How To Grow Chinese Elm From Seeds - Method One

When planting Chinese Elm from seeds, you’ll need patience, along with good fertile soil, ziplock bag, and Bonsai pots.  You can also use paper cups to substitute for the bonsai pot. 

Step One

First, you need to soak your seeds in lukewarm water for 24 hours. Soaking your seeds will get them to swell enough that they’ll be ready for sowing. It’s important that you don’t leave them soaked for too long as this will result in the seeds rotting or turning sour. We recommend that you soak them for a period of 12 to no more than 24 hours. 

Step Two

After soaking your seeds, place them in a ziplock bag. Put potting Bonsai soil and the seeds and make sure that the paper bag is sealed properly. The soil should be damp, so you may have to add water to it as time goes by. Make sure that it is just moist, not wet. Keep the ziplock bag in the refrigerator for 2-3 months. Check on it gradually, and ensure the soil has not dried out. 

Step Three

The third step is preparing for planting. Place 3-4 seeds in each paper cup or bonsai pot. We suggest a high-quality soil mixture to nurture your trees. Chinese elm seeds are sensitive to dry soil. Water your soil properly before planting. 

Step Four

You will then have to cover the pots with plastic and place it in a warm, dry place. The correct approximate temperature is around 75 to 85 degrees F.  After the first set of true leaves appears, and you can cut off any unwanted seedlings.

How To Grow Chinese Elm From Seeds? - Method Two

There are many ways to kill a cat and different methods to plant Chinese Elm trees. This method works best if you are growing your trees in a greenhouse.

Step One

The first step requires you to plant the seeds while still green. Wait for them to be fully grown but not dried out. The seed pods are usually fully grown from the Chinese Elm tree during the fall season. Open the pods to extract the seeds and ready them for planting.

Step Two

You will need potting soil and a potting tray with drainage holes for this step. Ensure that the soil you use is either sandy or loamy to avoid water getting retained. Cover the tray with soil evenly. After that, place the seeds on top of the first layer of the soil. Leave about two to three inches of space in between the seeds. When you have put all the seeds, cover up with another layer of soil, with about a quarter of an inch in depth.

Step Three

Water the soil thoroughly and let the water be drained out of the holes of the potting tray. Continue watering until the soil is saturated. Place the tray in a greenhouse or a warm area that receives direct sunlight. Keep watering whenever the soil begins to dry out.

Step Four

In a couple of days, the seeds will start to germinate. When the following growing season approaches, you will notice that the seedlings have grown to at least six inches. You must re-pot them at this stage, dividing them and placing them into different containers. Keep them placed in the greenhouse throughout the following winter.
