Why do plants grow to­wards the light…

Go Gardening - - Design -

Hor­mones called ‘Aux­ins’ in­side plants grow­ing tips, are trig­gered by light to in­flu­ence cell di­vi­sion. If the light is to one side, the cells on the dark side re­ceive more auxin and di­vide more rapidly forc­ing the plant to bend to­wards the light. If the light is from above, the plant will grow up­wards at a faster rate. Lanky ‘stretched’ growth is a sign that a plant wants more light.
