I never lose a single salad leaf to pests,
I have rased beds for all fruit and veg, which are netted (buy netting from the farmers merchants much cheaper, buy everything from farmers merchants much cheaper than garden centres as most FM are non for profit) , more or less maintenance free, they are irrigated by drip freed from IBC food grade water tanks,
my salad beds are in lined galvanised water tanks, and cattle troughs, which are raised up on blocks, that sit on large rough granite gravel, I have plastic pipe looped over, which either has netting, or on some in the winter, they get turned into mini poly tunnels.
I have eight of these, provide all year round salad, herbs, beans, peas, the price of the years seeds is paid for in less than two weeks of harvest. I over plant, and pick as thinning out process, daily.
I have quite a small garden, but also have raised wooden beds, for fruits and larger veg, a combination of membrane heavy planting, means no weeding, or digging.
I put a strip of sticky back rough sandpaper type stuff around the bottom of tanks, so even is a slug or a snail made it past the gravel and up the blocks, they can't cross the tape, I have a pond, which brings in the newts, frogs and toads, I have a lot of slow worm habitat, they help keep all the slugs and snails away,
I enjoy effort free gardening, lots of companion planting, once you have set up properly it is just a matter of picking and eating,
if you use galvanised tanks, use a metal screw attached to a drill, rather than a metal drill bit, that way you only go through a couple of screws rather than a drill bit, it seems to work better,
great gardening system for renters as you can take it with you when you move, and the tanks stay warmer than ground planting so things grow faster.
I add feed/ compost into the soil before each new planting session, we garlic, salad , onions and stuff through the winter in the salad beds. nem
I use nematodes on incoming soil/compost, because it is a small eco system it works, salad beds are at thigh hight, so no bad backs, and children love tending them.
I save hundreds and hundreds of pounds by growing my own.
