I'm new to gardening and I just planted up an new border and added fish & bone meal to each plant. Now they are dying off and it seems from my internet research that I might have overdone the fertilizer! My question is should I dig up the remaining plants before they too start to die off? Should I water copiously in the hope of diluting the fertilizer? What's the best approach? I don't want to do nothing and watch all my hard earned pennies die off! Any suggestions would be greatly appreciated.
