3/12/12: Starting Onions & Sweet Potatoes & a harvest

Last week I officially started the planting phase of my 2012 garden. I started onion and celeriac seed Wednesday 3/7. Thursday I put the sweet potatoes in water to root.

My potting bench: the top of the washer, protected by a drop cloth. At least water is close at hand.

Pots for starting onions.

The large open pots are called market packs. These have excessive drainage holes; I line them with paper to keep the potting mix inside.  In the 6″x5″ size I sow 45 onion seeds in three rows of 15.  There are also slightly smaller market packs (5.5″x5″) which I sow with 3 rows of 12 seeds. I don’t thin the plants, but during transplanting I will discard the smallest plants, usually 4-6 discards.

In the 3-cell pots I sow 2 rows of 5 seeds in each of the cells and I expect to transplant 25-28 plants.

The pots go into a covered plastic storage bin stored on top of the refrigerator. The seeds stay moist and warm to speed sprouting.

Pots with seeds are carefully placed in a plastic storage bin, the lid is put in place, and the bin is kept on top of the refrigerator until sprouts appear.

I check daily for sprouts. The first onion sprouts appeared this morning, 5 days after sowing. If you enlarge the picture you’ll find 2 or 3 sprouts in each row.

The first onion sprouts appear 5 days after sowing.

Today I’ll move the pots with sprouts under a fluorescent light in the (unheated) basement to grow. Only half have sprouts, but I expect the rest tomorrow.

My goal is to transplant around 270 onions in mid-April.

Thursday 3/8 I started rooting the sweet potatoes. The four varieties  (clockwise from the biggest) are Georgia Jets, Purple, Laceleaf, and Frazier White. All had developed tiny slips when I cured them last fall, and as soon as they got water the slips started growing. This morning I found tiny roots, 1/8″  – 1/4″ long. In a few days, I will be potting up these sweet potato mothers. (Note: I don’t use toothpicks to hang the SPs. The narrow containers hold them upright, and it’s OK if they rest on their ends.)

Spring Salad

The ingredients are mache, which sprouted last fall and overwintered; parsley, sprouting from last years plants; sorrel leaves;  and 2″ spears of new chives.  The mache was unexpectedly sweet, its flavor must be better in cold weather.

March 11 harvest: mache, chives, sorrel, and parsley.

  1. We will start harvesting our mache this week too!! Your salads look great! 240 onions! I have yet to get adventurous enough to start my own onions. I usually plant around 100 from starts that I buy around April 1st.

    • My onion timing is based on when my community garden plot will be available, usually early April. With that many onions I don’t want them too big at transplanting time.

  2. I should start my celeriac. 270 onions, that’s a looooot of onion to transplant. Only one of the 2 frazier whites I got from you rooted. The other is doing nothing, hope it start moving soon.

    • The Purple SPs are rooting fastest – they have 1/2″ roots already. The Frazier White SPs are slowest, they have no roots showing yet – but even so, your second one should be rooted by now. One of my 3 has at least 10 slips starting so there will be enough to go around.

      The onions are a years supply. They are almost half Copra, which stores very well.

  3. I’m in full swing of seed starting myself. Have also been harvesting some mache; not very big, but it didn’t sprout until after Christmas. But I always know when I get a mouthful in the salad, it’s got such a different sweeter flavor than lettuce!
