What's as tall as the Leaning Tower of Pisa and can live for over 600 years? Pinus nigra! This tree of exceptional size and longevity grows naturally in North Africa and southern and eastern Europe. Undemanding, it adapts to most gardens, without ever leaning!
How to recognize black pine (Pinus nigra)?
Pinus nigra is a conifer that can reach heights of over 50 meters at maturity. When young, the tree has a pyramidal habit. As an adult, it has a rounded crown.
The straight trunk reaches six meters in diameter. It is covered with cracked bark. The color varies from yellow-brown to gray, depending on the region.
Foliage color also depends on area of distribution and variety. It can be yellow, gray-green, as in laricio Pine, or dark green, as in austrian Black Pine. The needles are supple and not prickly, sometimes measuring over fifteen centimetres. They are inserted two by two.
Flowering takes place in spring. The ovoid male catkins, loaded with pollen, are located on the lower part of the tree. The female flowers hatch at the top. Pine cones are five to ten centimetres long. They bear rounded scales and winged seeds.
Like other firs, Pinus nigra is non-toxic. And since its needles don't sting, you're in no danger!
Our maintenance tips
Think carefully before planting your Black pine. Once installed, you won't be able to move it.
Watering
Feed your Black pine only when the substrate has dried thoroughly (at least five centimeters). Water generously with room-temperature rainwater and let the excess run off through the drainage holes.
Drain off any stagnant water in the dish or planter. It will rot the roots.
Spray
Your black Pine hates wet foliage. You must not mist the plant.
Repotting
Get a perforated pot. You can place a bed of clay balls or gravel at the bottom to improve drainage.
Mix a few handfuls of sand with universal potting soil. Pour a layer of this mixture into your pot and plant your Black pine. Add substrate and pack lightly.
Water to help roots take root and expel air bubbles.
Fertilization
To promote the growth of your Pinus nigra, apply fertilizer in spring and summer.
Fertilize your Black pine with a conifer fertilizer once a month. Follow the dosage and manufacturer's instructions to avoid damaging the foliage.
Prune
Your Black pine does not need pruning. On the contrary, pruning could be detrimental to its growth.
You can, however, remove dead branches in early summer using a clean, sharp tool, such as pruning shears.
Plantation
When the risk of frost has passed, it's time to plant.
Choose a sunny, isolated location. Black pines can reach several dozen meters in height when fully grown, and its deep root system can compete with other species.
Soak the rootball to rehydrate it and dig a hole at least twice as big. Remove stones, weeds and roots. You can add sand or compost to improve the soil.
Plant your Black pine. The top of the rootball should be level with the ground. Fill in the hole. Water generously toencourage rooting.
Seedling
Your seeds are more likely to germinate if you stratify them cold.
Fill an airtight bag (e.g. A freezer bag) with potting soil for seedlings and plantations. Moisten the substrate. Bury your seeds in the potting soil, close the bag and place it in a place where the temperature is between 0 and 5°C for three weeks (refrigerator, garage).
Check your seeds regularly to make sure the potting soil stays moist and doesn't rot. As soon as a seed germinates, you can plant it.
Fill a tray or bowl with seedbed potting soil. Plant your seeds about a centimetre deep, pointing downwards.
Place your seedlings in a bright spot, but not in direct sunlight. The temperature should be at least 15°C.
