Problems of growing indoor plants. Part 1.
Floriculture is a troublesome business. Inspecting the plants from time to time, you can notice spots on the leaves, yellowing, discoloration. But they get sick and do not necessarily fade due to pests, often the reason for this is incorrect conditions for the maintenance of plants, careless care of them leads to physiological diseases. Symptoms usually appear suddenly. First, one organ is affected, gradually spreading, captures the entire plant. Do not immediately grab onto the spray bottle with an insecticide, it is better to watch the “suspicious” plant for several days before starting to treat it.
What are the problems with growing plants? Consider the main ones.
Avitaminosis - manifests itself in yellowing of leaves, in the pallor of leaf blades, while the veins remain green - this is chlorosis or iron deficiency. If the veins are surrounded by a yellow halo, this is a manifestation of a nitrogen deficiency. Yellow specks on the leaves, and flowering and plant growth slowed down - little potassium.
The reasons for vitamin deficiency are that the plant lacks mineral substances, or it does not absorb them.
Help consists in watering low-lime water and using balanced fertilizers.
Tip: To the substrate, add organics based on algae and manure 5-20%, depending on the type of plant.
Dropping buds - Gardenia and stefanotis are particularly susceptible to this, it happens that intact or shriveled buds do not understand why they fall from plants ready to bloom.
There are several reasons for this: whether the plant is in a draft or too cold water for irrigation, a big difference between day and night air temperatures. The plant was transplanted when the buds were already formed, or the purchased plant was transported in uncomfortable conditions for it.
Help consists in placing a plant ready for flowering in a place with suitable conditions, where the temperature is not lower than 18 ° C and humidity is 60% or higher. Reducing the concentration of fertilizers and frequent watering will also benefit him.
Tip: if buds appear on the plant, do not change the position of the pot even when harvesting or for watering.
Dropping flowers - lush, not wilted corollas suddenly begin to fall from a plant in bloom.
The reason for this phenomenon is the dry air in the room and the excessively high temperature. Lack of water and drafts have a bad effect on the condition of the plant.
It is possible to help “sick” pets by maintaining the optimal temperature regime of the air, during the day - no higher than 20 ° C and no lower than 15 ° C - at night, and for cold-loving (bluebells, cyclamen, azaleas, cinecaria, primrose) even 12-14 ° FROM.
Tip: flowering plants can not be sprayed! Due to water droplets, spots appear on the petals, they wither and fall off.
Burns on the leaves - first, discolored areas appear along the edges of the leaves or along the veins, then they turn brown, become dry and brittle, while the rest of the leaf blade “wrinkles” and becomes wavy.
The reasons for this problem are frequent fertilizer, its excessive concentration, or the fact that the plant is in direct sunlight. Too chlorinated or contaminated water for irrigation can also cause burns.
You can help the plants, if you do not leave them in the sun during the hottest hours, give them a rest from fertilizers for at least 2 months. Then use only fertilizers with a low nitrogen content, reducing the dose (1 cap per 6-8 liters of water) and applying them every 2 waterings. Moreover, “candles” or granular fertilizers are best used for freshly transplanted plants.
Tip: In no case do not spray plants standing under the scorching sun, as drops remaining on the leaves, like lenses, will cause burns on them.
Leaf darkening - brown patches appear first at the ends of the leaves, gradually capturing the edges of the leaf blades, they dry and fade. A wilted plant may begin to rot.
The reasons are in cold or dry air. Such a symptom may result from a burn. If the plant is flooded, or the substrate has caked so much that the roots "do not breathe."
Help the plant by spraying the leaves and place the pot on wet gravel or expanded clay. Better yet, when darkening limp leaves, do not water the plant for 10 days or longer, after which change the substrate by replanting the plant and pruning the root areas
Tip: the plant should be replanted at least every 2 years, as the earthen cakes coalesce under the weight of water during irrigation and “strangle” the roots.
Leaf discoloration - the color of several leaves changes, or they turn pale in some places.
The reasons for this are as follows: very low air temperature or its sharp drops, cold drafts, inappropriate soil — an “empty” substrate.
The help to the plant in this case is as follows: separate it from others and observe its “behavior" for 10 days without fertilizing, watering or exposing the "diseased" plant to direct sunlight.
Tip: it is necessary to check the conditions of the plant, if they do not meet its needs, then discoloration of the leaves is only one of the first symptoms of a plant's disease.
