What I've sown for fall and winter edibles

"Well used" self watering pot I started my lettuce seeds in
Sunday, September 8, 2024

I started a variety of seeds yesterday for harvesting all fall and winter.  With a portable greenhouse, you can keep the Midwest lettuce salads going all the way to next spring.  This fall, my sowings are for lettuce, arugula, snow peas, chard, leaf mustards, chards, kales, pink dandelion, and pink celery.

The challenge to starting cool season lovers from seed this time of year is that it can be so hot.  The seeds will not germinate well in ground temps above 70 degrees F.  There are a couple of options for summer time seeding.  You can grow in shade, cover with a shade cloth or start your seedlings indoors move outdoors after they have sprouted.  Right now, it is cool with the highs in the upper 70's and lows in the mid 60's so perfect temperatures for lettuce germination.  Outdoor seed starting tips
I like to start in rectangular, self watering pots on our covered patio, close to the watering can on the northeast side of the house. Most of what I have sown will be up in 7 days if kept well watered.  I let them grow until they have the first set of true leaves and are about 2” tall.  I then transplant them into their permanent home, keeping them well watered for another couple of weeks.  The trick this time of year to planting is getting the plants close to full size by November when daylight hours are too short to support growing.

Here is what I planted.  Be sure to label your seed rows!
-Winter Density-a romaine type that is full size in 54 days
-Tango-a leaf lettuce that is frilly and light green, full size in 45 days
Landis Winter-a butterhead lettuce that reaches full size in 50 days
North Pole-another butterhead lettuce that is full size in 50 days
Tom Thumb-a small romaine type that is full size in 50 days
Winter Crop-a headed lettuce so approximately 50-60 days
Winterwunder-a loose leaf that is full size in 60 days
Red Romaine-a romaine that is full size in 40 day
Provencal Winter mix-a variety of greens
Arctic Tundra mix-a variety of greens
Roquette Arugula-full size in 42 days
Pink Dandelion-full size in 85 days
Pink Celery-full size in 60 days
Avalanche Snow Pea-30" vine, 61 days to harvest
Oregon Sugar Pod II Snow Pea-28" vine, 60 days to harvest
Little Purple Snow Pea-27" vine, 50 days to harvest

All of these will have leaves that are harvestable in about half the number of days to get to full size.  On the flip side, it generally takes longer for fall crops to get to full size than the packet says as the temperatures are getting cooler and the daylight shorter going into fall than in spring time.  A rule of thumb is 2 weeks longer to full size.

I like self watering pots because you can fill the reservoir without directly watering the soil surface.  With lettuce the seeds take light to germinate so they are very close to the surface.  Watering the soil itself can dislodge the seeds and move them all around the pot.  This isn't a catastrophe if you have all the same type planted in a pot, but since I have 8 varieties in the same pot, I don't want them moving around so I can see what germinates and how well they do through the season.  

You can start your seeds in any container you prefer.  If you do a coir or peat pot, you can just plant the entire thing in the garden bed after the seedling is up and going strong.  The drawback is that they have to be watered more as so much moisture wicks out of the permeable pot.

 

For this round, I watered the soil well, then planted the seeds, labelling each mini row in my rectangular pots that I start seeds in.  I will continue misting the top to keep the soil moist and filling the reservoir from the bottom.  You don't want the soil to dry out before the seeds have germinated.

After the seedlings are up, I'll wait until they have a few leaves and are about 2" or so tall before transplanting into larger pots for the winter.  I cover all my larger self watering pots later in the season with a portable greenhouse to keep the greens going all winter.  How to extend the garden season

If you want to direct seed in your mulched flower bed, dig a shallow trench about a quarter inch deep, fill with potting soil, seed, pat down, then cover lightly with more potting soil.  Water well with a gentle stream of water so you don’t wash the seed away.  I use a rain head on my watering can.  Even better is to get the soil moist, then scatter the seeds, cover lightly with potting soil and pat gently.  Growing fabulous lettuce and greens 

A  I also have purple sprouting broccoli, Ruby Streaks mustard, Giant Blue Feather lettuce, chard, Utah celery and Hilton Chinese Cabbage that has self-seeded.  I should have plenty of greens for salads all the way through winter with covering my self-watering pots over these winter hardy plants.
