I fertilized my plants yesterday with some tomorite .today all leaves have changed colour .they are planted in ericanous soil .please help im new to gardening .I have been watering with rain water also .many thanks
How long have you had them? Young leaves are normally that colour at this time of the year, but if the plants are new, they may have been kept in warmer conditions before you got them.
Having said that, Blueberries in ericaceous compost must be fed with an ericaceous food, such as azalea and rhododendron feed, as the acid conditions block the uptake of normal fertilisers. To be safe, I would flush the tomorite out of the compost by watering the pots heavily with rainwater a couple of times (leave them for a few hours to drain, in between soakings) then leave them alone for a few weeks. There is no need to feed blueberries until the fruits start to set.
A trowel in the hand is worth a thousand lost under a bush.
I got them october or November. Thanks for your quick reply .I watered them a few hours ago .Will water them again .hopefully I haven't done them to much damage
