13 Quick Growing Vegetables for Your Fall Garden

Instead of watching your summer crops struggle to ripen the last few fruits, pull them out and plant some of these quick growing vegetables for your fall garden.

The vegetable garden shines in summer with abundant harvests. As fall approaches, most of the summer crops begin to wind down. Cooler nighttime temperatures and diminishing sunlight takes its toll.

The heat loving plants respond by slowly reducing their growth. They struggle to produce that final fruit or vegetable; they devote all their energy to growing and ripening it. The foliage often times shows signs of stress, insect damage, and disease as the plants attempt to give up its final offerings.

You can keep the garden producing healthy crops well into fall by replacing your struggling summer plants with some quick maturing vegetables that thrive in the cooler weather and lower daylight hours of autumn.

Fall Vegetable Garden Planting Tips

Temperatures can fluctuate wildly at the end of summer. Days are often hot, but nights can be much cooler. Germinating seeds in hot weather can be difficult. Warm temperatures may prevent seeds from sprouting, and hot weather will dry out the soil quickly. As the season cools down, there is also the danger of a dip in nighttime temperatures and an early fall frost.

Here are some tips to deal with the challenges of a fall vegetable garden:

Choosing the Right Crops

There are plenty of cool-season crops that thrive in autumn. Use your first expected frost date as a guide (look yours up by zip code here: PlantMaps.com), and select cool season crops with short days to maturity for your fall garden.

Check the seed package for the average days to harvest and add a week or two to account for the decreased autumn daylight. Many leafy greens will mature within 60 days. These can also be harvested earlier at baby stage for a delicate and delicious salad or an addition to homemade soups.

Starting Seeds in Hot Weather

Some seeds are difficult to sprout when the weather is too hot. For example, lettuce and spinach won’t germinate when the soil temperature is over 75˚F. The soil temperature will be cooler than the air temperature. A probe type soil thermometer will give you an accurate reading.

If the weather is still hot, consider starting seedlings under lights indoors. Once the weather cools, harden off your seedlings, and transplant into the garden.

Providing Proper Moisture

Garden soil dries out much quicker in hot weather making it difficult to maintain the moisture level that seeds need to germinate and young plants to become established.

Pre-sprouting or soaking seeds ahead of time allow the seed to absorb enough moisture to trigger it to sprout. Once the seed germinates, it can be planted directly into the garden.

• How to Pre-Sprout Seeds

After planting seeds, water the well and keep the soil evenly moist until the seedlings emerge and become established. Once the plants begin to grow, let the soil dry slightly in between watering.

If you are planting fall transplants, water them well in hot weather and provide some shade until the young plants become established, and then water when the soil is dry a few inches below the surface. Mulch to help conserve moisture. As the weather cools, your plants should take off.

How to Deal with Early Frosts

Most cool-season crops can withstand a few light frosts once they are established, but young plants and newly emerged seedlings may be vulnerable.

Watch the weather and be prepared to cover young seedling if the weather dips to freezing temperatures overnight. With some protection during cool nights, most fall crops will continue to grow and produce well into early winter.
