I'm endeavouring to grow some apple seedlings and have noticed a slight red / brown tinge on the edge of one leaf on a few of the plants. I'm thinking that it may have something to do with a nutrient deficiency - perhaps phosphate.
On trawling through the internet I read that putting the used tea leaves from a tea bag into the soil can work wonders on your plant, and have then stumbled across the potential of watering your plants with (cold) tea dregs.
Can you do this (and what effect would it have)? Would it provide phosphate quicker than adding the tea leaves to the soil? Is this just a load of rubbish?!
Many thanks for your replies.
