It might be good at the end of the year to review what happened in your garden and/or hopefully you took some notes last season. You can refer back to it instead of relying on your memory on what worked and didn’t work for future years. If you don’t like writing it down than use your computer. I still keep a notebook on when I start seeds, put them in ground, etc but I’m using the computer and my phone more and more these days for my garden notes. I like to go around throughout the season and especially at the end of the season before everything is torn out and make notes on my phone while things are still fresh, then I go back and enter them in on my computer where the pieces of the puzzle fall in place and are sometimes are very revealing as to what happened that year.
So this coming season if you haven’t been keeping a journal, write down important things like did you amend your soil, when you first planted seeds, when the first frost-free day actually occurred and did a late freeze sneak in, when you transplanted seedlings outside, did you protect them, how hot was the weather and for how long, how cold were the nights, how much rain did we get and did it do any damage (hail), which pests and disease were particularly bad, which plants did well, were they prolific, how long you could harvest certain crops, how long was the season and when the first frost got us.
Sounds like a lot of work? Not really. It’s just recording your OBSERVATIONS through the season and by doing it, you will become a better gardener. It helped me realize a few years back that one variety of tomato got Early Blight for 3 years in a row while the other tomato plants did not (it seemed susceptible to EB- I don’t grow that variety anymore) and that this past season, I could have started my seeds indoors much earlier than I did.
