Yes, believe it or not – there is still time to grow some delicious fall vegetable crops in your garden. Especially if you are a big fan of salads!

Although summer is fading fast, and September is knocking on the door, there are still enough growing days remaining in most growing regions to plant and harvest a few fall vegetable crops.

Here are 5 great selections that need just 30 days or less of frost-free weather to harvest

5 Fall Vegetable Crops That Can Be Grown In 30 Days


Lettuce is a great choice when it comes to growing fall vegetable crops. The cool, crisp autumn weather is ideal for growing all types of loose leaf greens.

Many varieties, from baby leaf, to bib and mesclun can be  harvested in as little at 21 days.

Lettuce is a fast grower that thrives in the cool fall weather

Even better, they can be harvested multiple times. So if autumn’s warmer temperatures extend a few extra weeks, you can have fresh salads deep into the year.

Lettuce performs best in loose, well drained and fertile soil. To spur fast growth, mix in plenty of compost to recharge the soil from crops grown over the summer.

Nothing beats the taste of tender young spinach! This nutrient-filled super food loves the chill of fall.

Sow spinach seeds directly into the soil up to 3 weeks before your last frost date. Plant seeds 1/4″ to deep, spacing 2 inches apart. Baby spinach leaves can be harvested at about 2″ for maximum flavor. You can usually start to harvest by the 21 to 28 day mark.

Spinach holds up well against light frost, but  be sure to harvest plants if a hard freeze is forecast. Once hit with temps well below freezing, the tender leaves will wilt in the garden.  Seed Link : Butterfly Heirloom Spinach Seeds

Radishes grow fast, They are ready for harvest in about 28 days

When it comes to fast growers, radishes top the list. That makes them ideal for a late season planting. Some varieties will go from seed to harvest in as little as 25 to 28 days. Most can be fully harvested at the 30 to 40 day mark.

Sow seeds directly into the soil, leaving a few inches between seeds. Radishes need a steady supply of moisture to grow well, so water seedlings often. They also benefit greatly from added compost. Seed Link : Early Scarlet Radish Seed


Kale, like spinach, actually thrives in cool weather. It is truly the ultimate super-food, and is loaded with vitamins and minerals. Varieties such as Red Russian can be harvested as baby leaves in as little as 25 days.

Kale seeds will germinate fast in the warmer soil of fall. Plant seeds a 1/4″ deep, and water well. Harvest as baby leaves as soon as the foliage reaches 2″ or more.

Arugula is another cool-weather lover. It can tolerate even mild frosts and keep right on growing. The spicy leaves are perfect for adding a little zing to fresh salads.

Arugula grow best in loose, fertile, and well-drained soil. Plant seeds 1/4″ deep, allowing about one inch between seeds. Be sure to add in plenty of compost for added soil nutrients. In addition to compost, another great soil energizing option is worm castings, which can really power plants that need a late-season push.

With most varieties, arugula can go from planting to harvest in around 28 days.  Seed Link : Heirloom Arugula Seed
