Houseplants need additional power supply much more, than plants of the open ground. The soil in pot of any size is exhausted within two months. Further nutritious elements are necessary for plant for normal life.
As plants eat
Power supply of plant is received from the soil – "get" it by means of roots from there. Liquid "food" is acquired by them quicker. Therefore for fertilizing of houseplants it is necessary to get or prepare nutritious solution. Fertilizers in granules or in powder - the slowed-down action - can be brought before landing. Abundant postlanding watering will dissolve them and will make digestible.
It is the best of all to buy ready fertilizers in solution, according to requirements of any given houseplant as at different types of plants of requirement different.
What fertilizing happens
There is universal fertilizing which is suitable for any room and even garden plants. But in them, mainly, basic element is nitrogen. And plants need not only nitrogen, but also potassium, fluorine, copper, zinc and other substances.
Besides the general health of all plant, fertilizing it is possible to control development of its separate parts. Such fertilizing is called extra root and is brought locally, spraying of leaves or stalk. They can influence development of sheet weight or stimulate blossoming. Extra root fertilizing for young plants, up to one year of life is most effective. Foliage of adult window plants acquires them worse.
It is necessary to feed up plants only during vegetation, that is only when they actively grow and blossom. During dormant period any fertilizing is categorically contraindicated.
What is not enough for plant
How to learn, than it is necessary to feed up any given flower? The lack of any element affects exterior of plant. If it lacks nitrogen, the growth inhibition and pallor of leaves is observed. If there is not enough phosphorus, foliage darkens, and blossoming poor. If in the soil there is not enough potassium, blossoming in general can not occur – everything goes for development of leaves and stalk.
All houseplants, except for bulbous and klubnelukovichny, need periodic introduction of organic chemistry. It not only their main "food", but also good way to make soil more friable, having improved thus access of air to roots. For organic fertilizing of window plants the bird's dung is used (1 tsp gets divorced in water liter) or mullein (2 tsps on water liter).
Houseplants of times in three months it is good to feed up cindery solution (1 tablespoon of ashes infuses week in boiled water liter).
Many flower growers against chemical fertilizers also prefer to manage house means. Fertilizing by sugar, infusion of onions peel, orange peels, shells from eggs, coffee, tea, certainly, is possible, but is less effective. It is necessary to carry out such fertilizing more often – two times a month. And the egg shell can cause chloroz in some species of window plants, such as azalea and gidrangeya. As for weak tea and coffee, it is more likely not fertilizing, and soil baking powder that, certainly, is useful, but does not give power supply to plants.
