The soil is relatively warm and moist this week, allowing the roots to settle in well. This makes it a good time to safely move (evergreen) shrubs . For example, you can transplant most butterfly bushes between now and November.

Tip!

Cut back wilted flowers from shrub and climbing roses. If there are no buds left, cut back the flower stem by half. Save the remaining pruning for later in the year.

Prune honeysuckle to encourage a beautiful branch system that will produce new flowers. Be careful, though: never cut away all the new growth from the summer, or you'll have no flowers next year.

Are your pumpkins almost ready to harvest? Check the stem carefully to see if it's still alive. Only harvest when the stem is completely corky on the outside. Cut or trim the stem from the plant, leaving a few centimeters attached to the pumpkin. Avoid making cuts as much as possible, as this will shorten the pumpkin's shelf life.

Tip: Place a stone or piece of wood under ripening pumpkins to prevent them from rotting before you can harvest them.

Swiss chard in a vegetable garden

Prevent Swiss chard and spinach from bolting by not letting them dry out. The lower nighttime temperatures encourage flowering, but the plants need extra watering to get through this period. If you see the center stem starting to flower, cut it out immediately and water the plant again. New leaves will then emerge.

Make sure your houseplants are in the best spot. Plants with thick, fleshy leaves like direct sunlight. Thinner-leaved varieties, such as the peace lily, prefer filtered light. Plants that wilt quickly and require a lot of water do better in a cooler spot.

Leaves are falling early this year due to the drought. Collect leaves from your paths in a leaf cage or garbage bag to make leaf mold . And put netting over your pond to prevent all those leaves from falling into the water and rotting.
