Bonsai Repot - When is the best time to repot your Bonsai

Re-potting your Bonsai - Root pruning is one of the most important things because the roots may start rotting at some point.

Potting is one of the most complicated subjects in bonsai but I can assure you that it's not rocket science and it's just a matter of paying attention. Many newcomers to the hobby make the mistake of putting a tree into a bonsai pot before it's ready. Honestly speaking, re-potting your Bonsai can make a big difference and is practically a must ''do'' if you want to see excellent results. If you are putting a tree into a training pot and are not going to root prune you can slip pot just about anything most of the time. This is simply placing the root ball in another pot which may or may not be larger. Root pruning and re-potting a root-bound plant will refresh it and cause it to put out fresh growth. An other important aspect of pruning is the timing, make sure that the roots are neither too dry or to wet (because the roots can start rotting).

Once again you must know what type of tree you have. Some trees grow so fast they must be root pruned and re-potted yearly. Others may need it every other year or some exceptionally slow growers every 3-5 years. Generally, tropicals are best re-potted and root pruned during the hottest part of the year when they are actively growing. Re-pot most temperate climate woody trees just before bud break or when they first start showing fresh white root growth. Usually this is accomplished in the early spring. Some species can also be re-potted in late fall. When re-potting a finished bonsai, the general practice is to remove one half to two thirds of the old soil and prune one third to one half of the roots. The tree is then replaced in the same pot.

You should prune foliage from the tree when you remove roots. Pruning a comparable amount will save stress on the tree. For example, if you remove 1/3 of the roots, top prune 1/3 of the foliage. It may be easier to prune the foliage while the tree is still in its pot. Have everything you need at hand before you begin, tools, soil, pot, screen and wire. Do not do this in the bright sun light or the roots may dry out. Once the root are dried out, the tree will die and all efforts will be lost. Please bear in mind to chose a good spot to do the work, as this is ab absolute fundamental aspect in the process of re-potting.

Pull the plant out of the pot and attempt to untangle the roots. Some people use a root comb or even a fork will do. The roots should be trimmed all around so the tree will fit back in the container with fresh potting mix. Try to spare as many of the small, fine roots as you can. These smaller roots are more efficient at taking up water that the tree will need after the pruning.

Place a shallow layer of fresh soil in the bottom of the pot and set the root ball on it. Pour more soil around the roots, tamping it into place. Check the soil for air pockets. It can sometimes be hard to get soil to fill all crevices between the roots. One method is to manipulate a chopstick or wooden skewer between the roots to make the soil spill down. If you did not cut back the foliage yet, do so now.

Water the tree thoroughly. This will settle the tree into the new soil. The tree should be anchored in the pot some way so that the wind does not move it around in the soil. The tree should be placed in a semi-shaded location for two weeks. Do not fertilize until you see new growth. There it is, a new look and strong growing Bonsai tree for many years to come.

Deciduous Bonsai Soil Mix

The primary components are Akadama, Pumice and Black Lava. We also added a bit of Horticultural Charcoal and Haydite. These components have been found over time to provide the best drainage, water retention, nutrient retention and air circulation possible to promote healthy bonsai.

- 1/2 Japanese Hard Akadama - is a clay like component that is excellent at retaining water and it breaks down allowing roots to grown in it's place.

- 1/4 Japanese Hyuga Pumice - is a volcanic byproduct that is excellent at retaining water and nutrients.

- 1/4 USA Black Lava Rock - is also a volcanic byproduct that is excellent at retaining moisture. Black lave also adds structure to the soil.

- Horticultural Charcoal -This was added to harbor beneficial bacteria and add humic acid in the soil.

- Haydite - (expanded shale) has the ability to absorb excess water then release it slowly back to the roots.

How Do I Use It?

This is "real" bonsai soil. Be sure your bonsai pot has holes in the bottom covered by bonsai mesh.

Each micro climate may require different amounts of water. On hot days you may need to water two times while around freezing you may need to water every few weeks. Push your finger 1" into the soil and feel for moisture. If it is dry, it is time to water.

Pruning Techniques for Juniper

It's a very fascinating and distinctive tree in comparison to many others. I simply like Junipers due to easy maintenance and romantic look. Interestingly pruning techniques for this type of trees are not rocket science and if you just started with Bonsai, it's a good way to put hands on and try pruning it the best you can. Don't forget, nature is very forgiving so if happen that you accidental prune the wrong way, Junipers will easily forgive you and incredibly recover foliage pretty well.

Junipers, with their many shapes, colors and sizes, are prized in the landscape for a variety of purposes including privacy screens, accents and ground covers with heights upwards of 30 feet and colors ranging from blues to grays and greens to yellows, it's no wonder you can find a juniper in almost any landscape design. Because of their dense foliage, junipers require little pruning to maintain their shape. However, if you feel you must prune, there are a few delicate rules to follow. Not pruning a juniper the correct way can lead to bare spots, uneven shape and disease. Additional, it's very important to sharpen shears and cutters as needed to keep cuts clean and less stressful to the tree.

Look at your juniper for pruning needs in early spring just before the new growth begins; early spring is the best time to prune junipers. Start pruning and shaping while the tree is young and do a small amount each year.

Identify areas you would like to prune back and mark with ribbon individual branches to be cut.
Identify the "dead zone" of your juniper -- the inside of the plant that is full of bare branches and wood. Never cut back to this dead zone or wood that has no needles on it, as junipers will not produce new growth on this type of wood.
Cut individual branches back to a side shoot or leaf of an upward-growing branch, using pruning shears. Cutting to this type of shoot will make the tree look younger and healthier while maintaining a pleasant shape.
Cut any completely dead or broken branches back to the main trunk using loppers, as the juniper is wasting energy on these branches that could be better used to promote new growth and keep the remaining branches healthy.
Avoid cutting your bottom branches shorter than those above them, as tapering in towards the bottom creates too much shade and thus will kill off the bottom. Make sure the base of the juniper is wider than the top.

