My lavender wasn't getting on well in its previous spot in the garden (although it was at least the right colour!). so I dug it up and put it in a little pot, then put it in a bigger pot with some compost with food in it. I give it a good watering every evening but it's dying off. Am I not watering it enough? Wrong spot? It's in a nice sunny spot on the patio. How am I managing to kill it? Oh and I've given it a real soaking tonight which is why the dirt is so dark
