The State Fair is going on. The nights are getting cooler even after the heatwaves we’ve had. Our gardens are producing, but we can say that the plants are changing. However, there is still a lot of gardening to do!

Harvest your own vegetables and fruits

Tart and tannic When fresh, aronia berries can be made into juice, jellies and jams, and are high in antioxidants. The plant provides white spring flowers that benefit bees and other pollinators.

Keep pulling out peppers, tomatoes, kale, herbs, cakes, squash, cherries, raspberries, strawberries, apples, pears, and whatever else you have left.

Think about how to keep your crop safe. We have a lot of information about her Preserve and prepare food safely.

Water trees and shrubs

Especially evergreen. We water faithfully during dry summers but may slow down a bit as the season comes to a close and we get busy with the start of school, the state fair, and end-of-summer fun.

Stop pruning and fertilizing trees and shrubs

Pruning stimulates new growth where you make the cut. Fertilizing will also encourage the plant to produce new growth. This new growth will not harden off before the cold weather arrives and will die.

Deadhead perennials

Removing spent flowers from plants such as yarrow and bee balm can cause the flowers to flow again. Although it’s not as prolific as the initial bloom, it’s always nice to get that extra bit of color that also feeds pollinators late in the season.

Replace spent annuals with fall mums

Containers may be on the decline now. Replace annuals that have finished blooming with the classic fall flower – mums.

Ornamental cabbage is also attractive in containers and in areas of the garden where your annuals finish off the summer.

There is still time to plant

Visit your local garden center for deals on hardy perennials, trees and shrubs and get them into the ground right away. Planting of perennials can continue until early September. It is also possible to plant trees and shrubs.

Make sure to water these new plants daily (depending on the rain) and cover them with a mulch. sawdust It protects plant roots from damage, retains soil moisture, and moderates soil temperatures so your plants can gradually move into winter.
