We've nearly finished clearing all the weeds away from our new garden. Just wanted to get some advice on what to grow and when. I have bought some bulbs (alliums and tulips) - am I right in thinking it's too early to plant the tulips?

I also want to buy a few shrubs. When is the best time to plant decidious shrubs (such as Cotinus Grace) and evergreen shrubs (considering a berberis possibly). Can they be planted along with any new herbaceous perennials now, or is it better to wait until spring?

Thanks
