Can Rose be Grown in Water? Hydroponic Methods, Precautions, and Why It Should Not Be Grown in Water for Long

As an excellent choice for home cultivation, roses are often grown in yards because of their large size. But many flower lovers want to grow them indoors. What should they do then? Many people think of hydroponics. So can roses be grown in water? It is said that roses have extremely strong vitality and strong resistance, so they can be grown in water. As for the hydroponic method for roses, let me introduce it to you in detail.

I. Can Roses Be Grown in Water? Yes

Because they can grow even by roadsides in the wild, it is clear that roses have very strong vitality, so can roses be grown in water? Of course they can. However, everyone should note that roses can be grown in water, but not for the long term! Flower lovers can try hydroponics to root them, and when the roots grow to about 3 cm, switch to soil cultivation.

Friends who want to see roses bloom in water may be disappointed, because water lacks nutrients and can hardly support roses until they bloom. Even if they do bloom, it will not be attractive. Of course, before the roses bloom, they can be grown in water for foliage, since the tender green leaves are quite beautiful.

II. Hydroponic Methods and Precautions for Roses

Tools: plastic bottle, scissors, cardboard

To grow roses in water, you first need to prepare water and a bottle, and then select good cuttings. The specific steps are as follows:

1. Choosing the Water

For the water used to grow roses hydroponically, do not directly choose tap water from the pipe. You can use overnight water, or cooled boiled water.

2. Choosing the Container

Before hydroponics, prepare a container to hold the roses. A simple plastic bottle will do; if you want it to look nice, you can choose a beautiful glass bottle.

3. Choosing the Cuttings

For hydroponics of a plant, the most critical thing is the selection of cuttings. Good cuttings mean the hydroponics is already half successful. First cut rose branches, choosing semi-lignified green branches with buds. Then simply prune the branches, keeping 2 to 3 leaves.

4. Starting Hydroponics

Insert the prepared cuttings into the bottle, as shown in the picture above. This tea beverage bottle is quite good. To make rooting easier, I prepared a piece of cardboard, poked a few holes, and inserted the cuttings through the holes into the water.

After completing the above work, the hydroponics of roses is basically done. At this point, place the bottle in sunlight, and roots will grow in about one and a half months. After rooting, you can switch to soil cultivation. How to care for them afterward is described in detail in the rose cultivation methods, so I will not say more here.

Changing water: Before roses root, change the water once every 3-4 days. After rooting, change the water less often, and add water promptly after evaporation. Check whether the water has gone bad. If the water has a rotten smell, check whether the roots have rotted, and if so, promptly clean off the rotten parts and let them re-root.

How to Grow Roses in Water

Below I will introduce a simple method. The tools can all be simplified.

First cut rose branches, choosing semi-lignified green branches with buds.

Then simply prune the branches, keeping 2 to 3 leaves.

Just insert the branches into the bottle. Look, this tea beverage bottle is not bad.

Ok, place the branches in sunlight, and roots will grow in about one and a half months.

Precautions for Growing Roses in Water

Before rooting, change the water once every 3-4 days. After rooting, change the water less often, and add water promptly after evaporation. Do not directly choose tap water from the pipe. You can use overnight water, or cooled boiled water.

Check whether the water has gone bad. If the water has a rotten smell, check whether the roots have rotted, and if so, promptly clean off the rotten parts and let them re-root.

Do not fertilize too frequently. Too much fertilizer will burn the roots and also cause yellow leaves. You can put a rusty screw in the water to supplement iron.

Roses: Propagation Methods and Cultivation Precautions

The rose is one of the world's famous ornamental plants and has a long history of cultivation in China. As far back as 1630, when Wang Xiangjin wrote the Qunfangpu, in 1688 when Chen Haozi wrote the Michuan Huajing, and in 1708 when Wang Hao wrote the Guang Qunfangpu, there were already records of roses, Chinese roses, Damask roses, and banksia roses. Below let us take a look at rose cultivation methods and precautions!

Rose Propagation Methods

Rose seeds can be used for raising seedlings, but in production, softwood cuttings from the current year are mostly used for propagation, as they root easily. Precious varieties are harder to root from cuttings and can be propagated by layering or grafting. Seedlings from asexual propagation can bloom in the same year. For seedlings used as potted flowers, choose older branches from superior varieties and propagate by layering, and also pay attention to pruning the main buds and carrying out artificial dwarfing. For seedlings used as cut flowers, choose varieties that can form flower-bearing mother branches and have large, brightly colored flowers. Roses can also be propagated by tissue culture, hydroponics, grafting, division, and other methods.

Rose Cultivation Methods

1. Soil: Roses are not strict about soil. They are drought-tolerant and tolerant of poor soil. For cultivation, soil that is deep, loose, fertile, moist, and well-drained is most suitable, though they can also grow normally in heavy clay soil. Whether planted in the ground or in pots, the best growing medium for roses is fully decomposed sandy soil.

