Potted trees can improve the appeal of our house and our surrounding can be made aesthetically more pleasing. There are many types of bonsai trees and we should choose the most appropriate types. Bonsai come in different species of plant and they may require intricate procedure to maintain. We will need to consider correct positioning, light intensity, fertilizer, soil type and water. It is imperative that we are able to maintain bonsai, so they will continue to flourish and thrive in our house.
- Water: Like any plant, bonsai also requires enough water and we should consider the proper amount that we should give. The amount of water could depend on the size of water and the type of plant. The prevailing weather condition could also determine the amount of water.
- Soil: Bonsai plants need the right type of soil. Bonsai stores often offer pre-mixed soil for bonsai, which is essential if our local soil condition is unsuitable for potting. There are different types of soil depending on the plant species. Soil for bonsai is consisted of three primary components, fine gravel, compost and adakama. Adakama is a special clay soil that works very well for bonsai. Alternatively, we could choose local hard clay soil. Often, good composition for bonsai plant is 10 percent compost, 30 percent gravel and 60 percent adakama. We may also change the composition of soil depending on the local situation. If we are living in wet areas, higher percentage of grit and adakama should improve the drainage property of the soil.
- Fertilizer: Trees need enough nutrients to thrive and roots expand to get more nutrients. As bonsai grows, the amount of nutrient inside the pot will be gradually reduced. In this case, proper application of fertilizer should restore the nutrient level. In this case, we should consider the ideal potassium, phosphorus and nitrogen composition. During spring, nitrogen should be ideal for proper growth. Balance mix of nutrients should be great during summer. When plants are preparing for winter, it should get less nitrogen.
- Repotting: Eventually, potted plants need to have fresh new home. Loose, nutrient-rich soil will help to rejuvenate the plant. Without repotting, some bonsai plants will slowly die due to starvation. Some young, fast growing bonsai needs to undergo this process at least once a year. Some bigger bonsai plants can be repotted after 5 years. If we start to see some of the roots jutting out of the soil, then the plant is seeking a fresh nutrient.
- Pest and diseases: Like any living organism, bonsai trees can be affected by other living organisms, in the form of microorganisms and pests. If the problem isn’t addressed quickly enough, the tree could eventually die. Signs of diseases and pest problems are yellow leaves that start to fall off. However, this is also a sign for feeding and watering problem. So, it is important for us to properly check the actual problems. Look for insects like weevils, mites, wasps, aphids, slugs, ants, bees and grasshoppers. Bacteria and fungi could also cause problems.
