The hydrid Kordesii Rose John Davis is a hard-working rose that blooms periodically from June to September on new wood. Prune it in late winter for the strongest show all season.
Late winter to early spring is a terrific time for pruning many shrubs. What should you prune and when? You could study pruning for an entire semester, but here are some basic guidelines. I recommend that you properly identify, then research, each particular kind of woody plant before you consider your first cut:
Safety first 1) If any part of a tree or shrub is within ten feet of any kind of electric cable or wire, stop and call a professional. 2) Wear gloves and sturdy shoes, and use only sharp tools like bypass (not anvil) hand pruners and loppers, and saws. 3) Sanitize your tools and gloves with isopropyl alcohol or a product like Lysol spray before you start, and again when you’re done pruning each individual plant.
General concepts Notice the overall shape of the shrub. Most flowering shrubs should be balanced and open in their center. Start pruning by removing all dead and diseased branches, then look for branches that cross or touch each other. Rubbing branches damage the bark tissue, inviting pathogens and pests, so remove one or both branches, depending on their condition, all the way to the base. Branches that grow from the perimeter towards the center should usually be removed. To shorten a branch or twig, cut it 1/4 inch above an outward-facing bud so new growth heads towards the perimeter of the shrub.
When does your shrub bloom? 1) For spring bloomers, pruning them during the late dormant period (late winter/early spring) will remove flower buds, which were formed last year after the shrub bloomed. No flower buds, no flowers, so wait until after they bloom this year. 2) For later bloomers, pruning them now, before they form this year’s flower buds, is ideal. These can also be pruned soon after blooming.
Roses Relax. Roses are simply shrubs that benefit from annual pruning. Prune in late winter to early spring (late dormancy) or when the buds start to swell. First cut out dead, broken, diseased and crossing canes. Put all your pruning debris in a trash bag and throw it away. Do not compost. Fertilize your roses with something like Espoma Rose-Tone or a good organic slow release fertilizer by following the directions on the bag. Climbers like to keep their main stems, so keep them fresh by pruning their lateral branches. Once the main stems are three years old, consider cutting one or two of them to their base to encourage new ones. Then cut one or two of the oldest every year. For shrub roses, cut up to 1/3 of the canes, the oldest, thickest woody ones, to their base as you open up the overall look to a vase shape. Cut to their base any super skinny canes from last year. For height, cut the remaining canes to about 1/2 their height, 1/4 inch above a robust outward-facing bud.

What do you do keep your drought-stressed plants alive this winter? It’s hard to put a Band-Aid on drought-stressed plants, but here are some things you can do:
KEEP WATERING UNTIL THE GROUND FREEZES IN THE FALL/EARLY WINTER. Check with your city or town to see if even now, in late December, there’s a current watering ban. Especially with new plantings, and also with drought-stressed ones, you generally want to give them the equivalent of one inch of water per week all the way until the ground freezes. If time or water is limited, focus on watering your most valuable plants, such as trees and shrubs.
IMPROVE YOUR SOIL. On your lawn for instance, just 1/4 inch of compost every fall makes a huge difference in the resilience of your turf plants. For your planting beds, pull back the mulch, spread 1/2 inch of compost or leaf mold, scratch it into the soil surface, and put the mulch back in place. This will increase the soil’s ability to hold moisture and make nutrients more available to the roots of your plants. Think in terms of feeding your soil (the soil food web), not feeding your plants.
MULCH. It’s not to late to apply 2-3 inches of mulch to all areas of exposed soil. Do not let mulch come in contact with the trunks of your trees and shrubs, where it transitions into the root. This area is called the root flare and should never be covered. If you see a mulch volcano around the base of a tree, the mulch is suffocating the tree, which stresses it, makes it vulnerable to pests and pathogens, and puts the tree on a path of decline. About the best mulch of all is fallen leaves that you’ve chopped up with your lawn mower and spread on your beds. Speaking of chopped leaves, you can also pile them up, adding water to create a water film on most of the leaf surface area, and let them sit for a year or two. The result, called leaf mold, is another source of organic matter that will make your plants sing.
PLANT NATIVES. Many people picture native plants as being weedy and leggy. In fact, native plants are best adapted to not only survive, but thrive in the existing environmental conditions. Test your soil and know how much sun your planting site gets. Then, it’s easy to select plants that should do quite well with minimum inputs, once established.
