When the soil crumbles nicely in your hand, then it's time to go plant the new lilies and hostas and other hardy perennials and bulbs. Until then, a good way to pass the time is in taking an informal inventory of the garden. Right now you can see where there are plenty of bulbs, and where there are bare spots. Make a note of that - you'll be glad that you did when fall rolls around and you're wondering how many new bulbs you need. And this is also a great time to look at the bulbs and decide how you are going to camouflage the ripening foliage when their season is done.
Many people use hostas to hide that yellow stuff.
You may not see yours yet because they tend to be late-risers. But when they do emerge they will grow into a lovely cover for the ugly yellows. If you haven't found a good way to conceal your own bulbs give hostas a try. A combination of white daffs with green and white hostas such as 'Revolution' , Patriot is lovely - especially if you use late blooming daffodils and tulips, which will be in flower when the green and white of the hostas begin to unfurl. Pair yellow daffodils with the green and gold of Hosta 'Twilight.
