In mid-November it is time to cut or fold the most summer flowering perennial or fall, just take a quick glance eye in the massive offering a sad spectacle: All flower stems and much of the foliage yellowed or worse, they withered away.
This indicates that the perennials have completed their growing cycle for the current year and become dormant (Term for dormancy). The sap is concentrated in the roots, aerial part dies, leaves the base, it can remain persistent for some species. This distinction is important to operate the cleaning. It's a big job but it is essential to the sustainability of the perennial garden, also all very robust.
today looks like a solid corner that I failed to clean, it is understandable that the transaction size, it also frees space for 'years following the shoots also obeys an aesthetic concern, the vacuum is ultimately preferable:
Before the fall cleanup, 11 / 2010 Depending on the species, so I flap my perennial vegetation more or less severely.
Asters, solidagos, helenium, large yarrow, fennel, sun perennial gardens and chrysanthemums are folded at the strain level, just cut all stems at soil. The leaves, deciduous, does not reappear until the following spring .
I eliminate the foliage of daylilies which often collapses and rots due to moisture being careful not to damage the new shoots which emerge already :
Daylilies, 11/2010 gaur with woody stems are difficult to cut, are cut severely, I do not let that young green shoots.
I do not touch the evergreen and fulgida Rudbeckia nitida deamii, I cut at the stump all stems floral
Rudbeckia nitida , 11/2010 Rudbeckia fulgida
deamii, 11/2010 I save the deciduous anemones of Japan, it is still green. It does grate that later, often in December. That of COQUELOURDE, silver, still beautiful all winter and requires no care:
Anemone Japan, 11/2010 
COQUELOURDE, 11/2010 For sedum, I do nothing until March, I leave stems and flowers in place, they will dry and be very decorative in winter frost or snow
Sedum, 11/2010 I cut the foliage of herbaceous peonies, leaving only 10 cm of stem, it is often the vector of fungal diseases .
I leave intact the foliage of spring flowering perennials such as peach-leaved bellflower or julienned ladies, is to deprive the elimination of the spring bloom .
For lady's mantle, I am content to remove from time to time during the winter dry leaves, the foliage is more or less persistent depending on the severity of the winter: 
Giulia ladies, 11/2010 
Peach Leaf Bellflower, 11/2010 
Alchemilla, 11/2010 There would also be much to say about how I treat the less hardy perennials. I will come back probably.
