Fall Garden Plan
Central Texas fall — September through November — is actually the best gardening season here. Gentler temperatures, fewer pests, longer harvest. But the fall garden starts in August, and this year we're expanding it.
The same heat that hammered our tomatoes in summer becomes our friend in fall. September through first freeze (late November) is typically a long, productive window for cool-season crops that would never survive Pflugerville summer. According to Texas A&M AgriLife, Travis County Extension, and Austin Organic Gardeners, this is when Central Texas gardeners traditionally see their best yields.
Estimated fall budget: $212-362 including this year's expansion — comfortable headroom inside ~$500. That figure is the total of the shopping table further down this page. (Costs are estimates, not quoted prices.)
🗓️ August: what to do right now
This is the part that surprised us. Travis County Extension's August advice is that this is when the fall garden actually starts — some things go in the ground now, and the crops we want in September need their seeds started indoors in August. Their guidance: plant the last round of green beans, cucumbers and squash late in the month using varieties that mature in 60 days or less, and start seeds for brassicas and Swiss chard indoors, where "seedlings will be transplant size in about 6 weeks."
| Now (first week of August) | What | Why now |
|---|---|---|
| 🫘 Southern peas — sow outside | Black-eyed type (California Blackeye #5, about 60 days) | A warm-season legume and our first real protein crop. AgriLife's fall planting date for our region is August 1, so this one is genuinely now-or-next-year. Black-eyed types handle our alkaline soil better than cream or crowder types. |
| 🎃 Butternut squash — sow outside | Waltham Butternut (95-100 days) | Winter squash goes in by about August 10 here. Sown in the first week it finishes in early-to-mid November, just ahead of our usual first freeze — so it's a plant-now crop, not a plant-later one. |
| 🥬 Napa cabbage — start seeds indoors | 'Bilko' (54 days) | Six weeks indoors puts transplants in the ground mid-September, which is right on AgriLife's cabbage date. This is the kimchi cabbage. |
| 🌱 Swiss chard — start seeds indoors | Bright Lights, Lucullus or Ruby | Frost-tolerant, cut-and-come-again, and it carries deep into winter. Probably the easiest new crop on this list. |
| 🌼 Fall flowers — late August | Fall bloomers, bluebonnet seed, nasturtium + marigold | Travis County recommends adding fall bloomers toward the end of the month and sowing wildflower seed, especially bluebonnets. Nasturtium and marigold go in alongside the squash — see the pest note below. |
What we're planting in September and after
| Crop | Plant when | Where | Why |
|---|---|---|---|
| 🌿 Cilantro | Direct seed mid-September | All-day-shade yard area | Bolts in heat; thrives Oct-March; partial shade favored |
| 🥬 Lettuce (leaf varieties) | Direct seed mid-September | Retired tomato grow bags + main bed | Black Seed Simpson or Salad Bowl; tolerates partial shade per AgriLife |
| 🥬 Spinach | Direct seed late September | Main bed after tomato fall flush ends | Cool-season; improved by light frost |
| 🥦 Broccoli | Transplants mid-September | Main bed corners | Heads ready Nov-January |
| 🟢 Snow peas | Direct seed mid-September | Climbing trellis (south side of cattle panel) | 8-10 weeks before first freeze per AgriLife |
| 🌰 Beets | Direct seed mid-September | Main bed | Quick (50-60 days) |
| 🌿 Parsley + chervil | Direct seed mid-September | Main bed companion slots | Refresh of the spring planting (which slowed in summer heat) |
| 🥔 Potatoes | Plant September | Grow bags | AgriLife's fall date for our region is September 1. Buy seed potatoes in August so they're on hand. |
| 🫛 Green beans | Direct seed early September (or very late August) | Main bed or bags | Use a 60-day-or-less variety so they beat the freeze. |
| 🥗 Arugula | Direct seed September | Shade area or bags | Fast, peppery, cut-and-come-again |
| 🥕 Carrots | Direct seed November — later than we first planned | Main bed | We had this down for mid-September, but AgriLife's average planting date for our region is November 10. Carrots are frost-tolerant, so the later sowing is fine — it just means a winter carrot, not a fall one. |
Squash attracts two different insects that are easy to confuse, and telling them apart decides what you do. Ohio State's guidance is a clean field test: squash bug eggs are "bronze-brown and are laid in neat clusters on the undersides of leaves," while squash vine borer eggs are "flat, reddish-brown, and laid singly at the base of stems or on nearby soil."
Butternut is a deliberately good choice here. Ohio State considers it resistant to the vine borer — moths rarely lay eggs on it — and a study from Oklahoma State found squash bugs prefer yellow straightneck and crookneck squash over butternut. Less preferred is not immune, though, so we still do the basics: check the undersides of leaves, and crush egg clusters early. Utah State treats a single egg cluster per plant as the point to act. Nasturtium and marigold planted alongside have been shown to reduce squash bug damage, which is why they're on the August list.
How the bed transitions
After first freeze takes the tomatoes (typically late November), we'll pull the plants, rake the existing mulch aside, add 2-3 inches of bagged compost, and replant the bed with cool-season crops. The cattle panel trellis stays — snow peas can climb the south side.
The basil will be done after first cold night. The parsley refresh planted in September will carry through the cool season. Marigolds will reseed themselves (often) or get pulled and replaced with cool-season companions.
Blackberries are perennial. All four plants — two Prime-Ark Freedom, one Ouachita and one Big Daddy — are established in their own 25-gallon grow bags, so no blackberry purchase is needed this fall. In late winter (January-February) we do dormant-season pruning: cut out spent floricanes after fruiting; tip-prune new primocanes. Mulch heavily before winter rains.
Fall shopping list (estimates)

On the list, but not yet
A few things we want are real crops with the wrong calendar, so they're waiting rather than dropped:
- Bell peppers — the transplant window for fall closes in late July / early August here. Next spring. Meanwhile the jalapeño keeps producing: Travis County notes peppers "love fall weather and will produce right up until frost."
- Onions — not a fall-planting crop for us at all. AgriLife's date for our region is November, and onions come with a separate household consideration we'll work through before then.
- Garbanzo (chickpeas) — a cool-season crop, and we could not find a Texas planting guide for it. Before we sow the seeds we already have, this one needs its own homework.
- A greenhouse or covered growing space — the honest answer to "can we have peppers all year?" We haven't researched it yet.
Year-2 planning notes
By January-February 2027, we'll have actual data from year 1:
- Soil pH readings from the spring planting tell us whether additional amendment is needed
- What worked vs what didn't — variety performance, pest pressure, watering rhythm
- Crop rotation: the tomato bed gets a year off from tomatoes — try beans or peppers there in 2027 to break disease/pest cycles. Tomatoes return year 3.
- Start earlier. The clearest lesson from this year: several things went in late because of the heat. Spring 2027 tomatoes can go in mid-March to early April (Pflugerville's typical first-tomato window is April 1-30, earlier than this year's late-May start).
The all-day-shade area
That spot in the yard that gets all-day shade is perfect for cool-season herbs that bolt in summer sun. Cilantro is the headline — direct seed in mid-September, harvest leaves October through March. Possible additions:
- Mint (contain it in a pot — it spreads aggressively if planted in ground)
- Chervil — delicate parsley-like herb, French cooking staple
- Sorrel — lemony leaves for salads + soups
- Garden cress — quick-growing peppery green
These can fold into the fall garden expansion as we get comfortable.
