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
The time between pollination and fertilization in pine trees is typically around 15 months. This allows for the pollen grains to settle on the female cones, germinate, and eventually fertilize the ovules to produce seeds.
Pine trees produce approximately 260 pounds of oxygen per year.
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.
Because they are a kind of Evergreen.
Evergreen trees like pine trees keep their leaves all year
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.
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 cones typically take two years to mature and release their seeds. In the first year, the pine cone develops, and in the second year, the pine cone opens to disperse its seeds. This two-year cycle allows the pine tree to ensure successful reproduction.
