A gardener who achieved large, and healthy-looking hydrangea blooms took to online forum Reddit to show how the flowers look and also revealed how they achieved such lovely blossoms.

They shared a couple of rules they followed to get the big blooms when a fellow Redditor inquired about how many years it took to get their flowers to be that size.

The steps they followed have “worked out well” for them and helped them achieve four hydrangea shrubs, all about five years old, having reached approximately eight feet tall and about six to eight feet wide with easily “60 to 80 flowers” on each shrub by the fifth year.

“They’re magnificent,” the Reddit user said of the blooms, admiring their hard work.

The hydrangea lover said it took them about five years to reach the results mentioned earlier. First, they advised readers to prune hydrangeas properly not “like a dictator.”

The hydrangea fanatic said to clean the rootball at the start of spring, put down lobster compost or similar, and then cover with mulch.

They dove into an explanation about cleaning the rootball, saying that as time passes, dead leaves and other things get stuck to the rootball – which they described as “the part of the plant where all the branches go into the ground.”

They said to properly clean that area so that it’s free and clear of any debris. They added to apply compost on top of it, about an inch or so, from the center of the roots all the way out to “under the canopy” of the plant.

They added: “Most importantly, you have to stake them when they get this big. Unfortunately, when they flower, rain really makes the flowers super heavy and they start drooping and look awful even though they have a month or more of life left in them.

“I tie around the plant several times with twine and that seems to work although there are better options for people who aren't as lazy as I am.”

People were enamored with the Reddit user's results. One person wrote: “This is absolutely stunning!!! I am so jealous!”

Another said: “Gorgeous! Mine aren't that big yet, but I also just planted them and let ‘em go.”

It’s not clear the exact type of hydrangeas grown by the Redditor, but many people suspected they were Limelight hydrangeas.
