Question: yucca

Good morning.
I write from Verona where I and my beautiful yucca plant live.
This plant has always enjoyed splendid health, in the apartment during the winter and on the balcony in the summer, not exposed to direct sunlight but covered by an awning (I state that in any case the sun beats on this balcony only in the morning until about 12.00)
Last summer, in fact, the plant was so good that it practically had an explosion of growth so much that it is now difficult to find a place in my, not very small, but small apartment.
However, everything was fine until three weeks ago when I noticed that some leaves are yellowed and then completely dry.
The situation is now getting significantly worse ... I would like advice.
Do I have to repot it because now the vase is a little tight since it is so grown?
I have to water more ????
In winter I always watered about once a week, even adding liquid fertilizer for indoor plants, in the summer every day.
Please help me I am very fond of this plant and I would very much like to lose it.
I look forward to your valuable advice.

Yucca: Answer: yucca

Dear Elena,
Thank you for contacting us about your Yucca problem through the "" Expert's column.
The Yucca also known as "Tronchetto della felititita" is a plant characterized by the presence of shoots and slender leaves of intense green color, which grow directly on a trunk similar to a trunk from which the name attributed to them.
They are evergreen plants comprising over 40 varieties, originating from Central America that require, in order to grow appropriately, the environmental conditions of the country of origin but which are well suited to growing in pots in domestic environments.
Yucca requires modest watering and frequent spraying on the leaves, especially with high temperatures and good brightness.
The symptomatology that has described (sudden yellowing of the leaves that become dry) can be linked to various factors: light, water and nourishment.
If the watering had been excessive it would have manifested itself with the decay of the leaves and the stem would have become soft. Repotting should be done every 1-2 years, if it has not been done, perhaps the roots are too developed.
Very probably the course is caused by a high dryness of the environment and by a reduced brightness of the room (the leaves that yellow first are the oldest).
For the prompt recovery of the plant we advise you to verify if the root system is indeed too developed, in this case it is necessary to intervene with an appropriate repotting.
Move the plant to a more illuminated position and fertilize it regularly.
