Most Japanese maples grow at a slow to moderate rate of 1 to 2 feet per year. They typically grow fastest when they are young and slow down as they reach maturity. Planting them in a spot where they are happy and caring for them well helps maximize their growth rate.
Growing Japanese Maples from seed is a slow but highly rewarding process. In two to three weeks if the weather is warm, you should see seedlings start to pop up. The first set of leaves they produce are called cotyledons.
Poke a couple holes in the bag for ventilation, and put it in your refrigerator for 90 days to stratify. Once the 90 days are up, you can plant the seeds in a container or directly in the ground. If you live somewhere with cold winters, you can skip the fridge and simply sow your seeds outdoors after they soak.. . . . .364011233858!]0000000000000009783314146033!]
