Three essential fertilizers for growing azaleas, applying them at the right time will make the leaves lush and the blooming period will be abundant
Azaleas are very good as potted plants for the New Year. They usually come onto the market in large quantities in autumn and winter, and many people will buy them. However, it is easy to encounter problems when growing azaleas at home, such as yellowing leaves, weak growth, and no flowering. In fact, if you want azaleas to bloom every year and grow well, you just need to fertilize them properly. So, how should you choose fertilizers for azaleas at home? Today, I will tell you about the three essential fertilizers for azaleas. If you use these three fertilizers regularly according to their schedule, the leaves will always be in a lush and green state, and it will be easy to have a blooming period.
1. Growth fertilizer
Azaleas have a growing season. After flowering in autumn and winter, they will enter a stage of growing new buds and leaves. How should we choose fertilizers at this time? We should try to use balanced fertilizers, with nitrogen promoting growth, phosphorus promoting flowering, and potassium promoting root development. We just need to use a multi-element nutrient solution or multi-element compound fertilizer regularly and in the right amount, without too high a concentration. This way, the well-nourished azaleas will grow roots quickly, and with a good root system, they will absorb nutrients and grow enough branches and leaves. The more new buds, the more flowers will bloom.
2. Flower promoting fertilizer
Azaleas usually bloom in autumn and winter. Their flower bud differentiation usually occurs after the spring growth is complete, and by summer, their flower buds will start to grow. Most of the flower buds will fully emerge in autumn. Therefore, we need to supplement phosphorus and potassium fertilizers during the flowering period. We can use monopotassium phosphate or "Flower More No. 2". Phosphorus can effectively promote flowering. Generally, by summer, when they stop growing, we still need to ensure fertilization, but not too frequently, just once or twice a month, and not too high in concentration. Water it into the potting soil during watering. In summer, when the growth is slow or stops, the flowers will differentiate from the top after watering. Continue using phosphorus and potassium fertilizers until the flowers are about to open, then stop and switch to a multi-element fertilizer to promote rapid growth after flowering.
3. Green leaf fertilizer
Many people find that azaleas easily develop yellowing new leaves. Initially, the new leaves turn yellow while the veins remain green, and the yellowing gradually spreads to the entire plant. This is because azaleas are a type of flower from the south that prefers acidic soil. If the water or soil is alkaline, it can cause the new leaves to turn yellow. In this case, during the maintenance process, whether for growth or flowering, we need to use a fertilizer called ferrous sulfate. Ferrous sulfate can adjust the soil to be acidic and supplement iron for azaleas. Azaleas can only absorb enough iron in acidic soil, and with sufficient iron, the leaves will not turn yellow. Ferrous sulfate should be diluted in water at a concentration of 1:1000, then add some vinegar, and apply it to the potting soil once a month. This will allow rapid absorption of iron, keeping the soil acidic, and yellowing will not occur.
If you want to grow azaleas well, these three fertilizers are essential. Ensure the soil is acidic, prevent iron deficiency, and avoid yellowing leaves. Use multi-element fertilizers during the growing season to promote balanced growth, producing enough new buds and leaves. When growth slows down or stops in summer, supplement with high-phosphorus fertilizers to promote flower bud differentiation and growth. By autumn and winter, they will be able to bloom. Choose the right fertilizers, use well-draining soil, avoid large pots, water promptly when the soil surface is dry, and provide some scattered light without direct sunlight. You will not have any problems growing azaleas at home.
