1. Watering

Water your purple azalea regularly, especially during the hot summer months. However, be careful not to over-water, as this can cause root rot.

Purple Azalea Planting Tips

For the best results, follow these planting tips when growing your purple azaleas.

1. Soil Preparation

Prepare the planting site by loosening the soil to a depth of about 12 inches and amend with organic matter like compost or peat moss to lower the pH levels to at least 5.0 to 6.0 range.

2. Location and Sunlight

Plant your purple azalea in a location that receives partial shade to protect it from hot afternoon sun and to keep the soil moist. Azaleas planted in full shade may become leggy while azaleas exposed to full sun may suffer from leaf scorch.

3. Mulching

Mulch around the base of your purple azaleas to help retain moisture and prevent weeds from growing. Ensure that they are not piled high against the trunk as this can cause stem rot and make sure to avoid contact with the crown.
