Scaevola requires adequate water and fertilizer. It must be grown free of drought. It will tolerate 10 to 15 days of rainy weather, but full sun and heat without moisture will cause it to decline fast. Rain and humidity don't bother Scaevola. It prefers moist, well-drained soils high in organic matter.
Full sun is best.
Plants grown in partial shade may grow leggy and bloom poorly. Be careful not to crowd New Blue Wonder. One plant can spread three to four feet by September. For best results, plant it on 18-inch centers. It responds to fertilizer by putting on vegetative growth.
