Last week’s mild heat wave gave new life to the summer crops and forced me to withdraw from my “no more canning” stance. I simply couldn’t help but put up another round of pickled roasted peppers. Additionally, we’ve seen a new influx of cherry and slicing tomatoes, which are now once again covering much of our kitchen counters. But the real beneficiary of the warm weather was the string beans. I harvested almost 3 pounds in one day over the weekend and then another pound two days later! Harvesting beans even this far into the fall is something new for me. At the farm I managed until this year, we had a serious...
Panisse Lettuce
Yes, I couldn’t resist using this picture again! One of the benefits of participating in the City Harvest program is not just that I get free transplants in exchange for our donations, but more specifically that this pushes me to try new varieties of crops that I may not have grown otherwise. After years of farming, I have a personal list of my favorite varieties to grow. I know which types of lettuce do best in summer heat, the sweetest carrots, and the heaviest-producing tomatoes. This is great on the one hand, but in another sense can limit me from trying other, potentially even more amazing varieties. When I got the...
Bacterial wilt
Earlier this year, I talked a bit about cucumber beetles. You’ll find these little black-and-yellow striped or spotted bugs on plants in the cucurbit family like cucumbers and squash. While damage from the beetles to the leaves and fruit of these plants is in itself not that problematic, as the summer progresses these insects’ bites can transmit a season-ending disease for some cucurbits. If you’re a gardener, bacterial wilt is likely something you have seen before or may even be experiencing in your garden right now. This disease is transmitted from plant to plant when cucumber beetles bite and the bacteria can even overwinter in the beetles’ guts. Besides cucumber plants, bacterial wilt also...
A week away
Caleb and I took a short break this week, heading down to D.C. to visit my parents. Mike stayed home, so was able to take care of the garden, although with a week of successive heavy rain and thunderstorms, keeping things watered wasn’t much of an issue! At this point in the season, gardens become somewhat like pets, unable to be left alone for long without someone to take care of them. Most summer crops require harvesting multiple times a week to enable the plant to continue producing successfully, as opposed to concentrating its energy on going to seed. In terms of how often to harvest, here are the general guidelines I follow for...
Flea beetles
Flea beetles are one of those challenging pests that can quickly wreak havoc on crops and are also very difficult to eradicate once present. These tiny insects with their shiny black exoskeleton will jump away as soon as you get nearby, hence the name flea beetle. They go after many crops, but seem to particularly love arugula, the leaves of young eggplant, and the greens on turnips. The tiny holes they create in crops’ leaves are unsightly and can also diminish the plant’s ability to undergo photosynthesis, thereby decreasing growth and overall health. Once flea beetles have arrived, it can be quite challenging to get rid of them. When I was growing...
Cabbage worms
Cabbage worms are one of the most common garden pests in this region and, in a bad year, can easily decimate crops in a short time if not kept under control. Cabbage worms target crops in the brassica family, also known as cole crops. These include kale, cabbage, broccoli, collards, arugula, and mustard greens, among others. You’ve probably noticed the white butterfly adult form of these pests flying around from spring through fall. The eggs these butterflies lay on brassica plants will hatch into the small green, velvety-looking worms which can grow to a plump 2+ inches as they munch on the leaves of the plant. A sure sign that you...
Vertical gardening, simply
Using the vertical space in your garden is a great way to get the most yield out of a small area. There are tons of inventive, more complex vertical gardening systems, but you can still take advantage of vertical space while staying simple. It’s common to provide trellis support for crops like tomatoes and beans, but other crops like cucumbers, winter squash, and melons can be trellised vertically as well. All of these plants are expansive growers, creating a lot of green leaves and stems in proportion to the amount of fruit produced. Because of this, they can take up a significant amount of ground space, which can easily be freed back...
The crop pests cometh
There’s always that brief window in the year when I think, “Maybe this year is the year that I’ll have the perfect, pest-free garden.” And then they arrive! Despite a relatively light spring in terms of pest damage (we did have the broccoli annihilated by cut worms, but little else was affected), they’re here at last. The eggplant leaves are becoming speckled with the tiny, pin-prick holes that are the signature mark of flea beetles and, more severely, cucumber beetles have arrived to feast on the previously perfect squash and cucumber plants. If in your garden you’re noticing ragged holes on the leaves of these plants with the outside rim of...
Aphid honeydew
Are you noticing a lot of ants in your garden? This could be a sign that you have aphids, tiny insects that love eating a wide variety of plants. When aphids eat, the sugary plant sap is ejected from their bodies, created what is called aphid “honeydew.” Ants of course love to eat this sweet excretion and are therefore attracted to areas with high densities of aphids. But don’t worry too much. With the exception of grey aphids, which are a serious problem for brassica crops and appear more in the later summer and fall, I have rarely if ever had aphids be enough of a problem that the plants haven’t been able...
Harvesting lettuce greens
After a fun night awake with a baby with stomach flu, I got out as early as I could this morning to harvest the first of the spring mix! It’s important to harvest lettuce as early in the day as possible to keep the bitterness down. Surprisingly, lettuce contains latex, in the form of that milky liquid that leaks out of the stem when cut. At night, lettuce plants pull much of the latex down into their roots. As the sun rises and the heat of the day increases, the bitter latex is gradually sent back up into the leaf, explaining why lettuce harvested earlier in the day tends to be sweeter....
