Is 0 10 20 (0 Nitrogen, 10 Phosphate, 20 Potassium) suitable instead of an official Autumn Lawn Fertilizer? I have this fertilizer at home and would save me having to buy other fertilizer.
They are good. but they only contain products that are available in neat forumations. If there is a problem with weeds in lawn. You best spray then fertiliser. The weed and feed are only good for mild cases. Also if you look at bag it gives the fetilizer formulation and also says chemical ingredient probally mcpa or similar.
I guess 0 10 20 would be similiar enough to 0 7 30 - BUT I don't think either is going to help your patch of ground this time of the year - as both contain NO Nitrogen - the first 0 represents Nitrogen - might be better to try 7 6 17 or even 10 10 20 - something with Nitrogen anyway. 0 10 20 and 0 7 30 are ideal in late autumn where you don't want the grass to grow
