Description and Cultural Plant Tips

Crape myrtle is one of the toughest, most adaptable and showiest plants that we have in the Bay area. It can be grown as a shrub or tree. Either way it has 6 -12inch long clusters of flowers and a highly ornamental trunk that exfoliates when young to reveal a smooth, lightly mottled look. It thrives on heat and can be used as a specimen or  potted plant, against walls or fences, as a screen or informal hedge.

Plant slightly above grade in a sunny location. Do not disturb the rootball. Fertlize with a slow release fertilizer. Water well and mulch in a 2 -3 food circle around plant. Do not overfertilize as this tends to produce lush foliage at the expense of flowers. Water deeply once a month when established. Do not water leaves as this plant is susceptible to powdery mildew and leaf spot. Foliage may turn yellow if the soil is too alkaline. Prune in late winter. New growth can be pinched at tip to increase branching and flower numbers. Removal of seed pods cause a second flush of flowers.

Susceptible to powdery mildew and fungal leaf spot. Aphids may also infect new growth and cause sooty mold. New varieties are available that are resistant to powdery mildew.
