Suffering Camellias: Answer: cultivating camellias
camellias are also large, fairly slow growing shrubs, originating in Asia; in particular, the most cultivated camellias in Europe are hybrids of the Japanese species. They can survive even in pots, even for many years, but only if the cultivation needs are followed in the best way. Camellias are acidophilic plants, that is, they love acid soils, and cannot withstand high concentrations of calcium in the soil. If we cultivate them in pots, and water them with tap water, over the years the soil contained in the pots will tend to accumulate the limestone of the water, and therefore even the most acid peat, will progressively tend to have an ever-increasing ph basic. Acidophilous plants when they live in calcareous soils tend not to be able to absorb iron, which is necessary for life, from the soil and above all to perform photosynthesis in the best way; the result of many months in a soil rich in limestone, for an acidophilous plant, consists of yellowed, dull, sad foliage. Since your camellias are in pots, the best method to guarantee them a constantly acid soil is to repot them every 2-3 years, replacing all the earth in the pots, with soil specific for acidophilic plants. In this way, even if your plants, in addition to the rain water, will also receive calcareous water, the soil will not be able to accumulate so much limestone as to become harmful to the plants. The other problems of your camellias, such as dark spots and crumpled leaves, may have been caused by various problems. The first one that is usually thought of is water: camellias love a moist and fresh soil, and regular watering; this does not necessarily mean that the soil in which the roots sink must always remain soaked with water or with stagnant water; rather it is important that, from March to September, it never happens that the soil remains dry for a few days in a row, and therefore you will have to water regularly, especially in the state and when it does not rain. But if when you are watering, you notice that the soil is still damp, it postpones watering for at least a day. And even in the winter months, avoid leaving the plants in complete dry conditions, and at least once every 8-12 days, check the state of the soil, and if it is very dry, lightly water it. Another problem that often affects potted plants (all) is related to fertilizers: over the years the soil tends to lose most of the mineral salts, which are absorbed by the plant's roots; to restore the right level of mineral salts, we must necessarily intervene. If the pots are very large, it is sufficient to spread about a couple of spoonfuls of slow-release granular fertilizer on the surface of the pot, and bury it lightly with a small hoe; it will take about 4 months to melt, and therefore, if you spread it at the end of winter, it will continue to fertilize the plant until the summer. If, on the other hand, you have perseverance and determination, from April to September, you can add fertilizer to the irrigation water, every 12-15 days, choosing a fertilizer for acidophilic flowering plants, which contains a good variety of microelements.
