Scientists at NASA have done research and found that many common household plants can quickly and effectively purify harmful substances in confined spaces, making indoor air fresh and improving the living environment. And plants are never outdated interior decoration, raise some green plants at home, good-looking and environmentally friendly.

The following Rain editor will do some homework on indoor green plants and planting tips that are easy to feed and purify the air, so as to give a reference to those friends who want to recommend them.

Peace lilies are very suitable for growing indoors, even if they are not exposed to the sun or their owners often forget to water them. Of course, the most suitable growth environment is between 60-75F at room temperature, preferably above 50F at night. Heping lilies prefer indirect light (such as 6-8 feet away from the window), which can easily make the leaves yellow or even wither. When you see its leaves drooping, you know it's time to water it.

Dragon blood tree is also slightly poisonous, if there are pets and children at home, you should pay attention to it.

Tips for indoor planting

1. Use suitable flowerpots and flower paste

(the picture is reproduced from mustangrobotics.club and the copyright belongs to the original author)

Potted flowerpots usually have a drain at the bottom to ensure that excess water can flow away. For plants with too much water that can easily cause rotten roots, if a tray is used to pick up water under the flowerpot, the excess water must be poured out after watering. Plants that do not need too much water choose breathable pottery pots, while plants that need to retain a lot of water should choose plastic flowerpots. If plastic flowerpots are not atmospheric enough, you can set other decorative flowerpots on the outside.

The flower paste used for potted plants is called Potting Mix/Potting Soil, which is very different from the composition of Garden Soil/Top Soil used for outdoor planting. Potting mix, also known as soilless mix, is mostly a mixture of peat moss, pine bark, coconut shell, perlite and vermiculite. It is lighter and more hydrophobic than outdoor flower paste, and is more suitable for relatively sealed containers such as flowerpots.

If you put the outdoor flower paste in the flowerpot, it will do more harm to some plants that are easy to rot their roots because of too much water, and this kind of flower mud is more likely to deposit and agglomerate after a long time, which is not conducive to plant growth.

two。 Suitable fertilizer

The amount of fertilizer applied in potted plants is also very important, the lack of nutrients and slow growth, but too much fertilizer will also hurt plants, usually only in the fast-growing season, new pots, winter do not apply fertilizer.

(the picture is reproduced from Barton "s Greenhouse and Nursery, and the copyright belongs to the original author)

The ratio of N-P-K (nitrogen-phosphorus-potassium) is listed on fertilizers. Nitrogen mainly promotes the growth of green leaves, phosphorus mainly promotes the growth of roots, flowers and fruits, while potassium promotes overall health. Generally speaking, a balanced ratio of 10-10-10 general-purpose fertilizers is suitable for most indoor plants.

Pot fertilization is usually best to use water-soluble fertilizer, this fertilizer is easy to dilute, can be fertilized as needed, after all, the amount of large and small pots will be different.

There is liquid potted fertilizer, which is very easy to use. There are foam fertilizers specially designed for succulent plants, and some slow-release fertilizer bars that can be inserted directly into the soil are also favored by many people, because they don't have to be used once for months, and they are also very convenient to use.

● Miracle-Gro 's potted slow-release fertilizer rod NPK ratio is 6-12-6, which is more suitable for plants that need to blossom and bear fruit, which can last and effectively supply fertilizer for 2 months.

● Jobe "s potted slow-release fertilizer bar is very cost-effective, 2.50 sticks, each lasting for 2 months. The NPK ratio of this potted fertilizer is 13-4-5, which is more suitable for the growth of foliage plants or leafy vegetables.

3. Suitable environment

Plants have their own suitable growth environment requirements, some plants are adaptable, some plants need to be taken care of carefully. However, even rough plants have conditions that they can't resist, such as succulent plants that many people say can't die. If you keep watering them, you can also water them to death.

So when buying plants in the store, it is best to take a closer look at the back of the label, which will indicate some plant attributes and planting points, such as how tall you can grow, how much sunlight you need, temperature requirements, frequency of watering and fertilization, how to take care of it, and so on. It is important to know whether you can offer such an offer.

Most of the plants that can be used as houseplant are in the range of room temperature suitable for people to live, and many of them are not resistant to cold. Be careful not to put the crops by the ventilated window in cold weather so as to avoid freezing.

5. Moisture content

(the picture is reproduced from Business Insider and the copyright belongs to the original author)

The roots of plants also have to breathe. If there is too much water in the flowerpot, it is easy to "drown" the roots. Each plant has different requirements for water, for example, succulent plants like very dry sandy soil, so watering once until the mud is dry does not need to be watered a second time; other plants, such as Fiber-optic plant and windmill grass, like very wet soil, which generally cannot be watered; but most plants require water not to be too dry or too wet.

So for most ordinary potted plants, the easiest way to water is to wait until the surface soil is dry, so that the bottom layer is still wet, which ensures that it will not be too dry, but it will not be soaked all the time.

In addition, for ordinary potted plants, you can also use some automatic watering tools that slowly release water into the soil through thin tubes.

In addition, some plants like the humid air environment, but most of the air humidity in the home is not enough, we should pay attention to some, especially do not put plants in such a particularly dry position as heating vents.

In some areas, the quality of tap water is hard, or fluoride is added, and the fluoride or salt in the water can easily harm plants, so if the water quality is not good enough, it is best to breed it with pure water or filtered water. It would be better to let the water stand for a while before watering, and it would be better to water the cover after it reaches room temperature.

6. Insect pest

Many plants will also attract some small insects, using insecticidal soap spray can safely and effectively remove aphids, mites, mites, leafhoppers, wood lice, scales, thrips and whitefly and other pests, and solve the problem. and insecticidal soap is an approved way of killing insects in organic cultivation, and it can also be used on fruits and vegetables.

For example, Miracle-Gro has this spray that can be used directly.

Friends who want to save money can also buy the concentrate and dilute it with water. The concentrate of 16oz can make 6 gallons.
