After hearing a few gardening friends from different circles talk about cucamelons , I decided to give them a try this year for the first time.
Cucamelons–also called Mexican Sour Gherkins and Mouse Melons–resemble tiny watermelons. “Vines start growing slowly,” notes Johnny’s Selected Seeds, and, “Not particularly high-yielding.”
After planting the seeds in early June, I waited for a few weeks and assumed they’d washed away before I saw any sign of them. The emerging seedlings remained tiny for another few weeks. Some just disappeared, likely eaten as a snack by a couple of flea beetles. The vines that survived grew so slowly that all nearby plants outpaced them, shading them and further hindering their growth.
Around early August or so, I finally started seeing tiny yellow flowers.
And by the time the fruit appeared, something else had already happened in my garden.
A cucumber explosion.
Evidently it was a banner year for cucumbers here in our area, based on the number of people at the garden talking about their great cucumber harvest. Which is great, of course. Only by the time the cucamelons finally made their entrance, I was already on the third act of cucumbers: canning and preserving.
But here they are, like fairy watermelons, alongside a cherry tomato and a scarlet runner bean for comparison.
Per Johnny’s instructions, I picked them when they were small, a little less than one inch. (Longer ones get seedy). Once the plants built up steam, they stretched out, clambering up the trellis and across the tops of my tall flowers. Cucamelons were tucked in all corners, though not in high numbers and not obvious among the foliage. I had to forage for them.
Their flavor? Like a slightly sour cucumber, lemony. Nicely crunchy. Their skin is a little thick. Sliced in half lengthwise, they’d probably make a nice addition to a fresh salad that I’ll be craving mid-winter. Or if I’d had enough at once, they might have made a nice jar of pickles.
A few takeaways…
- Given the slow start of summer in zone 6, I wouldn’t plant them any earlier here than I did, in the beginning of June. Even then, nights can still be quite chilly.
- I recommend protecting them under a row cover or cloche for a little extra warmth and insect defense.
- Just in time (hello, Frost), I’ve learned that cucamelons produce tubers that can be overwintered, which hopefully will mean a more vigorous start next season.
- Think carefully about space planning. The rest of your garden will travel into the future while your cucamelons stall in their own space-time dimension. They won’t grow well in the shade of other quickly-maturing plants.
- The cucamelon is no way to pad your harvest. It’s not like a hybrid cherry tomato, cheerfully producing early, across the full season, and in spite of disease pressure while you’re waiting for your heirlooms to come in. You may very well be weary of anything cucurbit-y by the time these guys produce.
- Is the novelty worth it? Maybe, and I’m willing to give it another try now that I understand more about its growing habit. I could see this plant working well in a garden where there’s not enough space for a full-sized cucumber beast. The cucamelon’s leaves and fruit are small and lightweight, unlikely to overwhelm surrounding plants if you don’t mind a little disarray and let a couple of vines ramble and find their way in the sun. Keep some sunshine carved out for it among your other plants, and it may perform better than mine did.
