What to Do When Potted Roses Get Bugs? Methods for Spraying Pesticides to Prevent and Control Pests and Diseases

Any plant can get bugs, and of course roses are no exception. Roses are one of the easiest indoor flowers to grow, with a very high survival rate, but if you care for them poorly, you can also kill them. The most common pest on roses is the red spider mite, which causes the leaves to gradually turn yellow and wither. So what should you do when roses get bugs? Let's take a look at pest and disease control for roses.

I. What to Do When Roses Get Bugs: Spray Pesticide Immediately

Roses are plants that love light very much. If they are kept out of light for a long time, they will develop symptoms and get bugs. It is very common for roses to get bugs, and there are many reasons for it, so you need to treat the root cause. The most common bugs are red spider mites, aphids, thrips, and so on. What should you do when roses get bugs? Let's look at the methods for pest and disease control in roses.

II. Pest and Disease Control for Roses

Spider mites, also called red spider mites, mainly come in two types that harm roses: one is the carmine spider mite, which is insect-red in color, and the other is the two-spotted spider mite, which is insect-yellow to yellow-green.

Symptoms: Generally, spider mites parasitize the underside of leaves and suck the sap, while many tiny yellowish-white spots appear on the upper surface of the leaves, and then the leaves slowly turn yellow and finally fall off. In severe cases, the entire flower buds and branches will be covered with spider mites.

Solution: During the dormant period, you can evenly spray lime sulfur mixture, and in the early stages of occurrence, spray abamectin as well as propargite, fenbutatin oxide, chebamectin, and so on.

2. Flower aphids

Aphids gather on the buds, tender leaves, and flower buds of roses and suck their sap. In severe cases, there will be honey-oil-like black secretions, which affect flower quality and rose growth.

Solution: When aphids lay eggs to overwinter in autumn and winter, you can alternately use imidacloprid and abamectin for control.

3. Thrips

When thrips dwell on tender leaves, they cause the tips to die, preventing growth. If they feed on the back of leaves and also excrete brown matter, it causes the back of the leaves to become deformed, and gray-white or gray-brown stripes appear on both sides of the midrib, with deformation and bending.

Solution: For this situation in rose pest and disease control, you can spray chemicals for treatment, choosing those containing active ingredients such as imidacloprid, acetamiprid, and thiamethoxam.

4. Rose stem sawfly

It occurs one generation per year. In April-May, it lays eggs under the epidermis of the inner diameter, and after hatching, it drills into the stem, then cuts downward in a spiral along the cambium to bore and feed, all the way to the lower part of the branch. After maturing, it makes a pupal chamber inside the branch, which is barrel-shaped.

Solution: An effective control method is to cut off the diseased branches, cutting downward until you find the larvae, and then destroy them.

5. Atractomorpha sinensis

Atractomorpha sinensis bites many holes in the leaves. It occurs 2 generations per year, lays eggs in winter to overwinter, and the eggs hatch into adults in May-June.

Solution: You can spray a 50% fenitrothion 1000-fold solution, which has a very high mortality rate and very good effect.

What to do when potted roses get bugs? Based on the description above, everyone can identify the cause and treat it accordingly. The above is the complete answer on pest and disease control for roses. I hope it can help you.

20 Little Tips for Growing Flowers at Home; Once You Learn Them, It Will Be Hard Even If You Want to Kill Them!

   Growing flowers at home seems easy but is actually difficult, especially when the seasons change. A good flower can accidentally die. So how can we ensure that the flowers we grow stay alive and well? Follow the editor of Huinong Network to learn 20 little tips for growing flowers at home! Once you learn them, it will be hard even if you want to kill them!

   As soon as autumn begins, the weather starts to become hot and cold unpredictably, and with one careless moment, the flowers at home die off. So today Huahua introduces some little secrets for growing flowers. As long as you learn them, it will be hard to kill the flowers at home even if you want to!

   Choose the right suitable location

   If you want to grow flowers well, first you need to know what kind of flowers are most suitable for the environment at home.

   1. South balcony with full sun:

   A south-facing balcony with ample light is most suitable for growing flowers that like direct sunlight, meaning these flowers grow better the more they are exposed to sun. For example, moss rose, blue plumbago, petunia, and orange jasmine.

