
  • Good drainage can be provided by planting Azaleas with the tops of their root balls a few inches above ground level and mounding the soil up to the plants. Do not plant too deep.
  • Established Azaleas do not need fertilizer that only encourages unproductive lush growth.
  • Avoid pruning but shorten long slender stems with no side shoots and cut out dead wood  at any time.

If I were to choose one variety of Azalea it would come from the Knaphill hybrids of the 1960’s. They are well worth seeking out.
