Please note: Images on our website depict plants and trees at full maturity to showcase their expected grown characteristics. These images are illustrative examples only and do not represent the size of plants or trees upon delivery.

Pruning: Minimal pruning is required. Light pruning can be performed after the flowering periods to shape the plant and encourage denser growth.

Fertilization: Fertilize with an azalea-specific fertilizer after the first bloom cycle in spring to promote growth and support vibrant blooming.

Winter Protection: In the colder zones, apply a layer of mulch around the base to protect the roots from freezing temperatures.


Select a site with partial sun to partial shade and well-draining, acidic soil. Dig a hole as deep and twice as wide as the root ball. Carefully place the azalea in the hole, ensuring the top of the root ball is level with the ground surface. Backfill with soil, water thoroughly, and apply a layer of organic mulch to conserve moisture and suppress weed growth. Space plants approximately 3-4 feet apart to allow for their mature spread.

Water regularly to maintain evenly moist soil, especially during dry spells and in the heat of summer. Consistent moisture is crucial to support the plant's flowering cycles and overall health. Best performance is achieved in partial sun to partial shade, with morning sunlight and protection from harsh afternoon rays. This moderate exposure is key to promoting vibrant blooms while maintaining the health of the plant.

These characteristics make them popular choices for landscape designers and homeowners looking to add color and interest to their gardens throughout the year.

The best time to plant azaleas is typically in the early spring or fall. Here's why:

Spring Planting: Planting azaleas in early spring, just after the last frost date in your area, allows them to establish their root systems before the onset of hot summer weather. This timing gives the plants time to settle in and become established before the stress of summer heat and drought.

The cooler temperatures and increased moisture levels in the soil during the fall months help promote healthy root growth without the stress of summer heat.

Regardless of whether you choose to plant in spring or fall, there are a few key considerations to keep in mind:

- Avoid planting during periods of extreme heat or drought, as this can stress newly planted azaleas.
- Prepare the planting site beforehand by amending the soil with organic matter, such as compost or peat moss, to improve soil structure and fertility.
- Plant azaleas at the same depth they were growing in their nursery containers and space them according to their mature size.
- Water newly planted azaleas thoroughly after planting and provide regular watering as needed to keep the soil evenly moist, especially during the establishment period.

By planting azaleas in early spring or fall and providing proper care and maintenance, you can help ensure their successful establishment and long-term health in your landscape.

When planting Autumn Lilac Azaleas, spacing is essential to ensure proper growth and a visually appealing arrangement. Here are some general guidelines for spacing Autumn Lilac Azaleas:

Single Specimen Planting: If you're planting Autumn Lilac Azaleas as standalone specimens or focal points, space them approximately 2 to 4 feet apart. This spacing allows each plant to develop a full, balanced canopy without overcrowding, ensuring adequate air circulation and room for growth.

Mass Planting or Border: For creating a mass planting or border using Autumn Lilac Azaleas, space the plants about 2 to 3 feet apart. This closer spacing creates a dense, lush effect and allows the plants to fill in the space more quickly, resulting in a stunning display of color and texture.

Consider Mature Size: Keep in mind the mature size of Autumn Lilac Azaleas when determining spacing. These azaleas typically reach a height and spread of about 3 to 4 feet, so spacing them accordingly ensures they have ample room to grow without overcrowding neighboring plants or structures.

Account for Growth: While Autumn Lilac Azaleas may start out relatively small, they can spread and fill out over time. Leave enough space between plants to accommodate their mature size and prevent overcrowding as they grow, ensuring a well-balanced and visually appealing landscape.

Site Conditions: Consider the site conditions, such as soil quality, sunlight exposure, and airflow, when spacing Autumn Lilac Azaleas. Providing adequate space between plants allows for proper air circulation, reduces the risk of disease, and promotes healthy growth and development.

By following these spacing guidelines, you can ensure that your Autumn Lilac Azaleas have enough room to thrive and create a stunning focal point or border in your garden.

Encore Azaleas are renowned for their ability to bloom not only in spring but also sporadically throughout the summer and into fall.

After planting azaleas it's essential to provide consistent moisture to help them establish a healthy root system. Here are some guidelines for watering newly planted azaleas:

Initial Watering: Immediately after planting, thoroughly water the azalea to settle the soil around the roots and remove any air pockets. Ensure that the entire root ball is moistened.

First Few Weeks: During the first few weeks after planting, monitor the moisture level of the soil regularly. Water the azalea deeply whenever the top inch of soil feels dry to the touch. Aim to keep the soil consistently moist but not waterlogged.

Weather Conditions: Adjust the frequency of watering based on weather conditions. During hot, dry periods, or if there's little rainfall, azaleas may require more frequent watering to prevent drought stress. Conversely, reduce watering during periods of rain or cooler weather.

Mulching: Apply a layer of organic mulch, such as shredded bark or wood chips, around the base of the azalea to help retain soil moisture and regulate soil temperature. Keep the mulch layer about 2-3 inches thick, but avoid placing it directly against the stems of the plant.

Avoid Overwatering: While azaleas prefer consistently moist soil, they are sensitive to waterlogged conditions, which can lead to root rot and other problems. Avoid overwatering by allowing the soil to partially dry out between waterings.

Established Plants: Once azaleas become established, typically after the first growing season, they may require less frequent watering. However, continue to monitor soil moisture and provide supplemental watering during dry spells or periods of drought.

By following these watering guidelines, you can help ensure that newly planted azaleas, such as the Rhododendron ‘Conlea’, establish healthy roots and thrive in their new environment.
