Attention should be paid to the details of the raised rose from the pot to the explosion.

Rose, because more flowers and gorgeous, everyone likes to raise. However, looking at other people's rose, from seedlings to bursting pots, it feels like a very simple matter. In fact, raising roses, from the upper basin to the bursting basin, we have to "pay attention" to many details.

1. The season of the upper basin

Rose pot time, for grafting and cutting seedlings in April pot, 1~2 years old seedlings and large seedlings, must be in dormancy to germination (November ~ January) pot or set pot.

2. Selection of seedlings

Rose raised good, not as good as the choice. Flower friends should choose seedlings with strong development, vigorous invasion, thick branches and no diseases and insect pests. In this way, it is easy to raise them.

3. Preparation of basin soil

Water drainage, ventilation, water conservation, fertilizer conservation and various nutrients should be paid attention to in pot soil preparation of rose. The pot soil formula is: (1) garden soil 5 parts, rotten leaf soil 2 parts, decomposed cow dung 2 parts, sandy soil 1 part, and then add a small amount of vegetable cake, bone meal, potassium sulfate, etc. (2) Clay 1 part, sand 1 part, composted 1 part, add proper amount of vegetable cake, bone meal and potassium sulfate.

4. Key points of fertilization

For the maintenance of roses, especially potted roses, in addition to applying about 25 grams of horseshoe chips as base fertilizer in spring, along with the growth of rose leaves and the opening of flowers, the organic liquid fertilizer rich in nitrogen, phosphorus and potassium for roses should be applied once every 7 days in the vigorous growth stage, diluted 500 times, and the roots can be irrigated directly.

In rainy season, it is inconvenient to apply liquid fertilizer. At this time, flower friends had better apply chicken manure granular organic fertilizer, the dosage is about 5 grams per pot, sprinkle it on the surface of the pot far away from the stem of the plant, and then cover the soil. Topdressing should be stopped in winter.

5. Select basin and upper basin

For rose selection pots, miniature rose cuttings can be used for 5-7 cm diameter pots, generally rose cuttings with a diameter of about 14 cm pots, grafted seedlings with 20-24 cm pots. 1 - 2 years old seedlings with 26-30 cm pots.

For rose cuttings and grafted seedlings on the pot, you can do not have to trim the roots, but must be too tender top shoots and buds trimmed off. More than a year of field seedlings moved to the pot, must be intensive pruning, cut off too long thick roots, retain fibrous roots, leave 2~3 strong trunk, each trunk leave 2~3 strong buds, the rest are all cut off, and then on the pot.
