Turnip Testing 2011

Leave a comment

TurnipsWe didn’t have enough turnips in the Dirt to Dinner garden in 2010. Or in 2009 for that matter. When I was growing up in the 70’s in the suburbs around Cincinnati, no self-respecting kid would have eaten a turnip. Today, in California, I know kids who will happily eat raw, pickled, braised or stewed turnips without complaint. So, I guess we really are making progress. It just takes a long-range perspective to appreciate it.

Because the turnip is a popular vegetable around here, and we have an unexplainable deficiency in the radish growing department, we’d like to identify a turnip variety that does well in our conditions, grow a lot of it, save our own seed, and maybe even further improve or adapt the variety in the future.

This is probably a bad idea for several reasons:

#1. Turnips are biennials. They won’t even make seed until after they have been in the ground over the winter. Which means they are going to take up their space in the garden for a long time.
#2. Turnips are out-breeders so even if we grow only one turnip variety we could still have our seed accidentally crossed by a bee visiting from a neighborhood garden growing a different turnip variety we didn’t know about. But how many neighborhood gardens are going to have turnips laying around long enough to go to seed, you say?
#3. Well, it’s not just the turnips we have to worry about! Turnips are classified as Brassica rapa and could potentially cross with mustard, rutabagas, Chinese cabbage, Chinese greens or those radishes we can never seem to grow! On the up-side, Ecology Action’s booklet #13 “Growing to Seed” says we only need to keep seed from five plants to maintain enough genetic diversity in the line.

Not one to be deterred by facts, I went ahead and started Phase 1, which is growing several varieties in order to choose one to work with in the fall or next spring. This part just involves growing and eating. We have identified six types of turnip seed to trial, four of them were planted today and after the next storm front passes, we’ll add ‘Tokyo Market’ and ‘Tokyo Cross.’

2/23/2011 We seeded two 2.5′ x 2.5′ beds with turnips separated by a North-South running strip of ‘Petit Pois’ peas saved from 2010.

Bed A is ‘Scarlet Ohno’ from Bountiful Gardens vs. ‘Scarlet Ohno’ from High Mowing Seed. I’m hoping they aren’t both repackaged seed from the same farm! At the very least we should see some landrace variation. The Bountiful Gardens package says, “Greens are smooth and hairless, excellent for greens. Roots for fresh use and pickling, not keepers.” High Mowing adds, “Hot pink skins with white, mild and crunchy flesh. Excellent for baby roots or greens with a signature pink streak.” 50 days. The Bountiful Gardens pack is marked for planting in May-August, but I’m guessing that’s either not right or not for our area. Seems odd when everything else says, “As soon as soil can be worked,” or “4 weeks before last expected frost.”

Bed B is ‘Gold Ball’ side-by-side with ‘Orange Jelly’ with the same separating strip of ‘Petit Pois’ between the varieties. The Sustainable Seed package for ‘Gold Ball’ says, “…perfectly shaped 3-4” amber globes…never woody…perfect storage turnip for the root cellar.” ‘Orange Jelly’ is also recommended for its storing ability and says flavor is improved by frost. Might be nice to try these two again in the fall.

By about mid-April we should be munching, marinating, fermenting and baking our different turnips and picking a winner. Do you already have a favorite turnip that does well in your area or a favorite turnip recipe to share? Leave us a comment!

Worm Casting Experiment 1S

Leave a comment

On December 14th we seeded half a flat of ‘Guntmadingen’ Spinach in Ocean Forest potting soil. Ocean Forest isn’t perfect, but I’ve been happy with it and have used a lot of it this year.  Ocean Forest is a blend of worm castings, bat guano, Pacific Northwest sea-going fish and crab meal, composted forest humus, sandy loam, and sphagnum peat moss. Which brings us to the down-side, peat moss. I’m not sure how I feel about using it since it’s not renewable, most of it is imported long distances and it releases lots of carbon as it dries for harvesting. I need to research that to develop a more informed opinion.

My ideal would be not to need to use inputs like bagged potting soil but instead to make all our own compost and seed-starting mixes on site. It’s good to have a goal, but this one might be farther off than I would like since the garden keeps expanding.

Back at the spinach transplanting…

Roughly six weeks later, on January 22nd, we transplanted the best dozen spinach plants. They were all close in leaf size and root length. Six of the plants went into a container with more Ocean Forest potting soil on 6” centers. The other six went into an identical container in the same location with Ocean Forest potting soil on 6” centers. But, this group was also given additional worm castings by mixing fresh castings straight from the worm bins into the top 4” of soil before the spinach was transplanted.

Worm bin layerWorm castings have been shown to improve the activity of beneficial microbes in soil. I’ve seen some reports that 20% worm castings may be ‘ideal’ for flowers and vegetables, with additional worm castings not providing additional benefits. But since we don’t know what percentage of the Ocean Forest mix is already worm castings, we’re testing to see if adding our homegrown castings has a positive effect on plant growth.

