Rose Blackspot is a serious fungus with symptoms that show up around mid- late May. Warm, wet weather or overhead watering really sets it off
ABOUT ROSE BLACKSPOT
Blackspot is a common fungus on roses:
Spores survive winter in fall leaf debris and mulches. Mulch that overwintered in rose beds should be removed, discarded and replaced with fresh mulch every spring.
The disease begins on lower leaves and moves up the plant.
Heavily infected canes have raised red-purplish spots that eventually blacken, and it may be necessary to remove them to prevent spores from infecting the following year.
Control products should be applied beginning at the first sign of disease and follow up treatments will be needed. Soil Service Garden Center has several products available. Treat sooner rather than later.
Over the past 4-5 years we’ve seen a ton of sawfly damage on rose leaves so we suggest you start looking for damage now.
ABOUT ROSE SAWFLY
The rose sawfly is not a fly but is related to bees and wasps. The larvae, also called rose slugs, begin feeding in mid-late spring and, depending on species, can have multiple generations per year. This means several insect control applications may be needed during the summer. Sawfly feed on green leaf tissue but not the leaf veins, causing a netted appearance on the leaves that may be confused with Japanese beetle feeding but shows up in May vs. mid-late June for Japanese beetle damage. Inspect both the upper and undersides of leaves to look for light green sawfly worms. Several control options are available at Soil Service.
Anyone growing tomatoes knows they can be a bit of a challenge. Here are some helpful hints for growing better tomatoes.

Yellow nutsedge usually shows up around the end of this month, and if we have a lot of rain, we know it can really take off.
STAY ON TOP OF YELLOW NUTSEDGE:
We’re rapidly approaching the end of fertilizing fescue or bluegrass this spring. If you choose to make one final application before next fall
If you regularly water your cool season (fescue and/or bluegrass) lawn during the summer OR you have not applied fertilizer this spring, this is your last chance to feed your lawn until September. This application has a couple of rules:
Fertility strategies for zoysia and bermudagrass are considerably different than fescue/bluegrass.
Unlike cool season grasses, zoysia and bermuda are fertilized in summer and prefer more of the quickly available nitrogen. For either grass:
While it’s too early to predict this summer’s disease problems, we can keep a few things in mind
BROWN PATCH FUNGUS IN FESCUE LAWNS
We have Ferti-lome F-STOP (liquid or granular) or Ferti-lome Systemic Fungus Control (liquid only) to help with control. Then we hope the weather cooperates!
Now is a great time to refresh your mulch with Soil Pep
CHOOSE THE BEST MULCH FOR YOUR NEEDS
Mulch helps soils hold moisture for less plant stress and lower water costs. It also keeps down weeds. That’s the easy part. Our most popular mulch is Soil Pep, a partly decomposed small pine bark mulch. Soil Pep keeps its rich dark brown color without fading like dyed mulches. It also doesn’t crust over like the least expensive mulches. Those are two strong points right there. Like all mulches, Soil Pep eventually breaks down and makes an excellent soil amendment, especially when you prepare new beds with our heavy clay soils. You and your plants will be glad you used “Pep” this year!
We’re about out of time to treat Emerald Ash Borer. We have Ferti-lome Tree and Shrub Drench on hand, and it needs to be used no later than mid-May.
If you grow cabbage, collards, mustard, kale or broccoli, be on the lookout for a white butterfly
GET READY FOR CABBAGE WORMS
This seemingly innocent insect flutters around the plants and lands for 10-15 seconds to lay eggs. The real fun begins when the eggs hatch.
These worms are well camouflaged and have voracious appetites. They love to make holes in leaves. The good news is that the worms are controlled with several products, so keep your guard up on this food robber!
