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

Arolla Pine requires abundant, bright and direct light. Placing it less than one foot from a window is the best way to make sure the plant receives enough light to survive and thrive. Depending on your region, however, the current weather can affect the placement of the plant in your home. For example, in some areas the sun may be too direct and intense, so it's best to place it farther away from the window. You may also need to adjust your placement according to the season as the sunlight can change intensity over the course of the year. If you live in a region with significant temperature fluctuations, such as a desert, you may need to place the plant a bit farther away from the window to avoid extreme heat or cold. With some care and attention, your Arolla Pine will be sure to bring you many years of beauty and enjoyment.
