Simply, yes, they do. They require the same amount of sunlight as their full-sized counterparts. So, if you have a bonsai, say, a juniper or pine tree, it will have the same light requirements as a full-sized juniper or pine tree. The same would go for a Thorn Tree or a baobab. They will also have the same temperature requirements as the full-sized versions. Junipers and pines require periods of cold so they can go dormant. A pine or juniper kept indoors for long periods will not receive the light it needs, and it will not experience the cold it needs, and it will eventually die. A baobab or Thorn tree on the other hand do not tolerate cold, and do need to be sheltered, not necessarily brought indoors.
Bonsai need direct sunlight, from which they make their food. A lack of direct sun will damage them, causing weak foliage and other problems. All Bonsai love to be outside in the warmer months (September to April), though there are a few species which can be kept indoors year-round. Remember that the more sunlight and warmth your Bonsai receives, the more often it will need water. That said, you’ve probably heard a few stories about friends accidentally killing them. Often, this occurs because beginners aren’t aware of what this little tree needs to thrive and grow. A little bit of knowledge goes a long way here, especially when looking at the plant’s sunshine needs. Good light is vital for your bonsai’s health. The ultra-violet ray in sunlight affects their growth in a positive way. This means you should try to place your plant in a sunny location – the brighter the better.
How much light does a Bonsai tree need?
They like to receive 5-6 hours of sunlight daily, whether direct or indirect. Some species do better in winter if they get their light from indirect sources. Something to keep in mind is that these plants can burn if they’re taken from a shady place to a sunny position. Rule of thumb is to gradually increase their light exposure.
Keeping your bonsai indoors creates one of the biggest problems that they don’t receive the light intensity they need to grow. They won’t die instantly, but their growth will be limited, and they will weaken.
Bonsai trees do not require direct sunlight in order to grow, as opposed to other trees. In fact, they may even develop in low-light situations. That said, if you want your bonsai tree to reach its full potential, make sure it must be exposed to direct sunlight every day for a minimum of 4 hours.
When to Put Your Bonsai Tree In Sunlight?
For young bonsai, it is important that you do not expose it to the sun for too long, in it’s early stages of growth. Scalding and Sunburnt leaves will be damaged beyond repair and will die and drop off. If you want your bonsai tree to thrive, provide it with direct sunlight for around three hours in the morning when it’s young.
As your bonsai grows, you can increase the amount of sunlight exposure depending on its health. However, be sure to gradually increase the exposure time so you can adapt your bonsai tree in order for it not to suffer from too much sunlight.
Why Do Bonsai Trees Need Sunlight?
The leaves of your bonsai use photosynthesis to make food and use that food for energy. This is vital for the growth and health of your bonsai. It is therefore important that you provide it with some exposure to direct sunlight every day.
If your bonsai tree is growing in its pot indoors or inside a greenhouse, make sure it can’t be affected by overly hot temperatures by placing the container in a spot where it can receive shade.
How Much Sunlight Do Different Types of Bonsai Trees Need?
Different types of bonsai trees need different amounts of sunlight exposure every day. It is important to understand the different species requirements and care instructions and to pay attention the type of tree or plant you have in order to maximise their health.
What Happens if I Expose My Bonsai Tree to Too Much Sunlight?
Exposing your bonsai tree to too much direct sunlight can result in the burning and death of leaves as well as stunted growth. If you’ve been exposing it to direct sunlight for several hours per day and notice its leaves starting to curl up and die, move it towards a location where there’s indirect light.
If that doesn’t work, water your plant with tepid water to reduce the stress caused by overexposure. If the sunlight exposure is only limited to a few hours during the day, then you can just wait for its leaves to heal and grow back again.
However, if you notice that some of your branches are dying off as well due to prolonged exposure to direct sunlight, you can remove it immediately before it spreads. Although bonsai trees are resilient, they still need the right amount of attention and care so they can continue growing healthy and strong.
Is There a Substitute for Sunlight in the Bonsai World?
In the bonsai world, there are no substitutes for sunlight. In order to ensure that your plant gets enough exposure, you have to put it in a location where it can receive indirect light during the day so it can produce energy through photosynthesis.
In conclusion, to ensure you have healthy thriving bonsai, give them sunlight!
