However, in addition to the above mentioned, there are three points that flower friends need to pay attention to: 1 is pests, 2 is poisonous. The precautions for oleander cultivation are as follows:

How to raise oleander oleander cultivation methods and precautions

Oleander leaves such as willow bamboo, red flowers burning, better than peach blossoms, is a famous ornamental flowers. How to raise oleander? Let's take a look at the cultivation methods and precautions of oleander.

The cultivation method of oleander:

1. Turn over

Potted oleander two years to turn the pot for soil 1 time, pot bottom can put a little feather hoof angle type long-term fertilizer. During the growth period, liquid fertilizer can be applied 1 to 2 times according to the growth. Oleander pruning tolerance, germination force, aging plants can be combined in spring pot for soil renewal pruning, all branches from the base cut off, promote its germination of new branches rejuvenation. General plants should also be moderately pruned in spring to maintain plant symmetry and strong tree vigor.

II. Trimming

Through pruning, the branches are evenly distributed, the flowers are big and the trees are beautiful. The top branches of oleander have the characteristic of one-third, which can be pruned and shaped according to needs. If you need a three-pronged nine-top shape, you can cut off a part of the top of the three-pronged, and you can separate the nine-top. If you need nine top eighteen branches, you can leave six branches, cut off from the top leaf axils, you can produce eighteen branches. Pruning time should be after each flowering. In the north, oleander blossoms from April to October. The flowers that bloom should be removed in time to ensure nutrient concentration. It is generally divided into four times of pruning: one is after spring grain rain; the second is July and August; the third is October; and the fourth is winter pruning. If you need to flower indoors, move it indoors at about 15 ° C in the sun. Prune immediately after flowering, otherwise the flowers will be few and small, or even not flowering.

III. Root thinning

The capillary root of oleander grows faster. Three-year-old oleander, planted in a pot with a diameter of 20 cm, can grow roots before July of that year, forming a ball, hindering the penetration of water and fertilizer, affecting growth. If the roots are not thinned in time, wilting, falling leaves, death and so on will occur. The best time for thinning roots is from early August to late September. At this point the roots are dormant, and it is a good opportunity for thinning roots. Root thinning method: use a quick shovel to cut off the yellow hairy roots around; then use a three-pointed hook to thinning along the taproot. About half or one-third of the yellow hairy roots are thinned and replanted in pots. After thinning the roots, put them in the shade and irrigate them with water to keep the basin soil moist. Keep shade for about 14 days, then move to sunshine. Field planted oleander, in mid-September, should also be in the main stem around the yellow hairy roots cut. After root cutting, water and apply thin liquid fertilizer.

IV. Topdressing

Oleander is a kind of flower that likes fertilizer water, neutral or slightly acidic soil. Fertilization should be kept about 20% of the pot soil organic soil manure. If it is used for chicken manure, 15% is enough. Fertilization time: once before Qingming Festival and once after autumn equinox. Method: Dig a circular trench around the edge of the pot, apply fertilizer and cover with soil. After fertilization in Qingming, apply soybean cake water retting with water every ten days or so; after fertilization in autumn equinox, apply soybean cake water or peanut cake water or ten times chicken manure solution every ten days or so. Without the above fertilizer, it can be used to add water five to seven times more than the human urine decomposed for more than seven days, pour it along the edge of the basin, and then pour water thoroughly. Nitrogen fertilizer, the principle is thin, light, less, frequently, to prevent burning rotten roots.

V. Watering

Proper watering is the key to good oleander management. Improper watering in winter and summer can cause leaves, flowers and even death. Pouring once a day in spring and once a day in the morning and evening in summer keeps the water content of the basin soil about 50%. The leaves should be sprayed frequently. Too dry, easy to fall leaves, wither. Winter can be watered less, but the pot soil moisture should be maintained at about 40%. Foliage should be washed with clean water frequently dust. If it blooms in winter, the room temperature can be kept above 15℃; if it does not bloom in winter, the room temperature can be reduced to 7~9℃ and placed indoors in a bright place without sunlight. The oleander planted outdoors in the north needs to be wrapped with straw to prevent freezing and cold, and remove cold objects before and after Qingming. Although oleander is easy to manage, it cannot paralyze.

Notes on oleander cultivation:

Oleander likes plenty of light, warm and humid climate conditions. It is also slightly cold-resistant, and can be overwintered in warm temperate areas without defoliation. Summer potted plants should be watered frequently, sprayed, keep the pot soil and environment moist, but must not be wet for a long time. Oleander also has a characteristic, as long as there is a drought dehydration or water accumulation, the lower leaves of the plant will soon all yellow, fall off, so watering should be timely and appropriate. After early spring strong pruning, we should pay attention to Le water to prevent root infection and decay. Timely cut loose basin soil, flower wither after timely removal, summer occasional aphid and red spider harm, available general pesticide elimination.

5, pruning: oleander if not cut, the plant shape is too large, pretending to cluster cultivation to be on the branches or stems to be organized. Oleander germination force such as in the middle of the branch cut off, can be from its incision issued a majority of branchlets and affect the shape of the plant, so in principle must be cut off at the base of the branch when pruning.

6. Pests: Brown spot disease is an important disease on oleander. In the early stage of disease, spray 50% benomyl WP 1000 times or 25% carbendazim WP 600 times and 36% thiophanate-methyl suspension 500 times.
