🍂 What to Plant in September 2026 — Part 1: Vegetables & Herbs to Grow Now

🌱 Quick Answer

September is a great time to plant cool-season vegetables such as lettuce, spinach, radishes, kale, carrots, and arugula in many regions. Your exact planting window depends on your local climate and average first frost date.

🥬 What Vegetables Can You Plant in September?

As summer crops begin to slow down, cooler temperatures create a second opportunity to grow fresh vegetables.

The easiest choices are crops that either mature quickly or tolerate cooler weather.

🥗 1. Lettuce

Leaf lettuce is one of the easiest September crops.

🌤️ Cooler days reduce heat stress, and baby leaves can be harvested before plants reach full maturity.

⭐ Best for small spaces

🥬 5. Kale

Kale is one of the most reliable fall crops.

❄️ It tolerates cooler temperatures better than many summer vegetables and can continue producing well into fall.

In areas with a short growing season, transplants may be better than seeds.

🌿 What Herbs Can You Plant in September?

Depending on your climate, September can also be a good time to refresh your herb garden.

Consider:

• 🌿 Cilantro
• 🌱 Parsley
• 🌱 Chives
• 🌿 Dill

Cilantro especially appreciates cooler weather and often performs better in fall than during hot summer months.

📅 How Do You Know If It’s Too Late to Plant?

Check two things:

1. Your average first frost date
2. The plant’s days to maturity

🧮 If a vegetable needs 40 days to mature and your first frost is expected in 60 days, you likely still have a reasonable growing window.

Always allow extra time because plants grow more slowly as daylight decreases.
