May Garden Checklist

"Maple of the Month"

Be sure to check our website as we feature a new "Maple of the Month" each month.  Mention the website when you come in and receive 20% off that particular Maple for that particular month!  Also, use our Maple Selector to see which variety best suits your area. 

 

Roses: 

 

Continue feeding them every 4-6 weeks with Master Nursery Rose & Flower Food.

 

Powdery mildew (white mildew covering flower buds and/or leaves) may show up on your roses this month.  See our "How-To" Guide on Controlling Powdery Mildew for information on how to combat it.

 

Black spot, rust and many other fungal diseases are due to appear. Green Light Rose Defense will keep most of these in check.

 

Lawns:

 

Now that the ground has dried out it's a good time to core your lawn to help replenish it for the Summer.  See our "How-To" Guide on How To Save Your Lawn for details.

 

Raccoons digging up your lawn or new sod?  They're going after the grubs so apply Advanced Lawn Grub Control to kill the grubs and send the raccoons to someone else's yard!

 

Thinking of laying a new sod lawn?  Be sure to check our "How-To" Guide for New Sod Care.

 

If you have had problems with Bermuda grass in your lawn last year, it's about that time when it will reappear.  Begin spraying with Turflon Ester, which controls broadleaf weeds as well as Bermuda grass in established lawns.

 For oxalis and spurge, use Master Nursery Broadleaf DSO Weed Killer.  It can be sprayed over entire lawns. Because of the aggressive nature of oxalis several applications will be needed.

 

Flower Beds:

 

Summer annuals are aplenty!  It's time to plant Marigolds, Petunias, Alyssum, Lobelia and Cosmos just to name a few.

 

Got spit?  That is, a spit-like foamy substance on your shrubs?  It's only "Spittlebug" and can simply be hosed off with a sharp jet of water.

 

Snails and slugs are as active as always so be sure to keep plenty of Master Nursery Pest-Fighter Slug and Snail Bait on hand.  Have pets or kids?  Use either Sluggo or the Snail Jail and send those pesky snails to "The Big House"!

 

To control Bermuda grass and crabgrass and other weedy grasses in ornamental beds use Grass-Getter.  It kills grassy weeds without harming desirable plants.

 

Citrus:

 

Now it's finally warm enough to select and plant citrus.  See our "How-To" Guide on Caring for Citrus.

 

Time to feed them with Master Nursery Citrus Food.

 Watch your citrus for signs of scale.  They'll look like brown bumps along the stems, on new growth and the undersides of leaves. If found, spray tree with Master Nursery PestFighter Year-Round Spray Oil.  Wait 10 days between applications, and never spray oil more than four times during the growing season.

Ants on the trunk of your plants usually indicates the presence of scale.  The ants are farming the scale while fighting off natural predators.  Wrap the base of the trunk with Tangle Guard tree wrap and apply a coating of Tanglefoot to the wrap.  Tanglefoot creates a sticky barrier that ants cannot cross.  When the Tanglefoot becomes dirty simply remove the tree wrap and start over again.

 

Vegetables: 

 

Snails and slugs are as active as always so be sure to keep plenty of Master Nursery Pest-Fighter Slug and Snail Bait on hand.  Have pets or kids?  Use either Sluggo or the Snail Jail and send those pesky snails to "The Big House"!

 

Time to plant tomatoes, peppers, eggplants, squash, corn, basil, green beans, cucumbers, and melons from starts. Remember to amend soil liberally, as vegetable crops deplete nutrients from soils rather quickly. We like Paydirt, which includes chicken manure, plus an application of Master Start all worked into the top 4 to 6 inches of soil.

 

Aphids or whiteflies attacking your vegetables?  Spray them with Master Nursery Tomato and Vegetable Insect Control.  This safe, non-chemical spray can be used up to the day of harvest.

 

In General: 

 

Lady Bugs and Praying mantids are available now to place in your garden.  These natural predators host on many of the "bad bugs" that are eating your plants.  Tie a praying mantid egg sack in one of your shrubs and let them hatch and work their way around your yard.  Lady bugs should be spread around the base of your infested plants - but only release them at night so they don't fly away.

 

It's time to prune your Azaleas and Camellias.  Wait until they have finished blooming before tipping them back.  Remember, If you wait too long to prune them you will be removing next years flower buds.

 

Watch for Thrips on your Azaleas and Rhododendrons.  The symptoms are a general grayish, stippled look to the leaf tops while the underside has shiny black tar-like specs.  See our "How-To" Guide on Azaleas, Camellias & Rhododenrons for care instructions.

 

Time to lay down a layer of Master Nursery Goldrush.  This topdressing serves many purposes including keeping weeds in check, smothering overwintering fungus spores, keeping roots cool as the weather warms, and most importantly it will break down during the course of the year adding much needed organic matter to your soils.

 Watch for powdery mildew on your plants.  A white powdery substance that forms mostly on new growth and flower buds, powdery mildew especially affects certain plants such as Roses and Crape Myrtles.  See our "How-To" Guide on Controlling Powdery Mildew for information on how to combat it.
