If you don't know these tricks when growing flowers in summer, your flowers will surely die.

Rose

After the flowering period in May, we will enter the hot and rainy summer, and the roses will soon enter a dormant and semi-dormant state. For roses, the focus of summer care is to make the plants that have bloomed grow strong and enable them to bloom again as soon as possible.

1. Shade and Cool

There is limited soil for potted roses, and hot weather can easily dry out the soil, so the roses must be shaded to cool them down. Today Huahua will introduce to you several methods of shading so that the roses in your home can receive scattered light.

1. Use a shade net or straw mat to cover the roses in a semi-shaded state, forming a shadow on the ground, which can achieve the purpose of cooling down.

2. You can put another large flowerpot outside the rose pot, and add some pumice, expanded clay and other things between the bottom of the large flowerpot and the gap between the two flowerpots, which can also help to cool down.

2. Watering and fertilizing

Due to the high temperature in summer, roses gradually enter a dormant period. However, roses still bloom in summer, so they also need to be fertilized, but the amount of fertilizer should be less than in spring and autumn.

1. In the summer, you can apply a thin layer of liquid fertilizer every 15 days or so. The liquid fertilizer can be made from moldy soybeans or animal manure, which is formed after soaking in water, sealing and fermenting. The concentration should be above 1:50, which can meet the growth needs of roses.

2. In summer, the evaporation is high, so you can water the plants every 2-4 days. It is best to use water for watering roses after drying it in the sun. This can reduce the temperature difference between the potting soil and the water. If too cold water is used, it will stimulate the rose roots and affect the normal development of the plant.

3. In addition to watering the roses normally, you should also spray water on the leaves more often. It is best to spray once in the morning and once in the afternoon, before 8 o'clock and after 5 o'clock in the evening. You can also add some 0.2% potassium dihydrogen phosphate solution when spraying water, which can make the roses bigger and more colorful.

3. Pest control and disease treatment

Summer is the peak season for rose diseases. Leaf spot, scale insects, powdery mildew, etc. all occur in summer.

1. When the weather is hot, the ground where the rose pots are placed should be sprayed frequently with 15% quicklime or carbendazim or potassium permanganate solution to achieve sterilization and disinfection and prevent the invasion of pests and diseases.

2. If you have found that the rose has powdery mildew and leaf spot, you can spray it with 0.3% lime sulfur mixture once a week, and it will be fine after about 2-3 times. If you find small insects, you can immediately spray 800 times of DiBiSi to kill the insect eggs.

Geranium

With the arrival of summer, whether geraniums can survive the summer safely is a question that many flower lovers are very concerned about. As long as you follow Huahua and do these things, your geraniums can safely spend the summer.

1. Shade and ventilation

The summer temperature is high and the weather is hot and humid. If the air is not circulated, it is likely to cause the geranium to die.

1. In summer, you can add some covering materials on the geranium's potting soil to reduce water evaporation and avoid direct sunlight causing the soil temperature to rise. It can also isolate the bacteria on the surface of the potting soil. Orchid stone and expanded clay are both fine. Do not choose tree bark that is prone to insects and non-breathable stones.

2. Geraniums need proper shade in the summer. They can be exposed to the sun in the morning and evening. At noon, they should be moved to a place with scattered light. If placed near the window, you can pull down the curtains or add a sunshade net.

2. Watering and fertilizing

Watering geraniums in summer is the most troublesome thing.

1. The best time to water is in the morning or evening, and wait until the soil temperature drops before watering. The water should be left to dry for a while so that the water temperature can be similar to the room temperature.

2. There are many ways to water. Don't water from the top of the pot. This can easily result in water on the top of the pot while the roots at the bottom of the pot do not absorb the water, leading to death. You can use the pot-sitting method to water to ensure the geranium's need for water.

3. Do not apply fertilizer to geraniums in summer, because geraniums in dormancy cannot absorb fertilizer at all, and fertilizer accumulation may cause root rot.

