Why does the plumbago smell so bad?If you want to learn about why plumbago smells so bad and the cultivation methods of green plants and flowers, here is the specific content:Summer is very suitable for planting plumbago, as the flowers are large and come in a variety of colors, the main advantage being that they are not afraid of direct sunlight.There is a kind of flowering plant that is like a god-like existence. During the blooming period, it can produce flowers similar to peonies, and what's most important is that the flowers come in many colors. Not only can it be planted in the garden for decoration, but once mature, the flowers can be cut and given to loved ones. It is the star of our introduction today: plumbago.Plumbago is a perennial herbaceous plant. Generally speaking, the number of flowers is relatively small in the first year after planting, and by the second year, many flower buds can grow on the branches, with the most crucial aspect being that the flowers are very large. Some special varieties can produce petals of different colors on the same plant. What I like most about it is that it can still bloom beautiful flowers in the hot summer.The planting method of plumbago is simple. First, prepare fertile soil. The soil must be specially configured and cannot be used directly as garden soil. Since its root system is not very developed, a small pot is enough. The pot needs to be filled with decomposed soil, pine needle soil, sandy soil, and wood ash. Once these four substances are mixed well, half of the planting process of plumbago is successful.If you want it to grow well, it is best to put some organic fertilizer at the bottom of the pot when preparing the soil. In the summer, I recommend using processed organic fertilizer, as the rising temperature can produce a strong unpleasant smell. You can also prepare dried orange peel and place it together with organic fertilizer at the bottom of the pot to reduce the smell to some extent.Why does plumbago smell so bad?After the soil is prepared, carefully plant the plumbago seedlings in it. The roots should not be buried too deep in the soil, just enough to ensure that the seedlings do not fall over, because after a period of time, the stems will grow and tightly grip the soil.The next step is watering. Plumbago does not like a lot of water, especially when the soil is waterlogged and very loose, which can easily lead to disease. Only when the soil is kept in a semi-dry and semi-wet state will it grow well. Each time you water, pour the water slowly along the side of the pot so that the soil is evenly and completely wetted.In addition to watering, fertilizing is also essential. Usually, I like to use ternary slow-release fertilizer for it, which has sufficient fertility and comprehensive nutrition, and most importantly, it does less harm to the plant's roots. Therefore, this fertilizer is very suitable for plumbago. In addition to the above aspects, it also needs some sunlight.I think if you don't have any plants to plant in the summer, you might as well raise a pot of plumbago. It has a long blooming period and can accompany you through the hot summer.The above content about why plumbago smells so bad and the cultivation methods of plumbago flowers are provided for your reference.
