2. In addition, you must first determine what shape you want to make. Common shapes in the market are round, conical, multi-layer spherical and so on. When we have the general shape of Podocarpus, we should trim the extra branches and leaves outside the shape.
3. To fix the basic shape, it is necessary to prepare some small sticks and strong ropes, pull the branches in the direction of the shape diagram with sticks, and then tie the sticks and branches together with one end of the rope, and tie the other end to the main branch, thus changing the original growth direction of the branches.
4. When the branches are basically done, we need to find some small steel wires and copper wires for molding. Small steel wire or copper wire can be twisted into various types at will. The steel wire is tied to branches and leaves in the same way, and then gently twisted into patterns according to the modeling drawing.
5, bricks, this is also the key to making a beautiful bonsai with clear layering. For example, to make a double-layer bonsai, after the branches are fixed, the level on the branches is not clear. At this time, you can hang a small brick at two-thirds of the branches on the first floor, and the size of the brick can be decided according to your needs.
6, pruning, pruning the shape of bonsai leaves regularly, the branches will produce a certain fixed state after being fixed, and then the shape of bonsai will be presented through the shapes of leaves and branches.

cultivation techniques
1, planting
It is best to transplant in March-April in spring. Small seedlings need soil, and big seedlings need soil balls. In the hot summer season, it should be maintained in the shade. Pay attention to cold protection in winter.
2. Land
Fertile sand and slightly acidic soil with good drainage are needed. Potted soil can be composed of 5 parts garden soil, 2 parts coal soil and 3 parts coarse sand. Usually change the basin once every two years.
water
Keep the soil moist during the growing period. Water the soil when it is dry, and drench it in the morning and evening in midsummer to prevent the leaves from wilting. Keep the soil dry in winter.
Step 4 apply fertilizer
When changing pots, apply decomposed organic fertilizer as base fertilizer, and apply it thinly for several times in the growing season, and apply decomposed organic fertilizer in February-March and 9-165438+1October, and apply fertilizer to Panax notoginseng for 3-4 times.
prune
It is best to pick off the buds in time when flowering, so as not to consume nutrition. For the formed bonsai, we must pay attention to coring and pruning to prevent the branches and leaves from growing white, so as to maintain the original posture. Pruning and coring are best carried out in spring and autumn.
control of insect
1, pest
(1) The occurrence of pests and diseases of Podocarpus is rare, but attention should be paid to the prevention and control of red spider in hot and dry summer. Red spiders gather around the veins, leaf edges and branchlets of Podocarpus, forming mites, nymph mites and young mites to absorb juice. There are many pink-green spots on the front of the damaged leaves, and then they turn gray and lose their inherent luster. In severe cases, the whole leaf is gray.
(2) The control method is to spray some insecticides for treating red spider, such as pyridaben, hexythiazox, butazone, etc. , the high incidence of red spider (May-September), sprayed every 10 day 1 time.
2. Illness
The main diseases of Podocarpus are leaf spot and anthracnose. The control method is to spray 50% thiophanate-methyl wettable powder 500 times. Insects include scale insects, red spiders and giant salamander, and 40% omethoate EC 1500 times can be sprayed.
