Can you grow hairy cuckoos in the Northeast, and is it easy to raise hairy rhododendrons?

No way. Summer in the Northeast is actually quite hot.

It grows, shrinks, and even dies.

Unless you have a good temperature regulation.

Cultivation techniques of hairy cuckoos.

Potting soil. It likes acidic soils, requires looseness, good drainage, and is rich in humus. Take 4 parts of humus, 2 parts of old potting soil, 1 part of sandy soil, fire soil, and sawdust, add an appropriate amount of cake fertilizer and mix well, and pile it for half a month to use.

Potting. When potting, the seedlings are more with soil, less damage to the root system, the roots that are too long are appropriately shortened, and the larger plants should be pruned on the upper branches. First cover the drainage hole at the bottom of the pot with broken tiles in the pot, lay a layer of coarse-grained soil as a drainage layer, fill in part of the culture soil, put the plant into the pot to straighten, and add soil compaction.

The planting depth is comparable to the depth of the original seedlings when they were unearthed. Water thoroughly.

Watering. Afraid of both dry and waterlogged. From the end of November to the middle and early February of the following year, most of the open-field potted azaleas are dormant or semi-dormant, and they are watered appropriately depending on the dry and wet conditions of the potting soil.

In late February, the temperature rises, flower buds and leaf buds germinate, and the number of watering is increased appropriately. 3 June is the vigorous growth period of new shoots, and the water demand increases, so the number of watering should be increased as appropriate. 7 September when the temperature is high, it is necessary to water every day.

After October, the amount of watering can be reduced.

Fertilize. If you don't like big fertilizer, you should apply thin fertilizer frequently. Long-acting fertilizers, such as cake fertilizer, bone meal and organic fertilizers such as dry manure manure, are used for base fertilizer and are buried in potting soil in the pot or winter.

Top dressing with fast-acting fertilizer, such as human manure organic fertilizer or nitrogen, phosphorus, potassium fertilizer, from the beginning of spring to before flowering, apply phosphorus and potassium fertilizer 1 2 times a month, and stop fertilizing when flowering. Apply 1 2 times of phosphate fertilizer-based liquid fertilizer after the autumn cool, and stop topdressing after winter.

It prefers cool, moist and sunny environments. Cold-resistant, heat-sensitive, semi-shade-resistant, not resistant to long-term strong light exposure. The growth temperature is 15 28, and the winter can withstand -8 low temperatures. The soil is fertile, loose and well-drained acidic sandy loam.

Ecological habits of hairy cuckoos.

It prefers cool, moist and sunny environments. Cold-resistant, heat-sensitive, semi-shade-resistant, not resistant to long-term strong light exposure. The growth temperature is 15 28, and the winter can withstand -8 low temperatures. The soil is fertile, loose and well-drained acidic sandy loam.

1. Seedling: five methods can be used: cuttings, grafting, stripping, branching, and sowing, and the most common method is the use of cuttings in the orange family, and the rhododendron propagation method is mainly cuttings. Before and after the selection of new branches, 5 cm to 10 cm long, cut at the fork point, peel off the lower leaves, leave 3 to 4 top leaves, insert 1 3 of the branches into the soil, spray enough water, cover with plastic film, usually strengthen management, transplant after one year.

2. Environmental conditions: It is best to cultivate azaleas in two environments: indoor and indoor. The indoor environment is used in winter.

Outdoor venues, used in summer and autumn, are better on mud floors than cement floors. The site should be spacious, ventilated and shaded, and a shade shed should be built on it, covered with reed curtains or sheltered by borrowing natural shade, and the light transmittance should be about 30{bf}, and sunset should be avoided.

3. Potting soil requirements: Rhododendron likes loose soil, strong permeability, good drainage of mega rotten masses, and acidic soil rich in humus, with a pH value. If you use clay or alkaline soil, it is difficult to survive.

In particular, summer cuckoos and cuckoos must be in the mountains. The mountain soil also needs to be transformed, and at present, three kinds of prepared culture soil are usually used.

4. Flower pot selection: The flower pot for cultivating azaleas is generally used in mud pots and purple sand pots. The mud pot has good aeration and water permeability, and this pot is used in the cultivation of production units.

Shaped rhododendrons, especially the rhododendrons that have been shaped, are generally planted in beautiful and elegant purple sand pots for indoor and outdoor furnishings, and the purple sand pots have delicate texture, rich colors, beautiful shapes, and can double the ornamental value.

5. Transplant the upper pot: Attention should be paid to the drainage layer, first cover the drainage hole with tiles, and then put in 1 3 coarse soil particles, and slightly add fine soil. Then put the rhododendron seedlings in, straighten the seedlings with one hand, and fill the pot with soil with the other.

