The poster child for traditional formal gardens, boxwood has seen its ups and downs in popularity over the years—but it always seems to bounce back. Because boxwoods are easy to manipulate and maintain into so many different shapes and sizes, they can always find a home in formal settings. And with their timeless glossy green leaves, they easily add elegance to any garden space.

Garden Plans For Boxwood
What brings people back to these tried-and-true plants is their ability to be shaped into different formal structures. It is difficult for most plants (that are constantly growing) to be constrained in such a formal matter, but not with boxwoods.
Typically, boxwoods have one major flush of growth in the spring, but usually won't outgrow its shape because of its dense branching. With regular annual trimming, you can maintain a shaped plant with very little fuss. One important thing to note is that trimming is best done during late winter or early spring, just before the big annual flush of new growth. This prevents too much tender growth in the fall that may burn come winter, and promotes good branching of the new growth for a nice full shrub. See more plants for hedges.
Boxwood Care Must-Knows
Always assess the planned site for your boxwood before choosing a plant variety. There is a surprisingly large amount of boxwood varieties on the market, and each of these varieties has a specific growth habit and site requirement. Many varieties are very versatile in their sunlight needs and are able to take full sun to full shade, while others thrive in more shade and suffer burning and bronzing in too much sun. Bronzing is the most common problem seen in boxwoods and is generally due to too much sun and wind exposure during winter months. It is best to avoid planting most boxwoods in southwestern exposures. There are varieties more resistant to bronzing, so by choosing the correct variety from the beginning, you can prevent many potential boxwood problems.
The particular variety also tends to dictate what shape the plant will be best for, so check the growth habit of your specific variety before sculpting. Some boxwoods are naturally rounded, some are low and spreading, some are more conical, and some upright. The growth rate is also important to consider. Many dwarf varieties are slow-growing, so if you plan on making a hedge, you'll need to plan spacing accordingly. Others may be fast-growing and, if you plan on making intricate-shaped topiaries, they may outgrow their shape too quickly and require additional maintenance. Try landscaping boxwood with roses.
As a general whole, boxwoods are fairly forgiving plants. The most important thing to consider is that they like good drainage and do not appreciate standing water. When you plant your boxwood shrubs, make sure to plant them slightly above soil level and mound extra soil up just to the base so that water will not pool right at the crown. Once established, boxwoods can handle drought very well (but they do enjoy a little water every now and then to help prevent long-term problems). It is also important that boxwoods are well-watered as winter approaches. Watering them before a hard freeeze helps fill any air space around the roots and acts as insulation.
