How to Grow Forsythia and Care for It
With most plants, you’re used to seeing the leaves first and the flowers later on, right? This one’s different.
The flowers of forsythia plants appear before the leaves. So, you can get an unblocked view of these gorgeous flowers.
The plant can bloom as early as late January, if you live in a warm climate, but most often, it puts on a nice yellow (or white) show in March.
Fact: The flowers tend to turn slightly yellow, purple, or maroon, depending on the amount of sunlight the plant has received.
Unless killed by the cold, these flowers can last for about two to three weeks. Careful with the pruning though, as that may easily ruin them! We’ll discuss pruning in a bit.
Growing Forsythia from Seeds
A fairly easy way to grow this plant is from seeds. If you don’t have it in a pot ready for transplanting, you can just get the seeds. It’s what many gardeners do.
Look for good quality seeds and a variety that’s adapted to your region. You can find seeds locally as well as online.

When to Plant Forsythia
You can plant the seeds anytime there is no freeze or frost. But it’s best to avoid planting them in hot summers.
Tip: The best time to plant your forsythia is early spring.
If you miss on planting it in spring, you can also plant it in the fall. But bear in mind that a harsh winter may damage it.
Forsythia is very tolerant of almost all soil conditions. However, it grows best in clay and loam soils. Not sure about your soil? Read more about soil types.
The perfect conditions for it to bloom are a well-drained garden and a medium nutrient content in the soil. The ideal pH level for these yellow flowering shrubs is 6.8 to 7.7.
If the pH of the soil is higher, you can use sublimed sulfur to lower it. If the pH needs to be raised because it’s lower than the recommended value, you can use powdered limestone.
Forsythia flowers grow best in full sun and while they can also do okay in partial shade, they may not bloom as beautifully. Less sunlight than that may lead to straggly growth.
So, make sure to always place your forsythia plant in an area that gets at least six hours of direct sunlight. Anything less than that, and you’re taking chances.
The perfect temperature to grow forsythia is between 55 to 70 degrees. The plants will be quite hardy in colder temperatures.
Keep in mind that forsythia grows well in humid climates. If the climate is too moist, the flowers will wilt, and in very dry conditions, they may not grow at all.
Often, you can water the plant only during long dry periods. But just to be sure, check the surface of the soil. Dry soil means your plant needs water–doesn’t take a genius to figure that out!
Also, pay attention to the leaves. If they sag down, it’s a sign that the plant doesn’t have enough water.
The best time to water your plant is in the early morning or evening. In the fall, winter, and spring, the plant normally doesn’t require additional watering (unless it’s an unusually dry season).
Tip: Because of the shallow roots, you have to pour the water slowly. This allows the plant to suck up the water from the upper soil before it can drain into the deeper layers.
Pruning plays an essential role in the healthy and beautiful growth of this shrub. If you don’t prune the bushes regularly, they can grow up irregular and frankly, quite wild-looking.
And that’s probably not what you’re aiming for, right? For a neat, compact look, you want to trim your forsythia from time to time.
If your flower is not blooming, it could be because of bad pruning. Since this plant produces buds on the previous year’s growth, it’s important to prune it right after blooming.
Tip: Before pruning, start by trimming 1/4 to 1/3 of the oldest branches. These must be cut right down to the ground. Along with encouraging new growth, this approach will make the shrub take a compact form.
You can also cut newer branches to give the shrub a nice and cleaner shape.
But keep in mind that you don’t have to prune this shrub every year. Some gardeners like the messy look of the shrub, which can look good in a rock garden, for example.
If you like the messy look, prune every two years or so. The bottom line is that pruning is good but not mandatory.
While this shrub loves the sun, it usually doesn’t have much of a problem surviving winter. Older shrubs, as well as those planted in the spring, can endure low temperatures without any problem.
The only exception is if you plant it in the fall. If you do that and you then get a harsh winter, your plant may struggle to grow and, in some cases, die.
Tip: If you live in a cold climate, best wait for spring to plant forsythia to make sure it will survive winter without any problems.
There are also two things you can do to protect your plant in winter:
- Add to it a good layer of brushwood or mulch.
- For potted plants: place them on a styrofoam plate and protect the container with a fleece or foil.
