Self pollinating my tomatoe plants?

Question

Ok so i just asked the question about "do i really need to use a que tip to pollinate my tomatoe flowers myself" becuz they keep falling off. I got a couple of good answers but let me clarify..these plants ARE outside, they DO get watered enough (we've grown them may times before) and how the heck do i distinguish a female from a male plant to cross pollinate them myself? Then i got an answer that most are "self pollinating" so it's not that importnt. I'm stumped. So I was even told that since they are 6 ft. (approx) tall they may be too big. So do I go ahead and top off the top and make them smaller? I just went outside and tapped them as I was told. We'l see.

Answer 1

all they need is for the humidity to be raised, at night spray the flowers with water, and make sure you feed the plants every 10 days or what it says on tomato feed bottle

Answer 2

Most tomato cultivars are self pollinating but you can help them if you like.  You don't need a Q tip or paint brush.  Simply tap the stem at the base of the blossom with the back of a fingernail to gently "rattle" it  and shake the pollen loose.  

Sometimes if the daytime temps are too high, consistently in the ninety's, the blossoms will fall before setting fruit.  That is a survival technique of the plant under stress. Or a big fluctuation between night time and day temps will have the same result.  You already said they are getting enough water so that isn't the problem The height of the plant has nothing to do with the blossoms falling off.  Unless for some reason you can't reach the tops, cutting them back just reduces the number of tomatoes they will produce.
