Nitrogen deficiency

Leaves appear small and chlorotic (yellowing) and general growth is reduced.  Red/purple spotting sometimes develop on the leaves as pigment levels drop.  Older, lower leaves are affected first but when the deficiency continues all parts of the plant can be similarly affected.  Premature leaf drop can occur.  Flower production can also be reduced.  Nitrogen deficiency can develop in any soils, particularly light soil low in organic matter, or if the soil has been heavily cropped.

Apply a Nitrogen-rich fertiliser to the soil. 

Product Solution: If Nitrogen deficiency is not too severe use a good all round compound fertiliser at the time of planting, spring and autumn such as Toprose or use Phostrogen All Purpose Plant Food for roses grown in pots and containers and for more regular feeding.
