this was my garden a few weeks back. i'm basically totally new at this despite having done this for a few years now and this is gonna be a sort of lessons learned kinda deal.
the story so far is that i decided i was too busy to fuck too much with replanting seedlings this year and figured that i would just go straight from seed, hoping that the unusually cold weather we were having in spring would kill most of them so i would have less work to do down the line. that was a completely unfounded and stupid assumption on my part and i had to replant/uproot a bunch of plants (see above) because i ended up just haphazardly scattering seeds everywhere and the distribution of plants was totally fucked.
a lot of them started flowering last week-ish so i decided to fertilize this week. this was initially impossible because i hadn't really done any maintenance on my little guys since i replanted them and so the place was basically a jungle. after two afternoons worth of effort the garden now looks like this (didn't really do much to the guys in the planter, there's a drainage layer but the big drainage pipe is above the drainage layer for reasons outside my control and i really need to get on that...):
all this to say that for anyone starting out, just bite the bullet and start your seeds off somewhere where you can keep track of them and replant them (IN AN ORGANIZED FASHION) later on. you'll save yourself a lot of trouble and won't end up spilling fermented soybeans all over yourself because you tripped over a potato while trying to maneuver yourself around your poor man's tomato cage.
this is my pet concern as well and it's always struck me as being bit darwinist. i cope by telling myself that instead of environmental evolutionary pressures, it'll be social and cultural pressures instead. so long as those pressures are grounded in material reality and are able effectively act on the population at large, we won't evolutionarily overfit and get stuck in some local minimum. all the more reason to prefer socialism over liberalism.
