It has been nearly nine months since the weatherman made his predictions about the winter of 06-07. I don't remember what he said. Do you?
The groundhog spoke in February, with surprising accuracy, and must be assigned some responsibility for current garden problems besides eating plants.
Personally, I prefer to wait at least a month after it ended to offer my predictions for the previous winter. It gives one time for analysis and usually yields quite accurate results.
A recent conversation with a person tied to one of the area's large public gardens confirmed what I have suspected. Last winter was strange. Plants that should have survived were killed. Plants that you would expect to have suffered, seem to have survived with little damage. He called the winter weird and I agreed.
As you remember, it did not get cold until early February. I planted some things in January and I have had numerous reposts of others doing the same with success.
The most unusual report was from someone who was given a holly as a Christmas decoration. After Christmas, he planted it. It survived and is happy. A few feet away an established similar holly died.Plants refused to assume full dormancy last fall and the juices or water in the stems of many shrubs and young trees froze when the temperatures turned abruptly colder. Look for a vertical crack in the lower stem as evidence. This usually is fatal or at least weakens the stem and shortens the life of the plant.
The winter was also quite wet. Days after I wrote about rhododendron problems I was asked about them. I quickly handed the person a copy of the paper and improved my creditability when they realized that I had written the article.
Anther report was with iris with wimpy new growth. A few questions later I suggested that they were too wet and that removing some of the mulch around them might help. The last report I had suggested that things were improving after pulling back the mulch.
I am not knocking mulch, just making the observation that it is sometimes poorly used. Mulch cools the soil and holds the moisture. That is great in a hot, dry summer but can cause problems with root rots during a wet winter and cool, wet spring.
When you mulch, delay spring applications until it has warmed. Since no one is going to do that, let's suggest that you reduce the depth and keep the mulch away from the plant stems. Fungus love moist stems and, besides, an inch or two will give the same results as four inches. One could ramble on but I think you see my point. It is a lot easier to predict a winter after it is over.
