Spring Vegetables

A Good Head Start

We installed a cold frame in our vegetable garden in order to have some fresh vegetables in winter.  We did get some cold loving vegetables like Chinese Broccoli, Swiss chard, kale, carrots and mustard greens.   Several times the vegetables inside wilted from the cold when we couldn’t get access.  In the middle of winter when snow piled two feet up the frame, we couldn’t get the door open without a lot of digging.  But it still gave us a good head start for spring vegetables and we get to have fresh vegetables early in the season despite the seesaw weather.

The seeds I sow in November like spinach, Bok choi and mustard greens, sprouted early and became our first salad crops.

Inside our cold frame, the taller spinach are the one I sow in November last year

Then I sow more cool weather vegetables like Mizuna, Shungiku (Tang Oh), Chinese broccoli, Corn salad, arugula and more of spinach and mustard greens in March when I got access to the inside. These will become our second crop.

I sow this patch of Mizuna in March. It ‘s great for salad and soup
Mustard greens from seed in winter grow among arugula
I usually thin the Bok choi so they will have room to grow bigger. I use the ones I pull out in salad
Shungiku or Tang Oh or Edible Chrysanthemum love the cooler temperatures. I prefer them in soups

Since the cold frame has no ventilation, early spring is when we have to be careful.  We need to leave the door open on hot days otherwise the vegetables in there will be cooked.  I devote this patch under the cold frame for growing leafy vegetables because it provides shade during the summer months.  Once the plastic is cover removed, I grow Bitter melon and beans and let them climb up the frame as they provide shade for the vegetables below.

With a couple days of heavy rain other vegetables in the garden double their size.  Asparagus shot up a few inches a day with rain.  We were supposed to cut them when they reached six inches high but…

We didn’t have time to cut the asparagus when they should have, but they still were delicious
Siberian garlic

After it was fed and with plenty of rain, our garlic, both Siberian and Rocambol garlic, got much bigger very fast.  We had a good garlic crop last year and still have some left in the basement.  So far this year should be good too.

 

 

Maximizing Space

Growing Vertically

We devote only a small part of our backyard for vegetable gardening and I’m always looking for a way to add more plants and increase productivity in the existing space.  Though we have put a deer fence up around our backyard, we still have to put a low fence around the vegetable garden.  If we don’t, there would be nothing left.  Deer cannot get in our back yard but rabbits, woodchucks, squirrels and chipmunks are still able to sneak in and enjoy what we grow.  So we are limited to growing vegetables within this little fenced in area, therefore I try to make every inch work to its maximum productivity.

Looking back at the last season, I note what worked and integrate it into the coming season along with whatever adaptation increases efficiency.  The method described below can be used for any plants that grow vertically, not just vegetables.

Aside from incorporating different plants in any one plot, I also grow vertically.  While most gardeners grow beans on a cone shaped ‘teepee’ I believe, I put up a trellis for beans that’s over the path, high enough to walk under, and grow beans on each side.  Last season, I put one up by the vegetable garden entrance.  It worked well and when the beans were fully grown and had developed pods, it looked beautiful and provided easy access for picking the beans too.  The trellis can be moved to any part of the garden easily when needed or I can grow different vegetables on it.

The bean trellis early last July. You can see the netted frame structure behind it.
Toward the end of July, beans have grown to cover the trellis with plenty of pods. It’s easy to walk under when picking beans.
I’m not sure what type of beans these are but their ancestry is Italian. My neighbor brought the seeds back years ago and we have been growing them ever since. They are delicious as young pods as well as dried beans later.

Once the weather was warm enough to remove the plastic from the cold frame, I put up a net in its place, see the first photo, to filter and soften the sunlight.  It reduces the light by about 50%.  Leafy vegetables like lettuce, Mitzuna, and Pac Choi prefer a little shade.   In the middle of summer, when the temperature is high and the sunlight is strong, these leafy vegetable will bolt easily and the lettuce will turn bitter.  With shade over them, they can take their time to grow, their leaves are crisp and sweet and the soil will dry more slowly.  I grow Bitter melon on the side of the frame structure and let them entwine themselves up the frame.  I gradually roll back the filtering net as the melon plant grows allowing it to take over shading the vegetables below.

