Do I have to dump all the soil from my flower pots for the Winter, or?

Excellent article on reusing old soil by adding to it. Too much detail to go into so check it out. http://6ftmama.com/stop-throwing-out-old-potting-soil/

I dump out into the flower beds. All the nutrients in the soil are used up, plants will not reach full potential. If a really big pot, take out the top half, fluff up the rest and add new on top. In small pots, use new soil for best results. Be sure to wash and sanitize pots before reusing. I wash with vinegar and set in sun.

I do the same thing Naomi does. I have a couple of spots in unused corners where I dump the potting soil, and after several years being covered with falling leaves, it actually has made those spots more fertile.

If you compost, add the potting soil to the pile.

Hi Diana. I leave my soil in the pots, and store the clay and ceramic ones in a shed. In spring I take a wagon and dump all of the soil into that. Then I mix in compost and cow manure and refill my pots.

Yes, it's a good idea to dump all the old soil. First, it's probably spent -- the nutrients are less as your plants grew during the summer. Second, insects can overwinter in the soil or lay their eggs in the soil and then you can have a problem with them in the spring.

I usually do that in the spring
