Basil

I bought the herb 'Basil' recently and all seemed well until about 5 days ago. I'm unsure what situation/soil.watering they like. Can anybody help? Obviously I'm doing something wrong. :confused:

 

My outdoor basil is in fairly clay soil and is doing fine, what's wrong with him poppet, is he wilting?

 

Basil is a hot climate herb Poppet and doesn't like too much water.
Best in a sunny position, well drained with a little water now and then.
Hard to guess what's gone wrong without more details.

 

Sadly I can't grow basil here .. unless it's in a shady postion and then I have to water it all the time .. same with coriander

 

I have a basil on my kitchen window sill growing fine, growing in all purpose compost. Have in the past put them on my balcony without sucess same with mint

 

He's definitely wilting. He is sitting in a pot of all purpose compost outside my backdoor along with some chives/celery leaf/lavender/mint and parsley.It gets quite strong sun in the morning until about 2.00pm. The celery leaf isn't looking too happy either though not for the same reason I think-different symptoms(leaves turning brown/tiny black specks near base of leaf. Perhaps I should remove the celery leaf from the other herbs and water 'Basil' less frequently? I've been giving everything in the garden a dose of tomoto feed every so often - could this be the problem?
