September in the Garden

September marks the end of summer and the beginning of autumn. There are many leafy greens you can plant in September, but there are also certain garden chores that must be done in order to ensure a healthy garden come spring.

First, it is important to start preparing the garden for the cooler months ahead. This includes clearing dead leaves and plants, pruning any overgrown shrubs and trees, and removing weeds.

Second, it is time to fertilize the soil in order to provide essential nutrients to plants. This can be done by applying a balanced fertilizer, such as a 10-10-10 blend.

Third, it is important to aerate the soil to provide plants with oxygen and help their roots to penetrate the soil. This can be done by using a digging fork to loosen the soil.

Fourth, it is important to winterize garden tools in order to keep them in good condition. This includes sharpening blades, lubricating moving parts, and cleaning tools.

Finally, it is important to mulch the garden to protect plants from cold weather. This can be done by adding a layer of organic material, such as leaves or compost, around the base of plants.
