In yesterday’s post, I referred to my science unit on plant reproduction. In the terrific Earthbox Junior, our plants grew at a phenomenal rate. I used nutrient-rich Happy Frog potting soil from a boutique plant store to avoid introducing any unwanted bacteria or critters into the planter. The plants also came from that same pricy store. So far, so good, as long as my dearest teaching widower didn’t ask how much it all cost.
Alas, I forgot to add moss, which has a nice spore method of reproduction. At that point, I decided to try a novel approach and go frugal. Our yard has a growing mass of moss, since the deer have eaten everything else. I culled a nice sample and watched it die in the planter. But to our surprise, the “dead” ornamental moss around our bonsai ficus tree sprang to life! All was good and we kept a close watch for the spore cycle of the moss.
We examined the planter daily with a digital microscope and I nearly fell over when some giant legs and antennae shot past the screen. I’ve seen too many alien movies. The creature eluded us until it grew into a recognizable poisonous spider! What are the odds that a small sample of soil from my yard would yield a brown widow spider? The worst was yet to come.
Aphids appeared next, all over our nerve plant, so I doused them with soapy water and waited a day before examining their carcasses. As I carried the planter to our viewing location (AKA insect morgue), a sharp-eyed kiddo spotted tiny brown dots running around the planter. I had carried the Earthbox against my chest, so those dots also ran up and down my body. Further exciting microscopic investigation revealed dog tick nymphs. Hundreds of them, springing into life in my arms. Yes, I was bitten on my head, face, and ankle. No students were bitten, which was miraculous.
