Heat Affecting Tomatoes
My Brandywine, Brandy Boy, Big Beef, and Gurney Girl plants are
producing in abundance, but not turning red yet. However, the Cherokee Purple and Black Krim are not doing as well, with many blossoms and few setting. It's been well into the 90°s with RH running between 7% and 44%. The heat has caused some drooping of the Cherokee Purple leaves, so I give them some extra water, and cover the cages with old bed sheets during the heat of day. I'm in metro Denver where we usually have a short season. On Aug 1, I snip-off the new growth and blossoms that have not set, and hope for a late frost. |

Heat Affecting Tomatoes
From my own experience, I have no problems growing Cherokee Purple
and Black Krim here in the Chicago area. One culprit might be your nighttime temperatures. If they are not at least 55 degrees, the tomatoe plants may not set blossoms. Here is a web site where someone tried to correct that problem: http://gardeneryardener.blogspot.com...ty-tomato.html Also, I'm finding information that suggests Heirlooms are late to set blossoms, but I have not found that in my garden. You can also try growing some of these difficult tomatoes in pots, which you can move to shady cool places during a heat wave.

I have grown Black Krims along with Black from Tula, and Paul Robesons. I prefer the Krims over the other "black" tomatoes, could be my soil. I concentrate on heirlooms and have found that while the fruit is far superior to hybrids, yields on many of them are reduced, but I prefer to have fewer tomatoes that are far better tasting. I also grow White Tomasil every year. Heavy yields for an heirloom, cream/white flesh, lower acid. Large fruit. Unless you prune, I have found that the indeterminate heirlooms get so danged tall that moving them about would be impossible. I have them trellised and tied and wrestled to seven feet and then often sideways, and then they go downwards anyway, and the only thing that stops them is frost. I agree that growing them in pots is a good thing. I experiment with amounts of sunlight on them and am finding that some tolerate partial sun quite well, while still producing well. I have better luck with the cherry types than standard. As far as setting blossoms, and fruit late, again, it may depend upon the variety. Some also take much longer to ripen. Anyways, I quess, I'll se ya round the next organic dissed-cussing! ;-) Chicago, eh? My dad was born and raised in Elmwood Park. Left home, or tossed out, never sure which, had something to do with a girl of the wrong religion (not mom) at eighteen and never looked back. Hell, I'm developing a certain fondness, or fascination for/with ya', old boy. Care Charlie mark that up in history folks............they are agreeing on something! the world must be coming to end soon........ lol |

Tomatoes would prefer 50% to 70% RH and would like a temp a little less than 90 F. Late season tomatoes always seem to take forever to set. Tenting sounds good. Anyway to get standing water under the plants (kids pool, cookie trays with water, ?) to raise the humidity? I would try misting, usually not a good idea with tomatoes but at 7 - 44% RH, hey. -- Billy http://angryarab.blogspot.com/ |
