This is a case when folk remedies work, but only make things worse for a delicate houseplant.
Pelargonium is grown by many housewives. The plant is distinguished by its extraordinary beauty and specific smell.
Some gardeners advise to reveal the potential of pelargonium with the help of fertilizers.
Often this list includes not only complex fertilizers that contain nitrogen, phosphorus, potassium, manganese, copper, biologically active substances (vitamins and succinic acid), etc.
Often the list includes products that are not logically related to gardening. Of course, this does not exclude the possibility of their use. For example, many people use potassium permanganate to disinfect soil and seeds.
But folk remedies are not always good. For example, it is not recommended to feed pelargonium with iodine and hydrogen peroxide. Gardeners do not doubt the effectiveness of the first component, but peroxide does not bring any benefit to the plant.
Iodine enhances flowering, but then there is a decline. Pelargonium drops buds and begins to wither. Often, such an effect is a consequence of excessive use of iodine. Everything should be in moderation.
But experienced gardeners advise to refuse iodine and other similar means. For pelargonium there is nothing better than a complex fertilizer, which already contains all the necessary macro- and microelements.
