Is camellia not suitable for planting on the roof of a tall building?

It's windy, easy to dry, and it's not easy to plant (your home is **?). ）

I am Yueqing, Zhejiang, on the 6th floor of the roof planted a few camellia are fine, especially planted in the brick 20 cm high small flower bed in the camellia, because the soil is not easy to dry, the root system is not limited, the growth is particularly good. (It turned out that my relative planted it in a flower pot, and because he turned over the pot every year, he was not very energetic when he moved it).

Plant the roof, one is to pay attention to watering, one is to pay attention to sun protection, it is best not to use black glaze pots (this kind of pots in the summer sun quickly hot, burn the root system of the pot wall), use a larger pot, use loess (of course, ordinary soil can also be), just planted to water the water, turn the pot do not go to a lot of old soil.

Yes, strong winds do not guarantee humidity. South of the Yangtze River can. It is also necessary to shade in the summer.

Camellia grows at a temperature between 20 and 25, stops growing when it is above 29, and the leaves will be scorched at 35. A certain temperature difference is required. The ambient humidity is more than 60%, and most varieties can tolerate -8 low temperature (natural wintering, cloud tea is slightly not cold-resistant), and can generally overwinter naturally in the area south of the Huai River.

Camellia cultivation soil should be acidic and require good air permeability. Eliza is hairy and can usually be cultivated with peat, saprosa, laterite, humus, or a mixture of above. Camellia requires stronger light than rhododendrons, spring, autumn and winter can be shaded, and 50% shading can be used in summer.

It should be overwatered.

It can be planted outdoors on land for the winter.

The analysis is as follows: 1. Urban greening, camellia is planted next to the park road, usually in winter without anti-freezing measures, generally short-term frost and snow are difficult to freeze to death, unless the longer snow days may cause more serious frostbite or freeze to death, if it encounters a long period of snowy weather, plastic film can be used to cover the anti-freezing.

2. Most of the camellia is still relatively cold-resistant, can withstand -8 low temperatures, so it can be natural wintering, seedlings, weak seedlings, diseased plants and small trees under 4 years old, when the temperature is lower than 0 °C, they need to be frozen and warm, so as not to hurt the seedlings.

Here are some ways to keep warm in winter:

1. Balcony greenhouse: If there is no ground floor courtyard for camellia in the city, a small greenhouse can generally be set up on the balcony to let the camellia avoid the cold and winter. This small greenhouse is usually made of a 45-degree slope and a frame made of wooden strips, which are closed with plastic film on all sides.

2. Protect the water of flower buds: Camellia is in a dormant or semi-dormant state in winter, due to the low temperature, the evaporation of foliar water is less, and the water absorption of the root system decreases, so watering should not be more.

3. Fertilizer: Camellia in winter is in a state of weak physiological activity, manifested as the slow growth of leaf buds, flower buds, etc., so it does not need much nutrients, generally stored in the plant, and a small amount is absorbed from the soil, so improper fertilization before winter, too much fertilizer, too much fertilizer, too concentrated fertilizer, etc., will lead to the occurrence of bud fall, and the plant dies in severe cases.

Camellias can be planted outdoors in open fields for the winter.

Urban greening, there are camellia planted next to the park road, usually in winter without anti-freezing measures, generally short-term frost, snow is difficult to freeze to death, unless a longer snow day may cause more serious frostbite or freeze to death, if it encounters a long period of snow weather can be covered with plastic film to prevent freezing.

Note: Please forgive me for answering wrong, do not accept the correct answer, thank you.

My camellia is kept in pots, and the original soil balls I bought back seem to be sandy, and I added pine needles around them. It's been a year, I haven't applied fertilizer, I poured water when I remembered, and only sprayed potassium dihydrogen phosphate once or twice to promote flowering. Most of the buds are broken off.

It depends on where you plant, and it also depends on the variety of camellias.

I think you can build a shelf and plant some vines, such as ivy, so that you can enjoy the moon under the shelf in the summer evening, or some other plants that can bloom and be evergreen in all seasons, you can hang some pots on the shelf, and plant some words that can have a hanging effect, such as spider plant, which is evergreen in all seasons, and I personally think orchids are also good... There should be a sense of hierarchy, one high, one low, staggered. Plant some junzi orchids, bauhinia in other places, and you can bloom full of trees, camellias, yueji, jasmine, chrysanthemums in spring...

