It's only about 6 ¹/² ft tall.  The pseudostem is a bit small in diameter, and will need staking

Fresh Sunrise (aka Strawberry) papaya seeds.
Grows fast & fruits quickly

I say full sun.  More heat, the better

Starting in October, I spray with neem oil (about 1 tbs w/ 1 tbs liquid soap in a 32 oz spray bottle of water) weekly.  I have 2 sample bottles of Dr. Zymes Eliminator, and have been using that with the same regimen.

Yes.  I'm unsure about restrictions to Belgium

Cleft grafts are good, too

I'm not a pro, but nearby Santa Barbara is prime cherimoya growing territory.

I tried sourcing some Inchelium Red garlic, to no avail.

I bought a few garlic from the local farmer's market, split off some cloves, leaving the skin on, and planted them.  Almost all sprouted. 

I also grow yellow potato onions.  A little larger than scallions, because the bulbs multiply, I have a endless supply of onions.  Less messy than Egyptian walking onions,too

Fruit Punch is a more highly regarded cultivar

How would you rate pitogo against namwah, praying hands, dwarf Brazilian etc.?

I would like try growing a mango tree in Long Beach, and after reading through this thread it looks like mango seedlings are the best way to go. Is there somewhere I can go around Los Angeles/OC to buy different varieties of the fruits (for seeds) or do I need to order seeds online? I know there are tons of mango varieties available at stands in Florida, but I've never seen any varieties other than Alfonso or the regular Mexican mangoes here. Is it easier to just plant a manila and then learn how to graft?

Buy Ataulfo/Manila, Kent & Keitt mangoes from the supermarket, then plant the seeds.  Watch videos on cleft grafting, and buy grafting tape ( Parafilm, Buddy tape) and a grafting knife or a razor blade.  Source mango scionwood from other members.  You can also purchase scion at tropicalacresfarms.com in the summer.

I've been curious what the "resin" taste is like?  I've not had the chance to sample as many different types, so trying to pin down that characteristic.  I've tried some imported Kensington Pride that had what I might consider a resinous aftertaste, although I might stretch it further to more of a gasoliney flavor.  Perhaps a closer resin hint I've tasted would be in some lesser ripened Valencia Pride.

Buy an Alphonso and/or Kesar mango from an Indian supermarket.  You'll see right away.  Little India in Artesia is not too far drive from you.
