Ivy geraniums are favorite annuals for flower pots and window boxes. Their trailing habit and long-lasting flowers beautify patios and hanging baskets all summer long. Sometimes, an ivy geranium requires special care when it stops blooming.
Like all zonal geraniums (Pelargonium spp.), ivy geranium is easy to grow. It requires light, moist, well-drained soil. Full sun and regular fertilization help it grow and bloom its best.
After a geranium blooms and sets seed, it naturally stops blooming. Deadheading spent blooms triggers a hormonal response for reblooming and makes room for new growth. Often, failure to bloom is caused by falling behind on deadheading.
Ivy geranium can fail to bloom because of poor nutrition. Nutrients drain quickly out of containers and need to be replenished regularly. If your geranium is floundering, cut it back by half and resume regular applications of a balanced (10-10-10, for instance) plant fertilizer.
