  • It’s not too late to plant annuals. Cut back those that are slowing down and you will see a new burst of flowers.
  • Hardwood cutting of azaleas, fuchsias, hydrangeas and wisteria can be taken this month. Take cuttings and place them in a sterile sandy potting mix.
  • If you plant shrubs now, be sure to water it well for the next three months. Before planting soak the root ball overnight in a tub of water. If the plant is in a pot, make sure it is watered thoroughly before removing it from the pot. A dry plant may lose most of the dirt around its roots and it is way too late for bare root planting. Place water in the hole before planting and let it drain before setting the plant. Add half of the soil and water again to settle the soil and help remove air holes. Then fill the hole with soil and water again.
  • chard Sow second plantings of beets, carrots, and radishes, if you haven’t already. Plant broccoli, bush beans, chard, Chinese cabbage, kholrabi, sugar pod or snow peas and turnips for fall harvest.
  • For bigger mums, feed every three weeks.  This will ensure more flowers, until buds start to show color. When the blooms open feed weekly. A good 5-10-10 liquid fertilizer is a good choice.
  • Mulch to conserve soil moisture by spreading a three to four inch layer of organic mulch around the root zones of shrubs.
  • Water perennials in the early morning hours before noon. This gives the plants time to dry out reducing the risk of powdery mildew and other fungi. Lawns can be watered in the evening.
  • canadian thistle Be sure to remove thistles before they set seeds. Keep after all weeds.
  • In our area, you still need to be aware of slugs. Unless we are having a hot dry spell they will be out and about in the cool damp evenings and early mornings.
