GROWING HYDRANGEAS FROM SEEDS

Hydrangea seeds will not germinate

There are several reasons why hydrangea seeds do not germinate. Here we want to help you understand this issue because growing quality hydrangeas is the mission of our company.

It is also worth mentioning that like any business we are always looking for new ways to develop. One of these ways is growing and breeding hydrangeas. We hope that in the near future we will be able to offer you new interesting varieties and their seeds.

Choose right varieties of hydrangea (Quick Fire Hydrangea and Pinky Winky Hydrangea)

Yes, it is. The reason the seeds don’t germinate may be due to the characteristics of one variety or another. There are many different hydrangeaess on the market and they all have different germination times.

For example, there is hydrangea that germinates within 10 days of sowing. But it may also germinate a little later than is commonly thought (15 days).

The second type is a hydrangea of medium duration of germination. If you sow this type of hydrangea, you should expect the first green in 20 days, and sometimes longer.

Well at the end there are seeds that lie in the ground for a very long time and that they have to germinate must pass about a month. This is not a problem, just the peculiarities of the variety.

But if sprouts do not appear in a month, the reason is not in the hydrangea and you should consider other situations when this may happen.

The weather must be warm but not hot

Weather is the next important factor in hydrangea growth. If you sow in the spring, the hydrangea will not necessarily grow. At this time it is often quite cold and the seeds will lie in wait for the right air temperature.

A suitable temperature would be at least 55 F. In addition, this temperature should last at least a week. If there is a slight cold snap during this time, germination will be delayed.

The same applies to very high temperatures. In the summer heat, the seeds will not feel comfortable and will lie dormant until better conditions arrive. The same can be said about hydrangea seeds.

From all this, we can conclude that the best time to sow is April to May. It can also be done at other times of the year, for example in August, but you need to have the experience to do it right.

Irrigation should be done properly

Water is the most important condition for the germination of any seed. When seeds fall to the ground they begin to absorb water and swell, and only then a young sprout appears.

If there is not enough water, the seeds will wait for the rains to come.

To speed up germination, you need to keep the surface constantly moist. But don’t flood the garden. Too much water will cause the seeds to rot.

Also, don’t water too hard, you can just blow the seeds away. The same goes for rain. Heavy rain can push the seeds a long way from where you planted them. In this case, there is nothing you can do and you will have to sow again.

Seeds need sun

Many gardeners often sow hydrangea seed under large trees such as maples or magnolias. But this can be a problem because hydrangea needs light to germinate and dense tree canopies filter light.

You have to give the hydrangea at least 4 hours of sunlight to germinate. It doesn’t have to be the direct sun, diffused light is fine too. But hydrangea will not grow in full shade.

An excess of light works just as well as a lack of light. If you sow hydrangea in a sunny spot it might take quite a while to germinate, since the sun will dry out the surface quickly and the seeds will lack water.

Also, strong direct sun can burn the young hydrangea seedlings. So do not sow hydrangea in the middle of summer when the sun is shining with maximum intensity.

Soil also matters

And the last condition is the ground. In heavy clay soil the seeds will take longer to germinate because it will be more difficult for them to penetrate deep and create a root system. There is nothing you can do about this, you just have to remember that it will take longer than usual to germinate in such soil.

The opposite is true for sandy soils. It is easy for hydrangea to put roots through the sand. But this kind of soil has a disadvantage, namely water almost does not hold in it. As a result, the seeds will suffer from lack of water. To improve the situation, you need to water the hydrangea regularly.

Another factor is the acidity of the soil. In highly acidic or highly alkaline soil, the hydrangea will not grow. So before sowing, check the pH of your soil and if it is higher than pH 8 or lower than pH 5, you need to improve it.
