Although known for being tolerant of severe pruning, most boxwoods can develop a nice informal shape without much pruning. Only occasional pruning is required to remove dead or tangled branches.

When pruning is an effort for form, pruning can be done almost any time during the growing season, but should be avoided in late fall to avoid winter bronze.

Propagation of boxwood bushes

Boxwood is best propagated by rooting stem cuttings in midsummer. Methods as below:

  1. Cut 3 to 4 inches of stem tips from new growth with clean scissors. Remove the lower leaves and scrape the bark off one side of the cutting.
  2. Bury the ends of the cuttings in a container with a mixture of sand, peat moss and vermiculite. Moisten the potting medium and place the container in an airtight plastic bag in a bright place.
  3. Check the moisture daily and spray when the cutting is dry. Check the roots every few days by pulling the cutting.
  4. When the root system is fully developed, remove the pot from the plastic bag and transplant the cutting into another container with rich potting mix.
  5. Continue to grow plants in a sunny window until planting outside next spring.

How to grow boxwood bushes from seed

Growing boxwood bushes from seed takes a lot of time, but is usually successful. Start with a 2-inch pot filled with organic potting soil. Make sure the pot has good drainage holes; adding some gravel to the bottom will ensure better drainage.

Place the seeds in damp paper towels and store those paper towels in the refrigerator for a month. Make sure the paper towel stays moist. After the month is over, move the paper towels and seeds to a warmer location, around 70 degrees Fahrenheit. Keep the paper towels moist and expect the seeds to germinate in about a month.

After the seeds have germinated, plant sprouted side down in containers, one seed per container. Cover the container with plastic film and put it in a sunny place. Keep the soil moist. Remove the plastic wrap when green shoots appear above the soil. Nurture them in pots until they are too big for the pot, at which point they are ready to harden off and transplant outside.

Potted boxwood and transplanted

If you decide to grow boxwood in containers, choose a container that is as wide as the boxwood is tall. For example, if you have a 12" tall boxwood, you will need a 12" diameter pot. When it outgrows its current container, repot it into a container just a few inches larger, keep the soil moist and watch for signs that the plant is struggling - your soil may need an amendment.

winter

In the northern part of the hardiness range, new growth is easily damaged by winter. For the first few years, protect the boxwood with burlap or similar protection.

Miner, boxwood mites and boxwood leafhoppers are common pests. The damage is disfiguring but not fatal, and the pest can be treated with horticultural oil. In the Deep South, nematodes are a problem. Boxwood is susceptible to fungal blight and leaf spot, and root rot can also be a problem in poorly drained soils.
