Providing winter hospitality to both vertebrate (birds mammals, lizards, etc.) and invertebrate (insects, spiders, worms, etc) wildlife is an important consideration when tidying the garden at the end of the season.

When you collect plants, it is rather useful to label and record everything added to the garden. I wish I had started sooner. I did not do this the first few years of starting my current garden, so many of my oldest plants are unknown down to cultivar and remain unlabeled. After a few years, I began making an effort to include a metal identification tag with a waterproof label with every plant that went in the garden as well as creating a spreadsheet I could print the labels from using a label maker.
