Here are some key factors that can affect heather spread:

  1. Soil conditions: Heather prefers well-drained, acidic soil. If your soil is too wet or has a high pH level, it may not be suitable for Heather and could cause it to struggle or even die off. On the other hand, if the soil is too dry or sandy, Heather may spread more quickly.
  2. Climate: Heather is native to cooler climates and prefers mild temperatures. If your garden experiences extreme heat or cold may affect heather growth and spread.
  3. Light exposure: Heather requires a certain amount of sunlight to thrive, but too much or too little can affect its growth. If your garden is heavily shaded or receives full sun for most of the day, it could impact heather growth and spread.
  4. Water availability: While Heather doesn’t require much water, it needs consistent moisture to grow and spread. If your garden is too dry or wet, it could affect heather growth and spread.
  5. pH level: As mentioned earlier, Heather prefers acidic soil with a pH between 4.5 and 5.5. If soil is too alkaline, it could impact heather growth and spread.

By considering these factors and ensuring that your garden provides the right conditions for heather growth, you can help prevent it from spreading too aggressively. 

Be sure to choose a non-invasive variety and maintain it properly through regular pruning and weeding to ensure it coexists well with other plants in your garden.
