i've been looking at the state of the garden my landlord cultivates out the side of my little palheiro, and it's bothered me for some time how slow it seems to be growing and the yellowing leaves and necrotic tips

i was looking at it, and trying to remember what inter-veinal yellowing means... i was like "i bet it's magnesium" and i checked it out, and sure enough

it can also be caused by too much potassium, but i've never seen them fertilise the garden so the soil is deficient in magnesium... perhaps the sea spray contrbutes something to this

anyway, so i'm getting a bag of MgSO4 and gonna use my pump sprayer to give them all a foliar feed and hopefully this leads to everything turning green and growing faster

even the lawn has yellowing leaves, and almost every single plant has this problem

hopefully i've picked it right and applying the foliar feed is what they need, if i'm right, and it works, i will tell the landlord that they need more magnesium and avoid putting too much potassium in there

It sounds like you mean this in earnest, but it makes me chuckle that you turn off the computer and go to the garden for a break And then start doing chemistry.

phytochemistry!

i would love to grow plants, especially acacia obtusifolia trees, syrian rue, and lots of spinach and beetroot, olives... but more i want to keep goats... i will do all of these things in the future when i stack enough to get a little plot up the top of the island

but of course, i would love to do some organic chemistry, specifically plant chemical extraction :) with the acacias... just gotta find seeds... i know where to find them out there, but it's a long way away and it might be hard to get it back with me... but maybe... they are pretty small little black things, nobody's gonna know what they are especially if they are just loose in my luggage ;)

i'm betting they would grow very nicely here, another close relative, acacia melanoxylon, is something of a pest here, aka "blackwood" and it's somewhat similar both to obtusifolia and maidenii

probably can find seeds to order on the internet by now though, just would be a pain to deal with customs, easier if i could have someone just sprinkle a bunch of them in with some electronic item like smart cards or something and probably it will get through lol... damn... been a long time

also, sea spray, it could be partly to do with pH, sea water is slightly acidic, pure sodium chloride solution is pH 6.3

i'd guess that probably some lime will help too, i think i can get that from the local hardware store, i'll stick to foliar spraying the magnesium sulfate tho, will be fun to walk around with the sprayer every few days in the evening to give them a feed

i'm thinking about it mainly because it just looks sad with all the yellowing and slow growth, while i see almost everywhere else everything is booming righ now

i paid attention to all the plants as i was walking up the hill to go to the shop just now and i noticed that it is a somewhat common problem all around here, and even the leaves on the grapes next door seem to be suffering this

since it basically affects all plants i can see around, it definitely is some combination of pH too acidic and maybe insufficient magnesium in the soil

i strongly suspect the pH so i probably will also try and track down a sack of lime to sweeten the soil a bit, as they say. idk why they say that, lime is astringent, not quite bitter, magnesium, however, is slightly sweet

oh yeah, and a universal thing to do, add carbon to the soil, in this case, i bought 4kg of sugar and will cut a small hole in the bags and sprinkle it all over the garden area... carbon improves soil's nutrient buffering capacity by feeding bacteria that produce goop that has an ion exchange effect... i also thought about this too - to maybe put my cat's used litter, which will be full of ammonia, and scatter it sparingly over the ground to boost the nitrogen, since that also helps with green and growth
