Why do plants die if you give them too much fertiliser?

Answer 1

Excellent question.

This is due to a process called osmosis. Osmosis is the net movement of water molecules in and out of a partially permeable membrane (a kind of barrier that only allows certain molecules to pass through), from a region of their higher concentration to a region of their lower concentration.

Its pretty self-explanatory here. Since the concentration of water is higher inside than outside of the plant, water moves out of the plant, resulting in the plant dehydrating and dying.

Answer 2

fertilisers are like salt to plant,

if u eat too much salt, u'll get dehydrated and die too.

so, water the plant before or after putting fertiliser and do not put too much.

Answer 3

Because the roots are very sensitive and a high dose of fertiliser will burn them.

Same reason you would die if you kept eating vitamin pills like they were candy.
