It has surprised me to learn that redwood bonsai trees thrive in the right growing conditions. Is it possible to grow Redwoods indoors? In both cases, it is highly recommended that you grow your redwood bonsai in the shade. Adding pebbles or stones to your humidity tray will increase humidity and keep your roots from developing root rot. Every other year, a pot of fresh mineral-rich, quick-draining soil can be repotted to provide a quick-drying, nutrient-rich landscape. It was introduced to the area during the dinosaurs and grew as a prolific crop during the thick redwood forests of the ancient past. If you keep your Dawn Redwood bonsai outside, you will notice the heartiness that comes from the natural beauty of fresh air and sunlight. Dawn Redwoods can reach heights of up to 110 feet with a 25-foot spread. In this case, it is a true Redwood, which is exactly like the American Redwood, and it is stunning as a bonsai specimen. It was discovered in Manchuria, China, in the early 1900s by the Dawn Redwood or Metasequoia glyptostrobides. With proper care, your dawn redwood bonsai will thrive and be a beautiful addition to your home or garden. Protect your tree from extreme temperatures, both hot and cold. Water regularly, making sure the soil is never allowed to dry out completely. Fertilize your dawn redwood bonsai regularly with a balanced fertilizer. Dawn redwoods can be wired, but care must be taken to not damage the delicate bark. ![]() Pruning is necessary to keep the tree compact and to promote new growth. They are fast growers and can quickly outgrow their pot if not properly cared for. Dawn redwoods prefer full sun or partial shade and moist, well-drained soil. Since then, dawn redwoods have been successfully cultivated and are now widely available. They are native to China and were thought to be extinct until a small grove was discovered in the 1940s. Far better to watch the watering.Credit: Dawn Redwood bonsai are beautiful, unique trees that make wonderful bonsai specimens. I wouldn’t wrap anything round it as it simply becomes a large wet pot if you do. I do mine in stints to allow it to soak the compost say 2 or 3 minutes between each stint until it makes a full wet circle under the pot. My 9 ltr airpots usually take between 3 – 4 lts of water at each watering. Depending on the heat mine go two to three days on average before the next watering. Normally if watered correctly they should easily last a day. I always feel the weight and then check the underneath of the pot to see if moist. I never solely rely on the rain to water them as there is so much soil unless it is torrential it won’t reach the bottom and obviously kills those roots. ![]() Another tip is to feel how heavy it is when watered as this will give some indication when watering is required again. With so many roots it’s easy to miss the central core beneath the trunk.as the water tends to run down the edge first. Lift it up and look on the floor, you’ll see if you’ve got an even watering. When watering ensure it runs out of the bottom. You’ll find that it is the central roots that grow down first and once they reach the holes as the bottom, that’s when most of the lateral roots grow and once they strike through the cones they die off and promote finer roots further back. I would recommend using liquid fertiliser every fortnight rather than granular as it promotes faster growth, which is why we use airpots in the first place. This is the water reservoir and the airpot will dry out quicker because of it. You haven’t filled in the cones on the top layer with soil. Hi Grace, I use airpots a lot and here’s my take on the problem. I’m consuming as much Dawn Redwood content and Fundamentals content as I have time for, but I’m still very new (first year doing bonsai!) and the problem is progressing faster than I can figure it out. None of my other trees are behaving like this. I’ve been watering about once a day less when it’s humid since it’s in potting soil. I haven’t fertilized since I noticed the problem, but there’s some still in the pot. ![]() ![]() I’ve been fertilizing with high nitrogen granular fertilizer. More needle tips have gone tan, and there’s a rusty brown color patching across some of the needles too. But over the past couple days the browning has been spreading. I figured this was heat burn, and since the growing tips remained bright green I wasn’t too concerned. It’s been growing aggressively this spring by volume, I think it’s doubled in size every month since May.Īround the time of the awful PNW heat wave, it got brown tips on some of the longer needles. I have a very young Dawn Redwood I’ve been growing for future use. I’m having my first case of “something is wrong and I have no idea what it is”.
