I’m Only Humid

A gardener’s zest for yard work can wilt in August. We’re only “humid” and I understand. Yet in August some of the best entertaining days in the garden are for us to enjoy. From Rudbeckia to Sedums to Buddleia the landscape continues to entertain. With a little TLC and the willingness to wet our “plants” the landscape can reward our senses like an ornamental grass and its wispy dance in the warm summer breezes.

I love the month of August and it’s the gateway to some of the best gardening months of the year. This is no time to throw in the “trowel” on the yard and garden. Besides, now is the time we are rewarded with the fruits of our labors harvesting the tomatoes and peppers we lovingly planted months ago.
August is a great time to rejuvenate our flowering landscape annuals and give them a kick in the plants! Chopping back stretched, tired or leggy annuals and then feeding with a water soluble fertilizer will give them new life.

They’ll kick back into gear and produce a new flush of growth and color well into October. Mums and Asters become available starting in August to supplement your rejuvenated annuals for continuous color. In addition ornamental grasses take center stage in August and September as drought and heat tolerant extroverts in your yard. This is also the month for panicle Hydrangeas like PG, ‘Limelight’ or ‘Little Lamb’ to take center stage in the landscape with their stunning cone shaped blooms. Easy to grow and reliable they put on a show in August and September.

August is also a month to think about having that lawn you’ve always wanted. The best time to seed or over seed or establish a new lawn is mid August to October 1. The soil is nice and warm and if you kill unwanted vegetation grass seed will establish nicely as we head into fall. I still believe August 15 to October 1 is the best time of year in Michigan to establish a little “lawn” and order. Remember also that newly hatched grubs do most of their damage to a lawn in August and September, especially if the lawn is thirsty. If you did not apply a grub control in July you still have time this month while the young grubs are feeding near the surface. If you apply now you shouldn’t have to apply next spring.

Keep vegetable plants like tomatoes well watered so they keep producing and be watching for those miserable tomato hornworms on the plants. Head outside in the evening hours with a bucket of soapy water and pick them off the plants to drown their sorrows in your bucket of soapy water. Plenty of water at the base of your tomatoes and the calcium supplements you added earlier in the season will avoid the unsightly blemishes and “zippering” of the fruit you long to pick.
Unfortunately this also the month to be vigilant in inspecting under decks, patio furniture, mailboxes and other hiding areas for European Paper Wasps. These unwelcome guests pack a wallop of a sting when disturbed and have become much too common in our late summer landscapes. Look for the “paper”-like nests attached to railings or under patio furniture and spray from a distance with a knock down stream of wasp control spray.

Don’t let your enthusiasm wilt in the heat of August. We’re only “humid” and the garden party has just begun. See you in September.
