Iris Feed / Fertiliser
We offer essential Bearded Iris Feed in 1.5kg bags. Tall Bearded Irises need feeding twice a year in Spring and Autumn.
Apply in March/April to give your irises the nutrition required to ensure good and sustained flowering. Our mix includes bonemeal, potash for root growth and superphosphate to stimulate flowering. One good handful is required per clump of plants, fork lightly into the soil and water. In dry periods water well after fork in in the fertilizer mix.
Apply after flowering in late June/early July to give the plants a boost and ensure they are in good condition before the winter/dormant period.
Bearded Iris Feed applied this way will keep your plants in top condition.
PLEASE NOTE THAT NITROGEN BASED FERTILISERS SHOULD NOT BE USED. THESE STIMULATE LEAF GROWTH AND INCREASE CONSIDERABLY THE LIKELIHOOD OF RHIZOME ROT.
