calcified organic seaweed

I am about to apply calcified seaweed to my flower and shrub borders. Are there any plants that would not enjoy this .

    Anything that like acid conditions such as ericas, blue poppies, azaleas, rhodos, hamamelis.

    Thanks i grew the Meconopsis Grandis from a packet of Thompson and Morgan seed last year and was lucky enough to enjoy a most wonderful display of blue poppies ,I wasn't sure if they had survived winter as I know once they flower they can die . Yesterday I noted they are alive and so I will definitely award them some seaweed crystals.

    No, the list I gave are acid lovers. Calcified seaweed is alkaline. Meconopsis will not like this. A peat dressing would be preferable.

    Peat!  image you'll have Monty doing cartwheels down his path if you dare mention Peat!

    HE! would use a barrow load or two of riddled leaf mould  to nourish them!

    Ps  How I wish I could grow the deep blue Himalayan poppies, it is too warm where I live and they turn out a wishy washy lilac, so I have given up trying to grow them!
