Using row covers or cold frames can extend your growing season by protecting these plants from unexpected frost.

5. Begin Planting Edible Perennials

Adding edible perennials to your garden provides reliable crops year after year. Consider planting:

Asparagus
Daylilies
Jerusalem artichokes
Rhubarb
Berry canes and bushes
Fruit and nut trees

These plants require less maintenance and enhance soil quality while extending your growing season.

6. Start Making Leaf Mold

Autumn leaves can be beneficial for soil health. Instead of disposing of them, consider creating leaf mold, which can enrich your soil. Here’s how:

Rake up fallen leaves.
Store them in a designated area.
Allow them to decompose over time to create nutrient-rich leaf mold.

7. Tidy Up Your Garden

Take some time to clean up your garden. Pull out overgrown weeds and remove any diseased plants. It’s also a good time to deadhead blooms and prune back perennials.

Bearded irises
Bee balm
Catmint
Daylilies
Lavender

8. Plant a Cover Crop

Cover crops are excellent for improving soil health. You can plant:

Fava beans
Oats
Clovers
Hairy vetch
Annual ryegrass
Winter rye

These crops will add nutrients back into the soil while preventing erosion over the winter months.

9. Divide Perennials

September is a great time for dividing perennials. This process creates more space for growth and prevents overcrowding. You can also benefit by having extra plants to share or sell.

10. Keep an Eye Out for the First Frost

Awareness of the first expected frost is crucial. Be prepared with row covers or other frost protection methods to safeguard your plants. If frost threatens your crops, consider preserving any unharvested produce.

Conclusion

September is a pivotal month for any gardener, filled with essential tasks that set the stage for the coming seasons. By continuing to harvest, preserving your bounty, planting for the future, and preparing your garden, you can ensure a thriving outdoor space. Embrace the beauty of autumn while making the most of your gardening efforts!
