The care they receive now and this fall will influence flower quality next year. Seed pods should be removed immediately to assure a quality crop of flowers next year. I suggest that the flower clusters be removed just as the petals begin to fade. This prevents seed pod development, and reduces the chances of disease starting on the dead flower petals. Azaleas and rhododendrons are shallow rooted and benefit from a two-inch layer of mulch to conserve valuable moisture, reduce winter injury, and prevent root damage caused by cultivation.
Coarse materials are best for mulching.
They allow the soil to breath and do not restrict movement of rain or irrigation water. Oak shavings, hardwood chips, aged sawdust, or shredded tree bark are good. Keep all mulch material away from the stem of the plant. The bark is easily rotted by the added moisture retained in the mulch. During the winter months, some mulch against the stem is suggested as being helpful in reducing winter injury to the crown of the plant.
