Why are my potted plants wilting?

I have some potted plants (2 patio tomato plants, 2 strawberry plants and a potted zinnia) on my patio ledge where they have plenty of direct sunlight. I can't figure out why they are wilting! I believe the strawberry/tomato plants may just need to have a bigger pot and bought some bigger ones today. If I don't put them on the ledge, there isn't a lot of sunlight. If anyone has any suggestions or can tell me what I'm doing wrong please let me know. I'm still new to this gardening thing! Thanks for your help!

Why are my potted plants wilting?
because your not giving them soy sauce
Reply:The patio tomatoes will need at least 10" pot per plant


A larger pot 12-14" will give you more fruit.


use a good quality soil


(such as miracle grow with moisture additive)


temperatures need to be above 45 at night for zinnias ,


if the pots are clay, soak thoroughly


if plants are kept too wet they will also wilt


so be sure the soil is actually dry when you water


and all containers need to have drainage holes.
Reply:its your soil...give them good soil and holes in the bottom of the container then water everyday they will grow just fine...dont forget to fertilize.
Reply:Use five gallon buckets for pots, drive several holes in the bottom, put some gravel in the bottom where the holes are, and then fill the bucket to about three inches with good loose loam then watter frequently.You will be hard pressed to have a crop failure this way.
