Garden update:

Larger plants that are still actively growing: garlic, onions, peas (which are flowering), all kinds of peppers (there’s even one little banana pepper already), tomatoes, eggplant, blueberries. There are actually blueberries this year! I can’t wait. All of the fruit trees are now fully leafed out, but we had a late freeze (or two) and it looks like there won’t be much fruit. But there are three lovely peaches on Jan’s white peach tree. The tree is so small that it seems impossible that it would produce this year, but so far, so good:

We’re currently harvesting: strawberries (coming in slowly), chives (mmm, cheddar and chive bread), green onions, marjoram, cilantro, oregano.
Our Farmer’s Market starts this Saturday. It seems like it’s been ages. I’m very proud this year, because we made the cloth shopping bags for the Market:

This picture was taken before the bags were printed with the Market logo. I’ll post another when I see the final bags.
