How do trees make sweet edible sap in spring? At the end of winter, sap of temperate broadleaf eudicot trees provides energy-rich sugars for animals and peoples of North America. Here, I conduct a multi-disciplinary synthesis to elucidate a theory of sap production and movement at a 'whole...

While trees store substantial amounts of nonstructural carbon (NSC) for later use, storage regulation and mobilization of stored NSC in long-lived organisms like trees are still not well understood.At two different sites with sugar maple (Acer saccharum), we investigated ascending sap (sugar concen...
Over the winter, a deciduous tree will produce sugars and energy for the growing season ahead. It will weigh more at the end of winter because it has drawn copious amounts of sap into its limbs for storage. Once spring emerges, this sap is used as nutrients to grow leaves. How To Calc...

Scales damage trees by piercing leaves, feeding on sap, and leaving sticky excrement. Scale insectsare similar to aphids in the type of damage that they inflict. These small, armored insects pierce the leaves and feed on the tree’s sweet sap, leaving their sicky excrement behind. Scale has...
Tree sap, whether it be pine or another variety, can easily drop onto cars while parked on the street or the driveway under a canopy of trees. Once that sap gets hot, in the sun, it basically bakes on and can be very difficult to remove. ...
A fine mesh strainer to remove bugs, bits of bark, etc., from the sap How to tap the trees Drill a hole in the tree about about 1.5 to 2 inches deep, depending on the thickness of the bark. Be sure you are angling slightly upward, so that sap will flow downward and into the buc...
