Understanding August Planting

Importance of August Planting

Planting in August is essential to keeping your garden thriving and colorful through the fall season. By choosing the right plants, you can ensure that your garden continues to produce vegetables, and your flower beds remain beautiful as summer fades into cooler temperatures.

Additionally, August planting helps to fill those gaps in your garden created by spent plants and ensures a continuous harvest for your family.

Preparing for Fall Garden

To prepare your garden for fall, you should start by cleaning up any debris, dead leaves, or spent plants from your garden beds. This will help prevent the spread of diseases and pests and provide a clean environment for your new plants.

Make sure to amend your soil by adding organic compost or aged manure to enrich it and help feed your plants throughout their growth. This will give your new additions the nutrients they need to thrive through fall.

Finally, consider your garden’s layout and plan accordingly. Keep in mind both the mature size of your plants as well as their sunlight requirements when deciding where to place them.

This will ensure they have adequate room to grow and receive the proper amount of sun throughout the day.
