Question: Mimosa flowers


Why do the flowers of my mimosa just buried by yellow turn brown?

Answer: Mimosa flowers


Dear Rosario,
the flowers of the mimosa become brown when they naturally wither, or when they are in poor crop conditions, such as severe drought or excessive humidity.
In general, plants do not suffer great stress when they are moved from a small vase to the ground, but it is likely that your plant has undergone transplantation as a dramatic event, and therefore its flowers are simply withered with speed, as the plant was subjected to a shock.
If this is a problem of this kind, I think you shouldn't worry, as the plant has only implemented a defense action against adversity: stress has not allowed it to be able to develop at its best, and therefore has given up on bring to the fore the expendable part, or flowers. If the rest of the plant is fine, don't worry, next year you will enjoy a longer and more persistent flowering.
If, on the other hand, the plant is kept in conditions unfavorable to its development, in addition to the withered flowers, you will also notice other symptoms, such as poor spring vegetation, leaves that dry up or apexes of the dark branches.
In these cases it is certainly a question of problems in the position of the plant, or in the watering.
The mimosas (acacia dealbata) are native to Australia, and were introduced into cultivation in Europe several centuries ago; nowadays you can find several specimens in Italian gardens, and even in the wild, especially along the coasts and in Puglia, Calabria and Sicily, where small groves can be seen, with spectacular blooms towards the end of winter.
These are large shrubs, or small saplings, quite delicate, which fear intense cold; they settle in full sun, with at least a few hours of direct sunlight every day; if you live in an area with very cold winters place your mimosa in an area sheltered from the wind, and where you can easily cover it with non-woven fabric in case of intense and persistent frosts.
Watering is the key to having a healthy and luxuriant plant: in fact mimosas love a fresh and slightly humid soil; when it dries a lot, you will have to water yourself, especially in periods with a mild or warm climate.
They prefer a slightly acid pH soil, and from April to September it is good to mix fertilizer for flowering plants with the water used for watering. In general, after flowering, a light pruning is carried out, as the mimosas tend to develop a very disordered crown growing.
