Greens in the garden

We went away for a long weekend and came back to a garden bursting with greens.  The swiss chard above is interplanted with leeks.  I chopped it down, and pulled some plants out to give the leeks more room to grow.

The other green I pulled out was the vitamin green.  I had such high hopes that it would push through the bug problems but I was wrong.  Or maybe I'm just too lazy to deal with all the bugs.  Hole-y leaves aren't that appetizing anyways.  So I pulled it all out and planted basil in it's place.  I'll try planting it again later this year and keep row covers on to keep the bugs out!

We have a lot of other vegetables growing in our garden, like the scallions above.  Aren't they cool looking when they emerge?  Our garden neighbor is growing a lot of mesculn mix (above right).  I counted at least five varieties of greens.  Can you name any of them?

plant profile: cressida

I found cressida in the Johnny's catalogue and wanted to try it out because it looked so pretty.  It is also "typically grown indoors in flats or soilless culture" which is exactly my situation.  I planted it three weeks ago in a warm 60 degree greenhouse so I could see what it was like asap.

Isn't it pretty!  "Peppergrass" is another name for it.  I tasted it as soon as the first leaves emerged and can say this green lives up to it's name.  The initial flavor isn't pepper-y, to me it takes a bit like green apple.  Then, after a moment there is a spicy flavor akin to arugula (but not exactly the same).   The little greens have brighten up my salads, but a full mouthfull of cressida is a bit too much so I use it sparingly.

plant profile: Mizuna

Brassica rapa juncea

(kyona, shui cai)

Appearance - Mizuna is an upright green with deeply cut serrated leaves on thin white stalks.  It is part of the hot and spicy group of mustards in the Brassica rapa family but has a mild flavor.  It can tolerate both heat, humidity and cold weather making it a good year round crop.  

Uses - Originally, mizuna is from China but is thought of as a Japanese green that is primarily used for cooking.  Here in the west is mainly used as a salad green but as it becomes more well known its uses are growing to include stir fries and stuffing for raviolis.

Varieties

Culture - Mizuna is easy to grow and should be treated like other Brassicas.  Sow seeds 1/4 inch deep in moderate temperatures between 60-85.  Once the seeds have sprouted temperatures a bit lower, between 55-75 degrees, is sufficient for growth.  

For baby greens seeds should be sown in 2-4 inch bands with 60 seeds per foot.  For larger leaves sow only 15 seeds per foot in 2 inch wide bands in rows 18 inches apart.

Harvest - Baby greens should be ready for harvest in about 21 days, depending on temperature and light levels.  Full sized leaves should be harvestable in 40 days.  Mizuna is a cut-and-come-again crop and will produce multiple harvests.

Pests - Like all Brassicas flee beetles are the major pest of mizuna.  Using floating row covers is an easy method of controlling these pests.  For more information check out the UNH Cooperative extension's page on flee beetles.

mesclun

Endive, lettuce, arugula and chervil from Johnny's Seed Co.

What is mesclun?  The traditional French mix included only endive, lettuce, arugula and chervil, but now it can include any number of baby greens harvested and mixed together.

plant profile: lettuce

Lactuca sativa

Asteraceae family 

Appearance

Uses

Varieties - There are hundreds of lettuce varieties but we'll only be using leaf lettuces - those that don't form heads. Leaf lettuce seeds can be purchased as a few pre-mixed varieties which are chosen to compliment each other.

Culture - Lettuce is a cool loving crop best grown between 60 and 65 degrees Fahrenheit, but can grow in temperatures as low as 40 degrees. For salad mix or baby-leaf size sow seeds in a 2-4 inch band with about 40 seeds per foot.  Cover lightly with soil and keep it moist.

Harvest

Pests

plant profile: spinach

Spinach is my favorite green.  


It is not fast growing like some of the brassicas.  Nor does it have sexy colored viens like swiss chard or red russian kale.  Harvesting spinach can be a true labor of love when each leaf has to be cut individually.  Despite all of this, spinach is great.  No, it's beyond great - it is one really cool plant.  Here's why:

~ Spinach is a diecious crop meaning there are male and female plants.  In the absence of any male pollen producing plants female flowers can ‘revert’ to become pollen-producing flowers, enabling continuation of the sexual reproduction cycle.  

~ Spinach is one of the hardiest leaf crops. It grows best in sandy, porous soil but can adapt to a wide range of soils.  Spinach germinates best in cool soil and can germinate at temperatures as low as 35 degrees Fahrenheit.  

~ Spinach can grow at very low temperatures.  Other leafy crops can tolerate the cold but will not grow.  Spinach grown in the cold has higher concentrations of nutrients like vitamin C as well as higher sugar levels.
