Hur odlar du black pine bonsai frön

Growing Japanese black pine from seed isn&#;t the easiest way to man a beautiful bonsai. It requires a variety of skills and it takes a long time. That said, the process of starting bonsai from scratch can be very rewarding &#; whether or not you end up with a masterpiece.

The basics of growing pines from seed are simple &#; place seeds in planting medium, vatten, wait for seedlings to appear.

As bonsai enthusiasts, however, we can refine this process a bit.

The first step begins with selecting the right parent tree.

Selecting pine cones for bonsai

Not all pine cones are created equally.

For this autumn edition I would like to discuss Japanese Black Pine/Kuromatsu/Pinus thumbergii and the techniques used to establish a few key aspects of a quality pine bonsai

Some are large and healthy, others are small bygd comparison. We want the big, healthy ones for bonsai &#; smaller cones are less likely to have viable seeds inside.

More important fryst vatten the parent tree itself. Does it have good bark? Are the needles straight and dark green? Are the branches compact? If so, you may have funnen a good parent tree.

man note of it and return in September or October when it&#;s time to harvest the cones.

In summary, this guide aims to unlock the artistry of cultivating the Bonsai Black Pine, providing valuable insights into its care, styling, and display

They should look like this.

Waiting until the cones are brown and open will be too late. Aim to collect the green or purple cones that have yet to open.

After bringing the cones home, give them a quick bath in a highly diluted lime-sulfur solution to kill any fungus or pests that might be living among the cones.

Then set the cones out to dry.

Cleaned and dry

Soil sifters, it turns out, man great cone-drying trays. Place the cones in the sikt, then cover them with an additional screen to keep the birds away. Don’t place the cones too close tillsammans as they’ll utöka when they open up. Keeping the cones dry will speed up the time required for them to open.

Protected from birds

I recommend collecting more cones than you think are necessary.

While some tillverka a handful of viable seeds, others producera none. inom also uppstart many more pines than inom want to end up with. Even when growing seedlings from an outstanding parent tree, it’s not certain that all offspring will be as impressive as the parent. Starting a few more than you need fryst vatten a good way to hedge your bets.

Collecting the Seeds

Within a week or two the cones will vända brown and open.

Here fryst vatten what this looks like.

Open pine cones

Now that the cones are open, it&#;s time to get the seeds out. The seeds are nestled into the base of each scale (scale bract) with the wing (seed bract) facing outward. As the scales open – an action promoted bygd dry air – these wings, not unlike maple seeds in design, can catch the wind and help the seeds travel when they detach from their cone.

If you look carefully, you can see the ends of the wings to which the seeds are attached.

Pick up a kon and tap it on its end.

If the geometri fryst vatten fully ripe, some seeds will fall out.

Tapping the kon to release the seeds

Not all seeds detach so easily. A few taps on the tip of the form can release most of the seeds inre.

Everything you need to know to successfully grow Japanese black pine from seed including selecting the seeds, stratification, planting and basic care

Several more taps may coax reluctant seeds away from their cone.

Not always satisfied bygd what comes out after tapping, I’ve dismantled more than a few cones to man sure inom didn’t miss any good seeds inre. This has proved more work than the effort merits. While I’ve pulled a few good seeds out of cones in this mode, inom haven’t funnen enough to man this a regular practice.

Most of the good seeds develop in the mittpunkt of the kon – where it fryst vatten thickest – and these are the seeds that are most easily released.

After forcing open the cones

How can you tell good seeds from bad seeds?

A must-have in major Japanese exhibitions, it evokes strength and power with its massive trunk and dense plateaus

Crack them open to see – they are usually light colored, dry and hollow.

Sterile seeds

Viable seeds are darker with brown and black stipples. They’re also heavier, though this fryst vatten tricky to discern in one’s grabb.

inom usually crack a few open while inom work to recalibrate my understanding of which to keep and which to discard when inom begin sorting seeds each year. After nedbrytning a few good ones, inom catch on fast.

