Pines (Pinus) are a genus of light-demanding conifers in the pine family, with roughly 110–120 species, recognisable by needles in bundles of two to five. Scots pine, mountain pine and bog pine are native to the Czech Republic. Scots pine is the country's second most widespread forest tree after spruce.

**Pine (Pinus)** is a genus of coniferous trees and shrubs in the pine family (Pinaceae), comprising roughly 110–120 species found almost exclusively in the Northern Hemisphere. Pines are most easily recognised by their needles, which grow in bundles (most often of two, three or five). Three species are native to the Czech Republic: **Scots pine**, **mountain pine** and **bog pine**. Scots pine is the second most important forest tree after spruce and thrives in places where other trees would barely survive.

## How to identify a pine

Among other [conifers](https://www.stromyvcr.cz/en/conifers/), the pine is unmistakable thanks to the arrangement of its needles. [Spruce](https://www.stromyvcr.cz/smrk/) and [fir](https://www.stromyvcr.cz/jedle/) have single needles, while [larch](https://www.stromyvcr.cz/modrin/) carries them in dense clusters of 20–40 and sheds them in winter. Pines have needles in small bundles wrapped at the base by a papery sheath.

- **The number of needles per bundle** is the key identification feature. Two-needled pines include Scots, mountain and Austrian pine. Three-needled are ponderosa pine and pitch pine. Five-needled are eastern white pine and Swiss stone pine.
- **Cones** hang down or stand out from the branch, have hard woody scales with a thickened tip (apophysis) and fall off whole. Fir cones, by contrast, disintegrate on the branch.
- **Bark** on older trees is deeply furrowed. Scots pine has distinctive orange-rust, thinly flaking bark on the upper trunk.
- **The crown** of young trees tends to be conical, broadening with age and often becoming umbrella-shaped or irregular.

### Flowering and cone ripening

Pines are monoecious. On a single tree you will find yellow male cones clustered at the base of new shoots and tiny red-purple female cones at their tips. During flowering in May and June so much pollen is released that it coats puddles and cars, which people call “sulphur rain”. After pollination the female cone develops for about two years. In Scots pine the cone ripens in the autumn of the second year, and the winged seeds fall only in the spring of the third year. In some species, such as the stone pine, ripening takes three years.

## Pines growing in the Czech Republic

### Native species

**Scots pine (Pinus sylvestris)** is a tree usually 25–35 m tall, exceptionally over 40 m. It has pairs of blue-green, slightly twisted needles 3–7 cm long and cones 3–7 cm long. It is easy to recognise by the orange bark on the upper trunk. It grows from lowlands to mountains and does best on poor sandy soils, rocks and peat bogs. It is the most widespread pine in the country.

**Mountain pine (Pinus mugo)** is a multi-stemmed shrub with sprawling branches, usually 1–3 m tall. Its needles are in pairs, dark green and 3–8 cm long. It is native to the highest parts of the Krkonoše (Giant Mountains) and Šumava (Bohemian Forest), where it forms continuous thickets above the treeline. Elsewhere, for example in the Hrubý Jeseník mountains, it was planted in the past and is now crowding out valuable treeless alpine habitats.

**Bog pine (Pinus uliginosa, syn. P. rotundata)** grows as a single-stemmed tree up to about 20 m tall, or as a shrub. It is tied to peat bogs, for example in the Třeboň region, Šumava, the Ore Mountains (Krušné hory) and the Slavkov Forest. Taxonomically it belongs to the group of mountain pine and mountain pine's western relative P. uncinata. Botanists still debate its classification, and sources list it either as a separate species or as a subspecies. Where mountain pine and bog pine meet, hybrids known as *Pinus ×pseudopumilio* arise.

### Non-native pines in forests, parks and gardens

**Swiss stone pine (Pinus cembra)** is not native to the Czech Republic. It grows naturally in the Alps and Carpathians, and here it is found only where planted, for example in the mountains and in parks. It has five needles per bundle and cones that do not open; birds and rodents extract the seeds. Older literature sometimes wrongly equated it with the **Siberian dwarf pine (Pinus pumila)**, which is in fact a separate shrubby species from the Russian Far East and Siberia.

- **Austrian pine (Pinus nigra)** has stiff, dark needles 8–16 cm long. It was widely planted on limestone slopes and spoil heaps in the past. In the Bohemian Karst it is spreading in places into valuable steppe habitats.
- **Eastern white pine (Pinus strobus)** comes from North America. It has soft five-needled bundles and long, narrow cones. In Bohemian Switzerland it has become invasive, and the national park administration is actively removing it.
- Other garden species include Bosnian pine (P. heldreichii), Macedonian pine (P. peuce), jack pine (P. banksiana), ponderosa pine (P. ponderosa), Japanese white pine (P. parviflora) and Bhutan pine (P. wallichiana).

## Habitat and ecology

Pines are typical **pioneer trees**. They need plenty of light and tolerate drought, frost and poor, acidic or, conversely, calcareous soils. That is why they are often the first to colonise sands, rocky ridges, peat bogs and abandoned quarries. In such places they are often accompanied by [birch](https://www.stromyvcr.cz/briza/). On more fertile soils, however, they are gradually overtopped and shaded out by beech, spruce or fir.

Natural **pine forests** in the Czech Republic occur on the sandstones of the Kokořín area and Bohemian Paradise (Český ráj), around Doksy, in the Třeboň region and on the sands of South Moravia near Hodonín. A large share of pine forests, however, was planted by people. Pine has a deep taproot and is therefore more resistant to windthrow than spruce.

