Perennial Care--Five Tips for Fall
Simply by fall, most perennials are through blooming and by you might be ready to throw in the towel, but there are still a few tasks you need to do to ensure that your perennials survive the winter. Follow these guidelines on this checklist, and you should come with an even better perennial garden next spring.
one particular. Make "action" notes. Ahead of you forget what crops should be divided, what should be moved and where, and what you need to do to certain plants next season, write it down now.
2. Should perennials be cut back now? This depends. Should you normally get little snow, you may want to leave them until spring, so the stems can trap the snow. If you have perennials with attractive winter interest such as Sedum 'Autumn Joy' or decorative grasses, you may wish to leave them for winter effect. Some seedheads, such as Black-eyed Ann, may provide food for birds. If your perennials are diseased, you may wish to cut them back and destroy--don't compost--the diseased stems and leaves.
Often gardeners in chilly climates with short months have more time for cutting back in the fall than spring. The moment cutting back, leave a number of inches of stems to help trap the snow. If cutting back high ornamental grasses such as Eulalia (Miscanthus), cut back again a foot or more above the ground as this part of the shoot often has next year's growth.
3. Carnations. Many gardeners have questions on overwintering these, and for more detailed information should check with other articles, books, and their garden centers on this subject matter. Some tips include making sure grafted roses have graft union below surface a couple of ins, or are covered with soil; mulch only with soil if you have rodents, not with hay; and cut back only to top of mulch. Or plant some of the many hardy plant roses. There are both new and old kinds on the market that require little or no protection.
4. Cover or mulch. This depends in part on your beliefs. Mine is the reality perennials should be able to survive with the summer time mulch--a couple inches of bark mulch, shredded leaves, or similar material--or more put in a steamy microclimate site, put in pots to winter inside your home, or maybe not grown. Various other gardeners don't feel this way, or have special perennials, whereby the guideline would be to add more winter mulch.
A foot or more of loose organic and natural material such as straw can be used. Avoid using hay as it often contains fragrant weed indian weed cavendish fid negro head old seeds. And don't use such mulch if you have rodents, as this only provides them with a home with your perennials as their winter food supply. Apply mulches late, around mid-November in the North, as perennials need some cold to harden properly. Remove mulches as early as possible or when snow melted ; melted, molten melt. In the North, this should be done at least by April you and through a period of several warm times. Leaving mulch on too long will lead to tender and weak progress as perennials grow under the mulch.
If you don't mulch your perennials during the growing season, you may want to provide a light part of a couple ins of mulch for winter protection as mentioned above. This will provide 5 to 10 examples of temperature protection to the soil in fall and spring, which may imply life or death for certain perennials at a time when they are least hardy. And even a light layer of mulch helps prevent vast temperature fluctuations with icing and thawing, which destroys roots. Such organic and natural mulches, naturally, will break down, adding essential organic and natural subject to the soil, and help conserve moisture and reduce weeds during the growing season.
5. Produce new beds. If you want new perennial bed frames by spring, fall is a good time to start. If in hay, cut back low now. For sodded areas, line off sod with a rented sod cutter. Or perhaps you can use a herbicide to kill the grass. Or you can just cover with dark-colored plastic, and almost all of the grass will be useless and composted by springtime, and simple enough to seed. Test soil and add lime now if needed.
Other items in the fall checklist include examining and labeling plants as needed, putting out blocks for rodents, digging young summer bulbs, checking show up fertility and adding fragment, and making cages for next year's tall perennials.