   2. East balcony with half-day sun:

   An east-facing balcony only gets sun in the morning, and once noon comes, the sun is gone, so you can grow some short-day or slightly shade-tolerant flowers. For example, azaleas, camellias, and Christmas cactus.

   3. West balcony with half-day sun:

   A west-facing balcony only gets sun in the afternoon, and in hot summer it is also prone to scorching. Therefore, you can grow some climbing plants on a west balcony, which not only provide shade but also coolness. For example, wisteria, morning glory, and cypress vine.

   4. North balcony, living rooms with good indoor diffused light, and so on:

   A north-facing balcony rarely sees the sun, so just grow some shade-tolerant flowers. For example, asparagus fern, split-leaf philodendron, and Japanese evergreen.

   How to tell if it is short of water

   If you want the flowers at home to grow well, watering is key. How to judge whether the flowers at home should be watered is also a very important aspect.

   1. Visual method

   The editor of Huinong Network thinks the simplest method is the visual method. Look at the color of the potting soil with your eyes. If it is gray-white, then it is time to water; if the soil is dark brown, it basically means the potting soil is still moist and does not need watering for now.

   2. Lifting the pot method

   There is also a very simple way to judge, which is the lifting the pot method. Lift up the flower pot. If it feels much lighter, then it is time to water.

   Add something to the water to make flowers grow well

   If you want flowers to grow better, just watering with plain water is definitely not enough. Add something when watering flowers to supplement some nutrients, so the flowers grow better!

   1. Add a little rice-washing water

   The editor of Huinong Network thinks the simplest thing is to add a little rice-washing water. Put the water left after washing rice into a plastic bottle, then leave it in the sun to ferment for a period of time. Open the lid every 3-5 days to let it breathe. After it is fully fermented, just dilute it with water at 1:20 and use it to water flowers.

   2. Add a little fish intestine water

   Fish intestines contain very rich phosphorus and potassium fertilizer. Fermenting fish intestines into fertilizer is very nutrient-rich for flowers that bloom abundantly and have long flowering periods, such as roses and bougainvillea. Put the bought fish intestines into a plastic bottle, add some water, and leave it in the sun to ferment into fertilizer. It can be used in about 2-3 months.

   Add something to the bottom of the pot so flowers do not rot roots

   Sometimes flowers at home die for no reason, and it is because the roots have rotted. So when repotting, add something to the bottom of the pot, and the flowers will not rot roots.

   1. Line the bottom of the pot with loofah sponge

   The loofah fibers in the loofah sponge have very large gaps. Lining the bottom of the flower pot with it gives very good water and air permeability, so the flowers absolutely will not rot roots! In addition, loofah sponge can also be used for raising seedlings, and the effect is also very good!

   2. Line the bottom of the pot with broken bricks and tiles

   If you want flowers not to rot roots, you can also line the bottom of the pot with some broken bricks and tiles. Pick up a brick outside, bring it home and break it into small pieces, then soak them in hot water and leave them in the sun to dry. After they are dried, they can be used to line the bottom of the pot.

   Pruning is very important

   If you want flowers to grow well, pruning is essential. Whether it is pruning spent flowers after blooming or cutting off some weak branches and diseased branches on the stems, it can prevent the flowers from consuming too many nutrients, so the plant grows more robustly.

   1. Prune spent flowers

   2. Prune diseased branches, weak branches, and leggy branches

   Pay attention to pests and diseases

   When growing flowers, you must pay attention to the condition of the leaves and flowers. If symptoms such as black spots or white powder are found on the leaves, it can basically be determined to be pests or diseases. At this time, you can make some homemade insecticides, such as garlic water, chili water, and so on, or sprinkle mosquito coil ash on the surface of the flower pot. Both can kill bugs.

   Make your own small potted plants

   Actually, besides growing flowers, many vegetables and fruits can also be grown into small potted plants.

   1. Vegetable potted plants

   Whether it is carrot, cabbage, onion, or sweet potato and potato, they can all be made into small potted plants. Put the vegetable in a bottle filled with water, and within a week it will sprout and grow.

   2. Fruit potted plants

   The passion fruit, fig, lemon, peach, and so on that we usually eat can all be grown at home!

