We have a wild little yard, considering that all the yard we got is a little concrete patio attached to our apartment.
It's much easier to maintain and enjoy a small yard, I think. When we had a (relatively) huge backyard, every plant that I touched dried and withered away. Except the mint, which grew into a mint jungle and started to take over the lawn.
Anyway, I'm wandering.
We have a few pots of plants that Summy and I maintain painstakingly. I had no idea how many pests want a piece of the plants. We dealt with aphids, ants, mildew, unwanted mushrooms, and caterpillars, all as humanely as possible (except the mushrooms, which make my skin crawl).

So we now have a few flowers blooming, and a couple of strawberry plants producing fruit at the rate of about one a week (which is great, but we supplement our one homegrown strawberry with four quarts of strawberries from the market every week). A few tomato plants starting to flower, some herbs, hot pepper plants in various stages, and a few snow pea vines that some mystery creature is eating up.
Most of these things were planted by Summy. She does not read the instructions on seed packets, she does not do research online, but somehow she gets it right if left to herself with some dirt and water.
That's it for the Flora. As for the Fauna:
We had a small wasp's nest on the fence that we took out. The wasps started working on a new one right away, and it was fascinating to see. We haven't yet had the heart to take down their new nest. They are peaceful and hardworking creatures.
We found a caterpillar having lunch on a strawberry leaf, and he got put into a bowl with dirt and leaves in it. Summy watched the caterpillar very carefully, but after looking down at all the leaves, the caterpillar decided this place wasn't for him and escaped while she wasn't looking. Ofcourse he got named before he left - Fuzzy.
We have a couple of spiders that spin the most beautiful webs. I take the webs down every now and then, just because they make the patio look unkempt. But they don't care, they always spin them again.
And ofcourse there are the ants, ladybugs, and plenty of other funny looking insects. Summy will get them into a bowl and observe before reluctantly letting them off to "go find their mommies and daddies and kids".
So much life in a few square feet, and these are only the things we can see.
