Q.I Made Nettle Fertiliser And Applied It To My Veggies Without Diluting – Are They Doomed Now?!
I forgot to dilute the nettle fertiliser and added it direct to courgettes, runner beans, tomatoes and brassicas. Will this harm them and is there anything I can do to rectify?

You probably know by now if there has been an effect. Like any fertilizer, too much can lead to fertilizer burn. If you added lots of water to your plants once you realized you didn't dilute, that may have been enough to dilute or wash out some of the fertilizer.
The article below did caution against using it on tomatoes, because of the high iron content. It is best used on leafy veggies and heavy feeders. You are probably OK, though, since this is an organic treatment and you probably flooded the plants with water.
