When to plant: Plant the Effusa Common Juniper at any time during the growing season when there is no danger of frost.
Dig a planting hole twice the size of the root ball and as deep as the soil in the container. Place the plant in the planting hole, then backfill will soil. Mulch and water well. The Effusa Common Juniper is drought and seashore tolerant. It is also slope tolerant - plant it on a slope to help keep washout to a minimum.
If the Effusa Common Juniper is balled and burlaped, and the burlap is organic, set the entire plant and burlap bag into the hole. Unstaple or untie the top of the burlap and fold it down along the sides to be sure it gets covered with soil. If the burlap is synthetic, remove it, as synthetic burlap will not decompose.
Water the Effusa Common Juniper with an inch of water when the top two inches of soil dry out. Always water deeply, encouraging the roots to grow deep, especially if planted on a slope or in a windy area.
Do a soil test prior to fertilizing. The Effusa Common Juniper should be fertilized once a year. If the soil test reveals a missing or low nutrient, use a fertilizer higher in the missing or low nutrient, otherwise use an all around flowering shrub and tree fertilizer.
The Effusa Common Juniper is a low maintenance evergreen that produces green and silver foliage. The undersides of the needles are green and the top of the needles have a silvery sheen to them.
The Effusa Common Juniper is not susceptible to disease.
Leaf Miners: A leaf miner is the larvae of different bugs - moths, flies and beetles. The leaf miner creates a tunnel between the upper and lower surface of the leaves. They are attracted to vegetables and ornamental plants. To control leaf miners, keep the area well weeded, introduce parasitic wasps and remove and discard infected leaves. Some insecticides may kill leaf miners.
Caterpillars: Caterpillars are heavy feeders and can be quite destructive. They are the immature form of butterflies and moths. Help control caterpillar infestations by removing all weeds around the area and introducing parasitic wasps to the garden. If you are still having problems, certain insecticidal soaps and oils will kill the caterpillars.
Prune the Effusa Common Juniper in the spring and throughout the growing season for dead and decaying wood and plant matter. Pinch the stem tips to encourage a bushier plant. Always remove fallen plant debris from under and around the plant.
The easiest way to propagate the Effusa Common Juniper is via stem cuttings. Cut a stem tip, leaving a few needles at the top of the cutting. Dip the stem tip in rooting powder and plant. This will work with an herbaceous cutting or a woody cutting, but you will have better luck with an herbaceous cutting.
