Growing, Storing, & Using Fall Radishes

With the official start of fall just a day away, planting in the garden is really winding down here in the mid-Atlantic. Both the cool weather and dwindling hours of daylight mean that plants require more time to get established and grow to harvest. One quick crop you can still sneak in is radishes.

Great Fall Varieties

Here are a few varieties you can sow this time of year in the Mid-Atlantic and Southeastern United States.

Miyashige White Fall Daikon Radish

Juicy and flavorful, this variety is usually harvested when 12 in. long and 2-3 in. in diameter, though it will grow much larger!

Deep-Till Radish

Great for no-till systems and breaking up compacted soil!

Misato Rose Fall Radish

This is our favorite fall radish and is very forgiving. It will still bulb up even if it’s crowded or thinned late.

Red Head (Roodkopje) Radish

Sneak this quick-growing variety in this fall. It’s ready to harvest in just 25 days.

How to Grow Fall Radishes

Most fall type radishes do best in cold weather but you don’t want to wait too long to sow them. We recommend sowing them 5-10 weeks before your first fall frost date. Sow seeds, 3/4” apart, 1/2” deep in rows 8-12” apart. Fall radishes should be thinned to wider spacing than spring radishes about 4-6” apart.

When to Harvest  

You can begin harvesting radishes as soon as you’re happy with their size and incorporate them into salads and other dishes. You should harvest all of your radishes before temperatures dip below 20°F. If you live in a place with a mild winter you can leave radishes in the ground and harvest them as needed. 

The exact size your radishes reach will depend upon how early you plant and the variety of radish you select.

Storing Radishes

Radishes can be stored in a root cellar or the crisper drawer of your fridge. They can be stored for 2-3 months.

Gently brush off excess dirt and trim the tops off. If you’re storing them in the fridge, wrapping them in a damp cloth can help keep them good for longer. If you’re storing them in a root cellar, bury them in totes of damp sand. It’s easiest to do one layer at a time and make sure the radishes aren’t touching each other.

Ways to Use Radishes

Radishes are incredibly versatile root crops that are an excellent choice for the fall garden. They can be added to a variety of dishes through the early winter.

  • Use them as a cover crop to break up hard-packed soil.
  • Grate them and add them to kimchi.
  • Pickle them. 
  • Make radish leave pesto
  • Roast them with a bit of olive oil, seasoning, and other root veggies.
  • Add them to fresh salads.
  • Grate them up for spring rolls and wraps.
  • Sauté the tops as you would other greens.

Harvesting Sunflower Seeds & History

If you grow sunflowers the garden looks a little extra magical this time of year! There’s just something special about these big flowers that follow the sun. Today, they are a popular crop for home gardeners and rank among the world’s most important oil crops but they’ve got a really long and interesting past too.

Domestication

Sunflowers were first cultivated by Native Americans. Some archeologists believe that they may have been grown in what’s now Arizona and New Mexico as early as 3000 BC. The seeds were an important food source and were used in a variety of ways including for grinding into flour, mixing with other vegetables, and squeezing for oil.

Sometimes sunflowers like the Hopi Dye Sunflower were also used to create dye for textiles, baskets, and body painting. They were also used medicinally and the stalks were sometimes utilized as building materials. 

To Europe and Back

When Europeans came to America they quickly brought the sunflower back to Europe (probably around 1500). It was primarily grown as an ornamental until it became popular in Russia as an oil crop. During the early 1800s, it was commercially cultivated in Russia with more than 2 million acres planted each year and new varieties being bred.  

Some of these new varieties like Mammoth made their way back to the United States to be featured in seed catalogs by 1880 and are still around today. They were most likely brought to the U.S. by Russian immigrants. In the early 1900s, sunflowers quickly gained popularity as oil and silage (animal feed) crops in the United States and Canada along with their ornamental use in the home garden.

Eating Sunflowers

As the title of this post suggests, sunflowers are a wonderful edible flower. It’s not just their seeds that are edible either. Very young plants as well as sunflower sprouts are excellent in salads and wraps. The flower petals, though they can be a bit bitter can also be used sparingly in salads to brighten things up or as natural decorations for cakes. 

The leaves and stalk can also be eaten. When harvested young and peeled the stalk is a bit like celery. The leaves should be steamed or cooked like other greens before eating to destroy irritating hairs. Unopened flower buds can be cooked and used like artichokes.

