Last year I started at about the same time, in february. It's a bit early for cucumbers and kiwanos right now but last year I noticed how this variety of kiwano (not sure which variety it is) took a while to set fruit. It really needs a very long season so it can only be grown in a frame like a glass greenhouse or inside of a poly tunnel. On my balcony last year they developed fine, but at the end of the year I had to cut off unripe fruits because I had no greenhouse. There was a large chance of autumn rotting away the beautiful fruits. It took untill december last year to ripen the fruits on the kitchen table.
I'm starting them inside a propagator with a transparent lid on, positioned at the windowsill on the south side of the building (as always), together with some outdoor cucumbers and other cucumber varieties. I hope they will sprout soon, the kiwano seeds are more than one year old so there is a tiny chance of nothing coming up. Let's pray for the best of it! Gonna have to hurry up building the greenhouse now
I've sown 10 seeds in two rows and covered the seeds with ⅓ to ½ inch layer of soil, it should be fine. It's important to keep them very warm, at least during the day, preferably above the heat radiator or carefully placed on a heat mat!
By the way, I used some thin cardboard boxes for sowing this time. The store had passion fruits in them.
