Buying flowers directly can purify water quality, promote water absorption, prevent withering and provide basic nutrition for flowers. This is the easiest way to keep roses fresh for a long time. Many flower shops use this method, which can basically prolong the flowering time of flowers by more than twice, which means that your roses can be kept for at least 3 weeks.

2, tea preservation method

Raising flowers with tea can prolong the flowering time of flowers. This is because the nutrients in tea (such as tea polyphenols) can prolong the flowering time of flowers. Generally, roses can only be preserved for about 7 days in clear water, and 15 days in tea.

3. Pruning method

It is a troublesome thing for the pruning master to prolong the fresh-keeping time of roses. It is required that the temperature of roses should not be too low, just two or three degrees below zero, and it should be in a cool place and not in the sun. Prepare a bucket of clear water (subject to that the whole bunch of tied roses can be put down), put the tied roses in advance, change the water once a day until the water is less than 8 to 10 cm, and cut the branches once every two days.

4, slope pruning method

You can also cut a branch at the bottom of a rose on a slope and put it in a bottle. Because the inclined plane will increase the cross section of the flower branch in contact with water, it will keep the flower branch for a longer time.

5. Deep water first aid method

When the rose shows signs of withering, you can cut a short section at the end of the flower branch and put it in a container filled with cold water, leaving only the flower head exposed to the water. After an hour or two, the flower branches will slowly regain their vitality. Finally, if it is really not well preserved, it can be made into rose tea. After all, the efficacy and function of rose tea is still very powerful.

The cultivation method of rose is as follows:

1, soil

Roses like loose and fertile slightly acidic soil, and their air permeability and water permeability must be good. Rotten soil is the best choice for growing roses. It is not only loose and breathable, but also nutritious. However, it has good water retention. Therefore, in order to prevent basin soil from accumulating water, a part of granular soil should be added to the decomposed soil to enhance the drainage of the soil.

2. Water and fertilizer

Roses are drought-tolerant and avoid waterlogging. Watering should be based on the principle of no watering, but it should be watered thoroughly. Usually, the water in the basin should be avoided or too wet and waterlogged, especially before and after flowering. Pay more attention to watering when the soil in the basin is dry.

Roses like fertilizer, and liquid fertilizer should be applied every half month during the growing period. You can mix the decomposed cake fertilizer with bone meal, dilute it with water, and then dump it. Before flowering, we should add 1~2 times of phosphorus and potassium fertilizer to facilitate the flowering of roses.

3. Temperature and lighting

Roses like the growth environment of warm sunshine, are relatively cold-resistant, and are suitable for growing in the warm environment of 15~25 degrees; Roses are positive plants, and it is better to have no less than 6 hours of sunshine every day. If the light is insufficient, it will grow white without flowering. Family potted roses should be placed in Nanyang terrace, sunny south windowsill and other sunny places for maintenance.
