Description

Hardy Hibiscus 'Luna Red' Characteristics

'Luna Red' are beautiful additions to landscapes with suitable growing conditions. Humidity will not bother 'Luna Red' and regular deep watering is recommended in medium moisture soils. Though the plant can survive in part shade, full sun is needed for the best flowering and strongest stems. Good air circulation can help to prevent molds and mildews. Strong winds can cause wind damage. The plants may become leggy if the stems are not pinched back every 8 and 12 inches. Before winter sets in, cut the whole plant back to 4 inches above the ground to allow for new growth in spring. Regular deadheading of spent flowers can improve the overall appearance of the plant. Occasional fertilization can improve low fertility soils.

Leaf spot, rusts, blights, and canker may affect 'Luna Red'. If untreated, Japanese beetle infestations can cause severe damage to the foliage. Leaf scorch occurs in dry soils.
