Why isn't my yesterday-today-tomorrow (Brunfelsia pauciflora) blooming?

When seeing other people's yesterday-today-tomorrow plants full of flowers and lush leaves, some flower lovers find that their own yesterday-today-tomorrow isn't blooming, and search everywhere for the reason, trying all kinds of fertilizing, lighting and watering, but still can't find the cause. If you want your yesterday-today-tomorrow to bloom on time, the correct care method is the most important thing.

First, flower lovers need to understand when the yesterday-today-tomorrow blooms. The yesterday-today-tomorrow can bloom twice a year, and some bloom multiple times, but the main flowering period is in spring. Although it still blooms afterward, the amount of bloom is much smaller, perhaps just a few flowers. So flower lovers shouldn't demand a full amount of flowers from the yesterday-today-tomorrow at any time; the plant's normal flowering cycle should still be respected.

After the flowering period, the yesterday-today-tomorrow should be pruned appropriately, otherwise it will affect later blooming, so prune in time. After each bloom fades, promptly cut off the spent flowers, and cut some long branches back by 1/3 to 1/2 to encourage more branching, which helps produce more flowers the following month; after the last bloom fades in late autumn, do a heavy pruning, that is, keep 2 to 3 buds on each branch and cut off the rest, and remove thin and weak branches, inward-growing branches, and diseased or pest-infested branches, to encourage branching the following spring.

Reasonable fertilizing: although fertilizing is needed, some flower lovers completely ignore the actual situation, applying whatever fertilizer they have regardless of the amount, causing the yesterday-today-tomorrow to only grow leaves, or even causing fertilizer burn. Fertilizing should follow the principle of light and frequent applications, and stop fertilizing in winter.

Light and water control: it's true that the yesterday-today-tomorrow needs plenty of water and fertilizer, but in spring you should control water appropriately, as this helps flowering. If water is plentiful, the branches and leaves will flourish, but the flowers will be pitifully few or even absent. As for light, the yesterday-today-tomorrow only blooms profusely under sufficient sunlight (flower lovers should note that light must be moderate, and shade is needed under blazing sun), so there's no need to say more here.
Sometimes, the problems of flower lovers require them to slowly investigate on their own based on others' experience, and understand little by little, because in different environments, the situation of each pot of flowers is not the same. So flower lovers shouldn't blindly put an article into practice; they must combine the article with the actual situation, and then think, so they can improve.

Reasons why the yesterday-today-tomorrow doesn't bloom

Improper watering

If watered too much, it easily causes leaves to grow excessively, and the branches and leaves absorb the nutrients, thus affecting flowering. So watering should follow the principle of watering when dry and stopping when wet. To keep the air humid, you can spray clean water on the leaves.

Improper fertilizing

Choosing a fertilizer with too much nitrogen causes vigorous growth of branches and leaves, and with a lack of phosphorus and potassium fertilizer, flower buds cannot differentiate. Because leaf growth consumes a large amount of nutrients, the yesterday-today-tomorrow cannot bloom.

Improper pruning

When the flower buds of the yesterday-today-tomorrow are differentiating, if it is not pruned in time, the plant's light penetration is poor, so the buds drop early, affecting flowering.
