Crop rotation, another of the many items I need to get familiar with. This will be our first 'real' or big garden this year. My husbands family always cracks an egg in every hole for tomatoes when planting. Then about 3 or 4 weeks they will grind a tums on each plant or more egg shells or water saved from boiling eggs. I did the same with my tomato plants last year and you could definitely tell the difference. Thanks for the info and I am looking forward to following and learning.
