#ProPlantTips for Care:

Red Heart is easy to grow and has no serious insect or disease problems. Althea is adaptable to a wide range of soil conditions and tolerant of full sun all day! Rose of Sharon does need well-drained soil but is not particular on the type and even doing well in poor soils. If drainage is an issue, add extra dirt in a raised bed if you need to improve drainage. Give them a regular schedule of medium water, especially when they are young plants. Apply a slow-release fertilizer designed for flowering plants at the same time. Follow application rates on the label.

Add a thick layer of arborist mulch in containers and in-ground plants alike. You'll cut down on surface evaporation with this useful garden must-have, plus provide much-needed insulation from heat and cold. Deadhead your shrub after flowers fade to remove seedheads before they mature to prevent self-seeding. Annually pruning in late winter or early spring will result in increased shoot vigor and larger flowers. Renewal prune every 3-5 years to maintain vigor.
