The UK's premier extended release, general purpose fertiliser.
Originally developed for use as a base fertiliser in John Innes composts, and still approved for use in JI formulations, Q4 has proved an extremely versatile fertiliser suitable for use on a wide variety of crops. Q4 provides all the nutrients and trace elements essential for vigorous growth, abundant flowering and ripening of fruit.
In addition to being an ideal top dressing for salad crops and ornamentals, Q4 is the perfect base fertiliser for use in both loam-based and soil-less composts.