Fill the soil attention can only be filled to 2 cm under the pot mouth, not too full, so that in order to water in the future, and finally the pot around the solid, shake the pot, so that the pot surface is flat.

6. Watering requirements: It is best to use rainwater for watering rhododendrons, followed by river water and pond water. If tap water is used, it is advisable to store the water for 1-2 days to allow the chlorine to evaporate before use.

Add ferrous sulfate when using, water once every 7-10 days during the growing season, and use it regularly to ensure that the soil is acidic.

7. Fertilizer and water management: Rhododendron likes shade and dampness, and should not be too dry. More water is especially needed during flowering. Winter rhododendrons have entered the dormant period, the water demand is not much, generally every 4-5 days watering 1 time, should be carried out around noon on a sunny and warm day.

Rhododendron tomentosa is easy to raise, when breeding, it will be planted in acidic soil with good drainage, and water the plant every 3-7 days, so that the soil can maintain a moist state inside, so that the normal growth of Rhododendron tomentosa, if you want the plant to grow more rapidly, you need to apply a compound fertilizer after diluting the early locust every 15 days for Rhododendron tomentosa in its growth period.

1. Easy to raise

Rhododendron hairy is easy to raise, rhododendron hairy is one of the easier varieties of rhododendrons, the plant likes a cool, moist and ventilated growth environment, so the rhododendron does not need a lot of sunlight, it can be maintained on the indoor windowsill, and the plant can be provided with about 6 hours of scattered light every day.

2. Provide soil

Rhododendron tomentosa prefers loose, fertile and well-drained acidic soil, which can be planted in a mixture of humus, river sand and pine needles.

3. Replenish water

Rhododendron hairy rhododendron in the process of growth, the demand for water is larger, generally need to be watered every 3 days, when the summer is hot, it is best to water once a day in the morning and evening, so that the soil humidity is about 50%, note that the rhododendron is not resistant to waterlogging, and it needs to be watered every 7 days in winter.

4. Apply nutrients

When the rhododendron is in the growth period, it is necessary to apply diluted nitrogen, phosphorus and potassium fertilizer every 15 days, and before the rhododendron flowering stage, it is necessary to apply phosphorus and potassium fertilizer once to promote the flowering of the plant.

Rhododendron hairy, also known as Rhododendron hairy or Rhododendron macrophylla, is a small evergreen shrub. The flower shape is beautiful and generous, it is a common horticultural flower, and is often used in the decoration of public parks. And Rhododendron tomentosa can also be used as medicine, which has the effect of lowering lipids and blood pressure, and can also prevent the three highs, and has a beauty effect.

So how to breed rhododendrons, we should start from the aspects of soil, light, temperature, watering, fertilization, pruning, pests and diseases, let's take a look at it specifically.

1.Soil. It is best to plant it in acidic and fertile soil that is loose, breathable, and well-drained.

The soil of Rhododendron hairy leaf can be cultivated according to 4:2:1:4:4:2:1:

In order to increase the nutrients of the soil, an appropriate amount of cake fertilizer can be added.

2.Illumination. Rhododendron hairy leaves like light, and it is necessary to give them sufficient light. However, it is best not to expose the plants to strong light for too long, and it is best to maintain them in a semi-shaded and sunny environment such as balconies and window sills.

3.Temperature. Rhododendron prefers a cool and pleasant growing environment, and the most suitable temperature range for its growth is 15 to 28. Rhododendron tollifolia is resistant to low temperatures and can survive in a -8 environment, but it is not resistant to high temperatures, and it should be cooled down when the temperature is too high.

4.Watering. The watering of Rhododendron hairy leaves should be dry and wet, and it is necessary to pay attention to the dryness of the soil, and pay attention to watering when the soil is dry.

When the temperature is too high in summer, you can do it once a day, and when winter comes, you should reduce the frequency of watering, and you can do it once every 4 or 5 days.

5.Fertilize. Fertilize Rhododendron tomentosa in small amounts and many times, and be careful not to have too much fertilizer or too high fertilizer concentration, which will have adverse effects on Rhododendron tomentosa.

Generally speaking, in the growth period, apply fast fertilizer once every half month, and once before and after flowering, you can fertilize each tree, and you don't need to fertilize when winter comes.

6.Trim. When Rhododendron tomentosa is in the growth period, it is necessary to pay attention to topping and pruning to promote its growth. When pruning, pay attention to pruning diseased and weak branches and dead branches to ensure the nutrient supply of main branches and leaves.

7.Pest.

Rhododendron hairy leaves are susceptible to the threat of pests and diseases, so it is necessary to control them in time. Pests and diseases such as brown spot, root rot or red spider will seriously threaten the normal growth of the plant, so it is necessary to find it in time and use it as soon as possible, and when it is serious, the drug can be applied.
