We’ve had a lot of rain lately, which is unusual for Maryland this time of year. Usually we’d be experiencing Maryland’s annual summer drought and we would be giving you watering tips. But not this year. That is both good and bad. It’s good in that you are not lugging hoses all over the yard in the sweltering heat. But all the moisture, coupled with humidity and heat, can introduce a host of diseases and pests into your garden.

Take a walk in your yard and take a close look at your plants. Are there black spots on your roses? Is there a white powder on your crape myrtles? Do your tomato plant’s leaves have tan spots on them? Are there weird yellowish patches in your lawn? Afflictions like Powdery Mildew, Black Spot, and Gray Mold are common during wet spells like we are experiencing now and can show up almost overnight. In addition, the extra moisture can make your plants more vulnerable to insect pests. These diseases and pests won’t go away by themselves. They need to be treated as soon as possible before the damage they cause is severe.

Not sure what’s ailing your plants or unsure of how to treat it? Bring a sample of the diseased plant, like a leaf or a branch, into K&B True Value to try and stump our Garden Supply manager, Greg King. No one has been able to do it yet, but there’s always a chance, no matter how unlikely that might be! He can match you up with the most effective solution for your situation, whether it is a topical spray or a systemic drench and walk you through the correct application process. Greg is also knowledgeable about preventative measures you can take to help keep your garden and plants healthy such as planting lots of flowers to attract beneficial insects and “feeding” your plants well.

After you have the pests and diseases under control, make it a habit to take a leisurely walk throughout your property a few times per week, examining your plants, including under the leaves, for issues with mold or insects. These regular inspections allow you to hone in on problems early on, when you have the best chance of quickly solving the problem.

    On your Contorted Filbert (Harry Lauder Walking Stick) I would recommend using one of the following 4 products.
    1)Bonide Japanese Beetle Bug Killer Ready to use spray. This will kill on contact and can be repeated in 5-7 days. Do not spray more than 10 times in a season.
    2)Bonide Eight Insect Control RTU This can be applied once a month The Chemical is Permethrin.
    3)Bonide Systemic Insect Control. This must be used in a Tank Sprayer or Hose end Sprayer at the rate of 2 ounces per gallon. Spray once every 10-14 days. Usually 3 applications will take care of the beetles.
    4)Sevin RTU This product needs to be applied every 3-7 days . It is a topical control only.
    Make sure which ever one you choose it must be sprayed in the morning between 6 and 9 am or in the evening after 7 pm. Do not spray during the daytime because the chemicals could burn your plant especially in the hot sun. Thank you Greg King

    Greg is spot on. Don't miss a treatment. I lost a twenty year old plant last year because I hesitated. Recommend monthly vice less expensive (and effective) shorter cycle products.
