This process is known as stratification and will replicate the seed’s dormant period if you can’t plant the seeds outside in the late fall. You can use peat as an alternative to sand.
Sand, sandy loam soil, and a seedbed can be purchased online or at a gardening store. Keeping the seedbed inside will protect your seeds from potential disease and predators. You can also use a plastic cup or container to grow your seeds if you can’t buy a seedbed.
Even if your seed germinates, it may not grow to be a healthy evergreen.
If you’re keeping the seedbed outside and it’s raining on a weekly basis, you won’t have to water your seeds.
If it is under 60 °F (16 °C) outside, bring your seedbed inside so that the seeds can properly germinate. If you’re keeping your seedbed inside, make sure to keep it near the window where it gets plenty of sunlight.
If the seedlings haven’t germinated after a month, there’s a good chance that they won’t germinate.
Continue to water the seedling once a week before transplanting it.
Do not wait more than 3-5 days to plant the seedling.
Cut the roots on a straight line.
If you are planting the tree in a pot, make sure to get a pot that is at least 9–20 inch (23–51 cm) in diameter. If you’re planting more than one tree outside, make sure to space them at least 10–12 feet (3. 0–3. 7 m) apart from each other. [9] X Research source Evergreen seedlings should be planted where they will get plenty of sunlight, though some species like the Japanese yew and hemlock will grow in the shade.
The roots should not curl up or bend in the hole. If you need to, hold the tree in place to prevent this.
Giving the young evergreen trees enough water will encourage initial growth.
Remove and replace the mulch once every year for the best results. The mulch should be at least 1–2 inches (2. 5–5. 1 cm) away from the trunk of the tree.
Take a soil sample to see which nutrients you need for your lawn. After you add the fertilizer, make sure to water the tree thoroughly. The first number on the fertilizer stands for nitrogen, the second number stands for phosphorus and the third number stands for potassium.
The best time to prune evergreen trees is in the late fall. Prune new growth at a 40-degree angle. You may want to put wood glue over the areas you pruned to prevent the spread of disease. Before and after you prune the tree, disinfect your cutting implements with isopropyl alcohol. Wear gardening gloves when you prune. They’ll protect your hands and improve your grip on the cutting implements.
You may have to replace evergreen trees that have been too badly damaged by diseases or rot.
If the infestation persists, you may want to catch one of the pests and take it to a cooperative extension so that they can tell you which insecticide works best. Wear gloves and facemask when handling insecticide.
