I get this question a lot this time of year. I get my fall rush once the kids are back in school, it takes a few weeks to get through the design process, and suddenly we’re just past Halloween. Is it too late? It depends on what you’re doing.
Woody trees and shrubs can be planted almost year-round in Virginia. With the exception of last winter, I’ve had plants go in – and do well – all winter long. As long as the ground isn’t too hard for us to get a pick and shovel in, we can plant woody trees and shrubs. Perennials are another matter. They are generally too delicate to plant after about November 1st, because we’re pretty certain to get a hard frost after that point. I did a post a while back that talks about safe frost dates for northern Virginia.
Most asphalt companies in Virginia shut down sometime in December, and open up again in April. If we’re redesigning a driveway, we need to keep this in mind.
Concrete & Mortar
Concrete is going to be the happiest when the nighttime temperatures stay above freezing. That’s not to say that concrete work shuts down for the winter. On cold days, my masons have set up tents with propane heaters and laid stone all day long in t-shirts. At night, thermal blankets can be placed on flatwork to keep the temperatures high enough. Pointing up and cleaning can get slowed down a bit because the concrete stays “green” longer, but that’s not a problem as long as the mason knows what s/he is doing.
Pavers (and segmental retaining walls) can be tricky in the winter. The problem happens when you have a significant amount of rain, sleet, or snow on the base or sub-base. If this moisture is allowed to freeze, you can have long-term settling problems. The solution is to keep the area as dry as possible, and use thermal blankets or other means to keep the base material from freezing. Again, the work can be accomplished in the winter, it just requires a knowledgeable contractor.
Ponds and Waterfalls
These can certainly be installed in the winter, but temperatures below freezing can make working with water less fun than on a sunny, 70 degree afternoon.
Decks, Porches, Pergolas
As long as snow’s not a problem, these can be built all year long
And what if you’re just starting to think about the design process? Winter is a great time to start the design process. I’m currently booking December and January projects. If you have a project you’d like to start planning, send me an email and let’s get started!
