How Much Space to Leave Between Each Princess Pine Plant

Princess Pine (Lycopodium obscurum), also known as ground cedar or tree clubmoss, is a popular choice for landscaping due to its attractive appearance and low maintenance requirements. It is a slow-growing perennial that spreads through rhizomes and can be used as a groundcover or in rock gardens. When planting Princess Pine, it is important to consider the spacing between each plant to ensure optimal growth and visual appeal. In this article, we will discuss how much space to leave between each Princess Pine plant.

Factors to Consider

Before determining the ideal spacing for Princess Pine plants, there are a few factors that need to be considered:

1. Growth Habit

Princess Pine plants spread through underground rhizomes and can slowly form dense colonies over time. Their growth habit needs to be taken into account when deciding on the spacing between plants.

2. Plant Size

The size of mature Princess Pine plants should also be considered. They typically reach a height of 6-12 inches, with a spread of 12-24 inches. This information helps determine how much space each plant needs to grow without overcrowding.

3. Purpose of Planting

The purpose for which you are planting the Princess Pines also plays a role in determining the spacing. If you want them to form a dense groundcover, closer spacing may be preferred. However, if you want to showcase individual plants or create an open and airy look, wider spacing would be more appropriate.

4. Environmental Conditions

Environmental factors such as sunlight, soil fertility, and moisture availability can affect the growth of Princess Pines. Proper spacing allows each plant to receive adequate resources for healthy development.

Ideal Spacing Recommendations

Based on the factors mentioned above, here are some general recommendations for spacing between Princess Pine plants:

1. Groundcover Planting

If you are planting Princess Pine as a groundcover, closer spacing is typically preferred to achieve a dense and uniform appearance. A spacing of 6-8 inches between plants is often recommended. This allows the plants to grow and establish a cohesive mat while minimizing bare patches.

2. Individual Planting

For showcasing individual plants or creating an open and airy look, wider spacing is recommended. A spacing of 12-24 inches between plants allows each plant to have its own space and stand out. This arrangement also facilitates air circulation and reduces the risk of disease and pests.

3. Mixed Planting

Princess Pine can be planted alongside other low-growing plants or in rock gardens for added visual interest. In such mixed plantings, it is important to consider the growth habits and spacing requirements of the accompanying plants as well. Generally, a spacing of 12-18 inches between Princess Pines and other plants is suitable to allow for proper growth and prevent overcrowding.

Tips for Planting

Here are some additional tips to ensure successful planting and growth of Princess Pine:

Prepare the Soil: Princess Pines prefer well-draining soil that is slightly acidic. Amend the soil with organic matter like compost or peat moss before planting to improve drainage and fertility.
Watering: Provide regular watering during the establishment phase to help the plants develop a strong root system. Once established, Princess Pines are relatively drought-tolerant but still benefit from occasional watering during dry periods.
Mulching: Apply a layer of organic mulch around the plants to help retain moisture, suppress weeds, and regulate soil temperature.
Maintenance: Princess Pines require minimal maintenance. Remove any dead or damaged foliage as needed and avoid over-fertilizing, as excessive nutrients can promote excessive growth.
Propagation: If you want to expand your Princess Pine collection, you can propagate them by dividing the rhizomes or planting spores. This should be done in early spring or fall for best results.

Conclusion

Determining the appropriate spacing between Princess Pine plants is crucial for their optimal growth and aesthetic appeal. Consider factors such as growth habit, plant size, purpose of planting, and environmental conditions when deciding on the spacing. Whether you want a dense groundcover or an open and airy arrangement, proper spacing ensures healthy development and an attractive landscape. Follow the recommended spacing guidelines mentioned in this article and enjoy the beauty of Princess Pine in your garden or landscape.
