I remember reading years ago about some plants where the plant grows and makes seeds, then the seeds grow and a plant that looks unrelated grows from the seeds. Then the new plant will grow and make seeds which grow into the plant that you started with. Can anyone please tell me what these plants are called, and where could I find information about them?

I notice that all instructions i have read about putting fertilizer on my lawn (e.g. Scotts Turf Builder Fertilizer and Weed Control) always says to use a spreader (or dropper) to put the fertilizer on the “surface” of the lawn.

From my understanding fertilizer contains valuable nutrients for the lawn (its food for the grass) and so i would best think it would work better if the fertilizer was closest to the lawn’s roots found far underneath the surfce. So how then is tossing fertiizer on the surface of the grass useful?

And wouldn’t weeds just use the fertilizer as food too?
If it burns them chemically because the fertilizer is so close to them then why do instructions mentions to use fertilizer in a mix with new seedlings — you dont get closer to that and would that then burn the new seedling because the fertilizer is so close?
