When To Cut Back Endless Summer Hydrangeas

Knowing when to cut back endless summer hydrangeas in early fall will help rejuvenate them. Like other perennials, endless summer hydrangeas will thrive well in the greenhouse but still requires consistent management practices. This includes proper cutting back or pruning as these flowers benefit well with this practice.

Endless summer hydrangeas are perennials that are best for zones 4 to 9. Since you’re growing them in the greenhouse, you can prevent potential problems with outdoor conditions. They bloom longer than other hydrangeas, and you can benefit from this with proper care alongside maintaining the ideal environment indoors.

When To Cut Back Endless Summer Hydrangeas

When To Cut Back Endless Summer Hydrangeas Correctly

Generally, you can cut back endless summer hydrangeas when a flowering stem fades. One of the unique and well-loved characteristics of endless summer hydrangeas is that they bloom 10 to 12 weeks longer than other hydrangeas. When you cut a faded flowering stem back, it will encourage new growth and flowering buds.

They can rebloom throughout spring and summer and use both new and old growths. This means that the woody stems and the new stems are both useful for blooming, and your greenhouse will be colorful from spring through fall. However, know the proper ways to cut back in spring or fall.



Early in spring, you’ll notice that the perennials will be full of dead stems. However, don’t make the mistake of cutting the plants because these woody stems will still bloom. You want to avoid cutting back buds that can bloom and, instead, let the new growth emerge and overcome the dead-looking branches.

Spring is not the best time to cut back. Instead, you wait for longer in early summer to trim the dead tips. This will keep the hydrangeas blooming and thriving as they should be.



The best time to cut back endless summer hydrangeas is early in the fall. Why at this time of the year? When you cut back the plants after it finishes blooming, you can control their size and shape. 

Compared to mistakenly cutting in early spring, you won’t also risk preventing buds from blooming. In fall, you have the option to cut off the dried flowerheads. However, note that if you cut the perennials to the ground, it will take until spring for the buds to mature. 

It’s also typical for some gardeners to leave the dried flower heads in winter instead.


How to prune endless summer hydrangeas

Pruning your endless summer hydrangeas in the greenhouse makes it possible to take full advantage of its capacity to bloom longer and rejuvenate for better health. For example, you can prune the plants in summer by cutting the oldest stems down to the base. This way, you’ll help the hydrangeas get better branching and encourage fullness.

However, there’s a catch on this practice. Check your hardiness zone, and if your state is in zone 4 or 5, you don’t have to prune unless necessary. As mentioned earlier, you can prune immediately after blooming. 

Pruning in spring is not a common practice. Instead, you maintain your plants by removing the dead stems. If you need to revive your damaged or old hydrangeas, prune all the branches down to the base. 

The plants won’t flower in the upcoming season, but this will encourage healthier blooms for years later on. Some gardeners also recommend pruning in May to help the buds that survived winter to emerge. You can also deadhead the spent flowers to encourage the setting of buds for blooming throughout the season.


How To Overwinter Endless Summer Hydrangeas

If you live in the northern part of the country, you should also learn how to properly overwinter endless summer hydrangeas. We all know how the greenhouse is useful for overwintering most crops, but knowing the proper practices unique to these perennials will ensure overwintering success. However, do note that the information below is best if you’re overwintering in the first year.

You must stop applying fertilizers after August 15 to help the plants prepare for winter. For the watering, keeping the soil moist is optimal in the fall until the ground freezes. When the plants get dormant around the end of November, cover the plants with mulch and then uncover in spring.

Do not immediately get discouraged if the plant takes time to grow from the base or old branches. The heat in late spring shall help the plants grow. Once this happens, prune back the old branches.



One of the reasons why endless summer hydrangeas are well-loved is that they bloom for a long time and grow both on old and new stems. The greenhouse already helps in maximizing this characteristic, but you must learn when to cut back endless summer hydrangeas. In general, you cut the plants back when a flowering stem fades.

However, you can best control the perennials’ size and shape when you cut them back after they finish blooming. This is typically in early fall. Additionally, take the time to prune and overwinter your hydrangeas to keep them thriving properly and your greenhouse colorful. 

Endless summer hydrangeas are also typically forgiving if you prune at the wrong time, and recently planted perennials will even thrive best if you leave then alone.

