Late summer is not the time to give up on the garden – it’s the time to lean in. The crops you plant now, with a little soil prep and the right seeds, can carry you from late August all the way through fall. And the secret to a strong second season starts right at the roots.
By August, garden beds have been working hard for months. Repeated watering, heat and a full season of harvests strip nutrients from the soil, compact its structure and break down its organic matter. Before you plant your next round of crops, it pays to amend and restore what you are working with.
What to Plant in Late Summer
Mid-July through August is the ideal window for getting cool-season crops in the ground. These plants thrive as temperatures begin to ease and actually produce better flavor after a light frost. Here is what to focus on right now.
Leafy Greens
Kale, spinach and lettuce are among the best performers in the fall garden. They are fast-growing and cold-tolerant and can be harvested repeatedly throughout the season.
- Kale: Direct-sow 6 to 8 weeks before your first expected frost. One of the most cold-hardy vegetables you can grow, it only gets sweeter after a frost.
- Spinach: Quick to germinate and productive in cool conditions. Succession plant every two weeks for a continuous harvest well into fall.
- Lettuce: Loose-leaf varieties do especially well when planted in late summer. Provide partial shade during the last warm weeks to prevent bolting.
Pumpkins and Summer Squash
Early August is the last call for planting pumpkins if you want them ready for fall. Most varieties need 90 to 120 days to mature, so timing is everything. Summer squash like zucchini are a faster option, typically reaching harvest in 50 to 60 days, and can still produce generously from a late-summer planting.
- Pumpkins: Plant seeds or starts immediately and choose a compact variety if space is limited. Amend with mushroom compost before planting since pumpkins are heavy feeders.
- Summer Squash: Direct-sow for a late harvest. Rich, well-amended soil improves both yield and flavor, making the mushroom compost especially valuable here.
How to Protect and Maintain Late-Season Beds
Once fall crops are in the ground, a little consistent attention goes a long way toward a productive harvest.
- Water wisely. Fall crops generally need less water than summer plantings, but consistent moisture is still critical during germination and early growth. Water in the morning to reduce evaporation and lower the risk of fungal issues.
- Watch for pests. Aphids and caterpillars can be especially active in late summer. Inspect plants regularly and address problems early. Row covers can help protect leafy greens from insects while still allowing sunlight and water through.
- Know your frost dates. Understanding your first expected frost date helps you time plantings correctly and know when to harvest. Check your seed packets for days to maturity, then count backward from your local frost date to find the ideal planting window.
How to Amend Your Beds Before Planting
A simple bed refresh before fall planting sets the tone for the season. Here is a step-by-step process to get your beds ready.
- Clear spent plants. Remove finished summer crops and debris from beds to reduce disease and pest carryover into the fall season.
- Loosen compacted soil. Use a hand cultivator to break up the top six inches of soil, improving drainage and root penetration.
- Apply compost. Spread a 2- to 3-inch layer over the bed and work it in with a trowel or cultivator.
- Water thoroughly. After amending, give beds a deep soak before planting. This activates the compost and settles the soil around new roots.
- Mulch around transplants. Add a light layer of mulch to retain moisture as temperatures fluctuate between warm days and cooler nights.
A hand cultivator loosens compacted soil before amending, while a sturdy garden trowel helps mix compost evenly into beds and set transplants at the right depth. Both are reusable tools that serve you season after season.
The Right Compost Makes the Difference
