The short answer to your question: YES
I am looking at 96 quart jars that will be filled by the end of the Summer with green beans, tomatoes, corn, soups and such. We've got the following planted so far:
~ 300 onion plants
~ 100 sweet pepper plants
~ 50 hot pepper plants
~ 500 bush pea plants
~ 40 cabbages
~ 50 broccoli plants
~ 1/8 acre of mustard greens + various other greens mixed in
~ 200 potato plants
~ 300 bean plants
~ beneficial bug mixes
~ poppies
~ wild flowers
~ herbs: oregano, thyme, rosemary, basil, tarragon, curry, angelica, lavender, parsley, cilantro, sage, mints, bay
Soon to plant:
~ 1000 corn plants
~ tomatillos
~ sunflowers
~ amaranth
~ millet
~ sesame
~ sweet potatoes
~ turnips
~ beets
~ carrots
~ sorghum
~ cantaloupe and other heirloom melons
~ cucumber
~ black eyed peas
We've already made 5 gallons of low-acidity vinegar, and will be making 10-20 gallons more of medium and high-acidity for canning. We still have peppers from last year, as well as sweet potatoes, garlic, winter squash, frozen berries, and a LOT of meat. I have been buying a lot of salt, rice and canning jars. This is all stuff that will be virtually impossible to get later. I also just picked up 1000 rounds for target practice with the ol AK-74.
We've all been warned. There's no excuse to not be preparing right now. You will NOT have an opportunity later.
