Help, perennials, everything is dying/wilting!
I'm not a big gardener but I recently filled raised beds with new compost and then fresh topsoil on top, I bought around 10 plants, wanted cheap and cheerful perennials that would just regrow and flower every year. I watered them every other night for the first week I had all the plants, however went away for a week (it rained over this period). Everything has been in slow decline since I planted even though everything recieves ample light and water, flowers are disappearing and more dead heads arising, when I gently take away the dead heads nothing seems to grow back!. I know it is hot recently so I have been watering everything every night in order to try and get them going. The latest casualty was the supposedly hardy sunflower! I planted three have watered every day and the sun has been glaring on them all day on the sunniest side of the garden and even they have started to wilt! My hanging basket has virtually died aswell, not sure what I am doing wrong, have tied both overwaering and underwatering too. Here are some pictures showing how bad everything has got.
