How新手 can grow good rose seedlings
Do you understand these? Introduction to green plants and flowers on how新手 can grow good rose seedlings, let's take a look together.
Autumn and winter are good times to plant roses, but many新手 gardeners always say "the seedlings bought can't survive more than a month." What is the reason for this? What should be done to grow the rose seedlings well?
How新手 can grow good rose seedlings
Among the many varieties of flowers, roses are easy to survive but difficult to grow well. Many gardeners can't grow roses well, and the main reasons summarized are these four points. Doing any one of them wrong can lead to the withering of roses.
1. - - Overwatering - -
Many gardeners water their potted plants based on their feelings. They water when they feel the rose potted plant needs it, without considering the actual dryness or moisture of the potting soil. Even when the soil is very damp, they still water, which can lead to waterlogging in the pot. The direct result is that the roses will rot the roots, which is manifested in the leaves as yellowing of new leaves or leaves falling off when touched, ultimately leading to complete withering.
So, the first step to keeping a rose potted plant alive is to learn how to water. As the saying goes, "watering takes ten years of practice," which shows how difficult it is to water flowers. However, no matter how difficult the task, there are rules and skills to choose from.
Here's a simplest method to judge the watering time for potted plants: before watering, lift the pot to feel its weight. If the pot feels light, it's time to water; if it still feels heavy, it means the potting soil is not dry and doesn't need watering. However, this method requires that the pot you use is made of a lightweight material, and the potting soil should not be heavy, otherwise it will affect the judgment.
Without mastering enough gardening skills, I personally recommend using plastic pots with more drainage holes, such as gallon pots or root control pots, instead of ceramic pots. The potting soil should be nutrient-rich, which will greatly reduce the difficulty of maintenance.
2. - - Eager to fertilize - -
Many gardeners, as soon as they receive the seedlings, think about repotting and fertilizing, which is not a good idea. If the seedlings are in a soil ball or bare-rooted, they should be planted immediately after receiving them. But if the seedlings are in a pot, even if it's just a propagation container, it's best to keep the original pot in a bright area with diffused light to acclimate the seedlings. This is the most standard and correct method.
Of course, with some gardening experience, we can handle the seedlings based on their condition. But whether repotting or not, within a week of receiving the seedlings, it's a period of acclimatization, and it's strictly forbidden to apply water-soluble fertilizers because the root damage has not yet recovered, and fertilizing can easily cause fertilizer burn.
For seedlings that are being maintained originally, a dilute fertilizer can be applied five days after acclimatization. If repotted, a week after repotting, water-soluble fertilizer can be applied. When repotting, only fermented organic fertilizer and slow-release fertilizer should be used as base fertilizer, and they should not come into direct contact with the roots. Note that compound fertilizer cannot be used as a base fertilizer because it can easily cause fertilizer burn. The usage of various fertilizers is detailed in the book "How to Bloom Roses," which you can refer to.
3. - - Over-pruning - -
Many gardeners have heard that roses need to be pruned regularly, so when they receive the seedlings, they cut them directly with pruning shears, leaving only a stick. Although cutting into a stick may not necessarily cause the rose to wither, it greatly increases the possibility of withering.
In spring, summer, and autumn, roses are in the growing period, and it's best to have a lot of leaves for photosynthesis. If there are no leaves, the photosynthesis rate of roses decreases, less nutrients are produced, the transpiration rate is low, the potting soil dries slowly, and watering slightly carelessly can cause root rot. Combined with improper fertilization, the plant may turn black directly.
So, except for winter, don't prune roses lightly. In the growing period, only light pruning is allowed. For plants with many leaves, the pruning amplitude generally does not exceed 1/2, and for roses with fewer leaves, only residual flowers and flower buds should be pruned, trying to keep more leaves. Once roses lose their leaves, it's necessary to strictly control watering and wait for new buds to grow.
4. - - Eager for growth - -
Many new gardeners are eager for their seedlings to grow and bloom. Especially when the seedlings have growth problems, they always try various methods, such as applying pesticides, fertilizing, and watering root growth powder. In fact, when the seedlings are weak, the wisest choice is to do nothing and let them adapt.
For example, if we cause fertilizer burn to the roses by fertilizing, and many leaves turn yellow, we only need to water the roots with a large amount of water first, then avoid direct sunlight and prevent waterlogging in the pot, and let it recover slowly on its own. Don't think about changing the soil, as it will only cause secondary damage. Wait until the rose seedlings show明显的 growth before gradually resuming normal management.
