I live near Vancouver, Canada, USDA zone 8a. Our summers are fairly mild, only becoming consistently hot from mid-July to end of August and maybe the beginning of September. I want to grow karela (the warty Indian bitter melon) or the Chinese bitter melon (smoother and larger). I have no idea whether the hotter part of our growing season is long enough.

I've saved some ripe seeds from some karela and I have 3 plants started - about 2-3 inches tall now. They're right against a south-facing window. I know a trick to get heat-loving vegetables to grow well in a garden and plan to use it. What I need to know, though, is how long from planting till the plant will set fruit. Like other Cucurbits, the first flowers will only be male.

Has anyone grown karela or bitter melon in this area and been successful? If you have, could you please share any info that could help me?

  • Why has this question been voted to close? It looks reasonable to me.

  • I completely forgot about my question. Probably should be closed because the few people who'd grow bitter melon in my area aren't the type to join SE. I know the answer now too as the hot and sunny part of our summers aren't long enough to produce much fruit before it turns wet and cooler. My attempt to grow the vines weren't successful.

    SE would benefit from this knowledge, so please post an answer because you can spare people of an unsuccessful attempt. Not necessarily a detailed answer if you don't have the time, but one that can be used to make a decision in the future.
