Fertilizing perennials in the Fall?

Gail
by Gail

I recently read an article that recommended applying 0-20-0 granular fertilizer to perennial beds to strengthen roots for winter months and supposedly healthier plants in Spring.


Has anyone tried this and seen a difference in Spring growth?

    Hello Gail, Yes - I've been doing this for the past 3 years and noticed a substantial difference in Spring growth and overall health of my perennials.

      Good to know! What zone are you gardening in?

    Don't do it....it's too late now ! ....your plants are going into dormancy and applying fertilizer now may force them back into growth which will be too soft and sappy to stand through the winter....and will be a haven for aphids......clean beds of all dead leaves and debris then apply at least two inches of mulch, composted bark or leaf mould to protect the roots of your perennials....as the mulch breaks down it will feed the soil and plants.....and they will be a lot stronger.....in the spring you could spray a tomato [yes really !] or rose feed to encourage flowers.
