What is your best method for winterizing

1. Endless Summer

2. Climbing Hydrangea vine

3. Don't know the name deep pink color, no flowers this year.

Please give me some help with your tried and true methods. Last winter in Ontario was great for the roses but not the Hydrangeas.

Hello, Mary Anne. You can view information on winterizing hydrangeas on the thread by hayseedman that the link URL below will take you to.

Additional information for each of your hydrangeas:
* the official website for the Endless Summer Series now suggests applying winter protection techniques in Zones 4-5 so consider protecting the ES too if it has been an unreliable bloomer for your garden.
* for climbing hydrangea (h. petiolaris), you can apply lots (3-4 inches or 7.5-10 centimeters) of mulch way past the drip line. They develop an extensive and long root system that one really cannot track under the ground so protect the roots a little past the drip line and leave it at that.
* for the 3rd hydrangea, the unknown one, apply hayseedman's winter protection techniques.

General suggestions:
* do not fertilize starting on August-September. This prepares the plants for dormancy and does not result in new growth that will get zapped by early frosts.
* maintain about 3-4 inches or 7.5-10 centimeters of any type of acidic mulch up to the drip line
* watch your watering. Temperatures are not as hot as during the middle of summer so you may be able to reduce the watering (amounts and times a week). If not sure, use the finger method for one or two weeks: insert a finger to a depth of 3-4 inches or 7.5-10 centimeters & water if it feels almost dry or dry; mark the date when you watered on the calendar; when you notice a pattern developing (you water every 2/3/4/5 days, set your sprinkler to water on the same frequency. Stop watering when temperatures go below freezing but water once every two weeks if the temperatures remain warm and the plant goes dormant.
