Old stump rose potting methods and management techniques
Rose is known as the queen of flowers, with colorful and multi-seasonal blooming. Roses bloom in all seasons, in addition to outdoor appreciation, the flowers can be trimmed and placed indoors for flower art, flower baskets, etc. Rose bonsai has a unique shape and is favored by many flower lovers for its unique charm, with a poetic and picturesque ancient beauty and a natural beauty that stirs the imagination. No matter what kind of beauty, it is displayed in its unique posture. So how to take good care of a potted rose? We should create a comfortable environment for potted roses and adopt reasonable and scientific management and maintenance measures to facilitate plant growth. First, let's start with the pot for the rose!
It is important to choose the size of the pot when potting old stump roses. Since the roses are planted in pots with limited soil volume and the roses have a strong and upright growth habit with well-developed roots, the soil nutrients in the pot cannot meet the growth needs of the plants. If the pot is too small, its roots will not grow properly, which will lead to the overall growth of the rose being restricted.
The size specifications of the pot should be selected according to the size of the flowers, and I list several specifications for reference;
Old stump roses with a stem diameter of 3-4 cm are best potted in pots 40-50 cm in diameter.
Old stump roses with a stem diameter of 5-6 cm are best potted in pots 60-70 cm in diameter.
Old stump roses with a stem diameter of 7-8 cm are best potted in pots 80-90 cm in diameter.
Next, we will introduce the management of potted roses during the planting process from the following aspects.
Soil selection for old stump roses
When potting old stump roses, there are many ways to prepare the soil, usually as long as it is loose and has good breathability. More attention should be paid to ensuring that the soil is clean when preparing the soil. According to the texture of the soil, it can be divided into sandy soil, loam soil, so-called loam soil is between sandy soil and clay soil, with the advantages of both sandy soil and clay soil, having enough sand particles for ventilation and water permeability, and enough clay to retain water, heat, and nutrients. Generally speaking, the surface layer of cultivated fields and vegetable gardens that we have cultivated for many years is mostly loam soil, which has relatively high fertility and good aggregate structure, making it the main raw material for rose potting soil, and it is also convenient to use. Different places have different soil conditions; some places may have a higher sand content in the surface layer of mature soil, which can be mixed with some compost before use. Some places have stronger clay content in the surface layer of mature soil, which can be appropriately mixed with some sandy soil to improve it, having good drought and waterlogging resistance, and also being a traditional potted rose matrix. The collection of sandy soil is usually done in river gullies, abandoned fish ponds, paddy fields, and other places with accumulated water.
I give a few examples of the soil mixing ratio;
Sandy soil : Loam soil = 6 : 3, Sandy soil : Decomposed soil = 6 : 4
Sandy soil : Peat soil = 7 : 3, Loam soil : Peat soil = 7 : 3
Key points to note when transplanting old stump roses into pots
First, ensure that the soil ball does not disintegrate when digging the seedlings, and the beauty bag and the string or binding tape wrapping the soil ball do not need to be untied, and can be directly put into the pot. When potting, place a tile or stone at the bottom inside of the pot to maintain long-term breathability and convenient drainage. Then, put one-third of the prepared soil into the pot, followed by filling the soil 10 centimeters higher than the soil ball when putting the rose in the pot, then water thoroughly once, shaking the main stem of the rose while watering to let the soil settle, and finally add some soil. After the rose is potted, focus on cleaning the weak branches, residual branches, and overlapping branches, retaining healthy thick branches, reducing the size of the canopy, and retaining one-third of the canopy. Then, remove two-thirds of the leaves from the bottom of the canopy to the top. Since the Rosaceae family requires a large amount of water, it is necessary to water thoroughly every morning or evening for at least ten consecutive days after potting, watering thoroughly, and at the same time, spray the main stem of the rose with water. During these ten days, if it rains, there is no need to water. There is a detail here; the rose should not be soaked in the pot, so the holes at the bottom of the pot must remain breathable. For newly transplanted roses in the rooting stage, in order to ensure the highest survival rate, if some leaves and branches wither, they should be pruned with pruning shears. In summer, if the temperature exceeds 35 degrees Celsius under strong sunlight all day, use a shading net, usually no shading net is used. Do not use any fertilizer before it has survived.
