Agapanthus is at its best in July and August. The tall flower stems of this beautiful summer-blooming relative of the amaryllis rise above strappy green foliage and open into rounded clusters of trumpet-shaped blooms. July is the perfect time to keep these plants looking their best, and to make sure they have everything they need to continue performing well through the rest of the season.
Although agapanthus is generally considered an easy-care perennial in USDA Zones 8-11, a little midsummer care can make a difference to flowering and overall plant health. The key is to avoid overdoing it. Too much fertilizer, too little sunlight, poor drainage, and inconsistent watering can all affect how well these sun-loving plants perform.
