The cucamelon plant is related to cucumbers, and they’re easy to grow in containers or garden beds. They develop an underground tuber throughout the season.
In hot summer areas, such as Arizona’s low desert, the best time to start them indoors is between January to March and mid-July to August. Plant the transplants outdoors between mid-February and April and mid-August to September.
The seeds should be planted between ¼ and ½-inch deep, and the seeds will take a week or two to germinate. It can be hard to get them started outdoors since the seeds are slow to germinate.
It’s best to start the seeds about a month before the last anticipated frost date, which is also when you would begin to grow regular cucumbers from seed, well after peppers, tomatoes, and many other crops.