2. Light: Roses are light-loving flowers and prefer ample sunlight. They also tolerate partial shade and are fairly cold-tolerant, with extremely strong adaptability. Except for overwintering in severe winter cold, they are suitable for planting throughout southern China. During the growth period, roses should be guaranteed sufficient sunlight so they can grow lush branches and leaves and bloom more.

3. Watering: Roses like moisture but fear waterlogging and are averse to waterlogging. From budding to before blooming, you can water a little more, with the best condition being moist soil but no standing water. After the roses finish blooming, watering should be reduced. When watering, the soil should alternate between dry and wet. In the rainy season, pay attention to drainage and waterlogging prevention to avoid root rot from standing water.

4. Fertilizing: Roses prefer fertilizer but also tolerate poor soil. In March, apply 1 to 2 times a nitrogen-based liquid fertilizer to promote lush branches and leaves. In April and May, apply 2 to 3 times a phosphorus- and potassium-based fertilizer to encourage more buds and more blooms. After flowering, apply one more rejuvenation fertilizer, and then stop fertilizing. Roses need hilling and fertilizing once each winter.

5. Pruning: Pruning and shaping is an indispensable step in growing most flowers, and naturally roses are no exception. Especially when growing them as potted flowers, even more attention should be paid to pruning and shaping. Generally, mature rose plants are pruned once each year before spring growth begins, with a moderate amount, ensuring the branches are neither too sparse nor too dense and the shape is attractive. Every winter, old branches and densely growing branches of roses should be pruned regularly to maintain good light penetration and ventilation, which can reduce pests and diseases.

Precautions for Roses

1. Rose Anthracnose

[Symptoms] Lesions appear on leaf margins, semicircular, with dark brown edges and brown to light brown centers. Later, small black dots form on the lesions. The pathogen overwinters on diseased fallen leaves. Under warm, humid conditions, spores germinate and infect leaves. When plants are too dense and moisture lingers for a long time, the disease is more likely to occur. Anthracnose mostly occurs sporadically and can be controlled at the same time as black spot and leaf spot.

[Control] At the end of autumn and beginning of winter, clean the garden promptly and collect diseased fallen leaves to burn in a centralized manner. Strengthen maintenance, prune appropriately, and thin out overly dense branches to ensure good ventilation and light penetration. When necessary, spray 20% Longkejun (thiodiazole-copper) suspension concentrate at 500 times dilution, or 78% Kebo (bordeaux mixture) wettable powder at 600 times dilution, 75% Daconil (chlorothalonil) wettable powder at 600 times dilution, 50% Shibagong or Shibaike (prochloraz) wettable powder at 1000 times dilution, or 25% Tanteling wettable powder at 500 times dilution.

2. Rose Powdery Mildew

[Symptoms] Leaves, petioles, young shoots, and flower buds can all be affected. Irregular white powdery mildew spots form on mature leaves. Diseased leaves gradually turn brown starting from the leaf tip or margin, causing the whole leaf to dry up and fall off. When young leaves are infected, chlorotic spreading spots appear and gradually expand, with indistinct edges. White powdery spots form on both sides of young leaves, then cover the entire leaf, and the leaves turn light gray or purplish red. New leaves become wrinkled and deformed. After petioles and young shoots are infected, the internodes shorten, the stems become thinner, and some diseased shoots dry up, with the diseased parts also covered in white powder. When flower buds are infected, the buds and pedicels are covered in white powder, and the calyx, petals, and pedicels become deformed. In severe cases, they shrivel and die, losing ornamental value. The powdery mildew pathogen overwinters on diseased buds. Planting too densely, applying too much nitrogen, poor ventilation, and insufficient sunlight make the disease more likely to occur.

[Control] Choose powdery mildew-resistant varieties. When pruning in winter, be careful to cut off diseased branches and diseased buds. During the disease period, apply less nitrogen fertilizer and more phosphorus and potassium fertilizer to improve disease resistance. Pay attention to ventilation and light penetration, drain promptly after rain, and prevent moisture from lingering, which can reduce disease occurrence. In the early stage of the disease, spray 20% triadimefon emulsifiable concentrate at 1000 times dilution, or 20% triadimefon-sulfur suspension concentrate at 1000 times dilution, or 50% carbendazim wettable powder at 800 times dilution. If resistance develops to the above fungicides, switch to spraying 12.5% myclobutanil emulsifiable concentrate or 30% Triforine wettable powder at 3000 times dilution. In early spring before budding, spray 2-3 degrees Baume lime sulfur mixture or 45% crystalline lime sulfur mixture at 40-50 times dilution to kill overwintering pathogens.

3. Rose Beetles

[Characteristics] Rose beetles mainly harm roots, leaves, flower buds, and other parts, seriously affecting flower yield and quality.

[Control] Use light trapping, poplar and willow trapping, shaking to catch and kill, and so on. When damage is severe, spray 2.5% deltamethrin at 2000-3000 times dilution or 50% phoxim at 1000-1500 times dilution. Both are quite effective, but they must never be sprayed during the flowering period.
