Mine stay out all season. Just be sure the pots have good drainage.

Is the standard drainage on the plastic walmart pots (with the bottom saucer removed) enough or should I drill a few more holes?

Hi, drainage will depend on the growing medium in the pots and how dense the roots are. Several things to consider would be: 1. use a plastic mulch cover over the top of the pot. This would require you to lift it up to water the plant, so instead of that you might: 2. mix in a generous amount of gravel into the pot mix and mix in perlite. The rain would flow through while the perlite would store moisture in suffucuent quanity to provide for the plants needs. Only problem with the second option is that useful plant nutridents will be flushed out. If you use a liquid plant food each time you water, then it would not be a problem when excess water flows through the pot. My preference would be to use something like an expanded (baked) clay product (SHULTZ) in the pots because it readily passes excess moisture while holding moisture in it's microscopic pores. One other advantage is that plant roots do not stick to the expanded clay grains. You just shake the plant and it all comes off ready to use again. I used it quite a bit several years ago with great results. It rains a lot in Florida part of the year. chuck

I use pots with the drainage holes that come in them and Pro Mix or Fafard--similar peat based potting mixes. I use saucers under pots on the deck ( but not under the other pots) and if we get a lot of rain they need to be emptied. I fertilize with 1/2 strength 15-30-15 when I put them in their final pots and then only a couple of times during the season.

lol John.
I dont think moving your pots into shelter is even an option! By the time you moved them all the storm would be passed! :)

Right you are PR. But I'm glad for the rain because it saves me watering.Not so for hail storm last spring ( they eventually recovered)

Mightily impressive! I've got a 6'x12' garden that I will be planting most of my other Vegetables (have started 40 onions). I am planning to keep 50 Peppers in pots. I think I would definitely make a big and nice raised garden if I had that many plants! Just 30 pots last year was work. I cannot even imagine how much work it would be to do all those. Of course, the answer is one at a time, but man...
