What tips and tricks are there for growing southern flowers in the north?

1. Prepare suitable potting soil. Whether the potting soil is suitable or not is the foundation of successful flower growing. Southern varieties generally prefer acidic, well-drained soil substrates, such as rhododendrons, camellias, and clivias. A commonly used substrate mix ratio is: 4 parts pine needle soil, 3 parts peat, 2 parts garden soil. Such a substrate not only has good water retention, fertilizer retention, drainage and air permeability, but can also help buffer fertilizer effects, basically meeting the growth requirements of southern flowers.

2. Water scientifically. Watering too frequently and too much often causes yellow leaves, fewer flowers, and severe pests and diseases. When watering, it should vary according to the season, growth stage, variety, and potting soil. For example, water more during the growth period, water less during the flowering period, water less on rainy days, and water more during the dry season. The water quality should be slightly acidic and can be adjusted by adding ferrous sulfate.

3. Fertilize reasonably. People often think that the more frequently they fertilize, the better, so tea dregs, beer, rice water, and bean dregs are all poured into the flowerpot. Such undecomposed fertilizer is not beneficial to flowers at all and can easily burn the roots. When fertilizing, be sure to use fully decomposed fertilizer liquid and apply it after dilution. A small amount of chemical fertilizer can also be applied. The specific amount of fertilizer should be based on different plant varieties and different growth stages, and fertilizing should be done reasonably.

4. Adjust humidity and control temperature. Temperature and humidity are environmental factors restricting the normal growth of flowers and trees. Southern flowers generally prefer shade and coolness, and like humidity while avoiding dryness. In the north, artificial adjustment can be used, treating them differently according to variety. Spraying repeatedly with a sprayer has a good humidifying effect.

How to grow a money tree. What to do if the leaves of a money tree turn yellow

I believe many people place a money tree at home or in the office. First, the money tree has a very good symbolic meaning, and moreover, the money tree has a very graceful tree shape, with glossy green leaves all year round, making it a very attractive foliage plant. However, if not cared for properly, the money tree can also develop yellow leaves. Below is an introduction to how to grow a money tree and how to deal with yellowing leaves on a money tree.

How to grow a money tree

1. Choice of environment

The money tree is highly adaptable, likes light and tolerates shade, and grows well in full sun, partial sun, or shaded places. However, if grown in a dark place for a long time, its vitality will deteriorate. In early summer, it is best to provide 50% shade to avoid scorching leaf tips and leaf margins from intense sunlight.

For indoor ornamental cultivation, it should be placed in a spot with some scattered light, and it should not remain there continuously for more than 30 days. If leggy growth or deteriorating vitality occurs, it should gradually receive sunlight. Never expose it suddenly to strong light, to prevent it from dying from not adapting.

2. Choice of potting soil

Most money trees bought now come in soil provided by the seller. Gardeners do not need to change the soil immediately after buying one. Keep it growing first, and consider changing the soil later. If repotting, money tree pots generally use loose garden soil or peat soil, leaf mold, coarse sand, plus a small amount of compound fertilizer as base fertilizer and culture soil.

3. Watering a money tree

The root system of the money tree is very underdeveloped. Many gardeners' money trees die mostly because of root rot. Some gardeners may ask, how often exactly should a money tree be watered, and how much water at one time? It must be clearly stated here that conditions vary from place to place, and the pots and soil used also differ, so there is no fixed watering standard.

So how should it be watered? Generally speaking, watering a money tree once a month is not too little. Also, here is a little tip for gardeners: plants will not die quickly from lack of water and will recover quickly after watering, but if they are waterlogged, they basically cannot be saved. Usually, a money tree can be sprayed with water more often and watered less.

3. Fertilizing a money tree

Under normal circumstances, if the soil is fertile enough, no fertilizing is needed. If it has been grown for a long time, consider giving light fertilizer. Never use concentrated fertilizer. For fertilizing, some common foliage fertilizers can be used. Remember to use light fertilizer.

Note: Generally speaking, money trees have been topped, so every spring gardeners can also prune them appropriately. This can make them more attractive and also promote the growth of new branches.

4. Watch for pests and diseases

If the stem surface is found to be black or black thread-like fibers are exposed, it is stem rot causing the money tree's stem to rot. In the early stage of the disease, spray a 1000-fold solution of 50% water-soluble powder of Fungus Killer, once every 10 days, for 2-3 consecutive treatments.

For anthracnose, spray 50% chlorothalonil wettable powder at 800 times or 50% carbendazim at 600 times for prevention and control, once every 7-10 days. For cabbage caterpillars, inchworms, and red spiders, regularly spray 40% omethoate at 800 times or 50% dichlorvos at 1000 times, once every 7 days, spraying 2-3 times in succession.

