The answer will depend on which bulbs you were growing. For example,
\ndaffodil stems should not be cut back until at least 6 weeks after the
\nflowers have faded, and you should never tie the foliage in knots or
\nbraid it (this is a common but ill-advised habit). You can leave
\ndaffodils in the ground to naturalize and spread.<\/p>\n

With tulips, you also need to wait at least 6 weeks from the fading of
\nthe flowers before cutting back the leaves.<\/p>\n

With hyacinths, you can pull away dead foliage and flower stems as they
\nfade. When the top growth has died down, you can either leave them in the
\nground or dig up the bulbs, dry them off, and store them for replanting.<\/p>\n

If you are growing iris, you can cut the dead flower stems to the base,
\nand cut away dead leaves in the summer. If they are bearded iris, the
\nfan of leaves may be cut back in the fall to about 8 inches above the
\nbase.<\/p>\n

You can certainly plant your annual petunias quite close to bulbs like
\ndaffodils and tulips and other bulbous plants which are quite vertical.
\nJust don’t plant right on top of the bulbs. To disguise dying bulb foliage, use perennial ground cover plants that keep their leaves over the winter, and that have stems soft enough for bulbs to emerge through them. Hardy geraniums (true geraniums, also called cranesbill) and creeping veronica, such as Veronica peduncularis<\/em> ‘Georgia Blue,’ are good choices. You can remove dried leaves as needed, and they can be tidied or groomed in early spring.<\/p>\n","protected":false},"excerpt":{"rendered":"
