• Are the trees displayed in water?
• Is the ground or mulch wet from periodic irrigation?
• Are the trees displayed in a shady area?
• Does the store receive multiple tree shipments? The more deliveries the better because it reflects a later cut date or at least longer (cooler) farm storage.
• When you examine an individual tree you can also look for several characteristics.
• Is the tree heavy? If it is, it is probably heavy with water. If it is light, it is dry.
• Is the foliage cool to the touch? Again, a cool tree is a moist tree. A dried out tree will feel warmer.
• Are the needles soft to the touch? A dry tree will have stiff, sharp needles. The exception to this rule are the spruces which naturally have stiff, sharp needles.
• Are the needles a rich, dark-green color? Dry trees are often bleached-out to a lighter olive-green or grey-green.
• Do the needles stay on the tree? This can be misleading as older needles back inside the canopy of the tree closer to the trunk will shed on even a moist tree. However, needle shed on a cut tree should not be extensive and needle loss on the most current growth on the outside of the tree indicates a problem.
• Are the needles fresh? Very fresh needles are will snap when bent like a fresh green bean. Somewhat dry needles have lost their plumpness and will bend rather than break (like a rubbery, stale green bean). These needles will still take up water if provided. These stressed needles are also most likely to naturally drop if the tree is not fully dormant. The driest needles are so brittle and stiff that they easily break when branches are brushed and leave a broken stub on the branch they came from.
• Is the cut stump sticky with sap? Examine the bottom of the tree where it was cut. If the stump is sticky, that’s a good sign that the tree is still fresh.
