I am growing a couple of containers of veg with my 4 year old granddaughter. Beans, carrots, strawberries and lettuce.
The lettuce are the ones that you pick a leaf off and it re-grows and are various coloured leaves.
Question is, I dilute phostrogen as a fertiliser, and the lettuce are very close together. Can I just water over the leaves and wash before eating ? Or should I avoid getting any fertiliser onto the leaves ?