There are many common flowers that you can try to plant, so that you can see flowers all year round...

To build a garden on the top floor of the building, first consider the thickness of the planting soil and what plants to raise. In the case of soil layer not less than 80 cm, large-leaved boxwood, varieties of Yueji, wax plum blossom, spring flowers, etc. It can be evergreen in all seasons, and there are flowers to watch in all seasons.

Camellia likes acidic humus with higher and loose aerated mountain red (yellow) soil camellia are more suitable, and the pH value should be between 5 and between, camellia planting should be careful not to use alkaline soil or clay heavy soil as potted camellia substrate.

Soil Configuration Method:

Mountain soil (i.e. the ripening red loam soil of crops) 5 into, sawdust or fungus bran (i.e. the fungus residue of edible fungi) 4 into, cake fertilizer powder or the use of livestock manure and phosphate fertilizer powder accounted for 1 percent, the above three types are mixed, and then watered and bagged in order to mature, summer and autumn need more than 20 days, spring and winter to maintain more than 30 days, this can ensure that the soil is loose and aerated, fertilizer and water retention, can meet the needs of camellia growth and development.

This mainly depends on the local climatic conditions in Jiangxi and the roof microclimate.

Jiangxi's climate is extremely low, with an average temperature in January.

Summer temperature extremes range above 40 for many years.

At the same time, because the roof environment is more severe than the ground, the exposure time is long, the exposure area is large, the ground is hotter in summer, colder in winter, and windy in spring and autumn. So taking these conditions into account, as well as whether you plan to grow in protected areas or in the open air, will also make a difference in the choice of variety.

The next thing to do is to see how your house is structured, that is, how load-bearing the roof is, if the load-bearing is small, then you need to use lightweight materials instead of soil, such as perlite, vermiculite, etc.

Take open-air cultivation as an example.

The wind speed on the roof is high, so choose herbs and shrubs, and the height should not exceed meters.

In summer, the temperature is high, the sun is exposed to a long time, so it is necessary to choose light-loving plants that are resistant to sunlight.

In winter, the temperature is low and it should be cold-tolerant.

If the roof is not watered easily, then it should also be drought tolerant.

If you want to plant perennial plants, then the above conditions should be taken into account, this seems to be grapes are quite suitable and can be eaten, the varieties should be giants, hardy, creepers, pansies are also good, if it is an annual, then it is easy to do, winter does not consider, such as dwarf sunflowers, dwarf petunias, sunflowers, also called half-branched lotus, or biennial plants are grown after wintering, such as tulips.

If the load bearing is good, it is also very good to plant a bowl lotus (that is, a small variety of lotus), and make a tank with a diameter of more than 20cm, how beautiful it is when the lotus blooms. Water lilies are fine, but the flowers float on the surface of the water. Water lilies and bowl lilies are not the same variety, oh, the name is very similar.

You can read the specific cultivation details yourself, there are too many contents. For example, how to promote germination, how to care for seedlings, and how to control pests and diseases. Every plant is different. Buy this flower encyclopedia and everything.

Caryophyllus, half-branched lotus, cactus, gourd, pomegranate, sedum flowers, drought tolerant, strong light resistance, easy to maintain.

If you want to plant directly on the roof, you should first make a drainage impermeable layer, and then make a drainage layer, and it is best to lay nutrient soil.

In the roof greening, it is advisable to choose plants with not particularly developed root systems and good cold tolerance.

Such as: (woody) pomegranate, pine and cypress dwarf pile bonsai style.

Perennial herbs) Ophiopogon vulgaris, Horsetail Chinensis, Cinchona, Shanglu, Cypress Stone, White Axle Grass, Purple Leaf Sorrel, etc.

1 and 2 annual herbs) coleus grass, purslane, zinnia, kale, ground skin, grass jasmine, petunia, February orchid, etc.

Camellia sun-loving flowers need to increase light, and they are also prone to illness and need to be pruned and sprayed in time.

Camellia prefers acidic soil, the suitable temperature is 18 to 25 degrees, camellia is a semi-negative flower, the requirements for light and heat are not very high, but we still have to give it enough light to promote the formation of flower buds before the flower bud differentiation.

