the photos aren't clear enough.
what is the issue with the ants?? ants are all over the place - they're not something you can really get rid of...and probably shouldn't anyway (they can be very beneficial in some ways). they're not going to do anything to any of your
plants - except walk all over them that is
are your
plants getting proper water and sun? are they planted in the correct type of soil?
plant growth can vary...sometimes they have a lot of fruit
growing and sometimes not. they might not be established enough to be producing lots of fruit or they may not be getting the correct combination of water and sun light. they might need a touch of food too...
tomatoe and
pepper both need lots of sun to grow well. and they need regular watering.
it's never a good idea to randomly start spraying chemicals around...
this is a great forum, filled with people with some really terrific knowledge!! make the most of it by posting questions about what's happening...
i'd really hate to see you go overboard with something and end up causing real damage to your garden!!
