2. Dig a wide hole – Make it 2-3 times wider than the root ball but no deeper. The top of roots should sit slightly above ground level.
3. Amend soil if needed – Most NH soil is acidic. Add compost for drainage. Do not add fertilizer at planting time.
4. Water deeply – Give 1 inch of water per week for the first growing season. Mulch with 2-3 inches of bark or wood chips.
5. Protect from winter – Apply anti-desiccant spray to evergreens in late fall. Wrap burlap around vulnerable shrubs in exposed areas.

Maintenance Tips For Dwarf Shrubs

These plants need less work than full-size shrubs, but they still require basic care.

• Prune in late winter – Remove dead or damaged branches before new growth starts. Do not prune in fall.
• Fertilize lightly – Use a slow-release fertilizer formulated for shrubs. Apply in early spring only.
• Watch for snow damage – Gently brush heavy snow off branches. Do not shake ice off; it can break stems.
• Check for deer – Deer browse on certain shrubs like arborvitae and yew. Use repellent or fencing if needed.
• Divide or transplant – If a shrub outgrows its space, move it in early spring while dormant.

Common Problems And Solutions

Even hardy shrubs face issues in New Hampshire. Here is what to watch for.

• Winter burn – Brown leaf edges on evergreens. Prevent with anti-desiccant and wind protection.

Fertilizing Schedule For Dwarf Shrubs

Over-fertilizing harms shrubs more than under-fertilizing. Use these guidelines.

• First year – Do not fertilize. Roots need to establish without stimulation.
• Second year – Apply a balanced 10-10-10 fertilizer in early spring. Use half the recommended rate.
• Mature shrubs – Fertilize every other year. Use organic compost or slow-release granular.
• Acid-loving shrubs – Use fertilizer formulated for rhododendrons or blueberries. Apply in spring only.

Winter Protection Strategies

New Hampshire winters test even hardy plants. Take these steps to minimize damage.

• Water before freeze – Give shrubs a deep watering in late fall before ground freezes. Hydrated plants survive better.
• Mulch roots – Apply 3-4 inches of mulch around base after ground freezes. This insulates roots.
• Wrap evergreens – Use burlap or anti-desiccant spray on exposed evergreens. This prevents moisture loss.