Camellia sinensis likes warm and humid climate, avoid too cold and too hot, and grow best when it is not higher than 25 during the day and not less than 16 at night. In summer, direct sunlight should be avoided, and after October and before May of the following year, you can fully receive sunlight. The potting soil is loose, breathable, well-drained, and slightly acidic with pH in between, which is the most suitable for cultivation.

Watering is an important part of cultivating potted camellia, and the principle of camellia watering is that it can be slightly wet during flowering and growth periods, and slightly dry during dormant periods; In summer and autumn, the temperature is hot, the rainfall is less, and the air is dry, so the potting soil should be kept moist and not dry, and the plants should be sprayed with leaf water to increase the air humidity and reduce the temperature, which is conducive to the growth of camellia. On rainy days, you should water less or no watering, and on rainy days, you should also prevent potting soil from watering.

Pay attention to reasonable fertilization. After the camellia is gone, in May and June, apply the diluted liquid of fully decomposed soybean cake twice a month, and apply the mixed fertilizer solution mainly phosphate fertilizer three times a month from July to before the flower color. Fertilization should be done in the evening on a sunny day.

Before fertilization, stop watering, so that the potting soil is slightly dry and absorbed, and the next morning after the "return water". 2 Do not fertilize in April.

Pay attention to bud thinning. In August, the buds that grow on the inner branches, overlapping branches, and crossed branches are plucked or cut off along with the branches. At the top of 1 branch, only 1 strong flower bud is left, and the rest is removed.

Camellia sinensis grows slowly and is repotted once every 3 years. Repotting can be carried out in March and early April, after flowering, when the spring shoots have not yet germinated. It can also be done in early to mid-June.

Hawthorn, pomegranate can, mulberry.

Copying trees is not suitable, and the root system of the previous two is still shallow! Bai roof greening, not only to choose plants with shallow roots, but also to be drought tolerant

Plants that are barren, light-tolerant, and wind-tolerant are generally shrubs and herbaceous plants, and there are few trees. You can choose the following plants for roof planting: black pine, podocarpus, melon seed boxwood, big-leaf boxwood, bird's-tongue boxwood, brocade boxwood, coral tree, palm, mosquito mother, yucca, gardenia, bamao, locust, bauhinia, crape myrtle, begonia, plum, birthday peach, magnolia, magnolia, geranium, rhododendron, peony, camellia, smile, yueji, orange, kumquat, jasmine, canna, dahlia, cycad, lily, lily, lily, cockscomb, wilt chrysanthemum, peach leaf coral, tung tree, bone, grape, wisteria, ivy, creeper, June snow, osmanthus, chrysanthemum, wheat winter, allium orchid, yellow xin, spring, velvet lawn, lotus, etc.

Since you don't know your geographic location, you need to determine the time and region to use the material. For roof gardens, there are also certain requirements for the cultivation medium, generally using lightweight materials, such as peat, coconut peat, perlite, vermiculite, sawdust, earthworm soil, etc., and some self-made media, such as humus and so on.

You use pots, isn't it okay, pomegranate trees are better, my family raises pomegranate trees, which bloom and bear fruit every year, which is very affordable.

Raising camellia outdoors, grasp the four keys, the leaves are green and shiny, and the flowers are big and bright.

Yes......But it is necessary to keep warm with a film. Note that the film should be propped up, not the mulch type. If the germination is attached, the germination rate will be reduced a lot. Of course, it would be best if you could choose another season.

Camellia usually needs to be watered with neutral or acidic surface water, watering to master the dry and wet, dry and then watered, watered to water thoroughly, but pay attention not to over-dry. Generally, at the end of spring, before budding, water should be appropriately withheld, so as to facilitate the transformation to reproductive growth, and the water should not be cut off before flowering. However, it should be noted that if it grows in the general living room, it is easy to die.

Usual fertilization can be used cooked cake (diameter 25-30cm pot) 10 grams pot; compound fertilizer 2 g pots; You can also use urea plus potassium dihydrogen phosphate, once every 10-20 days, and the above fertilizers should be used in rotation. If the yellowing of iron deficiency occurs in new shoots, ferrous sulfate can be poured once a week until it recovers. To prevent yellowing and root rot in the north, ferrous sulfate should be applied every 15-30 days.
