Planting & Care
1. Planting: First, select an area with well-drained soil and full to partial sun (4 to 8 hours of sunlight per day). When you're ready to plant, dig a hole that's twice the width of your plant's root ball and just as deep. Then, place your shrub, backfill the soil and water to settle the roots. Finally, mulch the surrounding soil to conserve moisture.
2. Watering: Water your Althea Shrub once or twice weekly in order to conserve soil moisture. If you're not sure when to water your shrub, check the soil with your index finger, about 3 inches down. If the soil is dry here, it's time to water.
3. Fertilizing: Fertilize before new growth begins in the spring with a well-balanced blend, such as 10-10-10.
4. Pruning: Prune your Rose of Sharon in the winter, after flowering, in order to shape your shrub.
