September Gardening Calendar
Wondering What You Should Be Doing In Your Garden?
Below is a calendar of key things you can be doing in your garden during the month of September.
Approximate Timing & September Gardening Activities
Early September:
- Time to plant early fall vegetables this week, such as tomatoes, peppers, zucchini and more...
- Pull summer flowers and begin planting fall flowers—many varieties in-store now!
- Use insect preventatives in early flowers and vegetables.
- If you’re using a non-organic fertilizer, now’s the time for your fall application! An easy way to remember: mark your calendar for Valentine’s Day, Memorial Day, and Labor Day—three key dates for fertilizing.
- If you’re planning to plant a winter lawn, you don’t need to fertilize this month. However, if you’re not planting a winter lawn and want to keep your grass green through fall and winter, be sure to fertilize both this month and next.
Mid-September:
- Now's the time to plant iris starts and garlic bulbs.
- Plant saffron crocus bulbs for a late fall harvest.
- It's time to fertilize* your citrus.
- It's a great time to plant citrus!
Late September:

- Plant select seeds indoors for your fall/winter Tasty Garden.
* = Fertilize once temperatures are below 90° F. However, you can still support your plants during heatwaves with vital nutrients.
