Gardening Tasks by Month for Kincardine, ON

Fertilize roses (last time this year).
Order spring-blooming bulbs at the end of the month for fall planting.
Two or three leaves should be left when cutting gladiolus, so that the bulbs can ripen.
During these warmer months, raise the mowing height to 2.5 to 3 inches.
Hardy lily bulbs may be planted in the ground and left to overwinter outdoors.
Plant fall-flowering bulbs now.
Check the mulch around your plants; if there is little or no mulch, make sure to put a 3- to 4-inch layer to conserve moisture.
Cut out raspberry and blackberry canes that have just finished fruiting.
Keep weeding your garden so that the weeds do not compete with your plants for water and nutrients.
Be sure to regularly water your houseplants and potted plants. Use a water-soluble fertilizer so that the plants do not lose vital nutrients. Do not let houseplants dry out.
Separate melons from the ground with a thin board to prevent decay or damage from wireworms.
Japanese beetles? Handpick and drop in a jar of detergent and water.
Remove dead pea vines, bolted lettuce, and other plants that have gone by and add them to the compost pile. If they show signs of disease, however, burn them.
Lawns or bare spots reseeded with grass now will have a chance to get established before winter sets in. Water often and mulch with hay.
Do not neglect your plants in hanging baskets; they dry out faster than those in the ground.
Mid-August through September is a good time to transplant any shrubs that you’ve purchased with root balls wrapped in burlap. Make sure you get them in the ground two to three days after purchase. Do not fertilize until the second year, when the feeding roots have become established.
Make sure that potatoes are not escaping into the sunlight. Hill or mulch them if they are.
Prune only to retain the shape. Do not prune spring-flowering shrubs such as azaleas and rhododendrons. Do not prune trees.
Maximum flavor of herbs for drying is achieved by cutting them just before their flowers open.
Compost should be watered during dry periods so that it remains active.
The vegetable garden is likely to require daily harvesting now. Cucumbers, squash, tomatoes, eggplant, and peppers should be picked as soon as the fruits are ready. This not only captures the best flavor, but it also makes way for new fruits.
Tomato hornworms? Handpick and drown in soapy water or snip in half. Control the smaller worms with B.t. (Bacillus thuringiensis), a biological control.
If you notice a gap in your perennial bed between spring and fall blooms, visit a local nursery to see what’s in bloom there and ask the experts for advice on what to plant.
This is a great time to plant new perennials, shrubs, and trees, especially evergreens; they have a better chance to establish themselves during the milder fall months than those planted in the spring.
Lift, divide, and replant Japanese and Siberian irises soon after bloom. Transplant them to places where they will have “wet feet but dry knees.”
There’s still time to plant fall crops of beans, beets, broccoli, carrots, Chinese cabbage, kale, lettuce, and peas.
Cut back the flower stalks of perennials that have finished blooming. Cut delphinium flower stalks to the ground, and a new, though smaller, flower stalk will develop. The flower will survive the coming cold days and even light frosts.
If there are dry spells, remember to water your plants and shrubs thoroughly to prevent drought damage.
Dig up your potatoes once the vines have died and the tops turn brown.
Remove any old plants that have stopped producing to help eliminate insects and diseases from your garden.
Sow these perennials outdoors for next spring: aquilegia, Phlox paniculata, digitalis, centaurea, and primrose.
Dig up and divide daylilies that have finished blooming.
Ripen tomatoes on the vine, not the windowsill; put fallen green tomatoes in a brown paper bag with an apple.
Remove any dead flowers from plants to encourage new growth.