3. Pests and diseases

Geraniums are particularly susceptible to diseases and pests in summer, so preventive measures need to be taken in advance.

1. In order to prevent geraniums from getting stem rot, you can irrigate the roots once a month with carbendazim solution, root rot solution or potassium permanganate solution to prevent bacterial infection. If you find that your geranium has stem rot, you will have to discard the seedlings and the soil.

2. If you find leaf spot disease, flower wilt disease, etc. on geraniums, remove the diseased leaves in time to prevent the spread of infection, and then spray Bordeaux liquid for prevention and control.

Clivia

Clivia is basically in a dormant state in summer. In order to allow Clivia to spend the summer safely, Huahua has found a few points that you must pay attention to. Flower lovers must remember them.

1. Shade and ventilation

In the summer, the temperature is high and Clivia is in a semi-dormant state, so we must do a good job of preventing heatstroke and cooling down.

1. Clivia likes weak light but not strong light, and is most afraid of direct sunlight. Therefore, it must be placed in a cool and ventilated place in summer so that it can see scattered light in the morning and evening.

2. You can use the method of burying sand to cool down. That is to bury the Clivia and the pot in the sand, making sure the pot is completely buried, and then spray water on the sand every morning and evening. Doing this can not only keep the soil in the pot moist, but also achieve the purpose of cooling by taking advantage of the heat absorption of the sand when the water evaporates.

2. Watering and fertilizing

Watering of Clivia is also very important.

1. The temperature is high in summer and the evaporation is relatively large, so the water demand of Clivia is also relatively large. For 1-2 year old Clivia, water it about once every 5-7 days; for Clivia over 3 years old, the watering time also depends on the size of the flowerpot and the age of the Clivia.

2. It is best to use stored rainwater to water Clivia. Tap water can only be used after it has settled for 24 hours to prevent soil deterioration. If the soil in the pot does not drain well and water accumulates for too long, it can easily cause the fleshy roots of the Clivia to rot.

3. In hot and rainy summer, you should stop fertilizing to avoid root rot. If the Clivia is placed in a cool and ventilated place, it will not completely dormant. At this time, you can apply a thin bean cake liquid fertilizer once every 10-15 days. Keep the potting soil dry before fertilizing.

3. Pests and diseases

Since Clivia is in a dormant period in summer and ventilation is poor, it is particularly vulnerable to scale insects. At this time, you can use drugs such as Acarid or DDT. Mix them with water in a ratio of 1:2000, spray them on the leaves of Clivia, and irrigate the roots at the same time, which can effectively kill scale insects and other pests.

Kalanchoe

As summer approaches, the temperature has been rising. How to care for Kalanchoe in hot weather? Huahua will give you a detailed introduction.

1. Shade and Cool

In the hot summer, Kalanchoe is basically in a dormant state. At this time, its resistance is relatively poor and it needs proper shade and cooling.

1. In order to lower the temperature, you can spray more water on the ground so that the water can evaporate and take away some heat. You can also spray water on the leaves to lower the temperature around the Kalanchoe. When spraying water, be careful not to spray too much, otherwise it will easily cause the Kalanchoe to rot.

2. In order to avoid strong light burning the leaves of Kalanchoe, shade is needed in summer. You can add a shade net or move the Kalanchoe to a place with weaker light.

2. Watering and fertilizing

When the Kalanchoe is in its dormant period in summer, you should pay attention to water control. Water control means reducing watering, but it cannot stop watering, otherwise long-term drought will easily lead to root death due to lack of water.

1. For those who grow Kalanchoe indoors, water it about once every 10-15 days and keep the soil slightly moist. If you water too much, the fleshy roots of the Kalanchoe will easily rot. For outdoor Kalanchoe, a little rain is fine, but when it rains heavily, they must be moved indoors in time.

2. When fertilizing Kalanchoe in summer, the concentration should be low. Basically, thin liquid fertilizer can meet its growth needs. It should be applied about once every 8-10 days. You can use decomposed bean cake fertilizer or Chinese medicine residue.

That’s all for today’s introduction.
