By The Editors. When to Plant Forsythia Bushes The best time to plant forsythia is in the fall, while the plant is dormant. Choosing and Preparing a Planting Site Select a spot in full sun where the shrub will have plenty of room in which to grow and expand. Depending on the cultivar, the shrub may reach up to 10 feet in height and 12 feet in diameter, so plan accordingly—or plan to prune regularly.
Forsythia will adapt to most soils, though they prefer loose, well-draining soil. They do best in soils with a pH that ranges from about 7. How to Plant Forsythia Bushes Dig a hole at least 2 times wider than the root ball. Make sure that the top of the root ball is at ground level. Pack the soil firmly around the roots.
Water deeply at the time of planting. How to Care for Forsythia Bushes Other than a yearly pruning, forsythia do not require much maintenance. Apply a fertilizer high in phosphorus in early spring each year. Softwood forsythia cuttings taken in late spring to early summer will root readily, allowing for easy propogation. Remove older branches by cutting them off at the ground. Redbud trees and cherry trees make great companions because they give a strong color contrast.
Flowering quince, and daffodils are also good choices, sine they flower in early spring as well, giving a good show of early color. Dig a hole that is at least two times as wide as the root ball of your plant and the same depth as the root area. Remove the plant from the container and set the root ball into the hole. Make sure that it will sit at the same level with the ground. Fill in the space around the plant with more good quality soil and tamp it down firmly around the roots of the plant.
Water the plant well. Transplanted shrubs can suffer a bit when moved from a pot to the garden and watering the area well gives it a better chance of withstanding the move with ease.
After watering, the soil level many look lower near the crown on the plant. Just add a bit more soil It is best to hold off on adding commercial fertilizer until the plant has become established. If you order online, you will often get bare root plants which will be shipped according to your hardiness zone. These plants are available from many mail order nurseries. They are generally less expensive than potted plants, but are also smaller as well.
Forsythia is a fast grower, so a bare rooted plant may be perfect for you! Bare root plants are shipped in a bag with a planting medium — normally sphagnum moss or shredded cedar. This is placed around the root system to keep it moist. Dormant plants will not have leaves. But actively growing plants may have some leaves showing. Prepare the soil in your garden by adding some organic matter and be sure to plant very quickly once the specimen arrives.
The shipping medium should be added to the planting hole along with the bare root plant. Try to plant it at the same depth as the original plant was planted. Check the trunk of the plant. You should see a tree ring which shows that level. They will only last a short while in the shipping medium.
Water the plant regularly for the entire first year. You will get the best results if you choose a bare root plant from a nursery in your own hardiness zone.
Not only may it arrive more quickly, but it will have been grown according to local conditions. If you are hoping for that lovely yellow color all year long, you will be sorely disappointed.
Forsythia has the blast of spring color and then turns into a lush green plant until the cold weather hits. Once the plants have gone through a frost, they will lose all of the leaves and flowers and show only the long arching canes in the winter months. To enjoy the color during the winter months, try forcing the branches indoors even when there is snow on the ground. See my tips for forcing forsythia here. While buying plants from the garden centers is the quickest way to get a new plant, it is also the most expensive.
Forsythia branches root easily and will give you new plants to use in other parts of your garden, if you are patient to wait for them to take root. Layering and taking cuttings are the two of the easiest and fastest ways to root a forsythia shrub. The process is simple enough that even a beginner with not much of a green thumb can have success with this easy to root plant.
These branches will be more tender and will root more easily. To take a cutting, just remove the leaves from the bottom have and dip the bottom tip in a rooting powder. Place them in sand, a good seed starting soil or perlite, mix and keep moist. You should have rooted cuttings in weeks. Then you can move them to their own larger pots with normal potting soil until they are more established and are growing.
You can then plant them in your garden. For a forsythia, this is the easiest way to get a new plant. Keep the area around the base of the plant free from weeds and grass.
For the first two to three years after planting a new forsythia, let it fill out and don't prune it. This will help it establish a good root system. Even more flowering potential and they can easily be kept to the size of the container. There really is no preventative measure to stop this. You could try netting the forsythia until the flowers appear but it sounds like too much work for us. If plant and soil conditions are right, established plants can grow with very few maintenance measures.
The border forsythia is a robust flowering shrub, which is suitable for almost every garden. Concerning the demands on its location, the border forsythia is absolutely undemanding and adaptable. In a sunny location, the showy forsythia will thrive just as good as in a rather shady place. The shrub can therefore be planted almost anywhere in the garden, depending on nothing else than your decorational wishes. The best flowering is to be expected in a sunny and warm location.
As long as the soil is not extremely calcareous or prone to waterlogging, this flowering shrub is very tolerant to all soil conditions. The border forsythia grows easily on nutrient-rich but also on poor soil. Perfect growth conditions are provided by well drained garden floors with a medium nutrient content.
Basically, these pretty flowering shrubs can be planted all year round. Only frost periods and high summer periods are less recommended planting times. However, this spring flower will grow best when it is planted into the soil in early spring.
Despite the border forsythia being winterhardy under virtually any conditions, it does need a little time to grow properly. The best planting time for the shrub begins as soon as the soil is frost-free in spring. It is advisable to loosen the soil in advance with the rake or a spade and to free it from stones, weeds and old roots.
The planting of a Forsythia x intermedia into a pot is very similar to the open-air planting. The pot must be of sufficient size and contain drainage openings at the bottom. A saucer is better than a cachepot, because the excess water is easier to recognize and can be poured away. Generally, the replanting of large shrubs is rather difficult, because the root ball can be damaged. If a change of location is indispensable, a preparatory action is necessary in spring.
For this purpose the roots are parted off with a spade at a distance of about 40 cm around the plant. This way, new, fine roots are formed. Nevertheless, enough undamaged roots will remain so that the shrub does not die. In the following late autumn to early spring during the winter rest the border forsythia can then be lifted out in a radius of about 60 cm and be replanted to a different place in the garden.
