1, check the pruning.
In order to prolong the fresh-keeping time of rose bouquets, it is necessary to check the growth of plants after buying them home. After the leaves are found to be yellow and withered, they need to be trimmed in time to remove the leaves at the bottom. Then cut the flowers short and trim them to 45? Bevel to increase the water absorption area of branches.
Step 2 replenish water
After that, you can insert the pruned roses into the vase for maintenance. You can choose a transparent glass vase as a culture container and pour two-thirds of water into it. Be careful not to pollute the leaves with water, otherwise they will turn black and wither easily. In the later maintenance, change the water in time when the water quality becomes worse.
3. Suitable environment
Roses are suitable for growing in a ventilated environment. If the environment is too closed, it will lead to a large number of bacteria, which will make the flowers wither and turn black. Therefore, opening the window every morning and closing the window at night can maintain the normal growth of roses.
Step 4 supplement nutrition
In order to prolong the fresh-keeping time of roses, it is necessary to add 2 ~ 3 drops of nutrient solution to water during daily maintenance to supplement the nutrients needed for growth, and spray potassium dihydrogen phosphate solution on branches and leaves regularly to prolong the flowering time. Later, when the branches and leaves are found to be dry and yellow, they should be trimmed in time to reduce unnecessary nutrient consumption.
