How To Keep Lobelia Blooming All Summer

In general, you can know how to keep lobelia blooming all summer using one maintenance practice, which is pruning. Much like anthuriums, simple maintenance practices and using a stable environment like the greenhouse can keep your plants blooming, encourage them, or even extend the bloom itself. However, you must check the many different lobelia species to determine the specific needs of your plants. 

More so, remember that lobelia plants are poisonous when ingested. If you’re pruning them, be mindful of nearby pets and children. Otherwise, this practice should encourage an extended blooming period while also preventing the plants from overgrowing

How To Keep Lobelia Blooming All Summer: Beginner’s Guide


Pruning lobelia

As mentioned earlier, there is only one practice to consider if you want to keep your lobelia plants blooming all summer. Pruning lobelia does not only improves the appearance of your plants and benefits their health. This practice will also encourage blooming and lengthen the duration of this period.

Many practices encompass the term pruning in lobelias. They include pinching, trimming, and cutting back. These methods differ on the ideal time to do so, and you’ll also do them with a specific outcome in mind. To extend the blooming period of lobelia in summer or encourage a second bloom, you can trim your plants at any time of the year. 

This encourages another flush of blooms, maintains their overall look, and some gardeners even prune the plant at half an inch when the blooming period ends. Depending on the lobelia plant you have, you can deadhead it to help the plant produce more flowers. Do note that some lobelias are self-cleaning anyway and won’t require you to remove the faded blossoms. 


Caring For Lobelia To Help With Blooming

While the straightforward answer on how to keep lobelia blooming all summer is by pruning the plants, the plant’s overall care will surely extend the flowering period. Remember that regardless of the plant you have, maintaining and caring for it is significantly influential to its blooms. For example, you can grow your plants in the greenhouse if your region experiences fluctuating climates.


Ideal environment

Remember that the ideal location of lobelias will vary depending on if they are annual or perennial. Annual lobelias thrive best in zones 1 to 10, while perennial lobelias can grow in zones 2 to 10. Some lobelias are also considered half-hardy annuals and perennials where some like full sun or partial shade. 

In general, the ideal temperature for lobelias is around 70°F. You can tailor the environment for your plants using a greenhouse to help promote flowering. More so, don’t forget that maintenance practices will also affect the health and blooming of lobelias. 


Watering and fertilizing

For example, during the summer, the dry and hot conditions will require you to water your lobelias more often. Always check their medium, especially those in containers, because they can get dry quickly. Annual lobelias will also require feeding to ensure that they will bloom throughout the season. 

Gardeners recommend a 12-4-8 liquid fertilizer every two to three weeks throughout the season. This will help your plants have enough energy to produce blooms without problems. Some even feed every four weeks or once a month with a general-purpose fertilizer as part of maintenance. 


Problems to look out for

Undoubtedly, preparing for common problems and doing prevention practices will ensure that they will bloom throughout the season without drawbacks. One of the most common issues that can halt lobelias to flower in the summer is when they experience drought. To anticipate this, water them deeply and mulch to conserve soil moisture. 

You also want to check the plants regularly for pests like spider mites, especially in the summer’s humidity. A useful technique to prevent mite infestation is misting with cold water with Neem oil. And if you noticed signs of infestation, isolate the infected plants immediately. 


Planting Lobelias

Knowing when to plant lobelia plants will also ensure that they’ll bloom on time in summer. You can grow bedding lobelias after frost at the end of May or early in June in the greenhouse. Once they have established themselves, you can transplant in early summer. 

On the other hand, you can plant perennial lobelias in early spring or autumn as long as the ground is not frozen. You can plant them at any time of the year as well, especially those with a greenhouse. 



Spring is not the only season to have a colorful garden. Knowing how to keep lobelia blooming all summer will land you a lively garden even when other plants have stopped blooming. The primary practice to extend the blooming period of lobelias is by pruning. 

Some plants also benefit from deadheading to help encourage them to produce more blooms. More so, maintenance and care for lobelias will guarantee flowering throughout the summer season. For example, use a greenhouse to maintain the ideal location for lobelias. 

Keeping the plants hydrated and well-fed will also encourage flowering and blooming in the summer. Water the plants deeply and feed them with a liquid fertilizer every two weeks. More so, mist with cold water and Neem oil to prevent summer pests like spider mites.

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.
