Friends discuss the cultivation methods of roses
The website introduces content about roses, such as the friend's discussion on the cultivation methods of roses. The specific content is as follows:
The knowledge involved in growing flowers is fragmented, and I don't know how to write it well. I try to write in detail, and fortunately, we don't look at advertisements, we look at the effects, and only effective methods are good, haha!
Even ancient-level flower friends come to contribute some dried content, and the team of flower friends will grow rapidly.
Directly into the topic
After obtaining a normal rose plant (toothpick, old seedling), it is first planted in a well-ventilated medium, then the seedling is acclimatized. The length of acclimatization time depends on the condition of the seedling, mainly referring to the root system. If it is planted with complete soil or a nutrient block, there is no need for acclimatization. If it is bare-rooted, after planting, wait until the branches are full before slowly exposing to the sun.
Planting should choose a flower pot as large as possible (later, potless planting can be done, which is extremely breathable, and you can imagine the growth rate of the seedling) and as little medium as possible (1-2 cm higher than the root system of the seedling) and shallow burial (the seedling grows strong and fast, easy to manage and control), except in winter. The leaves of the seedling should be retained as much as possible and not randomly removed (the basis for the rapid growth of the seedling). If the seedling has no leaves (bare stem) after receiving it, water it thoroughly and then promote the buds (promoting buds is the same as rooting in a sense).
Ps How to promote buds: Find a plastic bag, preferably red, cover the pot, make a hole the size of a one-yuan coin in the top center, place it where the sun can shine directly, generally 1-3 days for the buds to sprout. If the buds sprout, remember to remove the plastic bag at this time (to prevent high temperature and humidity causing bacterial growth), select the buds, keep the strongest bud for the toothpick seedlings, and remove the other buds. For larger seedlings, do as you see fit, then place the seedlings in a shaded place for 7-10 days (mainly depending on the condition of the leaves) before gradually exposing to the sun. This way, the plant growth cycle is connected, and the rest is fine-tuning and accelerated growth. If no buds have sprouted within 3 days (which is very unlikely, even bare branches in the pot will sprout), also remove the plastic bag, ventilate for 2 days, and repeat. Never cover the bag in summer, summer bud promotion can use the cooling method (thoroughly water the pot, shade the pot), spring and autumn bud promotion can use the warming method (cover the bag).
Fast growth (effective for young seedlings, cutting seedlings, weak seedlings):
If the planting medium can dry out and require watering every day, and the seedlings can be watered with fertilizer every day, the root system will have sufficient nutrition, the evaporated part can be used as foliar fertilizer, and the plant will grow fast. How to water every day? Potless planting (not ground planting) has the best effect.
Ps About potless cultivation: As the name implies, it does not use flower pots, which is super ideal for traditional media, simulating the benefits of ground planting plus the advantages of potting, super breathable, and most suitable for young seedlings. There are many methods, such as finding a tray or plate, making a circle or square with plywood or a carton, any size (as long as it doesn't exceed the tray), place it on the tray, then plant the young seedlings, water, and after the medium is half-dry, remove the plywood or carton.
You can also plant young seedlings in a larger pot, remember the radius of the young seedling roots around the center of the pot, water, half-dry after using a small trowel to dig out about 2 cm away from the pot edge...
How to promote rapid growth of leaves and branches, forbidden in summer, not suitable for beginners (see the bottom of the article for tips 4)
If the bare-rooted seedling has poor root system and needs to acclimatize, and the absorption cannot keep up, what should be done (especially for toothpick bare-rooted seedlings)? Only the leaves can absorb some nutrients and water (which can also be used for root growth). The most important thing during this period is water. Cover the bag at night (the same method as promoting buds, so that the evaporated water vapor and fertilizer must pass through the seedling and leaves before evaporating, and the leaves act as roots at night, supplementing water and nutrients), remove the bag during the day, and provide sufficient sunlight or scattered light (not direct sunlight, photosynthesis during the day synthesizes sugar and starch for root growth, etc.). The early growth of the plant should be allowed to grow freely, and only after it has many branches and leaves can the new buds be strong and robust. Trim according to your preference at this time (don't turn it into a monk). Leaves and branches are particularly important for balcony and low-light gardeners.
