The summer gardening season is just about over. There is a chill in the morning air, we can now open our windows at night, and last night it was cool enough that we even had a fire pit in the backyard.
A few hearty crops remain, but most of them will have to be pulled in the coming week or two. Yesterday we planted the beginnings of our winter garden, which I’ll discuss in another post. Here, I wanted to talk about the good and the bad of our first summer garden and what we learned.
The bad first.
Three sisters didn’t work out as we had hoped (see June & July progress). The corn was the most successful – the beans and squash grew nicely (in the case of the squash – they grew huge!) but they produced next to nothing. Lesson learned: certain squash plants can grow absolutely huge, be careful selecting what bean and squash seeds to plant, and try hand pollinating the squash.
We planted the edamame late in the season, and they were growing nicely until we over-fertilized and they were pretty much dead the next day. The yard long beans were also damaged – we went from having nice, regular production to wilting, spotted leaves and few few beans. Lesson learned: don’t fertilize bean plants, or fertilize them very modestly.
The roma tomato plant never did well. The first one died thanks to a horn worm. The second one stayed alive but what little fruit it produced was eaten by birds. Lesson learned: spray for horn worms, and you need to protect a roma tomato plant from the birds.

In mid-season, a lot of our peppers were getting brown – some from blossom end rot, some just from the heat of the desert sun. Lesson learned: use shade cloths during the hottest part of summer, and manage the calcium level in your soil to avoid blossom end rot.
The cantaloupe plant was very disappointing. The few melons it produced never got very big and most of them seemed to be eaten by ants or rotted very quickly. The one cantaloupe we ate wasn’t very juicy (not quite ripe). Lesson learned: make sure things are ripe before you pick them – although I’m not sure what we did wrong on this one overall – perhaps it just doesn’t do very well in this climate, or perhaps we should try a different variety next time?
On to the good stuff.
We had a decent bean crop at the very end of the season. While the three sisters beans were a bust, the purple beans and yard long beans did alright.

Cucumbers were pretty amazing all summer long. We had more cucumbers than we could eat for almost the entire season (May-September). We just removed the plant yesterday, and were able to pick two last cucumbers – it wasn’t looking as hot, but it was still producing five months later!

Our Thai basil plant is also amazing, continuing to grow and be in great health so we’re going to keep her going. The other herbs didn’t take off as much (chives, peppermint, oregano), but are still healthy and we are still able to get use out of them.

The regular basil has also done very well. I just trimmed it back yesterday but we’re going to keep her going as well.

The peppers were another huge success. We had all kinds of mild and hot peppers, and nearly every single one produced good tasting fruit for the last couple of months. (See September peppers). We did try to plant some later in the season, as well, but they take a long time to grow so that’s not working out. These need to be planted early, especially if you’re planting from seed.

The watermelon plant did really well. It was planted later in the season (June), but it grows fast and has produced about 15-20 watermelons to date. Too much watermelon to eat, really. Funny our cantaloupes did so poorly but watermelon did so well. I think the watermelon had more sun, which could be a factor.

Our cherry tomato plant did well overall. There were probably in their prime in August, and there was a good month where I could easily pick a handful of tomatoes every day. We did have some problems with birds and insects, but it grew big enough that a lot of the fruit was well protected in the middle of the bush.

There was also a tomato plant that started growing unexpectedly in the community garden (a seed must have been in the compost), and as of yesterday it’s producing tomatoes so we might get lucky and have a small fall season of tomatoes!

Overall things we learned:
Shade covers are your friend in Tucson. They are necessary to stop your plant leaves from wilting and fruits from burning.
Covering our garden with shade cloth
Fertilize every 6 weeks or so, but don’t over-fertilize!
Water twice a day and use irrigation – once in the morning, once in the afternoon.
Try to keep your soil loose, especially after planting seed – most of this is when you are preparing your soil, but you can also use a claw and break up the dirt near the surface around your plants to help the roots grow.
Also, be patient and wait until something is ripe before you pick it. I picked an unripe cantaloupe and watermelon, as well as unripe eggplants (we had a mysterious eggplant grow near some pepper plants thanks to a seed in the compost). I managed to eat the melons anyway, but the eggplant I just had to compost.
Compost.
And finally, not everything is going to work well. Gardening is often experimental. There are some things we’ll definitely do differently next year. But it’s all a learning experience. We are very excited now to start the winter garden!
