Why is my basil wilting?

I have it in a container by my kitchen window. I repotted it after buying it from the garden centre a few weeks ago and initially it was doing well. I have been pinching leaves from the top and I have not allowed the soil to dry out. The soil is still moist at the moment so I cannot rewater - however the basil leaves are still wilting. I have also used miracle grow plant food in the potting mix. What can I do to remedy the problem? Or what if anything have I done wrong?

You do not pinch basil from the bottom as mentionedhere..You pinchthe tops off as soon as you see the two new sets of leaves foring right under it..this then shoots out into two new tops..then you pinch the two new tops off as soon as they set a new pair of leaves underneath them then creating 4 new shoots coming up..Your problem may be 1 of 2 things... The drainage in the pot is not proper and basil do not like "wet feet"..They don't mind slightly damp but not wet... Another may be that you have the basil so close to the window or at an angle that the sun is magnifying so intensely through the window..you are possibly "frying " it..
Reply:Overwatering.But recently the basil growers have been struggling with a fungal root illness and this is the likely cause.It stems from the seeds being sown too close together.nothing you can do,except seed some yourself as it's perfect time
Reply:Basil do not like their leaves sprayed when watering, just moisten the soil.