Harvesting Sunflower Seeds

When to Harvest

Sunflowers are best harvested when they’ve fully matured. The plant’s foliage should be yellow and the back of the flower should be yellow or brown. The petals should have fallen off and the seeds should be plump and developed their dark or striped coloring. Harvesting too early when the plant is still alive and the seeds are light-colored will probably result in immature seed.

In order to get your sunflowers to mature this long, you may need to provide them with a bit of protection. They’re a favorite of birds, squirrels, and other small animals so you may need to wrap the flower heads in mesh or cover them with mesh bags to deter wildlife. Don’t use solid plastic bags. The material should be perforated or breathable or the flower head may rot.

Harvest

Cut the flower heads, leaving about 4-6 inches of stalk. Cover the flower heads with paper bags and hang them somewhere cool and dry for 1-2 weeks or until the seeds are fully dry and mature. They can also be laid out on screens if you have the space to set something up.

At this point, you can either separate the seeds or leave them on the head. Sunflowers can be hung outdoors for birds to enjoy through the winter or hung in your chicken coop for them to enjoy. 

Rub the seeds off the flower head and lay flat to dry for an additional day. Then they can be stored in airtight containers out of direct sunlight. They’re ready to plant next year or roast for a tasty snack!

Fall Lettuce Garden

One of my favorite things about fall is that the cool weather provides a second opportunity to grow lettuces. There are so many varieties to bring color, beauty, and flavor to your autumn garden and plate. Here are some tips for starting your own fall lettuce garden.

Varieties

Here are a few of our favorite varieties for fall plantings though many others will do well too.

Sowing

Lettuce germinates best when soil temperatures are 75°F or lower and thrives in cool weather when temperatures are in the 60°s. In areas where temperatures are still high during the early fall you may need to a few tricks to get lettuce growing well.

Waiting longer to plant isn’t always a great option because as the weather cools we lose daylight. Lettuce and other plants will take longer to mature during the fall as the light dwindles. 

One way to help provide your lettuce with cool temperatures is to mist the soil regularly, at least once a day. This helps keep it moist and cool, especially important while its germinating. You can also use a thin row cover or material like tulle to shade the soil a bit.

Alternatively, you can sow lettuce in trays in a cool room and transplant them later. Romaine, crisphead, and butterhead lettuces work well for this.

Lettuce can be sowed in rows or gently broadcasted. Generally, broadcasting works better for looseleaf and cut and come again lettuce mixes that will be harvested small. Broadcasting over the entire bed for these types of plantings can help block out weeds. If you want full heads of lettuce it’s typically easier to plant in rows so you can easily weed and ensure they have enough space to mature.

Thinning

No one likes thinning but it’s critical for healthy plants. As previously mentioned, looseleaf lettuces are better suited to tighter plantings however, it’s still best if they have some air circulation. Larger, heading lettuces need more space and should be thinned to 10-16 inches depending on the variety. If you wait to thin until plants are 1-2 inches tall, they make excellent baby salad greens.

Season Extension

There are a number of ways to keep your lettuce garden alive later into fall and even winter. Cold-frames and low tunnels are affordable, simple to set up options. Even tulle or light row cover like we mentioned above will provide some additional protection. Check out our post, Easy Season Extension for Fall for more ideas.

Lettuce will eventually stop growing as the hours of daylight dwindle but will still provide a nice supply of fresh greens. Small, young plants can be overwintered using these methods to provide an extra early spring crop. We had success overwintering Rouge d’Hiver under row cover here in Virginia.

Fall/Winter Care

While the rest of your garden may wind down as we continue into fall, your lettuce and other fall crops may still require some attention. Thankfully, there should be little pest or weed pressure but your lettuce will still need to be watered occasionally. This is especially true if you live in the Deep South or your area experiences additional warm, dry weather.

If you’re growing lettuce in a cold frame or high/low tunnel covered with plastic you’ll need to be sure to open or vent them on warm, sunny days. Temperatures can rise surprisingly quickly in a cold-frame and could kill lettuce plants.

Bring a little extra beauty and flavor to your garden this autumn with a fall lettuce garden. Show us your gardens on Facebook, we’d love to see how they turn out!
