Hi thanks for your responses. I'm based in London UK, I shall go fill in my profile shortly.
Also I just wanted to add. My 3 wild Orange trees I have, I grew from pips from store bought oranges there about 5 years old now but they have always stayed small at around half a foot so I think there possibly lacking in nutrition as I feel they should be at least 4 foot by now I will get some citrus feed for them however I did mix in some plant food a few days ago so I'm just wondering if I added some citrus feed as well would that be over feeding them? Whats the most recommend citrus feed?
Many thanks.
