Bougainvillea and caper

Question: bougainvillea and caper

the nia bouganvillea, despite being exposed in full sun, does not bloom. What should I do to flourish?
and, then, I can't get caper plants despite leaving the seeds in the old tuff walls and in the ground. where am I wrong?

Answer: bougainvillea and caper

Gentile Gina,
the bougainvillea are plants native to Brazil, which also develop well in the Mediterranean climate; if the plant is well developed and healthy, or if it produces new branches and has a beautiful vigorous foliage, then the problems for which it does not bloom are not to be sought in the cultivation method, in watering, in fertilizer or in exposure. Unfortunately these plants are a little delicate, and therefore normal care can none be sufficient to obtain a bougainvillea full of flowers. Generally the lack of flowering can be linked to pruning: if the plant is excessively pruned at the end of winter, most of the future buds are removed; in the same way, if the prunings (at least in the first years of life of the shrub) are not practiced, often the plant tends to develop very high, sacrificing the development of the lateral branches, those that will produce flowers. Therefore, towards the end of winter, it tries to shorten the longer branches, which tend to develop only upwards. If the plant is cultivated in pots, the problem can instead be linked to cultivation, or the bougainvillea may lack fertilizers, or the correct humidity. Another problem may be the wind, which dehydrates the plant and the soil, and tends to ruin the first buds, and therefore the plant refrains from producing others. As for the capers, the problem with their sowing is due to the low germination of the seeds, only a small percentage of caper seeds can sprout, and therefore it is usually preferred to propagate them by cuttings; or many seeds are sown, but in boxes filled with peat and sand in equal parts, so as to guarantee the correct cultivation conditions for future plants. They are typically sown in winter, in November or December, in order to use fresh seeds; if, on the other hand, you want to sow the now dry seeds in spring, before placing them, immerse them in water for at least one night. Avoid burying them very deep, you can also simply place them on the ground, and then press lightly with a finger, so that they adhere perfectly. The soil with the seeds should be placed in full sun, and it should be watered quite often, to favor seed germination. Once the seedlings have sprouted, you can thin out the waterings. In some areas of Italy, traditionally capers are sown directly in the dry stone walls that will receive them, but first the seeds are placed in a ripe fig, which is placed in the crack of the drywall. I honestly don't know how this is a legend, because I have never tried such a method; but if you have a fig plant, and lots of caper seeds, maybe try a pair; at the most, after a few months the figs will decompose and nothing will remain of your experiment.
