Juniperus communis 'Compressa'

The Common Juniper (Juniperus communis 'Compressa') is a coniferous, evergreen tree that can reach heights of up to 6m (20 feet). It has bright green, prickly needles, rusty brown bark and blue-black berries. The berries are edible, used in sauces and liqueurs, as well as in flavourings for meats and vegetables. This species is well adapted to marginal lands, so it is often used for land reclamation and soil erosion control. It grows well in full sun and prefers neutral to slightly acidic soils. Regular pruning will help it maintain a neat, compact shape. Common Juniper is even able to survive in harsh residential areas, making it an ideal ornamental plant.

watering

Common Juniper (Juniperus communis 'Compressa') should be watered about once to twice a week, depending on temperature and other environmental factors. Generally, it should receive 1 to 2 inches of water each week. If the weather is particularly hot and dry, increase the frequency and amount of water it receives slightly, but be sure not to overwater. During the winter months, reduce the amount of water the plant is receiving, as it is dormant and needs less water.

sunlight

Common Juniper thrives in full sun, meaning at least 6 hours of direct sunlight per day. The optimal sunlight exposure for this species is between 8-10 hours of direct sunlight per day. Juniper likes to get as much light as possible, but also needs some respite from direct heat during periods of extreme heat. It is important to find an appropriate location with consistent and ample sunlight for Common Juniper, as inadequate sun exposure can lead to poor growth, or even death of the plant.

pruning

Common juniper (Juniperus communis 'Compressa') should be pruned between late spring and early summer for the best results. The amount of pruning depends on how large the plant is, but it should generally be done lightly to avoid damaging the plant. New branches can be cut back to 1-2 nodes, or 1-2 inches. This should generate enough new growth to create a denser, more compact shrub. If necessary, older growth can be removed to thin out overgrown areas or to create a hedge. It is also beneficial to cut lower branches off to allow for better air circulation. Dead or broken branches should be removed as soon as they are detected.
