Care Guide
Planting:
- Plant heather in well-drained soil.
- Choose a location that receives full sun or partial shade.
- Dig a hole twice the width of the root ball and just as deep.
- Place the heather plant in the hole and backfill with soil, tamping down gently to remove air pockets.
- Water thoroughly after planting.
Watering:
- Water regularly, especially during the first growing season.
- Heather requires approximately one inch of water per week.
- Once established, heather has average water needs, but may require more irrigation in warmer zones.
Mulching:
- Mulch around heather plants with organic matter, such as shredded bark or compost.
- Mulch helps retain moisture, suppress weeds, and regulate soil temperature.
Fertilizing:
- Fertilize heather sparingly with an acidic-leaning fertilizer once a year in early spring.
- Avoid over-fertilizing, as it can lead to leggy growth.
Pruning:
- Prune heather in early spring to remove dead or damaged stems.
- Pruning also helps maintain a compact, bushy shape.
Propagation:
- Heather can be propagated by cuttings, seeds, or division.
- Cuttings are the most common method and can be taken in the summer or fall.
Common Problems
Powdery Mildew:
- Powdery mildew is a fungal disease that can affect heather.
- It appears as a white or gray powdery coating on the leaves.
- To prevent powdery mildew, avoid overhead watering and prune faithfully to improve air circulation.
Root Rot:
- Root rot is caused by overwatering or poorly drained soil.
- Symptoms include wilting, yellowing leaves, and stunted growth.
- To prevent root rot, ensure that the soil drains well and avoid overwatering.
Browning Foliage:
- Browning foliage can indicate a variety of issues, such as drought, nutrient deficiency, or root rot.
