Tip 2: When you visit heel in or buy 128 plug seedlings in a sunny place for the first time, you usually put a small pot of about 12 cm on the pot. After the heel is planted in the basin, ensure sufficient sunshine and water it alternately. When the branches are full of heels in the pot, they can be planted. Choose 1 flowerpot with a diameter of at least 25 cm for planting, or plant 2 flowerpots in a flowerpot with a length of 40 cm to ensure the growth space. Dwarf cows need sunshine all their lives. Without sunshine, plants will grow white and spend less. In Jiangsu, Zhejiang and Shanghai, short-legged cattle can spend the winter in the open air as long as they are not frozen by rain and snow. If there is a sun room, try not to get too hot, or the branches will blossom ahead of time before they grow luxuriantly.
The third secret: the second factor of topping a dwarf cow is topping. After removing the apical dominance, the germination of lateral branches was promoted. The more lateral branches, the more main flowering forces. The first coring and topping are usually carried out when the seedlings have 6 true leaves. Thereafter, when the lateral branches grow to 6 leaves, topping is performed once, and 2 leaves are pinched off, leaving 4 leaves, which is referred to as "pinching 2 and leaving 4". At the beginning of March, the last pruning was carried out, and a pot of hanging cattle with compact branches took shape.
Tip 4: High phosphorus dwarf cattle are flowers that need fertilizer very much. After planting, the growth liquid fertilizer was poured every 7- 10 days until the end of February. When planting, long-acting fertilizers such as chicken manure fertilizer or slow-release fertilizer are added; From the beginning of March to the whole flowering period, flower liquid fertilizer can be irrigated 1-2 times a week.
Tip 5: Petunia hybrida is a flower that grows very fast. Of course, growing fast means dying fast, and the only way to keep it blooming wildly is to chop it hard. The vigorous growth period of dwarf cattle is June, July, August and September, and it is cut once every three weeks, and it blooms again about 10 days after strong cutting.
65438+1before the cold wave strikes on October 20, it will be cut 3-4 times, mainly in July, August and September. Dwarf cattle can be used as biennial herbs if they are continuously cut and managed.
The flowering period of hanging Petunia usually begins in mid-April and lasts until the end of June. After each heavy rain, the rotten branches and leaves should be cleaned up. Prune the whole plant type at the end of June, leaving the main branch 15-20 cm, and enter the second flowering stage in about 20 days. The second flowering period can last until September. In case of strong wind and heavy rain, the sunshine may be shortened and the autumn will basically recover. Petunia can bloom for two years. It is suggested that replanting should be carried out after the second summer to ensure the plant's health.
The growth cycle of dwarf cattle is the same as that of many products. The first is the introduction period, during which the bought (or self-sown) seedlings are followed up, pitted and reshaped, and a large number of flower buds begin to propagate; Then there is the growth period, during which flowers begin to bloom and many buds come out to continue to open; Then there is the mature period, during which the whole pot of flowers is full and every bud is in full bloom; Finally, the economic recession. In this period, there are more failed flowers than growing buds. The longer plants grow, the more dispersed they become. Although it is still prosperous on the surface, it has existed in name only. In this period, we should not hesitate to cut short Niu Qiang. The harder we cut, the better the flowers will bloom. If we wait until this period is completely over, until the flowers are completely ruined and the plants turn yellow, the dwarf cow is likely to die.
