The stone pine, known by the scientific name of Pinus pinea, is a conifer found throughout the Mediterranean region, especially in the south of the Iberian Peninsula. But, despite being very common, it has a quality that makes it a very interesting plant to have in the garden: its pine nuts, which are edible.

In addition, it withstands salinity, so that it can be planted near the coast (or even on the coast itself).

Origin and characteristics of the stone pine

Our protagonist is a conifer that grows up to 30 meters in height, known by the common names of Manso Pine, Doncel Pine or Stone Pine. It has a slow growth rate, but a very long life expectancy: up to 500 years.

It is characterized by having a more or less straight trunk, which has grayish plates separated by reddish cracks. Its crown is rounded and flattened, so it gives very good shade. Its leaves, called needles, are thin and green.

The fruit is an oval-spherical pineapple between 10 and 15cm in length that ripens in the third year. Pine nuts are covered by a hard rind, and they are edible.

How is it cared for?

 

If you want to have a stone pine in your garden, keep the following in mind:

Location

It is a tree that has to be placed outside, in full sun. Because its roots are long and strong, it is important that it is at least ten meters away from pipes and others to avoid problems.

Earth

It depends on where you are going to be:

  • Garden: it must have good drainage, being able to grow in sandy soils, and even a few meters from the sea. If the soil has a tendency to compact and also has problems draining the water, it is advisable to make a hole of 1m x 1m and mix the soil with perlite or some similar material in equal parts.
  • Pot: it is not a plant that can be kept in a pot for many years, but during its youth it is precious in a container- This must have holes for drainage, and be filled with universal substrate.

Irrigation

It withstands drought quite well, but is grateful to receive water from time to time. For this reason, it is highly advisable to water it regularly, about 2 times a week, or 3 if the summers are extremely hot (temperatures above 35ºC) and dry.

Anyway, if it is going to be in the garden, it will be enough to water it the first year, since from the second year on, it will have developed a root system that is resistant enough to be able to live in conditions as long as a minimum of 300mm of precipitation falls in the area. year.

Multiplication

It multiplies by seeds in spring. Let’s see how to proceed:

  1. First, put them in a glass of water for 24 hours.
  2. After that time, keep only the ones that have sunk, as they will probably germinate.
  3. Then, fill a seedling tray with universal substrate and water.
  4. Next, place a maximum of two seeds in each socket.
  5. Afterward, sprinkle a little sulfur to repel fungus, and cover them with a thin layer of substrate.
  6. Finally, place the seedbed outside, in semi-shade.

If all goes well, they will germinate in about 15-20 days.
