It's possible that spring is finally here. The 15-day forecast shows night temperatures above 50 degrees consistently, which bodes well for annuals and tropicals (we can stop hauling plants back and forth to the garage) and means we can cautiously believe spring has sprung. Cautiously. Either way, here's your May garden chores. It's up to you if you bother with them. After this crazy winter and half a spring, if you're only of a mind to pour a glass of tea and sit outside with your feet up, basking in sunshine, go for it.
Immediately after blooming, if they need shaping or resizing, prune your azaleas, rhododendrons, lilacs and other spring-blooming shrubs. The best time is when blooms are discolored, shriveled and hanging on the shrub. Spring-blooming shrubs bloom on old wood (wood produced this season), so the sooner you prune, the better display of blooms you'll have next year. The longer you wait, especially if you wait until late summer or fall, you'll have less or no blooms.
Shape up shrubs or hedges that are outgrowing their spots, but don't remove the stems of spring-blooming bulbs like daffodils or tulips until they turn yellow. Resist the urge to pull them up and you'll have better flower production next year.

May is a good planting month. Since plantings are up, it's easier to see the gaps in your garden. Now you can match colors, fill in holes, add repetition, get rid of the onesies-look, be aggressive on what needs to go and keep the goal of unity in the landscape.
Before you buy, ask yourself:
- What is my sunlight/shade exposure? Determine the exact amount of sunlight hours during different times of the day. Do you have morning sun, afternoon shade? Is it direct or dappled? Full sun, western exposure? Study your landscape.
- What are the soil conditions? Dry, moist, always wet?
- Does the plant fit into the allocated space when it is mature?
- At maturity, will it create the necessary shade or too much shade?
- How does it blend/contrast with all of the garden?
- Does it compete with established focal points?
- Does it need to be evergreen or deciduous? Spring, summer or fall flowering? Tree, shrub or perennial?
- What plants would combine (contrast in color, texture, height, etc.) with these?
Start now with the weeding. You'll have a better chance of getting ahead of them. Weeding prior to putting down more mulch is best because the mulch won't kill the weeds already showing. Knowing your weeds is the first step to combating then. Below are two reliable sites for weed identification..
If you haven't already, then get to the mulching. Mulch beds 2-3," and though you've heard it before, let's say it again: avoid the candle in the cupcake look around your trees. You should always be able to see the root flair of a tree. That doesn't mean you can't mulch around it, that means 2" is plenty. Mulch gives a groomed look, and tidies the garden up, but it's purpose is much more than decorative. Read here for the benefits of mulching. Also, consider a living mulch. Many plants make a great ground cover and reduce the need for mulch. A few groundcovers are listed below, but visit the store to see the Toe Ticklers, Jeepers Creepers and Stepables for more.

5. Plant Annuals & warm Season Vegetables
The annual frost date of Mother's Day is almost over (a week from today, don't forget Mom). So, plant begonias, coleus, marigolds, petunias, and zinnias this month (and so many more), in the landscape or containers. Annuals are great for all season color, helping out when the perennial plantings are between bloom.
Vegetables you can plant now are: Cantaloupe, cucumbers, okra, pumpkin, watermelon, and squash.
Fertilize summer blooming plants like crape myrtle, rose-of-sharon and roses this month. Also, fertilize vegetables six weeks after germination. Once the weather starts to really warm up and the watering schedule increases, remember to fertilize annuals every 7-10 days with a bloom booster for better blooms.
7. poison Ivy and Ticks
May is National Lyme's Disease Awareness month, so start doing the tick check when you come in from the garden, and stay alert for poison ivy. Keep a bar of soap next to the hose and stop to wash hands and arms thoroughly every hour while working in the garden.
