Nicknamed the golden tree, the mimosa blooms in winter and brings a real ray of sunshine both outdoors and indoors. Its yellow flowers are delicately revealed from January to March and fill the air with their captivating fragrance. It is not very hardy, which is why it is mainly observed in the Mediterranean region . However, it grows very well in pots for other regions! Here are 5 tips for growing mimosa in pots.
- 1) The choice of pot
- 2) The choice of substrate
- 3) Choose the location of the mimosa well
- 4) Maintenance in pots and indoors
- 5) Wintering
1) The choice of pot
The secret to a flourishing mimosa indoors is first of all the choice of pot. If you want to see your mimosa bloom abundantly, know that it will prefer a slightly narrow pot. However, the pot should be deep, as the mimosa’s root system is quite large.
The pot should therefore be twice as large as the root ball of the plant. This represents a pot of about 40 to 50 cm in diameter for a plant 3 m high.
If you can, choose an unglazed terracotta pot. The pot must obviously be pierced in the bottom to avoid stagnant water and rotting of the roots.
2) The choice of substrate
The mimosa appreciates fertile, light and low acid substrates. However, the most important thing is that the substrate is well draining, because the main enemy of the mimosa is excess water.
The substrate should be made up of a mixture of heather soil, potting soil and a little river sand. Planting takes place in the spring between March and June. Don’t forget to add clay pebbles or gravel to the bottom of the pot to improve drainage.
3) Choose the location of the mimosa well
The ideal exposure for the mimosa is full sun. It likes heat and needs good light. In pots, it must be exposed to sunlight for at least 4 hours a day. He also fears drafts.
4) Maintenance in pots and indoors
On the maintenance side, the main thing is to control the watering. The mimosa does not like hard water. Prefer rainwater to water your plant regularly, leaving the substrate to dry on the surface between two waterings. It must remain cool, but beware of excess water. In winter, water once a week.
During the summer season, bring special fertilizer for flowering plants every 15 days. Finally, after flowering, prune the plant by shortening the branches by half. Repot every two years.
The mimosa does not really support heavy frosts. Wintering is therefore a very important step to keep it as long as possible. In addition, growing in pots allows the mimosa to be indoors in winter. The room should be cool and bright. A winter garden would therefore be ideal. You can put the pot back in the garden in the spring, after all the frosts have passed.
