my spartifilium plant has small leaves and grows little what can i do?
the reasons for which a plant remains very small are various, and generally depend on the conditions of cultivation; if the plant is still healthy, without ruined foliage, it means that the waterings are correct and the environmental humidity is sufficient, as well as the lighting. The other element that influences the development of a plant is the availability of mineral salts in the soil, in fact, as also happens for humans, in addition to sunlight, plants also need some mineral salts to be able to develop better, otherwise growth is slow, as happens to children when they do not include foods rich in mineral salts and vitamins in their diet.
The first thing to do is to repot your spoonbill; if the roots tend to come out of the pot, you can choose a container slightly larger than the one in which the plant is now, without exaggerating, however, because these plants do not like to find so much space in which to grow; buy in the nursery a good universal soil, rich and soft, which is also able to slightly retain humidity; fill the pot well and bury the plant, taking care not to damage the root system; from time to time, while repotting, tap the container lightly on the table, to allow the air to escape, thus avoiding the formation of harmful air pockets.
Once repotted, the plant starts again with your normal watering; in about a month you will also be able to resume with fertilizations, since in general the soil is already fertilized. Choose here also an excellent quality fertilizer, specific for green plants, therefore it contains a good quantity of nitrogen, less phosphorus and potassium; nitrogen, phosphorus and potassium are the macroelements necessary for plants, the quantity contained in the fertilizer is indicated by numbers close to the abbreviation NPK (N = nitrogen, P = phosphorus, K = potassium). In addition to macroelements, various microelements are also very useful to plants, such as Boron (B), Copper (Cu), Iron (Fe), Manganese (Mn), Zinc (Zn); a good quality fertilizer in addition to nitrogen, phosphorus and potassium, should also contain these trace elements. Fertilizers are generally supplied every 12-15 days, from March to September, dissolved in the irrigating water. If you are a guy who forgets about fertilizers, try to mark on the calendar the days when you should add them to the water; or, instead of a fertilizer to be supplied periodically, choose a slow release fertilizer: these are products in granules or bars, to be lightly buried on the surface of the pot; a single supply lasts for at least four months, and dissolves progressively with each watering.