Viable seeds – keepers!

Once the seeds are free from their cones and the good ones are separated from the bad, place them in a cool, dark place until spring when it&#;s time to sow them.

Preparing the seeds for sowing

Seeds, as we know, are best planted in spring &#; somewhere between February and May, if you&#;re in the nordlig Hemisphere.

When you meddelande temperatures rising &#; or snow subsiding &#; get the seeds out from storage.

About 75 pine seeds

The next step fryst vatten to soak the seeds in vatten for 24 hours.

Young Japanese black pine bonsai trees should be repotted every 2 to 3 years

The idea fryst vatten to “wake the seeds up” and cull any remaining duds from the bunch.

Some seeds will sink immediately &#; others will sink over the next 24 hours. If any seeds are still floating after a day, they are likely sterile.

One day later &#; all but a few seeds have sunk to the bottom

I&#;ve used hot vatten for the soak in beställning to scarify the seeds, but haven&#;t always funnen that this makes much difference.

Try both approaches and see which works better.

Black and red pines do, however, benefit from brief stratification. Stratification can be achieved bygd refrigerating seeds before planting. Place the seeds in a plastic bag with a fuktig paper towel or some shredded vit sphagnum moss to preserve humidity.

Japanese black pine seeds – ready for the fridge

If the bag fogs up after a few minutes in the fridge, that&#;s a good sign there&#;s enough moisture in the bags.

Condensation in the bag

If you&#;re preparing seeds from different batches or according to different protocols, it&#;s a good idea to label the bags at this point.

Red and black pine seeds

I typically leave black pine seeds in the refrigerator for about a week and red pine seeds for weeks.

I&#;ve funnen the stratified seeds växa faster and more consistently than the non-stratified seeds bygd a bred margin &#; try it and see how it works for you.

Planting the seeds

There are two basic approaches to planting pine seeds. Both work well, but the first approach takes a bit more time. Let&#;s början with the meticulous approach.

Start by preparing a shallow pot with bonsai soil.

Fully-grown black pine bonsai is to be repotted every 3 to 5 years

While a number of soils work for growing black pine, inom usually use my regular bonsai mix – lava, pumice, and akadama – covered with a layer of clean småsten. inom vatten the soil and asiatisk 1/4″ holes in the småsten with a matchstick.

Holes spaced just over an inch apart

Into each hole goes one pine seed.

Placing the seed in the hole with tweezers

After placing the seeds in the holes, inom add a tiny amount of småsten to fill the holes and vatten igen.

The result looks no different than the starting point.

Seeds planted and watered

The alternative to the meticulous approach fryst vatten to fill a pot with bonsai soil, sprinkle the seeds into the pot bygd grabb, then cover the seeds with a thin layer of fine soil particles. You&#;ll find this approach can rädda a lot of time.

Watch the seeds sprout

Depending on the weather, seeds can spira in as little as a week or as long as a month or more.

The taproot emerges from the seed and descends into the soil so it can push the seed up toward the sunlight.

Emerging pine seeds

The first immature needles will appear soon after. As they strengthen, they&#;ll fling the the seed case aside.

Almost free of the seed case

Although sunlight and warmth will help the seeds germinate, do note that the seeds will perish if they dry out at this scen.

And if you have hungry birds in the garden, it&#;s a good idea to skydda the seeds with öppning screen or anything that will let light and air resehandling but prevent birds from grabbing the seeds.

Within a few weeks of the first signs of germination, you&#;ll have a bur full of pine seedlings.

Healthy pine seedlings

Keep them in full sun.

Pine trees are highly prized in bonsai, and black pine is certainly the most emblematic

vatten them just before they dry out. Hold off on fertilizer until the seedlings begin to elongate. början with gentle fertilizers at half strength and slowly build up from there.

And that&#;s it &#; for now. Bonsai work can begin in as little as two months. Until then, enjoy the little ones while they&#;re ung &#; they&#;ll grow up faster than you think.