Old stump rose thinning of buds and pruning after flowering
Each new branch of the old stump rose can produce flower buds. If all branches are allowed to grow buds and bloom at the same time, the nutrients will be scattered, the flower buds will not get enough nutrition, the flowers will not bloom very large, so it is necessary to remove some of the buds at the top of the branches, remove the small buds, and for large flower wheel branches with several buds, one largest bud should be selected and the rest should be pinched off. Avoid strong sunlight during the flowering period and place it in a semi-shaded and semi-sunny area to extend the flowering time. When the flowers are withered and have no ornamental value, they should be cut off early to avoid continuing to consume nutrients. Pruning after flowering should be done at the third compound leaf below the flower, that is, between the 3 small leaves and the 5 small leaves. Since the first bud below the cut is full, this bud will first sprout and form flower buds, and about 45 days later, the second flowers can bloom.
If the potted rose plant has a large canopy and many branches, measures such as pinching off some branches and leaving some buds on other branches can be taken. Ensure that the distribution of branches with buds and pinched branches is staggered on the plant, achieving alternating flowering of branches with buds and pinched branches, blooming and falling in turns.
Proper watering of old stump roses
Old stump roses have a strong branching force and can produce branches and bloom multiple times a year, so they require sufficient water supply. The principle of watering for potted roses is "water when dry, and water thoroughly when watering". The water should not be half-dry, that is, although the surface of the pot is wet, the soil in the middle of the pot is still dry, which will inevitably lead to the death of the rose. It is best to water in the morning on sunny days or at dusk, and avoid watering under the intense sunlight of summer. It is better to use tap water that has been stored for a few days. In summer, with high temperatures and high water evaporation, the potting soil dries easily, so it is necessary to water once in the early morning and once at dusk every day. During the plum rain season or continuous rainy days, do not let the pot accumulate water, and remove any standing water immediately.
Fertilizing old stump roses
Old stump roses like fertilizer and should be fertilized frequently with thin fertilizer to supply flowering. Attention should be paid to less fertilizing and more frequent fertilizing. Generally, fertilize once every 7-10 days. After the flowers fade and after each pruning, fertilize once. If using liquid fertilizer, it should be mainly liquid fertilizer made from decomposed animal or poultry manure, diluted with water at a ratio of 1: [6-10] before application, using a balanced NPK fertilizer (nitrogen-phosphorus-potassium 15-15-15) with a dosage of 5 grams to 10 grams each time. Usually, washing water or fishy water can also be used to water the plants directly. Fertilizing should be done on sunny days, and the soil should be loosened before fertilizing. Wait until the potting soil is slightly dry before fertilizing. Spread the fertilizer in a circle around the base of the main stem, 15 centimeters away from the main stem, and bury it in the soil. After fertilizing, spray the leaves with water to avoid fertilizer residue污染ing the leaves.
Winter pruning and flowering agreement for old stump roses
The best time for winter pruning of old stump roses is in February, which is an agreement for flowering. Winter pruning should be done during the dormant period of the roses. The dormant period depends on the climate and geographical location, usually from December to the following February, and pruning at any time during this period will not affect the flowering in spring. The best time is February. In February, new buds are germinating, and good and strong buds can be selected and retained. The reason why February pruning is the best is that after pruning in December, the buds will germinate too early under warm sunlight and then be injured by the cold in January. If pruned in March, the important nutrients accumulated in the roots will have been transported to the leaves, and pruning at this time will severely damage the plant's vitality. Therefore, the best pruning time for roses is February. This pruning is a severe cut. Before pruning, first, gather the unnecessary branches such as withered branches, weak branches, and overlapping branches. Then, reduce the height of the whole plant branches by two-thirds. The intensity of pruning is influenced by the variety and the growth rate of the plant. Generally, the 3 buds below the cut will become flowering branches. Next spring, beautiful and colorful flowers will bloom!
