Azalea nutrient deficiency or other?
Good morning all. Whenever there is a problem in the garden I always find this s the best place to find an answer. Sometimes scouting the internet can lead you in many different places.
I have a number of evergreen azaleas in a row ( not quite sure of the variety. However over the winter period a number of the leaves have turned yellow like the picture above. Also in some the plants they are starting look very sparse as if they have dropped a number of leaves.
is this an iron deficiency as the internet suggests? Is it too late to feed them or too early? And what would be the best remedy for the year of growth ahead?
im hoping someone may have an answer to this

It can be iron and/or magnesium deficiency which happens when the soil or water is a little too alkaline for them to take up these nutrients. You can correct it by giving a drink of sequestered iron around the roots and a foliar feed (spray or watering can with fine nozzles) with Epsom salts diluted in rainwater - 15ml to 5 litres. After you've done that, mulch the whole bed with a couple of inches of compost sold for ericaceous plants. Repeat as necessary.

Even evergreens loose some leaves over winter but I agree the specimen in the middle picture is too sparse. Good advice above the only thing I can add is you could use a liquid seaweed tonic instead of the Epsom salts if you have some.
Great thanks for the advice. I do have som maxicrop liquid sea weed to use as a foliage feed. Will ave to get some sequestered iron. Any particular brand anyone recomen or is it quite easily available and when is a good time to to apply this?
