Square Pots....

Thanks Marley,i think i`ll have to read the book again.I think ive got the P and the K mixed up.One of these days it`ll sink in. :D

 

Know what you mean, Elaine - N:P:K - all makes perfect sense when I read it - but can I remember? Nope! Always have to look it up! I had it written on the back of my hand for a while - no use! Got a mental block on the subject!

 

:D

 

elainefiz - you have got it quite right - the generally quoted benefits are N for foliage, P for roots, and K for flowers and fruit. I can remember that nitrogen helps foliage, I just have to remember that the flowers come last (you can't have flowers till you have leaves and roots). http://www.plantadvice.co.uk/help/show_question.php?id=9

If you can't remember when you are in the garden centre just look at a bottle of tomato feed. - its highest in K, the last one, that helps the fruit and flowers.

Having said that, when Googling I found one site that said it a bit differant http://www.living-learning.com/faq/npk.htm . So I am now confused myself. :D

 

Thanks, Peter - that helps a lot..... maybe.... :rolleyes:

 

Wonders never cease!I actually remembered.Thankyou Peter.

 

Oh, and if that site confuses you then i don`t think i should read it. :D

 

I switch as well Marley, when the flowers appear. But rather than buy a another expensive feed with a differant composition, I use my original feed at a lower concentration and just add Sulphate of Potash. http://www.gardenhealth.com/product_range/straights/potash.php This link shows that it contains on the NPK scale - 0:0:48. ie it's pure K (potassium). As it's just a simple chemical, its very cheap - much cheaper than than any other feed. And because its so strong you need very little.

 

Here's a link to a source of info about N:P:K - and suitable organic sources of what you need....

I found it quite helpful - and as I've said, I have a mental block on the subject!
