Starting Seeds Indoors for the Fall Garden
It might feel like summer outside, but in hot climates like Zone 9a, fall garden prep starts now. When temperatures are still too high to plant directly in the soil, starting seeds indoors gives your fall crops a strong head start. Whether you're growing leafy greens, brassicas, or root veggies, getting those seeds going indoors means you’ll be ready to transplant as soon as the weather breaks.
Here’s how I start fall seeds indoors without fancy equipment just practical tools and a little planning.

Instructions:
Prep your containers by filling them with moist seed starting mix. Don’t pack it down—keep it light so roots can grow freely.
Plant your seeds according to depth instructions on the packet. In general, smaller seeds sit closer to the surface.
Label each tray or row to avoid mystery plants later.
Water gently using a spray bottle or bottom watering tray to avoid disturbing the soil.
Provide light—at least 12–16 hours a day. A south-facing window works, or use a basic grow light setup.
Keep the mix moist but not soggy. Check daily.
Harden off your seedlings before transplanting by gradually introducing them to outdoor conditions once temps begin to cool.
Tips & Tricks:
Choose varieties suited to your zone’s first frost date—many greens and brassicas thrive in cooler weather.
Start more than you need—some may not germinate or thrive.
Reuse plastic clamshell containers or paper pots to avoid buying new trays.
Fall gardening in hot zones is all about timing. By starting indoors now, you give your plants the head start they need to thrive when cooler days arrive. It’s a small effort now for a big harvest later—and one more way to keep your garden producing year-round.
