- Site selection: Choose a location with well-drained soil and access to full sun or partial shade. While Autumn Inferno® Cotoneaster can tolerate some shade, it will produce the most vibrant foliage and abundant flowers when exposed to ample sunlight.
- Soil preparation: Ensure the soil is well-draining and loamy, as the plant is susceptible to root rot if left in waterlogged conditions. Amend heavy clay soils with organic matter like compost or well-rotted manure to improve drainage and fertility.
- Planting: Dig a hole slightly larger than the root ball of the Autumn Inferno® Cotoneaster, ensuring the depth is the same as the plant's container. Gently loosen the roots and place the plant in the hole, backfilling with soil and firming gently around the base. Water the plant thoroughly to settle the soil and eliminate air pockets.
- Watering: Water the Autumn Inferno® Cotoneaster regularly during the first growing season to help it establish a deep, extensive root system. Once established, the plant is relatively drought-tolerant and requires less frequent watering. However, it's essential to avoid letting the soil dry out completely, especially during hot, dry periods.
- Mulching: Apply a layer of organic mulch, such as bark chips or compost, around the base of the plant to conserve moisture, regulate soil temperature, and suppress weeds. Keep the mulch a few inches away from the plant's stem to prevent rot and pest infestations.
- Fertilizing: Feed the Autumn Inferno® Cotoneaster with a balanced, slow-release fertilizer in early spring before new growth begins. Follow the manufacturer's instructions for application rates and methods.
- Pruning: Prune the Autumn Inferno® Cotoneaster to maintain its shape and remove dead, damaged, or diseased branches. Pruning is best done in late winter or early spring, before the onset of new growth. Lightly thin the plant to improve air circulation and reduce the risk of disease.
- Pest and disease control: Autumn Inferno® Cotoneaster is relatively resistant to common pests and diseases. However, it's essential to monitor for issues like aphids, spider mites, or fireblight. Implement appropriate control measures if these problems arise, including insecticidal soaps, horticultural oils, or pruning affected branches and disposing of them properly.
