I have been reading about cures for 'blossom end rot' and I find that the methods for
curing are not very clear and contrasting. Some say water deeply and less often
and others say little and often and to apply a mulch around the base of the plant.
I have 27 plants in a polytunnel and on one plant two tomatos on the same truss
have blackened undersides.
I have used 2 feeds of nettle liquid fertiliser but have stopped this as too much
nitrogen isn't good.
I now feed once a week with a tomato feed and water twice a week.
The tomatos are in plastic pots and I leave the 6 window vent flaps open
permenant. The temp during the day is between 25/30 degrees.
Even though I water twice a week the soil seems to dry out very quickly between
Any help appreciated as to remedy this.
