July Garden Tips: There’s lots to do in your garden In June, now that Summer is here!
- Watch for the Japanese beetle on your Asiatic Lilies, Roses, Rose of Sharon, Dahlias, Hollyhocks, and numerous other plants. Handpicking and squeezing, combined with a beetle trap, are the most efficient ways to limit these ravaging critters. Luckily, the little red devils don’t eat Day Lilies (Hemerocallis)
- Watch for earwigs and Gypsy moth caterpillars. Spray plants with a 40:1 mixture of water and dish soap.
- Ants can also be a problem. The ant powder does not seem to work for me. Maybe the ants didn’t read the instructions to take it back to their nest.
- Trim evergreens, cedar hedges, etc., NOW as needed, not later in the summer.
- Stake straggly annuals and perennials, or pinch them back to promote new growth and make them bushy and probably re-bloom.
- Raise lawn mower blades for summer mowing. Grass should be at least 5 - 7.5 cm (2 to 3 inches) high to stay healthy and weed free.
- Prune spring flowering shrubs like Forsythia and Spirea after blooming. If you really want to be picky, remove individual spent lilac blooms.
- Water flower beds deeply and try a second round of weeding. Add mulch again to keep the weeds at bay.
- Mulch your tomato plants. When a ripe tomato drops, it won’t split or get muddy. Mulch holds moisture in too!
- Thin, hoe, weed and water vegetables as required. (This is why I stick to flowers)
- While there has been lots of rain, water lawns and beds as deeply as you can.
- Tackle weeds now before they go to seed. Save yourself from weeding their offspring next year.
- Stake tall perennials that may be weakened by too rapid growth or too much rain.
- Turn your compost pile regularly and keep it moist - not too wet, not too dry - just right, like Goldilocks.
