What should I pay attention to when planting iron trees in winter?

Ventilation but not to freeze it.

1. Precautions. Iron trees grow like a warm environment, iron trees are not tolerant to cold, so in winter, we should pay attention to cold and keep warm, to prevent frost damage. In addition to paying attention to shade, our potted iron trees also need to spray their leaves at least once a week to prevent the occurrence of yellow leaves caused by high temperatures.

2. The requirements for the soil of iron tree breeding are not obvious, but if it grows in slightly acidic soil, the soil should be sandy loam, or some loose, drained and humus-rich soil. Therefore, we can use a portion of humus + garden soil + river sand. Secondly, you can also use garden soil + peat soil + river sand or saprophytic leaves.

These soils are ideal for growing iron trees. It is rich in nutrients, has good drainage properties, and can promote close growth and more lush.

1. Don't expose to the sun after watering, too strong light will increase its consumption burden, let it consume water and nutrients excessively, and there are not many new roots to absorb water and nutrients, and the leaves under it will speed up the drooping, accelerate the yellowing, and finally slow the seedlings will fail, and you need to put it in a place where you can see a little scattered light.

2. Ensure good ventilation, and it is impossible to rot roots after ventilation. This slow spike to raise for a period of time, about a week or so, you will find that the leaves under it will gradually and completely wither and yellow, and then cut off directly, the upper leaves will slowly recover the spirit, and the root system under the bottom will gradually grow, watch the leaves recover the spirit, do not continue to yellow the oak slag on it.

Soil: fertile, sandy, slightly acidic, with good permeability.

Moisture: drought tolerant, avoid stagnant water.

Light: light-loving, slightly tolerant of semi-shade.

Temperature: Prefer warm, not very cold-tolerant, when the temperature is lower than 0 degrees, it should be moved to 5 to 10 degrees indoor wintering.

Base fertilizer: organic fertilizer-based, with the application of P, K, FE (rust iron filings, 2-3 pieces of horseshoe flakes fertilizer topdressing: summer growth period, apply thin rotten cake fertilizer water, 1-2 times a month, such as adding "black alum water" (ferrous sulfate) in the top dressing, the leaf color can be thick green and bright.

Stop topdressing in autumn.

Winter fertilizer: apply organic fertilizer (5kg plant) and P and K fertilizer before winter.

Note: Newly planted needs to be shaded for half a month, and the soil should not be too wet to avoid root rot.

In high temperature, dryness, poor ventilation, the leaves are susceptible to scale insects, control can be removed with a brush brush or timely sprayed with 50 dimethoate emulsion or 50 monocrotophos or 80 dichlorvos emulsifiable concentrate 1000 times.

When the high temperature and air humidity are high, white spot disease and coal stain disease are prone to occur, and carbendazim 50 wettable powder or Tobuzin 70 wettable powder can be mixed with water 1000 times to spray the diseased plant in the early morning. [

Iron tree likes sunlight, in spring and autumn, the seedling stage is best placed in direct sunlight (but not exposed) maintenance

Potted iron trees have short leaves, stout, neat, dark green leaves, and bright and moist leaves for their high ornamental value. The key to achieving this effect lies in the management of the dormant period in winter and the growth period of new leaves in early spring. Repotting young iron trees are best to change pots once a year, adult iron trees are repotted once every 2-3 years, the time is in the dormant period (before the beginning of winter - before the rain) is better, and the small pots are generally replaced with large pots.

When repotting, pour the iron tree and the soil mass out of the old pot, remove some of the old soil and old roots in the lower part of the soil mass, and try not to hurt the mycorrhizae on the soil surface. Repot with nutrient soil, fix the iron tree, and water it thoroughly. The newly added nutrient soil must be loose and fertile, permeable and breathable, and can be prepared with 1 part humus, 1 part coal ash, a small amount of fermented cake fertilizer and a little iron filings.

Pruning Combined with repotting and pruning, cut off 1-2 rounds of old leaves in the lower part of the iron tree; It can also be properly pruned before the new leaves grow out of the iron tree 1-2 rounds of old (yellowing) leaves to reduce nutrient consumption and kill pests and diseases. If the leaves are uneven (or have no ornamental value), all the leaves can be cut off (shaved heads) to allow the iron tree to grow new leaves; When pruning, stick to the dry pruning, leaving no petiole piles. The most common insect pest of iron trees is scale insects, which are commonly found on the lower old leaves.

Therefore, it is necessary to prune in time to prevent pests and diseases from hiding. Before the new leaves grow in spring, the whole plant can be sprayed with 800-1000 times of 80% dichlorvos emulsion, once in 7-10 days, and sprayed 3 times in a row. Control light and water fertilizer In early spring, place the iron tree in a sunny place, and when the top of the iron tree is fluffy and new leaves are about to grow, stop watering, fertilizing, and ensure that the sun is sufficient and sheltered from the rain.

When the leaves grow and the petiole is not exposed, it can still not be watered (a small amount of water can be watered when it is too dry), and it can be watered until the leaves are stretched and fully developed. Fertilization is better with well-rotted cake fertilizer and compound fertilizer, diluted with water and applied once every 10-15 days, and once a month with alum fertilizer water. The leaves grown in this way are thick and dark green, and the ornamental value is high.

In winter, the temperature is not lower than 2 to safely overwinter, and adult trees must maintain a temperature of more than 12 for the winter to bloom normally.

In winter, when the temperature is below 0 degrees, it should be moved indoors for wintering. Keep the room humid at 5-10 degrees. In April of the following year, they will be released from the room and repotted once every 2 or 3 years.

No fertilization, watering gradually decreases, and watering after drying.

Normally, it won't die, and the best way is to wrap some straw around it, and come to winter, and the leaves will grow again the next year.
