Daphne Yellow patches on leaves

vonny232vonny232 Posts: 6
Hi, I have a daphne "perfume princess" shrub I planted last autumn. The leaves are going a bit yellowish in patches. It's growing in a raised bed with a compost/soil mix. 

Any ideas why the yellowing please?

    ...are you gardening on alkaline soil?  I had a huge Daphne here, it didn't stop it growing or flowering but the foliage turned chlorotic like that... my soil ph is very high, very alkaline..

    .. you might like to feed it with a chelated iron solution.. sequestrene.. that would help.. or a feed specific for acid loving plants...

    It looks chlorotic to me which is basically yellowing of the leaves due to a lack of nutrients, usually nitrogen, iron and/or magnesium.

    You can fix it by giving it a generous dollop of pelleted chicken manure for nitrogen; a regular liquid feed of sequestered or chelated iron for ericaceous plants from good garden centres and DIY stores and, for the magnesium, a liquid feed of Epsom salts.  You dissolve 15ml of slats in 5 litres of water and pour over the foliage and around the roots using a watering can with a spray nozzle.

    Thanks folks.

    I am in Ireland and the soil is quite alkali, I have a huge sack of Iron Sulfate (which I normally use to blitz the moss on the lawn).
    Not sure if I should use this (as I dont know the measurement size and dont want to over-fertilize it) or buy a purposeful Iron feed?

    I doubt very much its a general nutrient deficiency though...

    You could try Epsom salts - they contain magnesium which is what your plant needs.
    1-2 tablespoons per gallon of water and drench the soil around the plant.
    A one-off treatment should be enough.

    The only other possible reason is that the soil is very compacted around the plant which may cause a Nitrogen deficiency.
    But the leaves look like they have interveinal chlorosis which indicates a lack of magnesium
