How to Water and Fertilize Roses and How They Differ from Rosa multiflora

The rose is a symbol used to express love and convey beauty, and many friends use it to add luster to their romance. The rose originates in China and blooms only once a year, so it is rarely used for breeding; recently the traits chiefly valued in it have been disease resistance and cold hardiness. So how do you water roses? How do you fertilize roses? And what are the differences between the stems of roses and Rosa multiflora?

1. How do you water roses?

When watering, it is usually better to use soft water; especially on rainy days, rainwater is the most suitable for irrigating roses. You can then choose water from a pond or river for irrigation. If you want to use tap water at home for watering, you need to leave it in the sun for a day before using it; exposure to sunlight can eliminate the chemical components in tap water. Also note that you must not water with the water we use for washing clothes or dishes, as this easily affects the health and appearance of the flowers; we can use vegetable-washing water and rice water to water the flowers.

1. Water quality

When watering, the water temperature is fairly important; water temperature that rises and falls erratically has a certain effect on roses and can easily cause roses to develop diseases. The water temperature should be kept at a normal temperature. In spring, you can water more at midday, and the water temperature is also more reliable then. In summer, you can water in the evening, while in autumn and winter you can reduce the amount of water.

2. Water temperature

Watering roses is best done in the morning, as this can promote their normal growth; some plants need to be watered in the morning. During the period of vigorous growth, roses need a large amount of water, while during winter dormancy, reduce the amount of water applied. When watering, you can use surface watering of the pot, drip irrigation, or the moisture-absorption method. If you cannot tend to them in time for a period, then use the moisture-absorption method to water the roses; this allows them to keep a continuous and sufficient supply of water without causing water to accumulate in the pot, and it is suitable for use when you cannot manage them for a long time.

3. Water quantity

When watering, you must have a good grasp of how much water to use, so as to ensure that the plant has a good absorption effect.

2. How do you fertilize roses?

1. When fertilizing roses, only a small amount of fertilizer is needed; using too much fertilizer will cause root rot and can easily burn the roses to death. We can add a small amount each month in a certain proportion according to the flowerpot and the growth of the roses. If the roses are growing well, you can water them with the water normally used for rinsing rice, and then you do not need to apply other fertilizers.

2. Pay attention to the effect of pests and diseases on roses; roses are usually harmed by aphids, and we can spray some insecticide to prevent the intrusion of pests and diseases.

3. When choosing soil, ensure the soil's moisture and its air and water permeability, and choose garden soil containing humus, as this can make the roses grow more robustly. Every spring, change the soil for the roses once, always maintaining a good growing environment. In seasons with frequent rain, roses will develop white mold disease because of the high humidity in the air, and at this time they need to be treated with medication as soon as possible.

3. Differences between the stems of roses and Rosa multiflora

1. Rose: The rose is an erect shrub, up to 2 m tall, with thick, black, clustered stems; the branchlets are densely covered with down and have needle-like prickles and glandular hairs, with upright or curved, pale yellow prickles, and the prickles are covered with down on the outside.

2. Rosa multiflora: Rosa multiflora is a climbing shrub; the branchlets are cylindrical, usually hairless, with short, thick, slightly curved bark strands; the stem prickles are relatively large and generally hooked, roughly 3-4 per node.

Leaves:

3. Rose: The rose has 5-9 leaflets, 5-13 cm long including the petiole; the veins are sunken and wrinkled, the underside is grayish green, the midrib is prominent, the netted veins are obvious, and it is densely covered with down and glandular hairs, sometimes the glandular hairs are not obvious.

4. Rosa multiflora: Rosa multiflora also has 5-9 leaflets, sometimes 3 on the leaflets near the inflorescence, 5-10 cm long including the petiole; the upper side is hairless, the underside has soft hairs; the petiolules and leaf rachis have soft hairs or are hairless, with scattered glandular hairs; the stipules are comb-toothed, mostly adnate to the petiole, and the edges have or lack glandular hairs.

Flowers:

5. Rose: The rose's flowers are solitary or in clusters of 1-3, in a paniculate corymb borne at the top of the branches; the flower stalk is short, the flower diameter is about 3 cm, and it also blooms only once, in summer, but the fragrance of the rose flower is much stronger than that of Rosa multiflora; after the flowers fade, the sepals do not fall off.

6. Rosa multiflora: Rosa multiflora's flowers are often in clusters of 6-7, in a paniculate corymb borne at the top of the branches; the flower diameter is about 3 cm, it blooms only once a year, and after the flowers fade the sepals fall off.

Fruit:

7. Rose: The rose's fruit is oblate, 2-2.5 cm in diameter, brick red, fleshy, and smooth.

8. Rosa multiflora: Rosa multiflora's fruit is nearly spherical, 6-8 mm in diameter, reddish brown or purplish brown, glossy, and hairless.
