Epsom salts (magnesium sulphate)  You can get it from the local lotty shop

or liquid seaweed

Not very high up on such things though as I tend to use comfrey tea for everything  :)

Oh, does liquid seaweed feed have high magnesium content??  That'll save me going and buying epson salts for my toms then.

I have no idea what the chemical make up of liquid seaweed is but it's good news for plants.  I think the idea is that if used regularly your plants will not suffer from deficiencies as it improves the plant's take up of nutrients.   Epsom salts is cheap though, especially in the lotty shop  :)

unsulphured molasses is also high in magnesium and will chelate other nutrients in the soil making them more available
helps feed the microlife in the soil too

A packet of epsom salts will last for two or three years , worth raiding the piggy bank. :)

I'm fortunate in living by the sea and make up loads of liquid feed from seaweed. Not only does it contain magnesium and zinc but lots of other trace elements and the alginates, the sticky stuff, help bind the soil so it can hold on to nutrients.

Nature will provide.

It must be great to be able to get it straight from the beach  :)  Mind you I only had to cart my seaweed from the shed shop to the plot, it was bagged and dry. Phew  :lol:

oh eck!  I wrote it down on my bag label (as I asked the same question) but I picked up another bag, so by the time I'd got to my plot I'd forgotten. doh

I Googled but all I seemed to find were instructions for using it for growing cannabis  :wacko:

I erred on the side of caution and added two small scoops to my 1.5 gall watering can

Thank you for your advice everyone, I will give epsom salts a go first.

I think its magnesium as leaves are yellowing a bit - just caught a couple of my squashes which are ready to go in, yellowing a bit too.  Checked the leaves out with online comparisons of mag def.

Compostqueen, by a small scoop do you mean around a tablespoonful??

those small scoops that come with granular fertiliser such as Miraclegro and the like

I asked the lotty man and he said one ounce to one gallon which he said was three teaspoons. As long as you don't add too much you'll be fine  :)
