rough skin tomatoes

[ALEC090]

the skin on some of my tomatoes are rough they look like they are cracking but not splitting this happens when they are nearly ripe also a lot of the flowers and stems on the plants are breaking off i have lost a lot of the tomatoes like this before they even start to grow you get the flower and somtimes they set and then fall off others dont even set and they drop off also some of them have withered and died and others on the same plant are fine and grow into fine tomatoes they are grown in the greenhouse in individual buckets and in a good compost and get fed with levingtons tomorite any ideas ??? thanks regards alec090

I think the problem may be due to irregular watering ie drying out too much them getting lots of water all at once.
I put the blame on the heat-wave we have right now, its so difficult to keep things on an even keel. Going off at a slight tangent, I expect to see my apples splitting when we do get some rain, thats if they have'nt all fallen off by then.
You may be able to improve moisture retention by mulching with some humus rich compost and watering in hot dry periods, also discard any splitting toms to avoid them becoming infected. Good Luck T bird+

Perhaps the daytime temperature in your greenhouse is just too excessive in all this heat. Some of the flowers on my outdoor tomatoes, which are on a south-facing fence and getting really baked, are dropping off without setting to fruit despite being regularly watered, and I can't remember this happening before.
You may find that if the temperature drops, the flowers will start setting again. You seem to be doing all the right things. Is your greenhouse shaded and well ventilated? You can try spraying the plants regularly to keep up the humidity, which may help.
