fertilizer question for vegetables

 

I am a pharmacist and have a bottle of potassium nitrate.  I figure I
can just work it into the soil when I prepare my garden as
fertilizer??  Or should I sprinkle it on the ground after the plants
are growing.

I also have a bag of lawn starter fertilizer that has not been used in
almost 10 years.  I was going to throw it away, but wanted to know if
that would work for a vegetable garden.  Again, should I work it into
the soil before planting?


Thanks

 


I tend to sprinkle around vegetables as if fertilizer reaches plants
too fast it may burn it.  Because of this I do not fertilize
transplants until a week after they have been in the ground.  Lawn
fertilizer is OK to use but you might want to suppliment with K or P
if they are too low.  Also use limestone around tomatoes to prevent
blossom end rot.
