Fertilize with low-nitrogen, high-phosphorus fertilizer to encourage more blooms and less foliage. Most perennials do not need heavy fertilization. A single application in spring (after the soil has warmed) is usually sufficient. Mulch around plants to keep weeds to a minimum and retainmoisture.
Should you cut back hydrangeas in the fall? Fall BloomingPrune in late winter and early spring. Prune as far back as you want right above the first leaf joints. It will grow from that point onward, getting larger each year. Read more about pruning hydrangeas, and learn whether your shrub blooms on old or new growth in “Pruning Hydrangeas” by Janet Carson.
Should I fertilize my perennials? Perennials may benefit from a single fertilizer application just before or at the time that new spring growth is pushing up. The most common recommendation is to apply no more than 1 pound of nitrogen per 1,000 square feet if no compost is used. Do not fertilize perennials in the late summer or-fall.
Do perennials die in the winter? Perennials die back in winter. In colder climates, most perennials die back (though there are some evergreen perennials). In warmer climates, they may just go dormant. Since you only need to plant them once and enjoy them for years, perennials are the backbone of any garden or landscape.
Do you cut back perennials in fall or spring? Cutting old and diseased foliage in the fall helps a perennial jump right into new growth come spring. But some plants need their foliage for protection over the winter and instead should be pruned in thespring.
