Planting common myrtle
Myrtle is a plant native to the Mediterranean area. It finds cold weather unbearable, especially over long periods of time.
It’s preferable to plant common myrtle in fall to favor root development and renewed growth in spring.
It is also possible to plant common myrtle in spring provided you diligently water it all summer long for the first year.
- Common myrtle prefers locations with high exposure to sunlight.
- It likes rich, well-drained soil: that is where it flowers best.
- Adding soil conditioner when planting enhances settling in and root development.
- Water well during the first 2 years after planting.
Common myrtle in pots and containers
Also try planting common myrtle in pots outside: just avoid both below-freezing temperatures and hot weather.
Potted common myrtle is ideal wherever winters are harsh. Pots are easier to move around and bring indoors during winter (greenhouse or unheated lean-in).
Propagating and preparing common myrtle cuttings
Myrtle bears incredible amounts of seeds. Each season, new waves of sprouts emerge throughout the garden. Usually, birds spread seeds around when eating the berries.
- Keep a few seeds from ripe berries. Dry them and store in a paper envelope in a cool, dry spot.
- Sow in spring.
New plants may come out very different from the mother plant because of cross-pollination.
Cuttings, the way to get an exact same myrtle plant
A myrtle plant is quite easily multiplied through cuttings from semi-hardened sprigs. It’s the simplest propagation method.
Prepare your myrtle cuttings in spring or at the end of summer, on soft-wood growth, that is, wood that is not hard yet, nor has grown brown bark, but is in the process of hardening.
- Collect stems about 6-inches (15 cm) long.
- Remove lower leaves, leaving only the topmost one or two pairs.
- Plant the cuttings in special cutting soil mix or a blend of peat and river sand.
- Keep the substrate a little moist.
Protect your cuttings before winter
- Protect your common myrtle cuttings with a tunnel greenhouse or any other solution that maintains a temperature of at least 40°F (5°C).
Transplant in spring
- When the last frosts are past, towards mid-May, transplant in nursery pots one size larger.
- Transfer your myrtle cuttings to the ground in the following fall.

Pruning and caring for common myrtle
Although not pruning at all will suite the shrub fine since it rarely exceeds 16 feet (5 m) tall, you can balance or reduce the breadth of your common myrtle at the beginning of spring. Prune delicately.
To keep a compact appearance, trim the year’s new shoots back to half their length after the blooming.
Increase blooming by often adding liquid organic fertilizer. This is especially true for indoor plants since potted soil quickly loses nutrients.
Pests and diseases on common myrtle
Myrtus communis isn’t a favorite of many animals, so you will rarely have problems. For example, larger animals such as deer don’t like it. Insects (aphids, spider mite, scale…), if they appear, quickly move on to other hosts.
Myrtle resists diseases well, including honey fungus.
