How do you cut down on Australian trees?

Australian fir is a very good bonsai plant, and it is also suitable for breeding at home, so how to prune it? What about the rotten roots of Australian fir?

How to prune Australian fir:

1. Prune according to your habits

First of all, let's talk about the growth habits of Australian fir, because no matter how we trim it, we have to make sure it can grow and develop healthily! The most suitable temperature for Australian fir growth is 10 degrees Celsius to 25 degrees Celsius, and make sure the temperature is at least above 5 degrees Celsius. No matter which season, a certain amount of light every day is essential, but also pay attention to the basin soil to be moist, the air around the plant should also maintain a certain degree of moisture.

2. Pruning methods

1. Cut short. This pruning method is to cut off part of the overgrown branches of Australian fir in order to stimulate its lateral buds to sprout quickly and grow new branches to improve the visual effect of Australian fir viewing.

two。 Thinning and cutting. This pruning method is to cut off the branches of the Australian fir from the bifurcations, which can make the branches more evenly distributed, increase ventilation and light transmittance, and is conducive to the rapid growth of the internal branches of the Australian fir. This method is mainly to cut off dry branches and over-dense branches.

3. Tiller removal. This pruning method is to remove twigs or root tillers from the bottom of the Australian fir trunk or near the mountain pass, so as to prevent these tillers from affecting the overall appearance.

Finally, I would like to remind you that when pruning, you need to pay attention to the sharp and smooth scissors, and the scissors should be at an oblique angle of 45 degrees between the scissors and the branches, so that the cut will be smaller, which is conducive to the healing of the cut. New buds can grow quickly. If you want to inhibit the growth of too exuberant branches, you can choose the small buds of Australian fir as a cut, which can promote the growth of strong buds!

What about the rotten roots of Australian fir:

1. Timely ventilation

If it has rotten roots, be sure to put it in a good ventilated position, so that it will not be so wet, and keep the cultivation environment dry, because if the bottom of the basin is too wet, it will make the roots of Australian fir easy to produce stagnant water. keep it in a particularly moist state for a long time, exceeding its need for water, and it's easy to make the roots unable to breathe. And good ventilation can keep it dry in time, so it will not be so easy to produce rotten roots, we must pay special attention to ventilation.

2. Disinfect the flowerpot

When we choose to plant Australian fir, we should choose good soil, and it is best to use soil with good drainage to ensure the demand of roots. Then disinfect the flowerpot properly, so that the root is not easily infected by bacteria. When it rots the root, disinfecting the flowerpot again can also eliminate some bacteria in the root, so that the root will not continue to infect. The phenomenon of rotting roots will gradually improve.

3. Drug control in the early stage of the disease.

We can spray wettable special powder on the ground every 10 days or so in the early stage of the disease of Australian fir, and the dosage must be adjusted in accordance with the requirements. The underground part is diluted with 70% of other chemicals and watered for 2 to 3 times, so that its root rot can be controlled without getting more serious. kill all the bacteria in the early stages of the disease. The survival rate will also be very high.

4. Retransplant and planting

When there is a rotten root, we can remove the sprained root and the rotten root, and then spray it on the wound with a special spray, dry it and plant it again, which will survive well.

5. Drug spraying treatment

If the rotting bacteria in the rotting roots of Cunninghamia lanceolata are more active and difficult to control, then we can properly spray with some drugs to completely eliminate it.

All right, guys, you all know how the Australian sequoia was built.

Generally from July to August, the newly collected seeds will first break the seed coat in order to promote germination, otherwise leaving the soil for a long time will easily cause the seeds to rot, and then sow the treated seeds in the sand bed, covering about 1.5 cm of fine sand. Under the condition of 25-28 ℃ and a certain humidity, it can germinate after about 2-3 weeks, and it can be planted immediately after germination.

2. When cutting, if you choose the main axis or overgrown branches as cuttings, it is easy to cause incorrect crown shape of the plant, which can only grow horizontally and affect the ornamental value. Cut the first 2-3 nodes of robust branches that are easy to root as cuttings, remove some leaves, soak them in clean water overnight, and then insert them into a sand bed based on coarse sand or vermiculite. Keeping the temperature of 20-25 ℃ and high air humidity, it can take root after about 3 months.

2. In the process of growth, in order to avoid tilting the trunk to one side, it is appropriate to turn the pot once a half month to let the plant receive light evenly. In addition, the trunk of young trees is fragile and easy to bend, so it is appropriate to set up pillars to fix the trunk from the time of young trees. In order to prevent the plant from growing too tall, the pot should be changed every 2-3 years after the spring is warm. At ordinary times, we should pay attention to protect the lateral branches so as not to be damaged and affect the plant shape.

3. Under normal circumstances, Australian fir does not need to be pruned to allow it to grow naturally. The suitable temperature for growth is 10-25 ℃, and the overwintering temperature is above 5 ℃.
