It is best not to fertilize pine trees, as all they really need is mainly sunshine and water. At most add only a tablespoon of balanced fertilizer to the dirt and then water to let nutrients reach the tree.
once a year, annually, in fall/autumn
A granulated citrus formula, applied to trees three times a year, can help fertilize your palm trees. You can do more research atforums.gardenweb.com/forums/load/.../msg0314253717808.html.
Pine trees do not lose their leaves in Autumn. They are tall trees that have string like leaves and have cones on them. The cone are called 'Pine cones'. The look relatively the same all round the year.
I think pine cones tend to grow every other year on pine trees, and i notice every other year they're will be 3 or 4 on one branch.
Evergreen trees like pine trees keep their leaves all year
Because they are a kind of Evergreen.
spruce or pine trees are always have green pine needles and brown bark all trough out the year. While birch and willow trees their bark turns a more whitesh brown.
in the fall. most trees loose their leaves in the fall.
Evergreen trees keep their leaves on all year around. Some trees that are commonly found in evergreen forests are poderosa pine, incense cedar, sugar pine, and douglas fir. Pine trees have needles and pine cones. Squirrels, foxes, wolves, coyotes, owls, and eagles live in the forest.
The growing season for pine trees is Spring to Autumn (Fall, in the USA). There is little, if any, growth during Winter. Unlike broad leaf trees that shed their leaves and shut down for Winter, pine trees continuously lose and replace individual needles throughout the year.
Examples of needleleaf trees include pine, spruce, fir, and cedar. Needleleaf trees are characterized by their long, thin leaves in the shape of needles, which remain on the tree year-round. They are typically coniferous trees and are common in colder climates.
Pine trees are considered an evergreen. They shed needles like other trees lose their leaves, but never all of them and only after the second growing year. Hence the name evergreen.
