Wake Up
Early maintenance chores aren't just about tidying up your garden and making it look pretty, it's an opportunity to identify and fix problems to insure its best performance later on. It helps to understand the reasons behind the chores you're doing so you know what to look for while you're out there slaving away.
Practice early staking
Put stakes around potential floppers when they are up about 6 inches. It's much easier to stake plants before they get too big and it looks better later because they grow into the staking you've put in place and you don't see it.
What should you do about vines?
Clematis: Cut back about a foot above the ground. Forget about pruning clematis once they leaf out - handling them causes their foliage to bruise and wilt. It's impossible to disentangle the dead foliage from the live and you end up cutting off future flowers. It is important to identify what variety of clematis you have to determine whether it blooms on old or new wood. If it blooms on new wood, you can cut it back now, prune those that bloom on old wood after they bloom. If you don't know, wait until you can identify it.
Woody vines: Wisteria, trumpet vine, and climbing hydrangea can be pruned back now if they are overgrown. Wisteria should be pruned very early (March). Otherwise, wait until after it has flowered.
Honeysuckle vines (Lonicera) tend to get lanky and accumulate dead wood in the center. These are hard to prune once they have leaves and flowers on them. Try cutting back by half every few years to get rid of the dead wood and promote better growth.
To feed or not?
Find out what your soil needs by taking a sample and testing it for soil pH and nutrients. Most county agricultural extension agencies provide this service, and you can take your sample to them to have it tested. They'll provide you with a report on the nutrients in your soil and recommendations on feeding. If you have more than one bed, take samples from different areas to get accurate results. Keep improving your soil by top dressing beds with compost, amending problem areas, and digging in compost when you're planting.
What about mulch?
It may look nice, but too much mulch can suffocate perennials and damage trees and shrubs. Limit mulch to about 1-2” in depth. Keep it away from the trunks of trees and shrubs.
Plan ahead
Don't wait until the end of May to start digging out your hoses and sprinklers. Fighting with leaky connections, kinky hoses and sprinklers that don't work when you're in the throes of planting takes all the fun out of gardening. Stock up on stuff like stakes, twine, fertilizer and so forth so you'll have it around when you need it. Let the games begin!
