So far, it's looking like a very good tomato year. For several years, I've had to completely enclose my tomato plants with netting to keep squirrels and birds away. Years ago, neither was a problem. Now I see many home garden netting or wire enclosures because of these critters or for deer. I'm fortunate that I haven't had to contend with deer, but if I lived just 4 blocks away, they would be a big problem for me. I have 2 blocks of 6 tomato plants. I put in green 8' poles and top each pole with a tennis ball to support the netting. I use two 14' x 14' pieces of netting to enclose each block of 6 plants. There's a 2' high chicken wire fence around them which the netting drapes over. It's a PITA but it works. The 2' of chicken wire also keeps out rabbits which would otherwise devour the bean and pea seedlings. (I plant bush beans between my tomatoes. They produce a decent crop before being shaded out by the tomatoes. I love the French variety Maxibel.
I've got a total of 12 tomato plants and am growing 8 different varieties of tomatoes. Here are 7 of them. Clockwise from the upper left corner they are Big Beef, Lemon Boy, Chef's Choice, Enchantment, Sungold, Sweet Chelsea, and Golden Rave. I've chosen them all for their taste and productivity. I'm trying 1 new variety this year, Purple Boy, but none of those have ripened yet.
I don't grow heirloom varieties. Each time I've tried, the yield on my heirloom plants has been abysmal. Lots of lush foliage but few tomatoes. Anyway, hybrids bred for home gardeners are crosses of heirloom varieties, so their flavor is just as good, IMO.
