The rosemary ( Rosmarinus ) is one of aromatic herbs most reputable. Its leaves are like long, bluish-green needles that perfume Mediterranean-inspired recipes. You can also make fragrant flower beds.

How to Plant Rosemary 2021 Care,Harvest By Backyard Garden Usa


Seeding can be done quite easily at home, from April. It should be noted, however, that small rosemary plants will take about 1 year before they can be transplanted into the garden.

If you're patient enough, here's how to grow rosemary from seeds . First, fill seedling boxes with a mixture of potting soil and fine sand. Then, mix the tiny seeds with fine sand.

Then, sow fine pinches of this mixture in the boxes, spacing them 4-5 cm. Water lightly with a sprayer. The earth must remain barely wet.

Finally, place the boxes in full light, without covering them.

As soon as the small plants can be handled (when they reach about 2-3 cm), the weakest ones can be removed to keep only one every 5 cm, which prevents rotting.

At the end of summer, they can be transferred to individual pots, then cared for until the following spring for planting in the garden.

Growing rosemary in pots

Rosemary can easily be kept in pots or a planter. It grows well on the balcony or on the edge of a window, facing south. This plant will live for several years if taken care of, provided you repot it occasionally in a larger pot as its roots expand.

Growing rosemary in the garden

Rosemary plants can be transplanted directly to the garden towards the end of May. They should be spaced 40-50 cm apart. If possible, bury small peat pots directly, because the plant is sometimes difficult to transplant when the roots are not yet very mature.

To transplant rosemary, make a hole the same size as the pot or clod of earth. Add gravel to the bottom of the hole, if the soil is too clayey, and place your plant in it.

Then cover it with soil and water the plant thoroughly.

In what type of soil?

Rosemary likes very well drained soils, even stony or limestone. It may be necessary to mix soil with sand. It prefers arid and very dry soils to fertile and moist soils.

In pots, it is recommended to cover the bottom with a layer of gravel or fine beads to avoid moisture stagnation.

What exhibition?

Rosemary grows in full sun or partial shade, sheltered from strong winds.

The interview

Rosemary does not require a lot of care. It is simply necessary to:

  • Regularly remove weeds around the base.
  • Add compost once a year when the soil is very poor.
  • Prune branches after flowering. You can thin the plant in half at this time.
  • Water sparingly, if at all, if it rains regularly. Once the plant is well adapted, in the ground (after 1 or 2 years), you can even stop watering it at all.
  • Rosemary tolerates the cold well. It is enough to protect it for the winter by placing it under a polystyrene bell so that it comes back to life each spring.
  • It is also possible to let it bloom outside in a large pot, then bring it in in late fall.

For indoor cultivation, watch these points:

  • It is necessary to wait until the soil is quite dry between each watering.
  • Avoid placing a saucer to keep water under the pot: constant humidity is harmful for the rosemary plant.

Pests and diseases to watch out for

Rosemary is particularly resistant to external attacks. It is occasionally the prey of leafhoppers, leaf beetles (a small black insect) or aphids .

When and how to harvest rosemary?

Rosemary can be harvested all year round (hence the advantage of growing it in pots). You can simply tear off the top of the stems or a few leaves at a time. During the pruning period, complete stems are cut off at the base, which can then be dried for later use.

Good and bad associations with the vegetable garden

In the vegetable garden, rosemary grows very well with carrots, cabbage, fennels, peas, potatoes and tomatoes. It can also be planted with parsley and thyme , in a planter of aromatic herbs.