Please feel free to let your trees grow naturally. I prefer to practice a craft where I get to decide what the tree looks like. Just letting a tree grow naturally is not and will never be bonsai. If you spend time looking at natural trees there is certainly much beauty but very little perfection in terms of bonsai.

Pruning Unruly Junipers

Can you prune an overgrown juniper? Unfortunately, the answer to this question isn’t a definite yes. Juniper trees and bushes have something called a dead zone. This is a space toward the center of the plant that doesn’t produce new leafy growth. As the plant gets bigger and thicker, sunlight is unable to reach its interior, and the leaves in that space fall off. This is completely natural, and actually the sign of a healthy plant. Sadly, it’s bad news for pruning. If you cut back a branch below the leaves and into this dead zone, no new leaves will grow from it. This means that your juniper can never be pruned smaller than the border of its dead zone. If you keep up with pruning and shaping as the tree or shrub grows, you can keep it compact and healthy. But if you try to attempt overgrown juniper pruning, you may discover that you just can’t get the plant down to a size that’s acceptable. If this is the case, the only thing to do is remove the plant and start again with a new one.

While overgrown juniper pruning has its limits, it is possible to trim your plant down to a more manageable shape. One good place to start is the removal of any dead or leafless branches – these can be cut off at the trunk. You can also remove any branches that are overlapping or sticking out too far. This will give the remaining healthy branches more room to fill out. Just remember – if you cut a branch past its leaves, you should cut it off at its base. Otherwise, you’ll be left with a bare patch.

Start a Bonsai from Seed

If you really wish to start a Bonsai from seed, then you must be aware that it can take ages to see first results. Not mentioning about time and effort that must be invested in wiring and shaping the Bonsai. There is no such thing as Bonsai seeds, these are normal trees and you the one in charge to make it happened! You should of course be aware that trees used in Bonsai are not 'special', not genetically different, they are the same trees as you see all around you.

For those that still may wish to grow a tree from seed. This will give you absolute control over the tree from its beginning. The best advice I can give you is don't do it, simply because life is to short.

You may have been the lucky recipient of one of the many Bonsai Kits available, go on and try it! follow the instructions, watch those precious little seeds germinate, poke their heads above the soil, and die. On closer inspection you will probably find the seedling has rotted at about soil level, this is called 'Damping off' and is a fungal attack. You can overcome this by adding a fungicide to the first watering and then as directed by the instructions. Bonsai 'kits' put people off the hobby, convincing them that bonsai are difficult to keep, as such they should be avoided. All of us have access to tree seeds, in parks or woods, our own gardens or perhaps through specialist suppliers. These will be 'fresher' than other sources.

When you have your seeds divide them into two lots. If you live in a temperate part of the world the chances are that your seeds will need to be chilled to start them growing, this is called 'Stratification'. Put half of the seeds in a container (a plastic bag) and place them in the refrigerator (not the freezer) for a few weeks. Plant the remainder straight away. If you come from the Tropics plant the seeds soon after collection.

They should be planted in a sturdy pot, or tray, and left to their own devices. This may take a year or so but provided they are not disturbed by birds, mice, or you, they should if fertile germinate. Last but not least, you have to put special importance on the surrounding environment before you start.

How to Store Seeds

Keep seeds out of direct sunlight in a cool spot that maintains a fairly consistent temperature. Consider a cold closet, a basement, or a room on the north side of your home that remains cool year-round. Freezing isn’t necessary for short-term storage, but you can refrigerate seeds, provided they are sufficiently dry.

All seeds need to germinate is sufficient water and temperatures that are favorable for plant growth. Make sure your seeds don’t sprout by storing them in a spot that isn’t humid and ensure the seeds are dry before sealing them in a container. Moisture is an especially important factor if you are freezing or refrigerating your seeds. If seeds are too wet, they can rot in the refrigerator or suffer frost damage in the freezer. If you store seeds in the refrigerator or freezer, place the packets in an air-tight container and ensure the seeds are properly dried to begin with. If you are storing seed you’ve saved yourself (bravo!), follow the correct seed-saving processes to ensure they are dry.

Consistency is key when it comes to temperature and humidity levels. This is why you should avoid storing seeds in a spot that isn't climate-controlled, like a garage or shed, where temperatures and moisture levels can fluctuate wildly.

We’ve all had a plant or two that’s caught the attention of a pest. Critters, rodents, and bugs also enjoy nibbling on seeds that are waiting to be planted. Choose a storage spot that is pest-free and you can keep a close eye on to ensure it remains that way. Glass jars, metal containers, or wire mesh can further protect seeds from invaders.

However, there is something to be said for a little breathing room. When using a storage area that is cool and dry year-round, you may be able to keep seeds in paper bags, mesh bags, or envelopes in what is called “open storage”. Moisture and heat generated by the seed during respiration can escape through these gas-permeable containers. This is also a smart tactic when you aren’t sure about the moisture content of the seed. But you will still want to take precautions to protect your seeds from pests.

Some seeds do not fare as well in storage. Crops like carrots, parsnip, onions, and leeks are notoriously short-lived. For these, freezer storage is best as seeds from these varieties that are stored at or near room temperature will quickly lose their ability to germinate and grow.

With these safeguards in place, you’ll be able to plant your seeds later and enjoy watching them grow.
