I miss my lemon trees! They made my apartment smell sooooooo good, and then -of course- lemons for dayz :sneaky: Not that I put lemon on absofreakinglutely everything, or anything <cough>. :whistling: One 4-5yo tree right in front of every window (I didn’t have a lot of windows, converted factory loft, three 5m tall x1m wide cathedral windows in brick).
I’ve only ever grown passion fruit vines in the tropics and just trailed them along anywhere I’d put jasmine or bougainvillea (fences, terraces, trellises, etc.) // ie full sun & keeps them up off the ground & keeps them occupied climbing things you want them to climb on, instead of everything you have to whack them away from. Indoors (not in the tropics) I’d think a (large) sunny bathroom would be best, for the humidity. Outdoors somewhere vines love to climb, but still in reach without a ladder. A sturdy bean-pyramid would also do nice. They’d probably do well on a wine-grape thingmy, too. (Technical term, that). Or a clothes line. You get the drift ;) In the tropics they tend to go gangbusters and attempt to take over the world. I’ve had a few lighter weight trellises just give up ...and the huge heavy fruit laden vine falls... and starts snaking across the garden overnight (I think it was heading for the highway). Cooler climate might be a bit challenging the other way.
One thing to note... they hate nitrogen. It will keep hem in a vegetative cycle for durn near forever, instead of a fruiting cycle. So if you’ve got any soil that “should” be perfect for tomatoes, but the tom’s hate it? That’s almost always a nitrogen deficiency. Passion fruit will Loooooove it. Plant those 2 things far apart from each other. And avoid commercial fertilisers like MiracleGro which are nitrogen based :wtf:
