A few days of blue skies and warm sunshine is all it takes to turn one’s thoughts to spring.

Over the last week of clear weather, temperatures have been cool at night – like in the low twenties – but have been getting up to the low or even mid-sixties during the day. In the greenhouse, minimums are in the low forties, with maximums reaching the low seventies. Time to plant seeds!

Two weeks ago I planted seeds left over from last year: the first batch of lettuces, and herbs – parsley, chervil, cilantro. Those seeds have already sprouted. As soon as the plants are big enough, they’ll be set out in cold frames, where we’re still harvesting lettuces planted last fall.

This weekend, after a seed-buying expedition to Nichols in Albany, it was an orgy of planting. Six types of lettuces: Australian Yellow, Black-Seeded Simpson, Flashy Butter Oak, New Red Fire, Red Velvet, and our old favorite Merlot. Artichokes, to replace any that may not have survived the brutal cold of early December (at least some old plants show signs of new growth, too soon to know how many). Two new varieties of cabbages – Megaton and Stonehead – to expand on last year’s very successful experiment with sauerkraut. Cauliflower: Snow Crown and Cheddar. Lemon cucumbers. Tomatoes: Oregon Spring, Siletz (would have planted Legend, but I proved to have saved an empty seed packet). Peas, snap and sugar pod. Winter squash – Cornell’s Bush Delicata, our favorite (I know, it seems awfully early, but you catch the planting bug . . . ). And flowers! Sunflowers, pansies, violas, nasturtiums, all in several varieties and mixes. All to be set out at the appropriate time.

Even with all this planting, the greenhouse isn’t even near full. No more seed trays in the windowsills in the house!

We got a whole selection of commercial-grade seed trays in various plug sizes from Yarnell’s Red Barn nursery in Stayton – for a mere dollar each. The planting mix we made ourselves, from compost run through our Steinmax chipper-shredder.

Garlic, onions, and shallots have been in the ground since last fall. Oops, forgot the leeks! Put that on the list for the next visit to Nichols, along with Legend tomato seeds and doubtless a few others we’ve overlooked.

Over the weekend we raised the borders of the herb garden and added several inches of compost. Got the raspberries pruned, and dug up a couple of dozen plants to give away to friends.

Now comes the true test of the greenhouse, to see if we can sprout all these seeds with no heat other than from passive solar gain, and no protection from cold other than thermal mass and insulation.

With the greenhouse project done, it’s time to put it to use. We’re going to try growing tender herbs (chervil, parsley, cilantro, even basil) over winter, and experiment with tomatoes.

In the past, I’ve been using our own compost for planting seeds. Everything goes into the compost pile: food scraps, garden waste, grape stems and pomace. Turn it over once, and a year later it’s transformed itself into beautiful rich, black, and crumbly soil. Our compost bin is to the right in this photo.

That’s composted bedding straw from the sheep barn on the left, under cover to keep it from getting saturated over winter.  It will go into the garden and vineyard next spring.

I got some used seedling trays, cheap, from the Red Barn Nursery in Stayton. Perfect for starting seedlings for transplant into larger containers as they grow. But the compost as it comes out of the bin is a little too coarse than it ought to be for starting seeds. I tried putting it in a blender, but that didn’t work. The solution: a big blender, in the form of a Steinmax 1800 electric chipper/shredder.

The Steinmax 1800 sold in 1986 for $230. I found one on Craigslist for $75. It needed a bit of refurbishing – welding, hammering, patching, rewiring, lubricating, painting. The results?

Beautiful stuff, the texture and color of coffee grounds.

We used to have a big, gas-powered chipper/shredder, thinking that we’d shred plant material before it went into the compost bin. But that didn’t work well, it was too much work, and the machine was hard to start and noisy to run. We soon sold it. But after a year of composting, the course compost (fine for amending soil in the garden as is) slides readily into the maws of the shredder. Letting all the heavy lifting happen by itself in the compost bin is definitely the way to go. Do seeds like it? See for yourself.

We’re still getting fresh peas out of the garden, despite repeated frosts and rains. Here’s how.

A similar cold frame will enable us to harvest lettuces all winter – as long as the gophers don’t move in.