Hoping for Asparagus

Mary Washington Asparagus Fail

Thin Pickin's

We finally did see two tiny tufted sprouts from the Mary Washington asparagus bed. I was actually about to dig the whole thing up to see what happened to them when I noticed the first one. Chalk it up to the weird wet cold spring. It’s not enough to keep me from over planting the bed in Tarahumara Chokame black beans, Catalina Spinach and Charentais melons. But still, two of the asparagus crowns are alive in there, and I left them enough space (I hope!) to develop through the summer and put down some roots for next year.

Asparagus from Seed

Italian Asparagus from Seed

My real hope is the Asparago Precoce d’Argentuil that I started from seed May 15th. Many of them have sprouted. They are tiny, thin, tall, fluffy things that move in the slightest breeze. I took this picture on the Sports/Action setting and it’s still not totally in focus. I probably breathed near them. In another week or two I will pot up the ones that I get into their own 4″ pots where they will spend the rest of this year. It takes about 305 days to get asparagus from this stage to the point where they have developed enough root crowns to go into the ground. That should see these guys planted out mid-March of 2011 ‘God willing and the creek don’t rise,’ as my Daddy would have said.

Asparagus Fronds

Purple Passion Fronds

There is one other hope in the asparagus department for next spring. In the fall of 2009 I put in four potted asparagus roots; two Mary Washington and two Purple Passion. They seem to have over-wintered well in spite of the onions, lettuce and carrots that surrounded them all year. Now they are sending up tall, broad fronds that should be nourishing the roots below and might give us our first taste of home grown asparagus next year. The potted roots were at least a year old when I bought them, so in the spring of 2011 they might be pushing three. If we’re lucky, and that creek don’t rise. ;-)

Wednesdays – Education You Can Eat

Leave a comment

Where does our food come from? How does it grow?  How does the way we grow food affect us, and the world around us? What is sustainable farming? What can we grow ourselves? How do we cook it? And, especially, how does it taste?

Education You Can Eat is a garden-centered hands-on program about food, nature, life cycles, cooking and nutrition. The program encourages participants to explore full food systems (“seed-to-table”) through both individual and group learning such as compost chemistry, bee gardening, nature journaling, botany experiments and cooking and preserving the harvest. Click here for a tour of the garden.

The program will meet on Wednesdays from 10:00-1:00 in the garden in the Santa Clara/Cupertino area starting April 28th, with a possible field trip to Full Circle Farm or Veggielution by arrangement with the group. (A June 9th Olivera Egg Ranch Tour will also be a wonderful addition to what we will be learning.)

The lead instructor for the program is Mackenzie Price, with assistance from, Joanna, a UCSC intern, and Gardener Juli. Parent participation is welcome and encouraged.

We have five spots available in the Wednesday program for kids working around the 2nd-4th grade level in Science. Please let us know by email if you would like a spot for your child. Send your message to dirt2dinner at gmail dot com.

We look forward to seeing you in the garden!

Bridging the Hungry Gap at Dirt to Dinner

Fresh peas

No Time to Cook These Peas

Historically speaking, this time of year was often referred to as the ‘hungry gap’ when food stored for the winter was running low–or running out–and spring crops had yet to produce. But this year the Dirt to Dinner garden is doing its best to bridge the hungry gap.

Yesterday we picked a big bowl full of ‘Petit Pois‘ shelling peas so sweet we ate every last one of them before we even started cooking. Today we tried the ‘Telephono‘ peas.  And there are four other varieties of peas ready to pick and six coming on soon.

There are lettuces for salad, along with celery, spinach and the last of the wintered-over kale, arugula, scallions and snow peas. There are still some carrots, parsnips, rutabagas, turnips and radishes in the ground. And the potato patch planted on Christmas is just starting to pass its peak of leaf growth. If we reached around under those slightly weathered branches, I’m sure we could find some new potatoes. And we may have to, as the last Dirt to Dinner ‘All Blue’ potato accompanied a pot roast into the slow cooker earlier this week.

Mini Purplette Onions

'Purplette' Onions Before the Dryer

There are plenty of herbs around to flavor whatever we do find to eat. We have chives, sage, thyme, oregano, rosemary and parsley all doing well, and some marjoram trying to fight its way back to full vigor. Some of the herbs are already finding their way into the dehydrator. Today we did three full trays of thyme leaves. Tomorrow I plan to add slices of green onion to the drying list as there are beautiful stems of ‘Purplette Bunching’ onions ready in the middle of the asparagus bed. There are also bulbing onions tucked here and there around the garden that we could pull and eat if we needed to.

But, thankfully, we don’t. We can wait and plot and plan for summer’s tomatoes, basil, beans, cucumbers, squash and melons. And sip fresh lemonade as we count the blossoms on the apricot, cherry, nectarine and apple trees. For this year at least, no one will be hungry in the Dirt to Dinner garden.