   3. Potted plants from seeds picked in the wild

   It is autumn now, and fellow flower lovers can also go to the wild to pick up some seeds. Whether it is Buddhist pine, goldenrain tree, wild jujube, or chestnut, bringing them home to grow a small potted plant is all very beautiful!

   Make your own flower pots

   Besides buying flower pots for growing flowers, actually many homemade flower pots are also very beautiful.

   1. Coconut shell flower pot

   Saw a coconut open, then scoop out the coconut meat inside, and after that poke a few small drainage holes in the bottom, and it can be used as a flower pot.

   2. Cloth bag flower pot

    Do not casually throw away leftover burlap bags at home. After filling them with soil, they can be used as flower pots to grow flowers.

   3. Tin bucket flower pot

   A tin bucket at home that already leaks water, after being repainted with paint, becomes a very beautiful retro flower pot.

   4. Basketball as a flower pot

   A broken basketball at home, cut open directly from the middle, planted with flowers and hung up, becomes a very beautiful flower pot.

   The above are the 20 little tips for growing flowers at home compiled by the editor of Huinong Network. Flower-loving friends, take a quick look. Once you learn them, the flowers you plant will definitely stay alive and well!

Finding the Key to Growing Roses from Their Causes of Death

Flower lovers often ask me about the key to growing roses: how to mix soil? How to fertilize? How to spray pesticides? What I want to say is that my own roses do not grow particularly well, far from meeting my expectations, but I can share the key to growing them from the most common causes of rose death, based on my exchanges with flower lovers over these years, the rose pictures I have seen on Weibo, and my less than 2 years of experience with potted roses.

Top 5 Rose Killers:

Top 1: Water——frequent watering, not watering thoroughly, watering by number of days

Why is water the number one killer? Many flower lovers think plants need water, so watering a little every day and spraying a little water from time to time is what they should do for them.

Little do they know, plant roots also need to breathe, and keeping roots moist for a long time makes them prone to rot. Another watering method is also very strange: never watering thoroughly each time, only keeping the upper layer of potting soil moist. This method makes the plant's roots concentrate in the upper half of the pot, and once strong sun comes, they easily lose water rapidly and die. Some beginners, in order not to forget to water, use rigid numbers of days to judge whether watering is needed. At any time, please water according to need, and do not treat roses with a method of once every few days or several times a day.

Solution: Water according to need, water thoroughly when dry, and control your hands.

Top 2: Fertilizer——heavy fertilizer, strong fertilizer

Flower lovers who have read expert growing posts can easily remember the experts' secret to abundant blooming: heavy fertilizer, strong fertilizer.

Little do they know, only healthy, vigorously growing plants can tolerate fertilizer and absorb it, turning fertilizer into the energy for blooming; even less do they know that fertilizer use for potted plants and ground-planted plants cannot be generalized. Chicken manure, sheep manure, and even dog poop have all become the “brain platinum” of roses, and fish intestines, eggs, melon and fruit peels, and small animal carcasses have all become the “little blue pills” of roses, but the “brain platinum” and “little blue pills” did not play their due role at home. Instead, they made the roses all reach paradise early. Before that, you might also harvest endless fungus gnats and white fatty worms.

Solution:For small or weak seedlings, use less fertilizer; for large and strong seedlings, use heavy fertilizer. Be cautious with potted plants, and be more extensive with ground planting. Seedlings within one year should not use raw fertilizer, and should mainly use compound fertilizer. Potted plants should not use raw fertilizer, and should mainly use processed finished organic fertilizer and compound fertilizer. For ground-planted seedlings, in the coldest time of winter (such as late December to early February in Jiangsu and Zhejiang), raw fertilizer can be buried, and at ordinary times combine it with finished organic fertilizer and compound fertilizer. During the growing season, use quick-acting liquid fertilizer and pour it at the roots once every 7-10 days. See the content below for an explanation of fertilizers.

Top 3: Love——afraid they are cold, afraid they are hot

“Afraid it will melt in your mouth, afraid it will fly away in your hand” - this kind of love does not only refer to spoiling children. Many flower lovers also love their roses this way.

