Don't apply too much fertilizer, but a small amount should be applied frequently, and it is advisable to irrigate the basin soil with dilute fertilizer solution. Lighting needs sufficient environment and should not be kept in the shade for a long time. It also needs proper ventilation to grow well. In winter, sufficient light must be given and ventilation should be carried out according to the ambient temperature. It is forbidden to blow air conditioning in winter.
Maintenance methods of hibiscus.
Fusang originated in China and distributed in Guangdong, Fujian, Guangxi, Yunnan and other provinces. I like warm, humid and sunny environment, and I am not tolerant of drought and frost. Potted plants must be planted in the north of the Yangtze River and moved indoors in winter. Hibiscus has a long flowering period, and bloom can be found all year round at the temperature of 15℃-20℃. Fusang has strong resilience and extensive management, and does not need special management. As long as you master the following methods, you can grow up healthily. Change pots and trim potted plants with loose and fertile sandy loam. Before moving out in early spring and April every year, we have to change pots. There are three things to do when changing pots:
First of all, put on a new cultural soil.
The second is to cut off some fibrous roots that are too dense and curly.
The third is to apply plantar fertilizer and slightly add phosphate fertilizer to the pelvic floor.
In order to maintain a beautiful tree shape and a large number of flowers, according to the characteristics of strong germination ability of hibiscus, pruning and shaping can be carried out before and after leaving the house in early spring. Except for the 23 buds at the base, all branches were cut off at the upper part. Pruning can promote the new branches to grow more vigorously and the plant shape is beautiful. Water and fertilizer should be properly controlled after pruning, because the consumption of aboveground parts is reduced.
After leaving home, the management of hibiscus is an active tree species. At the beginning of May, we should move outdoors and put it in a sunny place. At this time, it is also the growing season of hibiscus. It is necessary to strengthen the management of fertilizing water, loosening soil and pulling weeds. Apply dilute liquid fertilizer every 7- 10 days, and water it according to the wet and dry conditions of the basin soil. Too dry or too wet will affect flowering. Attention should be paid to the maintenance and management of hibiscus after autumn, and less fertilization should be paid in the later period to avoid sprouting autumn shoots. Autumn bamboo shoots are tender and weak in cold resistance, and will be frozen when the weather is cold. When entering the house in time, Fusang is not frost-tolerant. After the first frost, it must be moved indoors to keep warm before beginning of winter. The overwintering temperature shall not be lower than 5℃ to avoid freezing injury; Not higher than 15℃, so as not to affect dormancy. Poor dormancy leads to poor growth and flowering in the following year. All furniture rooms with good heat preservation conditions facing south can survive the winter, and can be covered with paper or plastic film for heat preservation when the weather is cold. Move the house for the first time every day, open the window for ventilation, pay attention to the dry and wet changes of the basin soil, and water it properly. In the coldest days, watering can prevent freezing injury, but fertilization should be stopped.
Pests and Diseases Control There are few pests and diseases in hibiscus, and sometimes aphids and scale insects occur due to poor ventilation and lighting. Kill or spray dimethoate immediately after discovery.
Maintenance method of desert pineapple
When it comes to how to raise desert pineapples, it is necessary for us to know about desert pineapples. Generally speaking, we grow desert pineapples from Dyckia or Hechtia. Dyckias and Hechtias are two genera of terrestrial pineapple, which can be used as potted plants and garden plants, especially in some warm and dry regions.
Dyckias originated in South America, Hechtias mainly originated in Mexico (others came from some Central American countries). The two genera of pineapple look like non-fleshy agave (Hechtia is called pseudo-agave), and they are both rosettes with hard and prickly leaves, so it is often difficult to distinguish them. Both plants are sucking plants, and they tend to be sunny and relatively dry. In fact, almost all Hechtias have white flowers, while the colors of Dyckias are mainly bright orange and yellow in different degrees. Dyckias are not a plant (they grow year after year), and Hechtia will die after flowering. Of all the bromeliads, Dyckias is the most hardy (they can resist the low temperature of 20 degrees Fahrenheit, or even lower in some cases). ), and Hechtias is one of the least cold-resistant pineapples, and it is difficult to resist the short-term frost of more than 20 degrees Fahrenheit.
The planting medium of Dykcia(Hechtia) belongs to pineapple, so it is best to choose humus soil with good drainage and appropriate amount of gravel. A mixture of hard bark, volcanic rocks, stones, perlite and sand can also be used as a medium. A small amount of water can be used in spring and autumn, and the soil should be kept dry in the low temperature environment in winter to prevent freezing injury. If necessary, you can use semi-cooked fertilizer once a month.
Dyckia(Hechtia) can be planted in indoor and outdoor environment: on the sunny terrace, potted or hung pineapples planted with Dyckia have strong ornamental value. Pineapples belonging to the genus Dyckia(Hechtia) can also be planted as indoor ornamental plants in sunny or well-lit rooms, and compared with other pineapples, pineapples belonging to the genus Dyckia(Hechtia) have lower humidity requirements. Dyckia can also grow well in dry places, such as rocks or cactus gardens.
If you need to plant Dyckia pineapples in wet and rainy areas, you can plant them in well-drained pots and the plants will grow equally well. Half-day or all-day outdoor lighting can bring dazzling colors to Dyckia's leaves. Many Dyckia can tolerate frost above 30 degrees Fahrenheit (many Hechtia can tolerate frost above 16 degrees Fahrenheit), but most of them like relatively mild temperatures, so it is best to avoid frost as much as possible.
Maintenance method of goldfinch
Goldfinch likes light and bears drought, so it should be placed in a sunny and ventilated place. It is cold-resistant in winter, and it can be wintered outdoors to the south of the Yellow River. It is best to bury the basin in the soil.
Watering: master the principle of not watering, but watering thoroughly. Especially in the flowering period, we should pay attention to keeping the soil moist, which can prolong its flowering period.
Fertilization: base fertilizer can be applied once in winter dormancy period, and water and fertilizer can be applied once before flowering in spring to prolong flowering period. Top dressing again after flowering to promote the growth of branches and leaves. Usually, it is enough to apply a thin amount of fat water.
Pruning: After defoliation in winter, you can cut off all kinds of branches that affect the tree shape. After flowering in spring, cut off the flowering branches to promote the growth of new flower branches. In the vigorous growth period, long branches can be pruned at any time, and the core can be picked appropriately to keep the tree beautiful.
Turn the pot: turn the pot every 2 ~ 3 years, and the period is suitable for early spring. About 1B2 of old soil can be removed when turning the pot, and the excessively long root system can be appropriately shortened. Can also be combined with pot turnover for root lifting modeling.
It is mainly for flower viewing, and the flowering period from May to June is the best viewing period. You can also see trees of various shapes at ordinary times. Flowers in full bloom on the tree, such as goldfinches, are full of golden eagles and swaying in the breeze, which is very pleasing to the eye.
