Planting Cover Crops and Eating Zucchini

Cover crops are planted specifically to protect and improve the soil. Many organic farmers plant legumes after harvest in the fall to protect the soil over the winter, when there are no crops, then work the cover crop into the soil to provide nitrogen for next year's veggies or grain crops. Some farmers also cover crops in the summertime. Johnny's Seed Company sells some cover crop seed in small amounts for home gardeners.

A lab mate of mine is working on what combinations of summer cover crops give the best protective cover, nitrogen fixation, and weed suppression. After helping him sample his plots last fall, I decided to try buckwheat (quick cover) + crimson clover (a tropical legume that produces lots of biomass and hopefully lots of nitrogen!) this summer. These plants will die over the winter and I'll work them in in the spring.

I'm going to try to cover crop 1/3 of my garden each summer to build up organic matter (affectionately known as "OM" among ag nerds like me) and help break the life cycles of soil-borne pests, diseases, and weeds. On the other plots I'll plant red clover in the fall after harvest to over-winter (red clover is a lot hardier than the crimson clover).

After broadcasting the seed, I raked it in to improve seed-soil contact.

The tomatoes continue to grow well!

The peppers were not doing well (too cold and rainy) so I pulled them out and planted beets. Sorry, this picture is kind of fuzzy. It's hard to focus the camera on plants so small.

Some of the carrots never recovered from the munching of the bunny, but a fair number are bouncing back. I mulched in between rows to conserve moisture.

And the zucchini-nasturtium jungle continues to thicken.

More zucchini, almost ready to pick!

Over in the Little Garden, the broccoli did not like the shade -- some bolted, some got tall and leggy. But the spinach tolerated the shade well, so once I harvested my first planting of spinach I decided to plant more for a fall crop. Here I have two rows of soil open to seed.

Spinach seeds ready to be covered with soil. Spinach doesn't usually germinate well in such warm weather, but this is a bolt-resistant variety and the shade actually should help, in this situation.

And, back in the kitchen, I cannot keep up with the zucchini harvest! I'm eating it raw as a snack, in salads for lunch, and in tomato-zucchini stir fries for dinner! Good thing I like zucchini :-)

Raspberry Picking

The New World Agriculture and Ecology Group at Cornell went raspberry picking today at Grisamore Farms.

Allison and Hanh begin to fill their baskets.

The raspberries are wonderful this year!

Zucchini and Nasturtium Harvest

This morning I had my first harvest of zucchini and nasturtiums from the garden!

The zucchini-nasturtium jungle ... I never did thin the nasturtiums. I think they might be protecting the zucchinis from pests.

Yikes, zucchinis grow fast! This one barely existed two days ago. If I'm not careful to harvest often they might get so big they are only suitable for bonking people on the head! (I find that zucchini is most tender and yummy at a small size).

Meanwhile the Sungold tomatoes are growing like gangbusters.

The first Brandywine tomatoes have started to set fruit too.

First Harvest: Spinach and Radishes

Here's my first non-herb harvest of the season: spinach and radishes. The radishes were pretty small, but given the antics of our resident bunny, they didn't have a lot of leaf area to be photosynthesizing and sending sugars down to the tubers. The carrots seem to be greening up now that I fixed the fence, so maybe another planting of radishes will fare better....
