ChemPak Plant Feed

Hi,

Have bought some of the Chempak Plant Feeds to try this year, being no2 and no3 .

Wondered if they can be pre mixed in a larger water container so its ready to use rather than adding the crystals to each w/can every time ?

Will it remain good for say up to a week or is it likey to loose some of its properties ?

Looked to ask on T&Ms Chempak site/page but they only take such question via their FB page which I don't use.

 

I haven't tried this, but I wouldn't like to keep them made up for longer than a week especially in warm weather. All sorts of things will love to grow in a warm nutritious soup. Although probably not directly harmful to your plants they will change the nutrient mix and its availability. They could also block roses, irrigation systems etc.

 

Good points - thanks.
