How to Trim Verbena: The Basics

Verbena plants are a wonderful addition to any garden, which is why it’s no wonder why many gardeners want to know how to trim verbena. These plants don’t need much pruning compared to other herbs and perennials, but they need to be trimmed every now and then. This promotes new bloom and keeps your verbena looking nice and neat.

Pruning usually happens when spring starts to roll in. During summer, you can further trim your verbena so that more flowers will bloom. Remove dead flowers and seed heads during the fall season. Keep in mind that excessive pruning can slow down the growth of your verbenas.

Before we dive into the basics of how to trim verbena, it’s important to know what it is and what it needs to survive.


How to Trim Verbena: The Basics

Growing Verbena Plants

Most people are familiar with the shorter verbena variants that come in the shades of purple, red, blue, and pink. Verbenas look beautiful when placed next to other annuals. If you place them in your garden, butterflies, bees, hummingbirds, and other pollinators will become regular visitors.

Verbena is mainly used as a spiller plant in pots, but they can definitely liven up any space – indoors or outdoors. One of the best ways to beautify your greenhouse or garden is to plant verbena with dusty miller and red-orange marigolds. Even though these colors are perfect for the summer season, they will still be beautiful come fall.


Taking Care of Your Verbena Plants

Verbena plants are easy to grow; they need well-drained soil (soil quality doesn’t matter), six hours under the sun, and an inch of watering every week. These requirements are common for annuals, but unlike other hardy plants, verbena doesn’t fare well if you’re not consistent with your care. If your verbena goes weeks without regular attention, your plants may grow without flowers and the foliage would look unattractive.

Growing verbena directly in the ground will require less care and attention since the roots can grow well into the ground and solve their issues. On the other hand, container-grown verbena needs more frequent care since they’re placed in an isolated environment.


2 Ways to Trim Verbena Plants

There are two ways to trim your verbena plants depending on whether they’re annuals or perennials.


Annual Verbena

For annual verbenas, you can trim them regularly throughout the growing season to promote new growth and flowers. If you’re unsure when to trim your plants, do so when the verbena is thinning, straggling, or they’ve stopped flowering altogether.

Use sharp scissors or gardening shears and trim them about ¼ of their branches and stems. Apply flower fertilizer after trimming and be sure to follow the directions on the product label.


Perennial Verbena

Perennial verbenas thrive in cooler climates where temperatures go below freezing temperatures. Once winter has passed, prune your verbena plants using sharp scissors or gardening shears and remove wilted or dead plants. As with annuals, apply flower fertilizer following the directions placed on the label.

After the blooming of the spring flowers, you can trim your verbenas two to three times every summer. Cut them back about ¼ of their entire length to encourage new growth and flowers. You can also apply flower fertilizer if your plants look droopy and weak.

Keep in mind that perennial verbena will only need a light trim during the fall season. However, this can delay dormancy and lessen your plant’s hardiness. The best time to prune perennial verbenas is 45 days before the first frost date in your area.


Reasons Why You Should Consider Growing Your Plants in a Hobby Greenhouse

There are several reasons why it helps to grow your plants inside a hobby greenhouse. Here are some of the benefits of greenhouse gardening:


Protect from harmful insects

Gall midges, leafminers, aphids, mites, caterpillars, scale, mealy bugs, and whiteflies are one of the most common insects that can affect verbenas. If you already notice an infestation, use insecticidal soap and apply it to the affected area. Keeping them inside a greenhouse reduces the chances of attracting harmful pests that can damage your plants.


More space for planting

If you don’t have enough space to plant verbenas or other plants, you can use a mini greenhouse instead. You can place small greenhouses on your balcony, deck, patio, or even on tabletops. Even though they’re small, they function just like a regular greenhouse does.


Create a microclimate

You can plant crops and flowers inside a mini greenhouse regardless of the weather outside. You can use grow lights, heating and cooling systems, or natural heaters/coolers to create an ideal growing environment inside your greenhouse.


Protect from bad weather

Heavy rain, high winds, drought, and unpredictable weather can damage your garden in an instant. Keeping them inside a greenhouse keeps them safe from erratic weather changes. Once the weather warms and the spring season begins, you can transplant them into your garden if you want to.


The Bottom Line on How to Trim Verbena

Now that you know how to trim verbena, it’s important to remember and follow the tips mentioned above. Knowing how to grow and take care of verbena plants allows you to enjoy beautiful blooms for years to come.

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.
