Can Huaduo be sprayed on orchids?
Sharing content about orchids, a type of orchidaceous plant. Can Huaduo be sprayed on orchids? Let's delve into the details below.
Some orchid enthusiasts have asked if Huaduo can be sprayed on orchids. There are many types of Huaduo, with Huaduo No. 1 and No. 2 being the most common. Huaduo No. 1 is a general-purpose fertilizer with balanced nitrogen, phosphorus, and potassium, while No. 2 mainly promotes flowering, with higher phosphorus and potassium content. However, orchids are oligotrophic plants, meaning they do not require a large amount of fertilizer. Even if the nutrient supply is insufficient, it will not cause fatal damage to the orchid plants, nor will it significantly affect their growth and development. However, excessive fertilization or improper fertilizer management can have varying degrees of negative effects on orchid plants, potentially leading to death.
So when orchid enthusiasts ask if Huaduo can be sprayed on orchids, it's important to note that we should not rush. If you want to fertilize orchids, it is essential to use a light fertilizer with a very low concentration. When combining this with regular spraying to increase humidity, a small amount of light fertilizer can be补充ed every 7 days or so. There is no need to fertilize as frequently as with other plants.
Although orchids do not require much fertilizer, it does not mean they cannot be fertilized. This mainly depends on whether we can control the concentration and frequency to avoid fertilizer burn.
1. Germination Period: The temperature range of 8-18 degrees Celsius in spring is the germination temperature for orchid plants. During this period, the orchid roots revive, the rhizome wakes up, and the mother cells become active. After spraying Huabao No. 4 twice to promote germination, add Lan Jun Wang to the water to aid in sprouting. There are no visible signs of growth on the orchid plants during this period. Weak seedlings should be allowed to continue to rest and should not be fertilized yet.
2. Growth Period: The temperature range of 12-20 degrees Celsius is the normal growth temperature for orchid plants. During this period, the orchid roots begin to stretch, last year's autumn buds break through the soil, and new buds are eager to grow, making it the golden period for orchid growth and development. Attention should be paid to the water and fertilizer management of orchid plants. A balanced fertilizer is recommended, or a nitrogen-rich fertilizer can be used. Avoid excessive nitrogen, as it can easily cause new seedlings to have soft, thin, and large leaves, making them prone to carbon disease. During this period, fertilizing can be done at normal proportions to promote strong buds and seedlings, which is the first application of fertilizer.
3. Spring and Summer Vigorous Growth Period: The temperature range of 20-32 degrees Celsius is the period of vigorous growth for orchid plants, coinciding with the plum rain season. During this period, orchid plants grow rapidly, and although they require a large amount of nutrients, the previous root fertilizers still have varying amounts remaining in the pot (with less or no coarse material left, fertilization should still continue). Therefore, the root fertilizer used at this time must be light to reduce the risk of fertilizer burn due to rising temperatures. Phosphorus and potassium fertilizers are recommended, or a balanced fertilizer can be used, with little or no nitrogen. This period is also a high incidence of diseases and pests, so it is important to enhance ventilation and water control and take good pest and disease control measures.
4. Stagnation Period: This refers to the short period of stagnation in orchid plants at temperatures above 35 degrees Celsius, but there are not many hours in a day with temperatures above 35 degrees. In fact, orchid plants grow most vigorously at high temperatures and are most susceptible to soft rot and stem rot. To prevent rot, along with some fertilizer residue from previous applications or the inherent肥性 of the planting material, during the three伏 days, it is essential to increase the amount of watering and not to fertilize. Each time, water thoroughly 2-3 times to carry away the remaining fertilizer in the pot, repeating this process 3-4 times to make the potting mix light and moderate, which is an important measure for orchid plants to safely survive the summer.
5. Autumn Vigorous Growth Period: The temperature range of 32-20 degrees Celsius is the period of vigorous growth for orchid plants in autumn. Since we have diluted the potting mix in summer, and the orchid plants require a large amount of nutrients at this time, it is necessary to apply root fertilizers (the second deliberate application) with a focus on phosphorus and potassium.
6. Dormancy Period: Below 8 degrees Celsius, orchid plants basically stop growing and enter dormancy. At this time, foliar fertilizers can be applied appropriately.
