How to Grow Boxwood Shrubs
Introduction:
Boxwood shrubs, known for their dense foliage and versatile shapes, are a timeless favorite among gardeners. They can be shaped into hedges, topiaries, or left to grow freely for a lovely, natural appearance. If you’re considering adding boxwood shrubs to your garden or landscape, here’s a complete guide on how to grow and care for them successfully.
1. Choose the right varieties:
There are different types of boxwood shrubs available, each with its unique features. For instance, Common Boxwood (Buxus sempervirens) is often used for hedges due to its sturdy and upright growth while the English Boxwood (Buxus sempervirens ‘Suffruticosa’) is great for borders because of its low-growing habit. Research various varieties and choose one that suits your purpose and climatic conditions.
2. Plant during the appropriate season:
The best time to plant boxwoods is during early fall or spring when the soil is workable. This will allow the roots to establish well before the hot summer months or winter frosts.
3. Choose the location wisely:
Select a location that provides space for growth and accommodates their sunlight requirements. Boxwoods generally prefer partial shade to full sun exposure but may require additional protection in excessively hot climates.
4. Prepare the soil:
Boxwoods thrive in well-drained soil with a pH level between 6.5 and 7.5. Amend your soil with organic matter such as compost or aged manure if required for improving drainage and fertility.
5. Space plants adequately:
When transplanting young boxwoods, maintain a distance of at least 3 feet between small varieties, while larger varieties may need up to 5 feet spacing. Proper spacing ensures good airflow and prevents overcrowding, which can eventually lead to diseases.
6. Watering and Mulching:
Regular watering is crucial, especially during the first two years of growth. Water deeply but less frequently to encourage the development of a healthy root system. A layer of mulch around the base of the plant retains moisture, suppresses weed growth, and maintains soil temperature.
7. Pruning and Shaping:
To maintain a desired shape or height, prune your boxwood shrubs annually or semi-annually. The ideal time for pruning is late winter or early spring before new growth begins. Always disinfect pruning tools before use to prevent the spread of diseases.
8. Monitor pests and diseases:
Boxwoods are susceptible to various pests, including leaf miners and spider mites, and diseases like root rot and box blight. Inspect plants regularly for signs of infestations or infections so that prompt action can be taken if necessary.
9. Fertilize appropriately:
It’s advisable to fertilize boxwoods once a year during early spring. Use slow-release balanced fertilizer such as 10-10-10 or organic alternatives like bone meal and fish emulsion to promote healthy growth.
Conclusion:
With proper care and attention, your boxwood shrubs will provide years of beauty to your garden or landscape. Implementing these tips will ensure that your boxwoods grow healthy, attractive, and resilient for years to come.
