Flowers that cannot be killed by heat must be grown during the dog days of summer. The hotter it is, the more vigorously they bloom!

Sunflower

Temperature limit: High temperature 40°C

As the name suggests, sunflowers bloom in the sun and are famous for not being afraid of the sun or heat. Many flower lovers in the south plant them in a circle on rooftops, building roofs, and balconies, and the flowers can be seen from May to November.

1. Reproduction: sowing and cutting

Seed sowing is usually carried out in spring. Now you can use cuttings. Pinch a few finger-long flower branches, insert them 2 cm deep into the soil, water them thoroughly, and place them in the shade. After a day or two, when the branches become firm, they will be ready. Expose them to the sun in the morning and evening, and after a week, they can be exposed to the sun all day. If the cuttings survive, they will bloom after a while, and they will produce seeds after blooming. You can keep them and plant them next year!

2. Maintenance

Sunflowers are quite drought-resistant, but if you keep them under the sun, the evaporation will be high. It is best to water them thoroughly once every morning or evening. Mix fermented rice water or fruit peel water with 5 times the amount of clean water and you can use it as nitrogen and phosphorus fertilizers. No special fertilizer is needed. After cutting off the long branches, you can directly plant them.

Summer Chrysanthemum

Temperature limit: High temperature 40°C

Unlike other chrysanthemums that bloom in spring and autumn, summer chrysanthemums bloom from May to September. Once they bloom, they burst into a ball. The pyrethroid smell they emit can repel mosquitoes, making it an important raw material for mosquito coils!

1. Reproduction: Cutting

Summer chrysanthemum is a new variety with strong reproduction ability. Flower lovers can even make it take root by leaf cuttings! You can plant more summer chrysanthemum stems and leaves, mix perlite with breathable soil, place them in a cool place, water them thoroughly once, spray them with water every morning and evening to keep them moist, and they will take root in about a week.

2. Maintenance

Although summer chrysanthemums are not afraid of heat, they will easily fade if the light is too strong, so it is best to block the light at noon. You don't need to water it too often. You can spray water around it every day to keep it moist. Add phosphorus and potassium fertilizers every half a month. You can use fermented soybean water or dried banana peels.

Platycodon grandiflorum

Temperature limit: High temperature 40°C

Even though Platycodon grandiflorum is used for flower arrangement, it is actually not delicate at all. Some flower lovers who have raised it said that even if the weeds in the pot are dried up, it is still blooming... You will find out how heat-resistant it is only when you try it!

1. Reproduction: sowing, cutting

Platycodon grandiflorum can produce thousands of seeds every year and can be sown in spring and autumn. In the summer, you can buy a few branches of Platycodon grandiflorum and keep them for appreciation. You can cut the extra branches and use them for cuttings. Each branch should have a pair of leaves and be inserted into sterilized sandy soil. After watering, place them in a cool and ventilated place and spray them with water occasionally to keep them moist. They will take root in about a week.

2. Maintenance

Lisianthus can be considered a lazy flower. It should be planted in nutrient-rich leaf mold combined with nutrient soil and gravel. Water it when the soil is dry to avoid suffocating the roots. Spray water in the morning and evening to keep the moisture and cool down. After the flowers bloom, be sure to collect the seeds and then heavily prune so that you can have twice as many flowers next year!

Golden Dew Flower

Temperature limit: High temperature 40°C

Golden dew flower is also called false forsythia. It is mostly grown in the southern regions. It is not afraid of heat or cold, and can bloom in summer, autumn and winter. Flower lovers in the north can also try it.

1. Reproduction: Cutting

Golden dew flower is very resistant to pruning, and the pruned branches can be directly used for cuttings with a high survival rate. Cut them into 8-15 cm long branches, insert them in sandy soil, water them thoroughly and place them in a shaded place. They will take root in about 2 weeks. Just keep it moisturized and ventilated during this period.