Little do they know how much harm an unventilated indoor environment does to roses. Roses are cold-tolerant, and in Beijing they can also overwinter outdoors; roses are heat-tolerant, and last year in Jiangsu and Zhejiang during 2 months of high temperatures exceeding 35 degrees every day, they remained full of life even without shade. Do not move roses indoors in winter to enjoy heating, move them indoors in summer to enjoy air conditioning, move them indoors to avoid rain when it rains, or move them indoors to admire the flowers when they bloom. Just let them grow steadily in the natural environment.

Solution:Give enough sunlight and love them boldly. For enclosed environments, please spare the roses; a melon forced off the vine is not sweet.

Top 4: Pruning——regardless of season, regardless of weather

Experts say roses need heavy pruning.

Little do they know, rose pruning differs for climbers, shrubs, and miniature roses, and differs for winter, after blooming, and late summer. What experienced teachers dislike is not stupid students, but careless students. They only see experts saying “prune,” but do not see clearly in what season they prune. The roses pruned by experts are full of life and bloom like brocade, while our roses after pruning are desolate, at best unable to recover, and at worst dead.

Solution:Prune according to season and by type. In winter, prune climbers mainly for shaping and removing old and weak branches, and shrubs. After blooming in spring and autumn, basically you only need to cut off spent flowers and about 2 nodes of branches below the flowers. Choosing an auspicious day with clear weather for pruning can also effectively avoid infection after pruning. Choose professional garden scissors and spare your nail clippers, craft scissors, and all other scissors, which can also make your roses healthier.

Schematic diagram of winter pruning (Thanks to flower lover AKKLematis for providing the picture). Pruning miniature roses is basically the same as for shrubs.

Top 5: Greed——eyeing what is in the bowl while looking at what is in the pot

Today I saw a poisonous picture in the forum——buy! Tomorrow I saw a beautiful picture in the group——buy! Buy, buy, buy, buy, buy! After buying seedlings, buy soil; after buying soil, buy fertilizer; after buying fertilizer, buy pesticides; after buying pesticides, buy pots, an infinite death loop.

Little do they know the importance of accumulating experience. Most enthusiasts have a desire to collect, and should also have the ability to buy all the varieties they like and bring them home, but have you gone to see whether the varieties you planted three months, half a year, and one year ago are still alive now, and whether they are living well? Perhaps when they bloom, you cannot even remember their names. Many flower lovers plant dozens or hundreds in the first year, in a grand fashion; afterward they disappear without a trace from forums and various flower lover groups, and accidentally become the laughingstock of flower lovers.

Solution: In the first year of planting, beginners should focus on accumulating experience and not be greedy for quantity.

Little suggestions for growing roses

Medium selection: The key is not price, but that different media require different management; when the medium is different, fertilizer and water needs are different.

Money-saving version: garden soil, worm castings, leaf mold, other granules

Convenience version (we city people cannot dig up soil): peat, leaf mold, coconut coir, other granules

Wealthy version: various specially formulated ready-made media

Fertilizer selection: The key is not how much, but ease of use and suitability for growth

Raw fertilizer: fish intestines, animal and plant carcasses, and so on

Finished organic fertilizer: processed chicken manure fertilizer, sheep manure fertilizer, worm castings, and so on

Compound fertilizer: Osmocote, Miracle-Gro, Huaduoduo, and other fertilizers with balanced nutrition, suitable for different seasons and different growth periods

Pest and disease control: When pests and diseases occur, use 1-2 times per week; when there is no disease or disaster, it can be used once every ten days to half a month for prevention. When fungal infection is severe, multiple chemicals can be sprayed in rotation. Spray after sunset or before sunrise; avoid spraying and then exposing to strong sun, or spraying under strong sun.

Black spot (fungal): DuPont Fuxing, tebuconazole, Xiangshan sterilization king, and so on

Powdery mildew (fungal): tetraconazole, mancozeb, thiophanate-methyl, propineb, and so on

Spider mites (pest category): cyflumetofen, Jinmanzhi, abamectin, abamectin + pyridaben

Other pests (aphids, small green caterpillars, etc.): Huhuashen, abamectin, imidacloprid, etc.

==================Gorgeous second divider=============

Summing up the above in 16 characters: ample sunlight, good ventilation, water when dry and let dry between waterings, apply light fertilizer frequently.

There is one more secret that I don't usually tell people: fertilize before rain, spray after rain (sterilize first, then kill pests)
