Overwintering Rooted Blueberry Hardwood Cuttings in Zone 7

Protecting Young Blueberry Plants Through Winter

By August, your March-struck hardwood cuttings have rooted and put on new growth. Now ensure they survive winter in Zone 7.

In-Ground Nursery Bed

• Apply 4–6 inches of straw mulch over the root zone after the first hard freeze.
• Ensure soil is moist going into winter; water during dry spells.
• If in a cold frame or hoop house, close vents and cover with plastic during severe cold.

Containerized Cuttings

• Move pots to an unheated garage or shed.
• Water once a week to prevent desiccation.
• Group pots together and mulch around them with straw or leaves.

Key Point

Well-rooted cuttings with active growth have a strong root system to draw water and nutrients. Zone 7 winters are mild enough that heavy mulch or a cold frame is usually sufficient.
