Fertilizing Methods and Key Techniques for Field-Grown Roses
Rose generally refers to the rose flower, also known as Yueyuehong, Yueyuehua, Changchunhua, Sijihua, and Shengchun, and is often grown as a potted plant or as an ornamental garden flower.So how do you fertilize field-grown roses?
1. How to fertilize field-grown roses?
Before fertilizing field-grown roses, you can dig a trench 1-2 m around the plant, then scatter the prepared fertilizer into it, and cover the fertilizer with the original soil. This ensures as much as possible that the fertilizer will not fail to release nutrients due to exposure to the sun, nor will it have a low utilization rate due to evaporation with rainwater.
2. How to care for field-grown roses?
1. Watering
You can build a ring-shaped soil berm around the rose and water inside it. In hot weather, water every 1-2 days; in cooler weather, every 3-4 days; in winter, reduce as appropriate.
2. Pruning
Field-grown roses should be pruned when they are close to sprouting and stopping dormancy, in late autumn and early winter. There are three forms of pruning: light pruning, moderate pruning, and heavy pruning. Light pruning is shortening healthy branches and removing two or three inward-growing buds; moderate pruning is cutting last year's healthy branches back to the base or cutting them in half; heavy pruning is keeping only 3-4 branches from last year's growth on the whole plant, leaving only 3-4 buds at the base. When pruning, cut about 0.5 cm above a bud, with the cut surface slanted and smooth and flat. After pruning, protect the wounds well to prevent invasion by pests and diseases, and burn the cut branches and leaves in a centralized manner.
3. Overwintering
In the severe cold winter areas of the north, roses need certain cold-protection measures to overwinter normally and safely. There are several cold-protection measures: plastic film mulching, burying with soil, setting up windbreaks, wrapping, etc.
Field-grown roses are easier to fertilize than potted ones, and the requirements are somewhat lower. As long as their basic needs are met, along with proper care, they can bloom with a tree full of roses.