How To Prevent Root Rot In Hydroponics: 3 Useful Tips

If you’re a newbie gardener who’s looking to find ways to hone your skills, you’d want to learn how to prevent root rot in hydroponics even before this problem affects your plants.

Hydroponics can be advantageous to crops in more ways than one. However, it also comes with risks of diseases, such as root rot, which can be destructive or even lethal to your plants.

Unfortunately, there are no effective methods to recover the wilted parts that were affected by the root rot once it hits your plants. The only thing you can do if you do not want this catastrophe to befall your crops is to prevent it before it happens. Read on to learn more about this subject.


What is Root Rot?

Root rot is a disease that attacks the plant roots and causes them to suffer decay. This usually happens when a lack of oxygen supply occurs in the substrate.

To give you an idea, think about plant roots that are submerged in water that only has a little oxygen in it. Over time, the plant suffocates and dies.

Aside from rot and decay, this disease also leads to the proliferation of fungi that are naturally present in the soil. These include Rhizoctonia, Alternaria, Pythium, Botrytis, Fusarium, or Phytophthora. As soon as fungi colonies start to grow, they tend to target the weakened roots and infect your precious plant babies.

Once the plant becomes infected, they won’t be able to take in what they need to grow – water, oxygen, and other nutrients. When this happens, it won’t be long before the plant dies.


What is Hydroponics?

In case you’re not aware, the term hydroponic is derived from a Latin word that means “working water”. To put it simply, hydroponics is an art that involves growing various types of plants without soil. If you’re like most people, the first thing that comes to mind when somebody talks about hydroponics would be a picture of plants with roots suspended into the water without using any type of growing medium.


Avoiding Root Rot in Hydroponic Systems

Detecting and identifying root rot can be tricky. When your plants get infected, their leaves and roots gradually wither until the whole crop itself dies from the lack of nutrients, which is a common symptom of many diseases.


What causes root rot in hydroponics?

One of the requirements in hydroponics systems is oxygen. Without it, your plants are basically on the road to death. On the other hand, lack of such is one of the major triggers for root rot, and it must be avoided at all costs.

Just like when planting in soil, you loosen up the ground so that your plants’ roots can have their required intake of oxygen. That is the case for crops grown in aqueous solutions as well. If they cannot breathe, they would not be able to grow.

Another agent for root rot is the temperature. The last thing you would want in your system are parasites that leech nutrients intended for your plants and infect the water during the process. In common terms, these fungi are called molds.

One of the best breeding grounds for these is warm and moist areas. For this reason, if the water temperature inside your reservoir is high, then you are susceptible to it. Something as minor as letting the solutions exposed to sunlight can already be a risk factor.


3 Useful Tips on How to prevent root rot in hydroponics

There is good news! Root rot in hydroponics can be prevented! Just follow these tips:

Tip#1: Use the right air pump

If you do not want root rot to affect your plants, you merely have to avoid its causes. If you need oxygen, keep the water bubbling by providing an air pump of appropriate size, and also give importance to proper ventilation in the room.


Tip #2: Maintain the temperature

The temperature should be maintained within the 70 to 80 degrees F range. Get rid of any materials that can make your system vulnerable to infections, and make sure not to disturb your crops while they are trying to grow.


Tip #3: Get rid of the rotten parts

However, if you failed in preventing the disease, then the rotten parts should be removed immediately. Cut them off as there is no chance of reviving them, and focus on the potential new growth instead. Fix your hydroponics system and eliminate the risks.


Why Give Greenhouse Gardening a Try?

Greenhouse gardening offers numerous benefits to greens aficionados who dare to take their gardening experience to the next level. Aside from acting as a shield against the effects of inclement weather, a mini, hobby, or semi-pro greenhouse can also serve as a protective layer that keeps harmful bugs and critters at bay.

What’s more, its enclosed structure allows you to control your plants’ growing conditions including the temperature, light, moisture, and ventilation of the greenhouse’s internal environment. With a controlled environment, you’ll be able to extend growing seasons and grow plants that aren’t native to your area.



No matter how well-informed you are about how to prevent root rot in hydroponics, you cannot completely eradicate the risks. Therefore, to avoid the worst-case scenario, you should be prepared to sacrifice the infected for the sake of others. While you’re at it, consider trying your hand at greenhouse gardening as well.
