Camellias, azaleas, phalaenopsis orchids and other flowers like these have always been popular, and they are also recognized as hard to grow! Even if you care for them as carefully as you would a child, they still up and die on you. Below, Huahua will teach you some tips for getting them through summer!
How do you care for camellias in summer?
G a r d e n i n g E n c y c l o p e d i a
The peak blooming period of camellias has passed, but if you want them to burst into bloom again, summer care and management are key.
1. Post-bloom pruning
Be sure to remove any remaining spent flowers, and prune over-dense tangled branches, crossing branches, and dead or diseased branches, to improve the plant's ventilation and airflow while reducing nutrient consumption, preparing for the next round of blooming!
When pruning, cut branches diagonally downward, keep the cut edge flat, use sharp scissors, and a smooth wound heals more easily.
2. Summer watering
Camellias like a warm, humid, slightly acidic environment. In summer, water every morning and mist around the plant to maintain higher air humidity. On rainy days, promptly pour off any standing water in the pot.
Gardeners in the north should note: first let tap water sit for 2 days to let the chlorine evaporate before using it to water flowers; you can also add a few drops of ferrous sulfate solution to the tap water, acidify it, and then water the flowers.
3. Summer lighting
Camellias like light but are averse to being scorched, as they are semi-shade plants. When grown outdoors, provide appropriate shade; when grown indoors, place them in a spot with bright, indirect light, and make sure there is ventilation.
4. Summer fertilizing
Camellias like fertilizer. In summer, apply decomposed liquid fertilizer or compound fertilizer about once every half month.
5. Summer pest and disease prevention
In summer, camellias are prone to leaf spot disease, damping-off disease, etc. You can use a 50% carbendazim 1000-times solution to spray the plant or drench the roots for prevention and control. When pest problems are severe, spray a 50% omethoate 1000-times solution about once every 10 days for control.
How do you care for azaleas in summer?
G a r d e n i n g E n c y c l o p e d i a
Post-bloom pruning
1. After blooming, first cut off the spent flowers to save nutrients; for overly dense branches and dead or weak branches, also remove them promptly to regulate growth and development while increasing ventilation and light penetration;
2. When diseased branches are found, remove them promptly to reduce the spread and infection of pests and diseases.
2. Summer watering
In summer, water transpires quickly, so water once before 10 a.m. and once after 4 p.m. each day, watering thoroughly once the soil is dry, keeping the potting soil moist but not waterlogged, and never water flowers with alkaline water.
3. Summer lighting
Azaleas like a cool, well-ventilated, semi-shaded environment, and are afraid of heat and scorching sun. In summer, provide appropriate shade, or place them on a bright windowsill indoors.
4. Summer fertilizing
After azaleas bloom, new leaves sprout and branches extend, so you can apply a diluted nitrogen fertilizer about once every 15 days, but when summer temperatures are too high and the plant grows slowly or enters dormancy, stop fertilizing at that time.
5. Summer pest and disease prevention
In summer, azaleas are prone to iron-deficiency chlorosis, leaf blight, black spot disease, etc. After discovering a pathogen infection, promptly cut off the diseased plant, disinfect with a diluted 500-times to 1000-times potassium permanganate solution or carbendazim, then rinse with clean water and repot with fresh soil.
How do you care for phalaenopsis orchids in summer?
G a r d e n i n g E n c y c l o p e d i a
1. Post-bloom pruning
After phalaenopsis orchids enter June, the peak blooming period is over. At this time they must be pruned, otherwise the next round of blooming will be affected.
Cut the flower stalk at the 4th to 5th node from the base, and it can bloom again after 2 to 3 months; if you want even better blooming next year, it is best to cut off the flower stalk entirely.
2. Summer watering
In summer, water evaporates relatively quickly, so water once each morning and evening, watering thoroughly once the soil is dry, keeping the soil slightly moist, and check the root system at intervals to prevent root rot from too much water; after entering dormancy, reduce watering.
3. Summer lighting
Phalaenopsis orchids like shade and ventilation, and dislike muggy heat. In summer, provide 50% to 70% shade outdoors, and place them in a spot with indirect light indoors.
4. Summer fertilizing
During the growing period, apply compound fertilizer once a week; alternating nitrogen fertilizer and potassium dihydrogen phosphate also works. When growth slows at high temperatures, stop fertilizing.
5. Summer pest and disease prevention
Soft rot is the number one killer of phalaenopsis orchids in summer, generally occurring on the stems and leaves. Once discovered, promptly isolate the affected area, cut off the rotted leaves or stems, and apply fungicides such as thiophanate-methyl or carbendazim, then place the diseased orchid in isolation in a ventilated spot for care.
How do you care for Rieger begonias in summer?
G a r d e n i n g E n c y c l o p e d i a
1. Post-bloom pruning
After the peak blooming period in June, prune the spent flower branches to save nutrients and make the next round of blooming better.
Cut off overly dense and thin branches to thin them out for ventilation while reducing viral infection.
2. Summer watering
When summer temperatures are high, growth slows, so control watering. If standing water appears in the pot, remove it promptly to prevent root rot and black rot.
3. Summer lighting
Rieger begonias are short-day plants. In summer, provide shade and just place them on a cool, ventilated windowsill.
4. Pest and disease control
Rieger begonias grown at home have relatively few pests and diseases. Regularly spray fungicide to prevent soft rot and powdery mildew; a 1000-times carbendazim solution can be used for spraying.
