Do you know how long it takes from seed to flowering? What month does it open? How to raise it? According to Rosaceae data, the rose florescence is from April to May. It is explained here that the so-called "rose" is the "modern rose" bred by the cross between rose, rose and rose. Using artificial control, there are flowers every year.

How long does it take from rose seed to flowering?

It takes about 40 days for rose seeds to bloom in summer and 60 days in winter. Pruning requires about 20 days of rooting in summer and 40 days in winter.

How do you grow roses?

1. Potted plants

1. Culture environment

Rose Xiyang, indoor culture is also placed in the sunny balcony maintenance, potted rose soil requires loose, fertile, good drainage. Pay attention to the poor growth and flowering of roses in clay loam. It should be planted in a well-ventilated place far away from the wall to prevent sunlight reflection, burning buds and affecting flowering.

2. Watering roses

Potted roses should not be watered too much. Roses are drought-tolerant and waterlogged plants, and strictly adhere to the principle of "no dry, no watering, watering thoroughly". If you water roses frequently (especially taboo on rainy days with high humidity and low evaporation), rotten roots and dead plants are easy to occur.

3. Fertilization of roses

Potted roses should be treated with light fertilizer, avoid thick fertilizer (especially chemical fertilizer) will lead to local root rot and death. According to the size of the plant and the basin, 20-40 grains of compound fertilizer (or nitrogenous fertilizer) are applied evenly under 1 inch of soil at the edge of the basin every 1-1.5 months, or light water and fertilizer such as fully fermented rice panning water are irrigated once or twice a month. As long as the green leaves and flowers grow well, there is no need to apply fertilizer.

4. Daily pruning

Usually do not need pruning, the old plant has been trimmed dense branches, withered branches, disease and insect branches can be. Roses bloom, pick as they bloom or fail, and blossom again after picking, otherwise they will only bloom once. In order for roses to grow well and blossom more, pruning is very important. In general, when overwintering, all branches should be cut off about 10 centimeters above the ground to make it through the winter smoothly.

5. Disease and pest control

Potted roses, the main pests are green insects and shell insects, green insects are easy to treat, once the outbreak of shell insects, more difficult to control, will lead to the whole plant infected, and lead to diseases, so the control of shell insects is the focus of domestic roses. To prevent and control shell insects, it is necessary to put the roses in a place with good ventilation and good light, cut off the branches with many roses, and retain several main branches to ventilate the interior. Keep the basin soil moist, but don't accumulate water. When there are white spots on the rose branches, scrape them off with bamboo slices in time. If it is more serious, cut off the whole branch or even all the branches directly, and spray the medicine to kill shell insects. Roses are not afraid of pruning, and the following will introduce the pruning of roses.

6. Points for attention

Watering, afraid of stagnant water, timely drainage and waterlogging prevention in rainy season

Potted soil, fertile and well drained

Sunshine, plenty of sunshine, sunscreen in summer

Second, water planting roses

1. End smashing method:

Smash the end of the pedicel of the whole bunch of roses with a hammer, about an inch, so that the roses can absorb more water, absorb enough water, and the roses can last longer.

2. Fresh flower preservative:

Adding appropriate amount of chemicals to the flower arrangement solution can prolong the fresh-keeping time by inhibiting the flower branches. If the antistaling agent is not available for the time being, it can be preservative with potassium permanganate 1/4000 aqueous solution, or a simple antistaling agent prepared with aspirin 1/3000 aqueous solution, which can also make it blossom.

3. Scalding method:

Soak the base of the flower branch in boiling water and pick it up after ten seconds (fragile and delicate flowers, which can only be soaked for one or two seconds). This can infarct the incision, prevent the tissue of flower branches from overflowing, and have a better effect on herbaceous flowers.

4. Brine or sugar water culture:

Add a little salt or sugar to the water for growing flowers, or crush the cut when the flower branches are just cut off, and wipe it with salt, the effect is better than blanching. Sugar can make flowers bright and lasting. However, flowers with buds should not be soaked in salt water, otherwise it will be very difficult for the flowers to open.

5. Liquid immersion method:

Before inserting the rose branch into the vase, soak the end of the rose branch in a used waste developer for half an hour. The flower branch treated in this way can prolong the florescence.

6. Tea method:

Rootless flowers inserted in a vase are easy to wither. In general, the flowering period of clear water is only three or four days before gradually withering. If you use tea (you can also use freshly brewed tea, but only after the tea has completely cooled) instead of clear water, you can delay the withering time of flower arrangement, and the tea should be thicker. If you use tea to arrange flowers, the flowers will not wither within 7 days, and the flowers will be bright and fragrant.

7. First aid method:

When the rose hangs its head, you can cut off a small section at the end of the flower branch, and then put it in a container full of cold water, leaving only the flower head exposed on the surface of the water. After 1-2 hours, the flower branch will wake up. Grass and woody flowers are applicable.

8. Beer law:

Put a little beer in a bottle of roses, or put the flowers in a beer bottle filled with foam, and add the right amount of water, and you will find that the shelf life of these flowers has been extended. This is because beer contains ethanol, which can disinfect and preserve flower branch incisions, as well as sugar and other nutrients, which can provide nutrients for branches and leaves.

9. Antistaling agent method:

It is better to prolong the florescence by using 1/3000 aspirin solution or 1/2000 potassium permanganate solution to raise flowers.

10. Dip in water to prune:

After taking the roses home, soak the base of the flower branches in water as soon as possible, then cut some of them obliquely in the water with scissors, and then immediately insert them into the vase and raise them. Flower-growing water is also fastidious, it is best to use natural water, do not use mineral water, tap water, preferably well water, river water, so that the shelf life of roses can be extended. Finally, it is better to put the flowers on the windowsill.
