Barberry Bush Care Tips: How to Grow a Barberry Bush

A barberry bush (Berberis vulgaris) is an evergreen shrub that yields red berries and yellow flowers. Barberry bushes are commonly used as foundation plantings due to their adaptability to different growing conditions. They make good landscaping plants alongside hydrangeas and boxwoods and have an upright, columnar growth habit, making them popular doorway frame plants. Japanese barberry (Berberis thunbergii) is one of the most popular barberry bush varieties, but it can become invasive in the northeastern part of the US.

The foliage colors of barberry bushes change starting in early spring. The green leaves of the barberry bush become orange or red by autumn. The barberry bush is deer-resistant, partially due to its very sharp thorns. The barberry bush is considered an invasive plant along the Northeastern corridor and parts of the Midwest. Be aware that the yellow flowers of barberry bushes are poisonous and should be kept away from pets.

Barberry bushes are easy to grow, hardy, and require little maintenance. Consider the steps required to grow a barberry bush from seed.

1. 1. Sow the seeds. Place the barberry bush seeds in trays with a mixture of equal parts compost and perlite. Keep your potting medium moist.
2. 2. Store seeds in a hospitable environment. Consistent temperatures of fifty-five to sixty-five degrees Fahrenheit are ideal for barberry bush seeds to germinate. Seeds should germinate within one month.
3. 3. Transplant the seedlings to pots. Once the seedlings reach three inches in height, transplant them to pots with potting mix. Maintain adequate moisture and plant the young plants in your garden when the seedlings reach a foot tall.

The barberry bush is hardy and requires little maintenance. Consider some growers’ tips to keep your barberry shrubs healthy.

1. 1. Light: Keep your barberry bush nourished in full sun with partial shade in the afternoon.
2. 2. Temperature: Temperate or subtropical climates help barberry bushes thrive. Regions that experience frost and freezing temperatures are not recommended for barberry bushes. Known for their hardiness, barberry bushes are drought-tolerant. USDA hardiness zones four through eight are generally best for the barberry shrub, but some barberry bushes may do well in zones three and nine as well.
3. 3. Soil type: Soil mixed with perlite or vermiculite works best for barberry bushes. Compost is useful for boosting the soil with extra nutrients. Add mulch to the top layer of the soil to help retain moisture.
4. 4. Watering: Water your barberry bush once a week in the summer and less frequently the rest of the year. Be cautious about overwatering your barberry shrub, as too much water can lead to root rot.
5. 5. Pruning: Prune your barberry bush a few times a year to manage its growth—especially if it is serving as an ornamental hedge or other similar horticultural uses.
6. 6. Pest control: Aphids and webworm may invade your barberry bushes. If this occurs, apply a gentle insecticidal soap or spray to manage infestations.
7. 7. Propagating: As an alternative to growing barberry bushes from seed, you may also propagate barberry bushes from stem cuttings. The new growth in early spring makes for ideal stem cuttings.
