May 10 - Spring and Cicadas
Well it has been a
hectic month since I last wrote. We battled the onion grass that takes
over the garden each spring (though it wasn’t as bad as last year, so I must be
making some headway), composted and re-dug all the beds, and planted quite a
few spring crops. So far in the ground we have peas, fava beans, fennel, beets,
onions and shallots, celeriac, pac choi, radishes, salad turnips, lettuce and
spinach.

The hoop house is planted with cucumbers and melons, and the
first generation of cucumbers is already producing. With all the cool wet
weather we have been having, all the spring crops are pretty happy. A big
difference from last year when it was already pretty steadily in the 90’s by
now.

The summer crops are all waiting patiently to get into the
ground, except for the first generation of peppers and tomatoes, which we had
to re pot. My plan was to get them out this week but then came the
monsoon. In the end it was a good thing, as they are now predicting a possible
frost for Monday night. Now the plan has shifted to begin planting on Tuesday.
So next week will be big for planting, with not only peppers, eggplant, and
tomatoes going out, but zucchini, cardoons and okra as well. All of the
herbs should make it in next week too. We have added a few new herbs to
the list -- I found nutmeg flavored thyme, and a ginger flavored mint, that I
can’t wait to try. It will be a busy week, but well worth it when everything is
in the ground and happy.
Hopefully the frost doesn’t happen, but just in case I will
cover some of the more tender vegetables. The strawberries for example are all
in flower, and we are pretty loaded with small green fruits, which I would hate
to lose.
I wanted to take a moment and
talk about the 17 year cicadas that are emerging this year. A lot of
folks have been asking whether or not they will affect the garden. The
answer is no, though they may be so loud we can’t talk to one another. The only
things they may affect are young trees and shrubs as small diameter branches
are where the female likes to lay her eggs. If you are worried about some new
plantings you can net your trees and shrubs to prevent the female from laying
her eggs.
I saw my first nymph emerging the other day. They come out of the ground when the soil temperature is in the 60’s, climb the nearest tree and then shed their exoskeletons. The males start their loud signature song to attract the females. The females make no song though they will gesture with their bodies and wings, and make small sounds with their wings during courtship. After this they mate, the female lays her eggs in a groove she has cut in a small branch. The adults will all start to die off in mid-June. The egg later hatches, feeds on the fluid the tree is excreting because of the groove. That larval stage then falls and burrows down into the ground feeding on roots. After a determined period of time (between 2 and 17 years depending on the species) the nymphs emerge and start the cycle again. What exactly is going on with them during this time underground is still a mystery to scientists. Somehow they count the seasons, maybe through the roots of the tree, changes in nutrient levels, temperature etc. so that they all emerge together. It is thought they orchestrate these mass emergences to combat predators. The thought being if there are so many of them, even if the birds gorge themselves, many will still get through.

Birds are not the only ones to
delight on this mass appearance; many people are already posting their favorite
recipes. You can eat them at the nymph stage, and many believe that they
are a crunchy, tasty low fat protein. They will not
be making an appearance on our menu.
This year Brood II of the
Magicicada periodical cicada is set to emerge. This is a large brood, but
apparently nowhere near the largest. The reason this particular brood
gets so much hype is its size, but also the fact that it is one of the few
large broods that affects the New York metropolitan area. There are over 170
species of cicada in North America, and 2000 worldwide. Some have been reported
to reach 120 decibels with their song. So, though they will not affect the
vegetable garden for the most part, we need to prepare ourselves for the
cacophony of sound for the next few months.
