Freesias and calla lilies

Question: why don't my plants bloom?

I have freesias but for some years (even with lush foliage) they give me only 3 or 4 flowers. The same applies to the calle. Answer me thanks

Freesias and calla lilies: Answer: cultivate bulbous plants

Dear Anna,
plants that produce bulbs, rhizomes, tubers, as everyone knows, use these modified organs to store nutrients; these substances, in the form of starches or other sugars, and mineral salts, are used the following year to produce the flowers, since the flowering, and the consequent fructification, are events that require great energy costs for the plants.
The reasons why a bulbous plant stops flowering, or from year to year the number of flowers decreases, are related precisely to the availability of these nutrients: if they are few or scarce, the flowers will be few or no.
How do you promote the storage of nutrients by a bulbous or rhizomatous plant?
Plants produce nutrients through chlorophyll photosynthesis, so it is essential to best cultivate the leaves of our bulbous plants, avoiding pruning them when the plant has just stopped flowering; the practice of pruning the foliage of bulbous plants deprives us, from year to year, of ever greater flowers, since we leave little time for the plant to practice photosynthesis, and therefore to produce nutrients and therefore to store sufficient resources for flowering. 'next year. The leaves must therefore be watered, fertilized and left to vegetate until they begin to dry up on their own.
Another reason why this does not happen can also be related to the soil in which the plants are grown, which can be excessively poor in mineral salts; or, especially if you keep your bulbs in pots, it may be that over the years the rhizomes of the calla lilies have widened excessively, or the freesias may have produced lateral cloves: in an excessively crowded terrain, competition is excessive, and the result is a total lack of blooms, since there would still be no room for the new bulbs produced by the seeds.
So if you cultivate your bulbs in pots, they may need repotting, to enlarge them, providing more space for each bulb, but also to provide fresh new soil.
Another reason related to poor flowering could be related to the climate: bulbous or rhizomatous plants often need a winter vegetative rest period to be able to flourish at best; at the same time, late frosts, when the plants are already sprouting, can ruin future buds and cause the absence of flowers.
In winter, bulbous plants and rhizomes should be left without water and fertilizer, so that they enter vegetative rest until spring; if grown at home, with an excessively hot climate, flowering is unlikely to occur the following year.
