By August, many New Mexico gardens are looking a little tired. Tomatoes are sprawling, squash plants are taking over, and the summer heat has tested both gardeners and plants. But August is not the end of the growing season. It is the beginning of one of my favorite planting windows.
A fall garden feels different from a spring garden. The pace is calmer, the weeds are less aggressive, and cooler nights make it much more pleasant to be outside. These are the vegetables I reach for first when I start planting again.
🌱 Radishes are the instant-gratification crop of the fall garden. Many varieties are ready in less than a month, making them perfect for tucking into small spaces. Sow a short row every week or two instead of planting the entire packet at once, and you can keep harvesting crisp radishes for weeks.
🥬 Lettuce is another easy favorite. Loose-leaf varieties mature quickly and can be harvested one leaf at a time. I like to plant several colors and textures together for a garden bed that is almost too pretty to eat. Give young seedlings a little afternoon shade while temperatures are still high.
🌿 Spinach is worth planting even though it can be slow to germinate in warm soil. Keep the seedbed consistently moist, and consider waiting until later in August if the weather is especially hot. Once established, spinach loves cool fall temperatures and rewards you with tender leaves for salads, sandwiches, and sautés.
🥕 Carrots require patience, but homegrown carrots are hard to beat. The most important step is keeping the top layer of soil moist while the tiny seeds germinate. A light covering of compost or a board placed over the row for a few days can help prevent the surface from drying out.
❤️ Beets are one of the best two-for-one crops. You can eat both the roots and the tender greens. Thin seedlings early, then use the young leaves in salads instead of tossing them.
🥬 Kale is dependable, productive, and often tastes sweeter after cold weather arrives. Baby kale can be harvested quickly, while mature plants may continue producing well into winter with some protection.
🥦 Broccoli takes more time, so I prefer planting healthy transplants rather than starting from seed in August. Give each plant enough room, keep an eye out for cabbage worms, and be patient. A fresh broccoli head from your own garden is worth the wait.
Before planting, give beds that have worked hard all summer a little attention:
♻️ Recharge existing beds with a layer of finished compost.
🌱 Fill new raised beds with a well-draining garden soil rich in organic matter.
🍂 Add mulch once seedlings are established to conserve moisture and soften temperature swings.
💧 Water consistently, especially while seeds are germinating and young plants are becoming established.
Then plant a few favorites and let the coming cooler weather do some of the work.
August may feel like late summer, but in the garden, it can also feel like a fresh start.
For me, that second chance is one of the best rewards of gardening in New Mexico, season after season.
