August Gardening Calendar

by Andrea Peters
  • With increased temperatures watering is even more important. Check out our selection of Dramm watering supplies.
  • To keep your annual flowers looking their best all season feed weekly with fertilome All Purpose Water Soluble Plant Food.
  • Keep faded flowers pinched off bedding plants to promote further flowering and improve plant appearance
  • Remember to feed roses monthly with fertilome Rose & Flower Food with Systemic Insect Control to keep them performing their best.
  • Divide and reset irises, plant with Bone Meal.
  • You want to cut grass higher in the summer and ONLY FEED with SLOW release nitrogen products by Shaw’s Turf & Milorganite are good to use.
  • pray Weed Out Nutsedge Control to kill nutgrass & crabgrass.
  • Pick beans, tomatoes, peppers and squash often to encourage further production.
  • Harvest sweet corn when kernels are plump and ooze a milky juice when punctured with your fingernail. If the liquid is watery, you’re too early; if the kernels are doughy, you’re too late.
  • Harvest watermelon when several factors indicate ripeness – the underside ground spot turns from whitish to creamy yellow; the tendril closest to the melon turns brown and shrivels; the rind loses its gloss and appears dull; and the melon produces a dull thud, rather than a ringing sound when thumped.
  • Harvest onions after the tops yellow and fall, then cure them in a warm, dry, well-ventilated area. The necks should be free of moisture when fully cured in about a week’s time.
  • Harvest potatoes after the tops yellow and die. Potatoes also need to be cured before storage.
  • Treat your tomatoes with Hi-Yield Calcium Nitrate to add calcium and prevent blossom rot, check tomatoes for early signs of blight-treat accordingly.
  • Now is a great time to plant cole crops: we currently have broccoli, cauliflower, cabbage, lettuce, kale & fall tomato plants ready
  • Complete fall garden planting by direct-seeding carrots, beets, kohlrabi, kale and snap beans early this month. Lettuce, spinach, radishes and green onions can be planted later in August and early September. Don’t forget to thin seedlings to appropriate spacing as needed.
  • Summer is also the season for bugs. Check for bagworms, tent caterpillars, scales, lace bugs, spider mites, and much more. We are here to help. If you have questions, please take a picture and send in Facebook Messenger or bring it into the store. Please do not bring live samples in to prevent infesting our plants.
  • Keep an eye on houseplants you have set outside. You don’t want to let them go too dry or get infested with bugs.
