Having followed the "Must-See for Rose Lovers" series from previous issues to here, I believe many rose enthusiasts have gained a comprehensive understanding of roses. Now let's talk about the daily maintenance of roses, for easy viewing, according to the climate in Beijing, it will be explained month by month.
Every January and February, supplement the basic fertilizer, dig a pit near the roots, and if possible, dig a circular trench. Put in organic fertilizer/rapeseed meal/cake fertilizer, and animal manure such as pig, cattle, horse, and sheep is even better. At the same time, mix some sulfur powder and lime, dilute it into a liquid and spray it on the plant roots to prevent pests.
In early April, after the weather warms up completely, apply a nitrogenous fertilizer and water thoroughly, aiming to make it grow strong and promote branches and buds. Urea (chemical fertilizer) is the most effective nitrogenous fertilizer, and one application in spring is enough, too much will cause excessive growth without flowering.
Mid-April is the time when young buds are most prone to aphids, so careful observation is needed. If there are a few, you can crush them by hand; if there are many, you need to spray insecticide. I use "Jusha," which works well. Be sure to eliminate aphids from mid-April to the first batch of buds in early May, as it's not good to spray after the flowers bloom. Spray once and then again three days later, which can basically eliminate them. But be sure to strictly follow the concentration specified in the instructions, only less, not more, as too much concentration can burn the buds and flowers.
In mid-May, when the first batch of flowers bloom, start supplementing phosphorus and potassium fertilizers every half-month, either by watering the roots or spraying the leaves. During the flowering period, controlling the water intake can extend the flowering period, as too much water causes the flowers to fade quickly.
From May to June, you can fully enjoy the fruits of your labor, such as taking pictures.
Note: Cut the spent flowers diagonally below one to two leaves to promote the growth of new buds. Generally, flowers will bloom again in about a month or forty days.
In late June, you can appropriately shade the plants in completely exposed areas.
In July, the rainy season begins, and occasional rain is fine, but prolonged rainy weather can cause various fungal diseases. From July, regularly spray fungicides such as carbendazim or thiophanate-methyl to prevent mold. Also, spray insecticides to control various small caterpillars. The article is from: https://
In August and September, cut off the new side branches that do not bloom on the stems and some wild branches that affect the plant shape, to save nutrients and prevent diseases caused by dense foliage. At the same time, supplement a slow-release fertilizer to prepare for a flourish in autumn.
The small branch on the left in the picture is a non-flowering side branch, which is very short and looks old, cut it off close to the root.
From late October to November, you can start transplanting or repotting. For those planted in the ground for more than two years or in too large pots, remove 5 to 8 centimeters of surface soil and replace it with new mixed nutrient soil.
From December to February, you can prune the whole plant and cut suitable branches for propagation.
Special attention should be paid to the following points:
1. Daily watering should be done when the soil is dry and then watered, roses like it, but the roots are very afraid of waterlogging, so don't let it sit in water all the time. Water more in hot weather and less in cold weather, never water under the scorching sun, and water in the morning and evening during extreme heat. Try to water the roots to prevent any pathogens on the upper leaves from flowing down to the lower leaves and causing a whole plant infection.
2. Roses like a lot of fertilizer, but it must be applied frequently and thinly - a lower concentration is safer. From mid-May to mid-October, supplement phosphorus and potassium liquid fertilizer every ten days, and reduce the concentration of fertilizer and water during extreme heat.
3. Roses like plenty of sunlight but are afraid of direct exposure, as more than half of the varieties will scorch and curl in the hot sun. Use the lightest sunscreen net to provide some shade. For potted plants, move them to the shade during the strongest sunlight to avoid heat.
