Rhododendron is often referred to as mountain pomegranate, its branches are more lush and colorful, thanks to its excellent growth rate, can be pruned many times a year, so you can choose different pot shapes according to your own preferences, there are rhododendrons on the lakeside, garden and creek. The following is to introduce the problems that azaleas need to pay attention to in the summer maintenance, and see if everyone has done it.
<h1 class="pgc-h-arrow-right" >· </h1>
Rhododendron likes to be wet, summer high temperature and heat on the foliar water evaporation too fast, potting soil is easy to dry, if the watering is not timely, it is easy to dehydrate the plant, causing the phenomenon of yellow leaves falling off, so when the weather is hot and dry, water should be watered 1 to 2 times a day, and spray water around the foliage and potting to cool down.
In addition, you can also put a long wooden board on a large pot filled with water, and put the rhododendron pot on it, which can maintain the humidity around the pot and play a cooling effect!
<h1 class="pgc-h-arrow-right" >·proper shading· </h1>
Rhododendrons can grow healthily under the illumination of scattered light with little light intensity, but the light intensity in summer is too large, the new leaves are easily burned, the edges are dry and black, and the plant is at risk of death in severe cases. Therefore, in the summer, the rhododendron should be shaded, not exposed to the sun at noon, and placed in the sun before eight or nine o'clock in the morning to receive scattered light to meet the needs of plant growth.
<h1 class="pgc-h-arrow-right" >3 · fertilization · </h1>·
The flowering period of rhododendrons is from April to June of each year, when rhododendrons consume much more nutrients than usual, so it is necessary to supplement the appropriate amount of nutrients.
In the process of flowering, you can topdress once every 12-15 days to ensure the normal flowering of rhododendrons, it is recommended to use [Delle Manyuan Flowers]; and after entering July, it will begin to slowly reduce the number and dosage of fertilization, because the high temperature will make the rhododendrons enter a specific dormant state, and the demand for nutrients will be less. Foliar fertilizer using COMMO Schilder amino acids.
【Dai Le Man Garden Flower】
1. It can quickly replenish the nutrients lacking in plants, and the absorption and utilization rate is far greater than that of inorganic nutrients.
2. Obviously promote the differentiation of crop flower buds, and have a very good effect on flower preservation and fruit preservation.
3. Effectively solve the leaflet disease caused by zinc deficiency in plants.
4. Improve the stress resistance of crops, and have a good preventive and alleviating effect on nutrient-deficient diseases such as root rot.
【Amino acid foliar fertilizer】
1. Rich in plant-derived amino acids and highly active polypeptides, it promotes the rapid absorption and utilization of crop nutrients;
2. It contains photosynthetic induction substances, improves the net photosynthetic rate of leaves, and provides sufficient photosynthetic products for crop growth and development;
3. Enhance the crop defense mechanism, improve the resilience of crops to stress, and reduce the damage to crops from low temperature, drought and other adversities.
<h1 class="pgc-h-arrow-right" > · reasonable pruning · </h1>
Summer culture gardenia can be less thin fertilizer, after the flowering period cut off the residual flowers, supplemented with a COMMO Schnoord compound fertilizer, to promote the rapid growth of roots and new branches. If it is a farmed gardenia, after the new branches mature, there will continue to be flower buds, which requires us to give more [Daile Manyuan Flower] before the flower bud differentiation.
【High-tower nitrothio compound fertilizer】
15-15-15、20-5-15、15-5-23
1. Highly active biostimulant, improve crop stress resistance, and can "prevent disease" nitro fertilizer
2. Promote nutrient absorption and transport, and "increase production and improve quality" of nitro fertilizer
3. Schnodder DMP technology, stable and long-term effect, "not afraid of the end", "fruit shoots with the promotion" of nitro fertilizer.
<h1 class="pgc-h-arrow-right" > Wu · ventilation · </h1>
Ventilation conditions must be good, poor ventilation, will cause many problems to the cuckoo, such as dry leaves, leaves appear spot disease and the like, because the ventilation is not good, the air humidity is relatively large, he is easy to cause bacterial infection, easy to cause rotten roots or leaf spot disease, or dry tip fallen leaves.

Iron deficiency yellowing disease often occurs in the northern region of the soil with alkaline soil, and when the disease is mild, the plant will appear late greening; in severe cases, the leaves can all turn yellow and the leaf edges are scorched.
Prevention and control methods: timely improve the iron properties in the soil and reduce the alkalinity of the soil. Increase the application of organic fertilizer to improve the soil. Iron-deficient plants can also be sprayed directly with Zhixin Bright Green, spraying every 10 days until the leaves return to normal.
【Zhixin Bright Green】
1. High content:
It is refined by the citric acid chelating process obtained by the United States patent, and the iron content is ≥ 20%;
2. Fast high solubility:
Can be quickly dissolved in water or more concentrated liquids;
3. Quick-acting and easy-to-absorb:
Strong adhesion, fast penetration, easy absorption, very obvious crop fertilizer efficiency;
4. The effect of increasing production is obvious:
When the soil is deficient in iron, it can increase the yield by 10%-20%, and the input is less and the effect is fast.
After the rhododendron gets root rot, the growth condition is not good, the leaves are wilted, or even dried up, and the surface of the root system appears water-stained brown patches, which are seriously gradually decayed and peeled, and the woody part begins to turn black. Root rot is generally the most likely to occur in environments with high temperature and high humidity. The control method is to thoroughly disinfect the cultivated soil before turning the pot, and keep the soil loose and breathable, moist, so that it has good permeability to avoid water accumulation.
Prevention and control methods: If the plant is found to be sick, it is necessary to turn the pots and change the soil in time. During treatment, [Manqi + ZhongshengBujin + Daile Rooting Liquid] washed the diseased plant and re-potted.
【Manqi】

2, the crop is very safe, flowering, young fruit can be applied.
3, good mixing.
4. It has inhibitory effect on leaf mites and pathogenic nematodes.
【Daile Rooting Solution】
1. Greatly improve soil organic matter, improve soil agglomerate structure, and play a role in fertilizer preservation and preservation.
2. Balance soil pH, improve soil microbial environment, root, root, root, and reduce soil-borne diseases.
3. Solve soil salinization and reduce the harm of soil salinization.
4. Specially add biologically active coenzyme factors to improve crop stress resistance, drought resistance, disease and pest resistance.
The adult reticulum bug is small and flat, about 4 mm long, black, and is a pest that is the most harmful to the evergreen rhododendron, often sucking leaf liquid on the back of the leaf, and yellow-white spots appear on the leaf surface of the victim, causing the leaves to fall off, causing the tree to weaken and affect growth and flowering.
Prevention and control methods: mainly spraying with drugs. Spray with [thiamethox, isopropylvir + prazidone], pay special attention when spraying, spray the grass on the back and sides of the leaves, spray once every 7 to 10 days, 3 times continuously.
【Thiamethox, isopropylvir + prazidone】
