Growing heather in the United States can be a bit challenging, as the plant is native to cooler and moister climates like those found in Scotland and England. However, there are certain regions in the US where heather can thrive, particularly in the Pacific Northwest.
One of the best areas in the US for growing heather is the Puget Sound region in Washington state. The cool and damp climate of this region closely resembles that of its native habitat, making it an ideal location for heather cultivation. Gardeners in this area have been successfully growing heathers for a long time.
While California may not be the first place that comes to mind for growing heather, there are still some gardeners who have managed to grow this plant successfully in certain parts of the state. However, it is important to note that California’s climate varies greatly, and not all regions will be suitable for heather growth.
In general, heather prefers cool temperatures and well-drained soil. It can tolerate some drought conditions once established, but it still requires regular watering. If you live in a region with hot and dry summers, it may be more challenging to grow heather without providing extra care and attention.
If you are determined to grow heather in a region with a less-than-ideal climate, there are a few things you can do to increase your chances of success. First, choose heather varieties that are more tolerant of heat and drought. Some cultivars, such as Calluna vulgaris ‘Wickwar Flame’ and ‘Firefly’, have shown better resistance to warmer temperatures.
Secondly, provide the heather with adequate shade during the hottest parts of the day. This can be achieved by planting them near taller plants or providing them with some form of shade cloth or light shading.
It is also crucial to ensure that the soil is well-drained. Heather does not like to sit in wet soil, as this can lead to root rot. If your soil tends to be heavy or poorly drained, consider amending it with organic matter, such as compost, to improve drainage.
Lastly, regular watering is essential, especially during dry periods. Heather plants have shallow root systems, so they rely on consistent moisture. Mulching around the plants can help retain moisture in the soil and reduce weed competition.
While California may not be the most ideal place to grow hardy heathers, there are still gardeners who have managed to successfully cultivate them in certain regions. The cool and moist climate of the Pacific Northwest, particularly the Puget Sound area, is more suitable for heather growth. However, with careful selection of varieties and proper care, it is possible to grow heather in other parts of the US as well.
