Cut trees should be purchased as close to Christmas as feasible and should be as fresh as possible. The best way to do this is to visit a Christmas tree farm where you can select and (sometimes) even cut your own tree. Keep the cut base in water in a bucket, and top up the water as often as necessary. Spray the cut tree with Yates DroughtShield. This is an anti-transpirant that reduces water loss from leaves and has been found to keep the cut tree in good shape for considerably longer.
The most traditional of all potted Christmas trees is the European spruce (Picea abies). Hundreds of these are sold each year, only to languish and die in neglected back corners. Presumably anyone who buys a living tree is keen to keep it alive, so it’s best to put a bit of effort into post-Christmas care of a potted spruce.
If the spruce’s pot is relatively small (25cm or less) the plant should be re-potted into something larger. This will help it to survive through the rest of the long, hot summer. Use a quality potting mix such as Yates Blood & Bone and apply some Yates Waterwise Soil Wetter to the mix after potting. Give the plant a settling in treat of Yates Dynamic Lifter Liquid and, a couple of weeks after potting.
