Hello! This is my second year gardening in my home (last year was not much of a success for most - bad weather) but this year I wanted to more growing from seeds (kids get a kick out of it and it's educational). My question is I started all of my seeds basically with only a week apart. Some are growing faster than others but is there a 'Rule of thumb' when these can be safely transplanted outside (besides the obvious - post last frost). I've also heard that you should take the plants outside during the day to toughen them? Is that accurate? Thanks for any help.
FWIW I am planting Beefsteak Tomatos, Climbing Cucumbers (the seed packages do not do a good enough job identifying them as such), Climbing string beans (same thing), Peppers - bell, Eggplant, Squash, spinage!
