Dividing Perennials


Many perennials rarely need to be divided, unless they outgrow their space. (Hosta)


Certain perennials will benefit from being divided every 3 - 5 years, especially if the center dies out. (Daylilies, Astilbe)


Sometimes a perennial weed such as grass is in the plant so badly, it needs to be dug out and weeded.


Fall is a great time for renovation work, and bulbs can be planted at the same time.

Growing Perennials from Seed






Collect seed from your perennials on a dry day, store in paper bag is ideal


Perennials for shade tend to not set as many seeds (Columbine does)


Allowing your perennials to set seed weakens them, so if you are not going to collect seed, deadhead!



Many perennials that grow well from seed can be planted right away, either where you want them to grow, or in a nursery bed (like a row in the vegetable garden). They can then be dug out and replanted in the border the next year.







Cuttings and Layering



Growing plants from cuttings does require a fair bit of moisture, but certain plants can be grown that way. Layering is similar to cuttings; however the cut is not made until after the roots have formed.




Low alpine plants can be invigorated without dividing by adding good soil to the center of the plant, usually after they flower in spring.