About water and fertilizer topdressing (organic fertilizer is the best all-round fertilizer):
1. The fastest-acting nitrogen fertilizer is animal or human urine. Find an old drink bottle with a mouth smaller than a Jinlongyu (5-liter pot) oil pot, cut it in half and turn it upside down to make a funnel, fill the Jinlongyu 5-liter oil pot, seal it tightly, and ferment for 3-7 days at 30 degrees or 10-15 days at 20 degrees. Fermentation is complete when there is no urine smell, then dilute with water or other water fertilizers and water the flowers.
2. Phosphate fertilizer, such as sesame hulls (available at many small grinding oil sales points), soaked in water (the preparation method is the same as nitrogen fertilizer), and rice washing water (the preparation method is the same as nitrogen fertilizer), crush calcium tablets and sprinkle on the surface of the medium (do not contact the seedling) and water normally.
3. Potassium fertilizer, such as wood ash or tobacco ash, soaked in water and watered directly. Soak soybean dregs or legumes in water (use only the top water) and water the flowers, and do not waste the sediment, which can be used as a base fertilizer.
Water and fertilizer topdressing efficacy: Excluding the loss due to leakage, wind, and other factors, it is generally 7 parts absorbed by the roots and 3 parts absorbed by the leaves. In a fixed amount of time, the 3 parts absorbed by the leaves is equivalent to 7 parts absorbed by the roots because the leaf surface has a much larger absorption area than the roots.
About planting medium:
There are many ways to configure and use planting media. It would take too much space to explain them all. First, determine the planting purpose, then configure the medium, and the configured medium + management method = good results. Here is a simple, widely used, easy-to-find, and economical configuration method, which has the disadvantage of being heavy, dry, and very dry and hard. The purpose is for cutting seedlings to acclimatize and grow rapidly.
Garden soil (yellow clay, red clay, black clay, i.e., very ordinary soil) 50% + sand (coarse sand, fine sand, i.e., very ordinary sand) 50%, mix well and use. Characteristics: Good ventilation and drainage, slightly moist, moist, very moist, and very loose when thoroughly watered.
Usage method: Place 4 cm of soil at the bottom of the pot, place the seedlings, then cover the roots with the medium and water thoroughly with water fertilizer, and water with water fertilizer every time thereafter. The water volume is 2/3 of the thoroughly watered amount, slightly moist or slightly dry requires watering. When each branch has 35 to 50 leaves, add about 10 cm of medium to the bottom of the pot and add base fertilizer. When adding the medium, make sure it is slightly dry, as the medium is too loose (base fertilizer is separated from the roots by 2 cm of medium, and adding medium is similar to potting, except that it is not necessary to change pots yet, if you change, it's also fine).
It is best to apply what you have learned and draw inferences from one example to another. For example, promoting buds, the premise is a normal seedling, if the seedling has powdery mildew, you need to cover the bag, and the mildew can go crazy. If covering the bag, first wait until the powdery mildew is gone before doing so.
Tips:
1. Powdery mildew: Ventilation, sunlight, keep the leaf surface dry for about 7 days, and it can basically heal (except for special varieties).
2. Plants mainly use two types of light, red light and ultraviolet light, which is converted into blue light, and other colors of light have little effect.
3. Adjusting the soil pH, if the soil is too acidic, you can use wood ash or tobacco ash (with a pH of 8-9, alkaline) to soak in water and water the flowers to adjust, which is very effective and safe for the seedlings (green method, very effective). If the soil is too alkaline, you can use oxalis (with a pH of 2, acidic) to soak in water and water the flowers to adjust (usually twice for a 50 cm diameter pot), which is also very effective and safe for the seedlings (green method, very effective). There are many other green and safe methods, such as tomatoes (tomatoes), etc., you can test them yourself.
4. The benefits of covering the bag are numerous, from January to April, it can speed up seedling growth, rapid acclimatization (weak seedlings, only a few roots, can generally recover safely and quickly), leaves cannot absorb water, but can absorb water vapor and elements (some fertilizer elements).
5. Roses can tolerate drought, but they prefer moist soil, which is beneficial for rapid root growth because moist soil has loose soil, sufficient water, and fertilizer elements are easily synthesized and mobile, etc., which are conducive to plant growth. Whether to see dry and wet is a matter of personal opinion, and it is necessary to apply what you have learned depending on the condition of your planting medium.
