Pinus cembra aka Arolla Pine

Taxonomy

Pinus cembra, also known as Swiss pine, Swiss stone pine, Austrian stone pine, or Arolla pine, is a slow-growing, columnar evergreen with upward-turning branches. It has a narrow, pyramidal habit, making it ideal for small landscape settings. This species of pine tree is part of the subgenus Strobus and is native to the mountainous regions of Central Europe. Swiss Pine is exceptionally tolerant of winter winds and cold and prefers climates with cool summers. The evergreen foliage provides year-round color, and pine cones add seasonal interest. Swiss Pine is a super rare houseplant that is easy to grow and needs regular watering to thrive. It does best in long-lasting, direct light and should be placed less than 1 foot from a window. The plant prefers soil that is well-draining and should be repotted each time it doubles in size. As a member of the Pinus genus, Swiss Pine is native to Central Europe. Fertilizers are usually unnecessary for this plant when repotting.

How to care for Arolla Pine

Difficulty

Arolla Pine requires a bit more attention and knowledge to thrive, making it a suitable plant for those with some gardening experience.

Water

Arolla Pine should be watered regularly, allowing the soil to dry out between waterings.

Soil

Arolla Pine loves a well-draining soil. Perlite and vermiculite help with drainage, while coco coir adds organic matter, so a good potting soil mix will have all three. You can improve store-bought soil by adding some perlite to it.

Lighting

To ensure optimal growth, the Arolla Pine prefers bright diffused light for 6-8 hours each day. Insufficient light can result in slow growth and leaf drop, so it's important to find a well-lit location for this plant. Place it near a window, within a distance of 1 meter (3 feet), to enhance its potential for thriving.
