A GARDENING GENTLEMAN’S THOUGHTS ON THE CICADA…
The upcoming mania about the awakening of the “Cicadoidea”, (or
Cicada in the vulgar tongue), is a worthy concern for our gardening gentlemen. To cut to the chase, Cicada’s feed on the sap
of deciduous trees including their trunks, branches and roots but are
altogether uninterested in coniferous plants.
Unlike other pests they are not focused on foliage, rather they suck
xylem or sap from such trees as oak cypress, willow ash and maple, typically
causing no harm whatsoever. However, if you
are cultivating young saplings and want to forego the whole /cicada initiation
you might consider placing a light wire mesh frame over the saplings
encompassing them from their crown to the ground and then sheathing it with a
thin transparent mesh to allow for photosynthesis. But know that eventually, as the tree matures,
it will become defenseless against these insects as you will not be able to
sheath a fully mature tree. Cicadas visit
us every 13 to 17 years depending upon the species, so yours will be a long if not punctuated
relationship with this most curious of organisms. By the time the sapling has reached full
maturity these Cicadas will be of no harm.
In the wild every deciduous organism would be compelled to undergo this
crucible as one of nature’s fateful tests but in our gardens we have the
ability to cheat nature in effect to maintain the artificial order of our
beautiful domestic parterres.

Over the next few months the presence of our returned
visitors, the Cicadas, might attract predating insects and animals. Many scientists believe that the strange 17
year cycle of these insects is largely designed to manage predation by other
organisms, if so it is a truly ancient artifice. Female Cicada’s will lay their eggs deep in
the branches of deciduous trees using their proboscis, the same long, tube-like
appendage used to draw sap. When the
eggs hatch the newly minted nymphs will fall to the ground where they must
quickly burrow deep for the next 17 years.
It is at this time they are most vulnerable and most likely to become a
meal.

Other than superficial protection for young saplings there
is really no other concern that a gentleman gardener should have with the
Cicada. There are many sustainable ways
he might utilise them to his advantage such as composting the dry but protein rich
husks left by these morphing organisms. After
the first weeks of the Cicada invasion these husks will be left lying around
everywhere like dead automobiles in a junk yard. An enterprising gentleman might spend a few hours’
online collecting recipes and attempt adding roasted, fried, grilled, or
casseroled Cicada to his repertoire of cuisines. But for my part, I have determined to catch
all the Cicada I can so that I can feed them to my six, ever-hungry turtles
aptly named; Rampage, Muse, Dingo, Rumble, Base and Carto… respectively…
