The mango seed has rooted and shooted! It's still in the shallow jar of water, but I've moved it from the hot water cupboard to on the warming shelf of our Stanley wood range. The shelf generally keeps between 20°C and about 38°C so it's a solid tropical temperature. I check and change the water every couple of days.
The seed has a bit of mold growth, but it hasn't bothered the root or shoot so I'm also not bothered by it. I'm thinking it might almost be time to get a bit of dirt involved.
I haven't started another seed yet, but the next time I'm at the supermarket I'll see if mangoes aren't an outrageous price. We're still a month or so out from Kesar season, but I'm also going to pop in to the local asian supermarket and see if they're planning to stock them this year - hopefully I can get my name on the list for a box when they come in.