Even pine does not cope with drought unscathed. After the dry years following 2015, pine stands have been dying en masse, especially in South Moravia and Central Bohemia. Weakened trees are attacked by the **six-toothed pine bark beetle**, fungal diseases and **pine mistletoe** (*Viscum album* subsp. *austriacum*). Cones and seeds are an important food for crossbills, squirrels and woodpeckers. Pines also live in symbiosis with mycorrhizal fungi, such as slippery jacks and the pine bolete.

## Timber and uses

Pine is a softwood, but it is harder, heavier and more resinous than spruce. Its density is around 500–550 kg/m³. It has a reddish to brownish heartwood and pale sapwood, and it is easy to work. Thanks to its resin it is more durable, and once treated it lasts a long time even outdoors.

- **Construction** uses include roof trusses, beams, windows, floors, decking and posts.
- The wood is also used in **furniture making and joinery**, as solid pine is popular for its grain.
- It is processed into **pulp and wood-based panels**.
- **Resin** was formerly used to produce turpentine, rosin and tar.
- Needles and young shoots are used in **herbal preparations**, such as essential oils for inhalation and baths or syrup made from pine “candles”.
- **Edible seeds**, known as pine nuts, come mainly from stone pine (P. pinea), Siberian pine (P. sibirica) and Korean pine (P. koraiensis).

## Growing pines in the garden

Pines are among the least demanding conifers, but when choosing a site you need to allow for their eventual size. Scots or Austrian pine will grow into a large tree, so mountain pine and dwarf cultivars are better suited to smaller gardens.

### Site and soil

- Choose **full sun**; in shade, pines thin out and lose their lower branches.
- The soil should be **free-draining**, even sandy or stony. Pines particularly dislike permanent waterlogging and heavy clay. The exception is bog pine, which is adapted to peat bogs.
- Scots pine tolerates acidic soils, while Austrian pine and mountain pine also cope with calcareous soils.

### Planting and care

The best time to plant is spring or from late August to October, ideally using container-grown plants. Pines with taproots do not take well to transplanting at larger sizes. Water during dry spells for the first two years after planting; older pines usually need no irrigation. Fertilise only minimally. To keep mountain pines or bonsai compact, shorten the young shoots, known as “candles”, by about half to two thirds in late May to early June. Pines do not produce new shoots from old wood.

Popular garden cultivars include mountain pine *'Mops'*, *'Gnom'* and *'Pumilio'*, Scots pine *'Watereri'* and dwarf forms of eastern white pine such as *'Radiata'*.

### Pests and diseases

- **Pine needle cast** causes browning and needle drop in young plants. An airy site and removal of infected fallen needles help.
- **Red band needle blight** (Dothistroma) and **shoot dieback** (Diplodia) mainly affect Austrian pine.
- **White pine blister rust** attacks five-needled pines and needs currants as an alternate host, so do not plant eastern white pine near blackcurrants.
- Pests include the **nun moth**, **sawflies**, **pine weevils** and **bark beetles**, which mainly attack drought-stressed trees.

## Curiosities and cultural significance

- The Old Czech and Slavic name for pine is **sosna**. It survives in many place names and in the Czech name for the pine weevil, sosnokaz.
- The Great Basin bristlecone pine in California's White Mountains is among the oldest living organisms on Earth, estimated at over 4,800 years old.
- The genus is found mainly in the Northern Hemisphere. Only one species, Sumatran pine (P. merkusii), naturally crosses the equator, on Sumatra.
- In East Asia the pine symbolises longevity and endurance, and it is among the most prized trees in Japanese gardens and bonsai.
- Pine pollen grains have two air sacs, which allow the wind to carry them tens of kilometres; preserved in peat bog sediments, they help scientists reconstruct ancient forests.

## Summary

The pine is a hardy, light-demanding conifer recognisable by its needles in bundles. Scots pine, mountain pine and bog pine are native to the Czech Republic. Swiss stone pine, Austrian pine and eastern white pine were planted, and some are spreading undesirably. Pines colonise sands, rocks, peat bogs and mountain ridges and provide high-quality, resinous timber. In the garden they are undemanding, provided they get enough sun and free-draining soil.

## FAQ

**How many pine species grow in the Czech Republic?**

Three are native: Scots pine, mountain pine and bog pine, plus their hybrids. A number of non-native species have been planted, most commonly Austrian pine, eastern white pine and Swiss stone pine.

**How can I tell a pine from a spruce?**

Pines have needles in bundles of two to five, wrapped in a sheath at the base. Spruce has short, four-sided needles borne singly. Pine cones are also shorter, with hard woody scales.

**Is Swiss stone pine native to the Czech Republic?**

No. Swiss stone pine grows naturally in the Alps and Carpathians; in Czechia it is found only where planted in mountains, parks and gardens. It is not the same species as the Siberian dwarf pine (Pinus pumila) from the Russian Far East.

**How long do pine cones take to ripen?**

In most pines, including Scots pine, the cone ripens about two years after pollination and the seeds are released in the spring of the third year. Some species, such as the stone pine, need three years.

**Is pine a softwood?**

Yes, it is a coniferous softwood, but it is harder, heavier and, thanks to its resin, more durable than spruce. It is used for roof trusses, floors, windows, furniture and decking.

**When and how should I prune mountain pine in the garden?**

In late May to early June, shorten the young shoots, known as candles, by about half to two thirds before the needles unfold. Do not cut into old wood, as pines will not produce new shoots from it.
