May “to-do” list

For those of you who enjoy doing some work on your landscape, below are the things you can be thinking about right now. (Remember, if this isn’t your cup of tea, we offer maintenance services and we’re happy to do the “dirty” work for you.)This is not meant to be a comprehensive list. I tried to address some of the most common plants in this area, and some of the most pressing things to do during this month. If you have specific questions about your specific plantings, feel free to email me or do an online search.

are growing vigorously now. Save yourself a lot of work later in the season by eliminating them (roots and all) now, before they go to seed. Try weeding after a good rain– They are easier to pull out, and you’re likely to get more of the root.– may be planted late in the month.– If you planted them in April, you may begin to see the first fruit by late this month. To keep the birds from eating them, place netting over them. Newly planted strawberries should have the blossoms picked off until they become well established.– wait until mid to late May before planting. can be seeded or planted– may be divided and moved when they have finished blooming, but be careful not to damage the foliage or roots. Water them thoroughly after transplanting. It is best not to dig or move other spring flowering bulbs until their foliage has died back.– Break off wilting flowers but wait to remove foliage until it has died back naturally (yellowed and pulls out easily). Tying or folding the foliage will prevent the bulb from getting the nutrients it needs to flower next year., etc.)– can be planted this month. Planting Gladiolas bulbs every 2 weeks in May and June will provide you with cut flowers until the first frost.– cut back by about one-third once they’re a foot or so high. They’ll be sturdier and flower better.– Promptly remove wilted flowers from any plant, unless you want to harvest the seeds. This will help save the plant’s energy for blooming and growth, and in many species (especially annuals), removing the dead flowers promotes further blooms.– Stake your taller flowers early in the season (when they are about a foot high) to support the plant as it grows.– Lightly work an all-purpose 5-10-10 or 10-10-10 fertilizer around the sides of the plant. Avoid spilling the fertilizer on the plant, and don’t dig deep enough to damage the shallow roots when you cultivate it into the soil.– To encourage compact growth, pinch the ‘candles’ (new growth) to remove half of the new growth.– Use an ‘evergreen’ type of plant food.– Prune evergreens any time from now until late summer. (Don’t prune later than that or you’ll prompt new, tender growth that will get zapped during winter.)– Remove any sucker growths from fruit trees as soon as they appear.– To produce pink flowers, work lime into the soil around your plant. To produce blue flowers, work in Aluminum Sulphate.– Prune lightly after they finish blooming, removing sucker growths and dead blooms. Feed with an all-purpose 10-10-10 fertilizer after they have finished blooming (again, check out organic fertilizer options). If your soil has an acidic pH, work a little lime into the soil as well. etc.)– prune when they have finished blooming. Use the “1/3 rule”: cut back a third of the oldest canes to ground level. Then cut back one third of remaining branches by one third of their height.– Use an all-purpose garden fertilizer (10-10-10). You can also try fish emulsion, an organic fertilizer. Keep an eye out for aphids, black spot, and other pests and diseases. Treat if necessary.– If you haven’t already, use a ‘Rhododendron’ or an ‘Evergreen’ type of plant food. Pinch off the old flower heads by hand to focus the plant’s energy on growing foliage and next year’s flowers. Do this carefully because the tips of new growth are developing right behind the old flowers.– If you haven’t already, you can fertilize your plants. Check out your local garden center’s organic selection. Improper fertilization can do more harm than good, so be sure to follow the fertilizer instructions.– If needed, mulch under trees and shrubs to keep weeds down and retain moisture.
