With last Thursday’s hard frost, another year of backyard gardening has come to an end and it’s time once again to assess the results of a hobby that may not make much financial sense on an opportunity-cost basis–but which does allow a regular analog respite from all of my screen time.

(For reference: my 2016, 2015, 2014, 2013, 2012 and 2011 gardening grades.)

Herbs: A+

Planting basil seeds in a different, sunnier spot paid off with weeks of abundant leaves that I could toss into pesto sauces. The sage did even better and has kept on going into winter, although the relative lack of recipes for it means I’ve left most of the crop outside (any ideas to change that?). The parsley, meanwhile, rebounded from its subpar 2016 showing and once again led me to make multiple batches of tabbouleh in the spring. Mint, oregano, and rosemary were their usual prolific selves, and chives and dill did well in the fall. But cilantro only showed up in trace quantities.

Arugula: A

I got a terrific spring crop of this versatile green that lasted into July, then had another several weeks’ worth in the fall. If you’re thinking of starting a kitchen garden, this should be first plant you aspire to after parsley or basil.

Lettuce: A

Planting this in a sunnier spot paid off spectacularly well in the spring and summer, yielding an outstanding return on my investment in a couple of seed packets. If only I’d bought more: I couldn’t try for a fall crop because I forgot to purchase extras in the spring and then couldn’t find any after August.

Spinach: B

Last year’s plants held on through last winter–the day I got back from SXSW, one day after the season’s one notable snowfall, I brushed off some of the accumulation to pluck some leaves to use in a pasta sauce. It flourished throughout the spring but did not reward me with a fall crop.

Green beans: B-

These did great through the spring, but then some of our neighborhood’s many rabbits got into the raised bed and devoured the plants. Having enjoyed the Peter Rabbit books as a toddler, I can only laugh at the thought that I’ve become Mr. McGregor.

Tomatoes: C

Modest, incremental improvements at cultivating tomatoes did not yield a huge difference in this gardening paradox: I have no trouble getting tomato plants to sprout, but coaxing any to bear fruit is much less of a sure thing.

Cucumbers: F

Just to show that there’s no year-over-year logic to gardening, a comparable level of effort this year yielded 100 percent less than last year. Fortunately, cucumbers cost almost nothing at farmers’ markets.

Bell peppers: F

For yet another year, I got nowhere trying to grow these.