Bittermelon growing up the frame (see first photo) and completely covering the top of the structure, providing shade for the leafy vegetables below.
The melon fruit hangs down making them easy to pick
Early in the season when the structure still cover with a filtering net. Vegetable that do well in semi-shade here are-Left front to back- Wasabi Arugula, Chinese broccoli, two types of lettuce. Right front to back- Mizuna, three types of Mustard greens
Later on when the melon plants cover the structure, I put in more lettuce like ‘Spotted Trout’ and ‘Truchas’

One down side of having the vegetables grow up the frame is that I have to cut them all down when the temperature threatens to drop close to freezing.  I need to put the plastic back on and turn it back into a cold frame again.  Most gardeners leave the plastic on but open the ends of the structure to let the air flow through in summer.  I could have done the same but I would lose growing space on the top of the structure.  I would also have to put a smaller frame over one of the 3’X18′ plots and cover it with a sunlight filtering net to grow these vegetable in the heat of summer.  I prefer to kill two birds with one stone: shade the vegetables and have extra growing space.

Benefits Of A Cold Frame

Early Bounty

We set up a cold frame for the first time last autumn but it didn’t do much for us this winter because we installed it so late in the season.   However, it provided us with a place to start our vegetables early.  The seeds were sown in March when some days were still hovering around 20ºF here.  We were able to pick our first salad of the season in April when  temperatures outside were in the mid 30ºF to low 50ºF.

The weather is still unpredictable.  Temperatures have been swinging between 70ºF daytime and a low around 40ºF at night.  It’s still too cold for many vegetables to germinate outside, but I have sown scallion, Mustard ‘Dragon Tongue’ and Oakleaf lettuce in the plot outside the cold frame and it seems to be taking them a little bit longer to sprout.  But I can wait as I still have a lot of vegetables to pick from in the cold frame.

Aside from being able to grow leafy vegetables in the cold frame on an early schedule, I’m also able to use it for strengthening the seedlings.  Plenty of sunlight can get through the plastic but not direct sun and it stays warm enough in there to avoid stunting the growth of the seedlings.  I have to be careful to open it up during the day when the temperature reaches above 50ºF.   It becomes a sauna in there if I don’t open it.   Too hot or too cold is never good for growing anything.

This one worked so well that I’m tempted to get a larger one that will cover the entire vegetable plot.  Maybe I could go through winter without ever buying salad from a store.

Spring Vegetable Garden

Sprouting Time

After a long wait for fresh backyard salad, I can hardly stop myself from sowing seeds in the vegetable garden.  As soon as the soil softens, judged by seeing weeds coming up, I put Arugula, Radish (Cherry Belle and French Breakfast), Pak choi, Mizuna, Kale, Swiss chard, Scallion, Lettuce, and Broccoli Raab in.   The arugula is always the first to come up.

I also put Snap Peas in the soil directly.  I find that they grow stronger that way than starting them in a container and replanting them.  I just soak the seeds in water for a few hours, placing them between damp paper towels.  The roots will sprout out in two nights.  I drop the ones with roots in the soil and cover them.  I don’t have to worry about hardening them.  If they feel it’s the right time to poke shoots above ground, they will. They are already a couple of inches tall now.  I will have stir-fry sized pea shoots in a couple of weeks.

Some self-sown Broccoli Raab, Borage and Calendula also came up.  Last year’s Red Russian kale, Scallion and Radicchio looks pretty fresh and healthy.  I can pick them while waiting to thin the seedlings (great baby greens for salad).  I also picked my first Asparagus of the season last weekend and will have some more this weekend.  Garlic is looking lovely at this time too.  I have already fed them once.

Yes, the tomatoes have sown themselves again.  They are just an inch above the soil surface right now, not big enough to be transplanted yet.  I will take most of the Borage and Calendula out from the vegetable garden and transplant them along with the flowers.

Anywhere I turn there are signs of new shoots and leaves unfurling, another cycle of life has begun.

First fresh, sweet, asparagus of the season.

Borage sprouts up right next to the garlic.  I keep a few of them in the vegetable garden, but this one will have to move.
