1、 Orchid

Orchids often have problems. The leaves are dry and yellow, and the leaves are no longer flat. Many flower friends say it's a problem of watering. Watering is indeed one of the reasons, but the symptoms of orchids we can see are actually the display of problems in the roots of orchids. Because there is a problem with the root of the orchid, the orchid cannot absorb nutrition, and the whole orchid will have all kinds of problems

Orchid empty root & amp; Rotten root treatment

Empty roots and rotten roots are also common problems of orchids. There are many reasons for the emergence of empty roots and rotten roots. Many people say that it is because the root system of orchids is not in complete contact with the soil. In fact, this only tells the surface reason, and the deeper reason is the breeding of microorganisms. So how should we deal with the rotten root and empty root

▶ Rotten root

1. Cut off all rotten roots

▶ Empty root

And what is an empty root? The empty root is the fleshy root of an orchid, leaving only a layer of skin on the surface. And a short fiber inside

How to avoid rotten orchids and roots

The treatment method of empty roots is the same as that of rotten roots. All the root systems that have been damaged should be cut off, and then re rooted and put into the basin. The steps are the same as above. Huahua will repeat here

How to raise roots

It is almost a consensus that raising orchids should be rooted first. Then, how to raise orchids

1. The soil is well configured, loose and breathable, and the water will not accumulate. The respiration of the root is normal. Naturally, it can greatly reduce the risk of rotten roots and let rotten roots grow in a good environment. The simplest soil formula is rotten leaf soil + river sand, with a ratio of 3:2, or 50% rotten leaf soil + 50% perlite

2. Colonization is not to let the soil and roots have gaps. During colonization, hold the orchid plants, and then fill them with soil. Don't fill them too full at one time. First knock gently, so that the soil in the flowerpot can fully contact the orchid roots, avoid gaps, and effectively prevent empty roots

3. The orchid basin should be appropriate. Remember to use a large basin for small plants. It is easy to accumulate water after watering the large basin, which is unfavorable to the growth of orchid roots

4. Watering is the key point. Generally, orchid plants should be watered when they are dry. If the novice is not sure, don't dislike the trouble. Remove the planting material on the basin surface to a depth of two or three centimeters. If the soil is dry, it means you need to water it immediately. If it is not dry, you can water it in another day or two. When watering, the whole basin must be watered thoroughly. Don't stop when the water flows out of the gap under the clump. You can pour more water for a while, so that all plant materials can "eat" water

5. Light is indispensable for any plant. In spring and winter, it can be illuminated all day. In summer and autumn, if you feel uncomfortable and too dry when you are in the sun, it means that your orchids also need proper shade

6. Fertilizer, the root system of orchid has been absorbing the nutrients in the soil. If you don't fertilize it until the nutrients in the soil are consumed, it's difficult for orchid to grow up. For robust orchids with vigorous growth, thin liquid fertilizer can be applied every 10-15 days. Pay attention to the uniform content of nitrogen, phosphorus and potassium

If you don't think you can grasp the weight and timing of fertilization, you can choose to spray fertilizer on the leaf surface, so that the fertilizer will not contact the root and cause fertilizer damage. It is the best fertilization method for orchids. During the growth and development period of orchids, apply fertilizer on the leaves once every 10 days, with 1:1000 potassium dihydrogen phosphate and 1:1000 boron fertilizer

Aloe liquid can also be used. Aloe contains a large number of nutrients such as polysaccharides and amino acids, and more than 20 minerals, which can meet the nutrients required by orchids. Moreover, aloe contains remote aloe tincture, which can kill almost all bacteria and viruses. There is no need to apply pesticides to prevent diseases after application

7. Regularly cut off the diseased root, rotten root and empty root. On the one hand, it can be carried out when pouring pots and changing pots at ordinary times

2、 Chlorophytum

Chlorophytum is almost one of the necessary plants for novice flower growers, but Chlorophytum has many problems. For example, Chlorophytum is easy to dry its leaf tips, turn yellow, wilt, and even die. In the final analysis, there is something wrong with the root system of Chlorophytum. Whether it is improper watering or improper fertilization, the root system of the plant is destroyed first

Root growth

The propagation of Chlorophytum is very simple. You can directly separate the seedlings on the Chlorophytum stolon, but the survival rate of simply inserting the seedlings into the soil must be very small. Before colonization, Huahua suggested that Chlorophytum take root first

1. First prepare a Chlorophytum with stolon. If there is air rooting on the young plant, it is the best. If not, it doesn't matter

2. Cut a plastic bottle and adjust its position so that the plastic bottle can be placed about 20 cm below the aerial rooting of Chlorophytum young plants. Then add water to the bottle and control the water level to about 10 cm below the air root of Chlorophytum. The air root of Chlorophytum cannot be soaked in water

3. Put the Chlorophytum in a sunny place and wait for it to take root~

4. After Chlorophytum takes root, adding appropriate nitrogen fertilizer to the plastic bottle can promote the growth of Chlorophytum

5. When the root system of Chlorophytum grows out, the stolon can be cut off. When cutting, it should be close to the young plant. Then put the Chlorophytum on the basin

In addition, there are flower friends who provide their own methods, that is, cut off the young plants of Chlorophytum directly and throw them into the water, and it will slowly take root by itself

How to raise roots

1. Light, Chlorophytum likes light, but Chlorophytum doesn't like strong light, but scattered light, so it's the best choice to put it in a brighter room

2. Temperature: the suitable growth temperature of Chlorophytum is 15 ~ 25 ℃, and the room temperature in winter should not be lower than 5 ℃. If the temperature suitable for growth cannot be guaranteed, Chlorophytum will die directly, where can it grow roots

3. In terms of watering, Chlorophytum likes water, but it is afraid of ponding. Its root system is also a fleshy root with strong water storage capacity, so it can withstand drought. If you want Chlorophytum to produce new roots, you can first clean up the old roots and withered roots, and then control the water. In order to absorb enough water, Chlorophytum will begin to produce a lot of new roots. Here we should pay attention to Oh ~ we must trim the old roots before controlling the water, otherwise the new roots will be born on the basis of the old roots. The ability of the old roots to absorb nutrition and water is relatively weak, which will directly limit the absorption ability of the new roots

4. Chlorophytum is a fertilizer tolerant plant. For Chlorophytum that has begun to grow small plants, nitrogen based topdressing can be applied every half a month, which can promote the growth of Chlorophytum. If it is a well-growing Chlorophytum, it can also be applied without fertilization

5. Soil, Chlorophytum likes to transport fertile sandy loam, which requires the soil to contain humus and have strong permeability. Huahua recommends that when you plant Chlorophytum potted plants, you can mix rotten leaf soil or peat soil, garden soil and river sand, and add a small amount of base fertilizer as the substrate

6. Generally speaking, the pots of Chlorophytum should be changed once every 2-3 years, but in the specific maintenance, if your flowerpot is obviously insufficient, you can change the pots of Chlorophytum in March, and properly remove the old roots, residual roots and diseased roots when changing the pots

3、 Crab claw orchid

The flowering time of crab claw orchid is winter. In the winter when everything withers, it is also a beautiful scenery. However, crab claw orchid has a problem. Its root system is fragile. If it is not grafted, its root system will be more fragile

1. Prepare a piece of crab claw stem and dry it in a cool and ventilated place for 1 ~ 2 days~

2. Prepare a hydroponic Tour