What to do if the leaves of a money tree turn yellow

1. Overwatering

Long-term excessive moisture in the potting soil causes a lack of oxygen in the soil, makes some fibrous roots rot, hinders normal respiration and the absorption of water and nutrients, and causes leaves to turn yellow and fall off. After being affected, the young leaves first turn pale yellow, and then the old leaves gradually turn yellow as well. Watering should be controlled immediately, fertilizing stopped, and the soil often loosened to improve aeration.

2. Drought and dehydration

Missing watering or long-term half-watering (that is, wet on top and dry below) affects nutrient absorption and can also easily cause the leaves to become dull and lusterless, and the leaves to wilt and droop. First the lower old leaves age, and gradually dry up and fall off from bottom to top. At this time, a small amount of water is needed along with misting, so that they gradually recover and then return to normal watering.

3. Long-term lack of fertilizer

If nitrogen fertilizer has not been applied for a long time or the pot and soil have not been changed, the soil lacks nutrients such as nitrogen, resulting in weak branches and leaves and thin, yellow leaves. The pot should be changed in time, replaced with new loose and fertile culture soil, and gradually given dilute decomposed liquid fertilizer or compound flower fertilizer.

4. Excessive fertilizing

If too much fertilizer is applied, new leaves will become thick and fleshy, and mostly uneven. Old leaves will dry at the tips, scorch yellow, and fall off. Fertilizing should be stopped immediately, watering increased so that fertilizer flows out from the drainage holes at the bottom of the pot, or the pot should be changed immediately, the soil ball rinsed with water, and then replanted into the pot.

5. Hot and high temperatures

In summer, if flowers that prefer coolness (such as cyclamen, fuchsia, and begonia) are placed in a high-temperature spot and exposed directly to strong light, the tips and margins of young leaves can easily scorch, or the leaves can turn yellow and fall off. They need to be moved promptly to a cool, well-ventilated place.

6. Excessive shading

If sun-loving flowers are kept for a long time in a shaded place or a place with insufficient light, the branches and leaves will turn yellow.

7. Soil and water too alkaline

Most areas in the north have soil and water with relatively high salinity and alkalinity. When planting acid-loving flowers such as rhododendrons, camellias, banana shrubs, gardenias, orchids, white michelia, and osmanthus, because the soil lacks absorbable soluble iron and other elements, the leaves will gradually turn yellow. When planting, choose acidic soil, and during the growth period frequently water with alum fertilizer water.

8. Too dense and poorly ventilated

If too much nitrogen fertilizer is applied, the branches and leaves grow too luxuriantly. Combined with a long period without pruning, the inner branches and leaves lack light, which can easily cause leaves to turn yellow and fall off. Fertilize reasonably and strengthen pruning to provide ventilation and light.

9. Dry air

When indoor air is too dry, some flowers that like humid environments, such as spider plants and orchids, often show dry leaf tips or scorched leaf margins. Attention should be paid to measures such as misting and covering with plastic film to increase air humidity.

10. Improper temperature

If the indoor temperature is too low in winter, flowers that like high temperatures are often susceptible to cold damage, causing leaves to turn yellow, and in severe cases to wither and die. If the indoor temperature is too high, the plant's transpiration is excessive, and the roots cannot supply enough water and nutrients, which can also cause leaves to turn yellow. Please pay attention to adjusting the room temperature in time.

11. Soil too acidic

Southern red soil is acidic, and elements such as magnesium are easily lost. When planting trees and flowers that tolerate alkalinity or prefer slightly alkaline soil, such as oleander, boxwood, and winter jasmine, yellowing between the veins of old leaves often occurs. Calcium magnesium phosphate fertilizer can be applied or a magnesium sulfate solution sprayed.

12. Damage from pests and diseases

Leaf spot disease caused by infection with fungi and other pathogens can easily cause local necrosis of leaves, with yellow spots or patches appearing, and in severe cases the whole leaf withers, turns yellow, and falls off. After infection by mosaic virus, yellow-green mottled patches appear on the leaves. When damaged by scale insects, red spiders, and others, the leaves can also become partially yellow and withered, or even the whole leaf wilts, turns yellow, and falls off. In all cases, pesticide spraying should be carried out promptly for prevention and control.

13. Strong stimulation

When preventing and controlling pests and diseases, using pesticide concentrations that are too high, or being polluted by toxic gases in the air, or suddenly watering with cold water when the temperature is high, can all easily cause the leaf tips or parts of the leaf surface to turn yellow and scorch, or even kill the whole plant.

Therefore, attention should be paid to the reasonable use of pesticides and to finding ways to eliminate sources of air pollution. In midsummer, avoid watering flowers with cold water around noon. Finally, it should also be mentioned that yellow leaves on potted flowers are sometimes caused by one reason, but are often the result of multiple factors. A correct diagnosis should be made so that the right remedy can be applied.
