For coarse or fluffy mulches such as leaves or pine needles, use twice as much. Be sure to keep mulch away from the plant's trunk to prevent rot due to excess moisture. If necessary, replenish the mulch in the spring. There are two perfect partners this month. The first is the association between daffodils and daylilies.
Daffodils are unattractive after flowering when their leaves have to ripen.
Daylilies, planted in the same area, will hide the daffodil leaves and deliver a nice show of flowers later in the year. I generally plant them two feet apart, with the Goblins toward the front. They tolerate most soils, bloom from late spring to fall, and won't mind a bit if you don't have the time to water them occasionally. Keep the dead flowers cut off, and your neighbors will beg for your secrets. I've really set these off by planting lemon-yellow Halimium occimoides behind them.
