The size of the Golden Spirea, or Spiraea japonica ‘Goldmound,’ can vary depending on its growing conditions and pruning habits. Generally, this shrub has a compact and rounded form, reaching a height and width of around 2 to 3 feet (60 to 90 cm). However, with proper care and maintenance, it can potentially grow slightly larger.
When planting the Golden Spirea, it is important to consider its eventual size and allow enough space for it to grow and spread. If planted too closely to other plants or structures, it may become crowded and hinder its growth potential.
As with most shrubs, the Golden Spirea can benefit from regular pruning to maintain its shape and size. Pruning should be done in late winter or early spring before new growth begins. This will help stimulate healthy and vigorous growth throughout the growing season.
During the pruning process, it is recommended to remove any dead or damaged branches, as well as any overgrown or crossing branches that may impede the plant’s overall form. Additionally, thinning out some of the oldest stems can promote new growth and maintain the shrub’s vitality.
If you prefer a more compact and smaller size for your Golden Spirea, you can prune it more heavily. This will help control its growth and maintain a tidy appearance. On the other hand, if you want a larger and more natural-looking shrub, minimal pruning or selective pruning can be done to allow it to reach its full potential.
It’s important to note that while the Golden Spirea is a relatively low-maintenance shrub, regular watering, proper soil conditions, and adequate sunlight are also essential factors in promoting healthy growth. Providing these optimal conditions will contribute to the overall size and vigor of the plant.
In my personal experience, I have grown Golden Spireas in various landscapes and gardens. I have found that when given sufficient space to grow and regular pruning to maintain its shape, the Golden Spirea can flourish and provide a beautiful addition to any garden. Its compact size makes it versatile for various planting locations, including borders, containers, and even as a focal point in smaller garden spaces.
The Golden Spirea can be an excellent choice for those looking for a compact and colorful shrub that doesn’t take up too much space. With proper care and attention, it can reach a modest size while adding vibrant foliage and a touch of elegance to your outdoor spaces.
