Terrascape’s Pruning Guide
Spring is the official "wake-up call" for your garden. While it’s tempting to head out with shears the moment the sun comes back from Winter vacation, pruning is as much about restraint as it is about removal. Think of it as a haircut: do it right, and your plants look fabulous; do it wrong, and you’re waiting a year for the bangs to grow back.
1. The Key Tools: 🔨
Before you make the first cut, ensure your tools are sharp and sanitized. Dull blades crush stems rather than slicing them, leaving the plant vulnerable to disease.
Bypass Pruners: These work like scissors (overlapping blades). Best for live wood and precision.
Anvil Pruners: These have one sharp blade that hits a flat metal base. Use these only for dead, brittle wood, as they can crush living tissue.
Loppers: For branches thicker than a pencil (up to 2 inches).
Pruning Saw: For anything larger than 2 inches.
Rubbing Alcohol (70%): To wipe your blades between plants to prevent the spread of pathogens.
2. The Triple D’s: 🍡
Clearing these out immediately improves the plant's health and air circulation.
Dead: Wood that is brittle, brown throughout, or snaps easily.
Damaged: Stems cracked by ice, wind, or heavy snow.
Diseased: Wood showing signs of cankers, strange fungus, or oozing.
3. Timing Your Cuts 🕕
Pruning at the wrong time can accidentally remove this year's flowers. Use the table below to hone your strategy:
Summer-Blooming Shrubs | Late Winter / Early Spring | They bloom on "new wood" (growth produced this year). |
Spring-Blooming Shrubs | Immediately after flowering | They bloom on "old wood" (growth from last year). |
Evergreens | Mid-to-Late Spring | Best handled once new growth (candles) starts to appear. |
4. Species-Specific Instructions: 🌹
Roses:
Cut back to about 6–12 inches above the ground for bush roses.
Remove any "spindly" growth thinner than a pencil.
Always cut to a bud or node to encourage the center of the bush to stay open for airflow.
Hydrangeas:
Smooth/Peegee Hydrangeas: These bloom on new wood. You can cut them back significantly (even to 12 inches) in early spring to encourage massive blooms.
Bigleaf/Oakleaf Hydrangeas: These bloom on old wood. Do not prune these in spring other than removing dead tips, or you will lose your flowers for the season.
Perennials:
Ornamental grasses and perennials left standing for winter interest should be cut back to about 2–3 inches from the ground before the new green shoots get tall enough to be accidentally nipped.
5. Cutting Technique: 🔪
The Angle: Always cut at a 45° angle.
The Direction: Slant the cut away from the bud. This ensures that rainwater runs off the cut and away from the delicate new growth, preventing rot.
The Distance: Aim for about 1/4 inch above a bud. Too close and you kill the bud; too far and you leave a "stub" that will rot and invite pests.
6. The Cleanup: 🧹
Don't leave your clippings at the base of the plant. Dead wood and old leaves are the preferred high-rise apartments for pests and fungal spores.
Discard Diseased Wood: Don’t compost diseased cuttings; put them in the trash.
Mulch: After pruning, apply a fresh layer of organic mulch to help retain moisture as the plant works to heal and push out new growth.
Hydrate: Pruning is stressful. Ensure the plant is well-watered if the spring has been particularly dry.
Happy gardening!