2. Maintenance

Golden dewflower loves sunlight. The more it is exposed to the sun, the brighter its color becomes. It is very suitable for planting in the garden and can also be grown as a vine flower. It is best to water once a day in summer, prune slightly after each flowering, and add nitrogen and phosphorus fertilizers. The kitchen waste and leftover fruit peels at home can also be added to the potting soil as fertilizer after fermentation.

Dahlia

Temperature limit: High temperature 38°C

Summer is the flowering season of dahlias. Not only can it bloom throughout the summer, but as long as it is properly maintained, it can even bloom until November in southern regions!

1. Reproduction: root division, cuttings

The bulbs of dahlias are like sweet potatoes. When winter is approaching in the north, they can be dug out and buried in the sand to spend the winter, and then divided and planted in spring. Now we can cut branches and cut them. 10 cm branches can survive in ordinary garden soil. Be sure to pay attention to moisturizing, and place them in the shade and they will take root quickly.

2. Maintenance

Dahlias like fertile sandy soil. They can be planted in a mixture of leaf mold and sand. Do not water them too much. Water them once every 1-2 days and spray water around them to keep them moist. Add compound fertilizer, nitrogen and phosphorus fertilizer before and after the flowering period. Fermented rice water or soybean water can also be added to water for watering.

Catharanthus roseus

Temperature limit: High temperature 38°C

Catharanthus roseus has beautiful flowers, is cheap, and can be grown for more than ten years to become an old tree. Isn't it very cost-effective?

1. Reproduction: sowing, cutting

Seed sowing is slow, but direct cuttings will bloom next month. Cut off young and strong branches, preferably with terminal buds, insert them in vermiculite soil, place them in a cool place, water them thoroughly at one time, then spray them with water every morning and evening to keep them moist. They will take root in about 1-2 weeks, and then change the pot after 1 week.

2. Maintenance

Catharanthus roseus likes sunlight, so it must be placed in a sunny place. Water it when the soil is dry. You can use a spray bottle to spray water around it in the morning and evening. You can also add some potassium dihydrogen phosphate to spray it, which can make it bloom faster and more.

Fragrant vine

Temperature limit: High temperature 36°C

The vine is native to tropical America. It is naturally heat-resistant, good at climbing, and has large and fragrant flowers. Flower lovers who like it should not miss the good season to grow the vine.

1. Reproduction: Cutting

Cut the annual strong branches of the fragrant vine to 5-8 cm long, with a pair of leaves on the top, insert them in vermiculite or granular soil, water them thoroughly, and place them in a ventilated and cool place for maintenance. Keep the soil in the pot moist during this period, but do not allow water to accumulate. It will take about 2-3 weeks for roots to grow.

2. Maintenance

Fragrant vine likes fertile acidic soil, leaf mold mixed with sandy soil and garden soil is good. It should be exposed to more sunlight, sprayed with water every day to keep it moist, and watered thoroughly once every 1-2 days. The frame should be set up during the seedling stage so that it can grow faster. Fertilization is mainly based on nitrogen and phosphorus fertilizers. Potassium dihydrogen phosphate and fermented rice water can be used for watering.

Dianthus

Temperature limit: High temperature 36°C

Dianthus is also famous for not being afraid of heat. The dianthus in many flower lovers’ homes has already bloomed. It blooms for more than just one season. For example, the summer dianthus blooms from April to November!

1. Reproduction: sowing, cutting

Dianthus cuttings are much faster than sowing. It is best to choose branches with flower buds, about 8 cm long, and insert them in moist sandy soil. Place them on a ventilated windowsill and spray some water every day. It will take about 1-2 weeks for them to take root. After the roots have taken root and stabilized for 1 week, change the pot again.

2. Maintenance

Dianthus does not have high soil requirements and can be grown in ordinary garden soil. If you want more flowers, you must get more sunlight, control the water appropriately, and add some urea before and after the flowering period, and you can easily grow a pot full of flowers~
