Origins and characteristics of mimosa

The mimosa, as we know it today, is part of the Mimosaceae family, but belongs to the genus of acacias and not to that of mimosas. The two flagship varieties of this genus are winter mimosa, also called "flower shop mimosa", and the four seasons mimosa. These species are native to Australia and there are more than 1,000 different for the pleasure of amateurs.

The pretty color of its flowers and the smell it gives make the mimosa one of the favorite trees of budding gardeners. The mimosa is a fast growing tree: it gains up to 60 centimeters per year. It has a lifespan of around 50 years, which is relatively short for a tree.

Mimosas are invasive plants.

Mimosa plantation

The mimosa is a tree that should be planted in the spring. It is a tree that likes heat, the sun and well-drained soils. Generally, he does not like clay or limestone soils, except the 4 seasons mimosa which supports this type of soil well.

Flowering takes place at different times depending on the variety chosen. The mimosa of the four seasons, meanwhile, flowers throughout the year and more particularly during the summer.

It is a tree which tolerates negative temperatures but which needs to be well exposed to the sun. Some varieties need to be protected from prevailing winds by being planted against a wall.

The mimosa can be planted in the ground or in pots. However, never plant two mimosas side by side; leave about 3 meters between plantings.

When planting in the ground, make sure to leave the graft above the ground. Use a tutor because the wood of mimosa is easily brittle, especially on young plants. After planting, do not add fertilizer and do not water the young plant.

For a pot planting, be sure to choose a deep pot whose size is quite substantial. In fact, the roots of the mimosa will become important as it grows. In order to properly drain the soil, remember to put 3 to 5cm of clay balls in the bottom of the pot.

For feet planted in the ground, as soon as the temperature reaches -5 ° C, you must quickly cover the antlers with a winter veil (two layers if possible).

It is advisable to proceed with the pruning of themimosa tree every year, especially if it is in a fairly windy area. The pruning of the twigs is done after flowering and stops the unnecessary appearance of new pods. It is also important to ventilate the antlers by freeing them from unnecessary branches.
