You need to find out how to get rid of aphids in your greenhouse if you want to keep your gardening efforts from going to waste. In case you’re not aware, an aphid infestation can be devastating to your crops and plants.

While placing your plants in a mini greenhouse lowers the risk of attracting harmful insects, it doesn’t mean that it won’t happen. First, let’s find out how aphids harm your plants and what attracts them to your garden.

How to Get Rid of Aphids in Your Greenhouse

What Makes Aphids Harmful to Plants?

Aphids are phloem-feeding bugs that have a piercing-sucking mouth to suck the nectar and other metabolic products made by your plants. These pesky little bugs can only cause minor damage to the tissues, but it sucks your plant’s nutrients and energy. Additionally, aphids can carry certain diseases that can infect and even kill your plants. Lastly, when aphids feed, your plants will produce honeydew. This sticky substance is the perfect environment for mold to grow.


What Attracts Them to Your Garden?

Certain environmental conditions attract aphids to your garden, causing them to reproduce and cause further damage. Prevention is better than cure, so it’s best to prevent aphids before they could even get to your plants.

Keeping your plants healthy is the key to prevent diseases and infestations. Here are some of the tips you need to remember to avoid harmful insects from infecting your plants:


Tip #1. Avoid overcrowding

Your plants shouldn’t be overcrowding, so make sure they are appropriately spaced.


Tip#2. Use the right kind of soil.

Grow your plants in nutrient-rich and well-drained soil.


Tip #3. Ensure proper ventilation

If your plants are in a greenhouse, there should be enough ventilation.


Tip #4. Protect them from inclement weather

Extreme temperatures are also harmful to your plants, so make sure they’re safe from unpredictable weather.


Tip #5. Water your plants regularly

Create a sufficient watering or irrigation system specific to the plants you’re growing. It should give constant and appropriate moisture to your plants.


Tip #6. Keep everything clean and weed-free

Your garden soil should be regularly sanitized and make sure that you regularly remove the weeds from your garden.


Tips #7. Apply pest prevention techniques

Practice proper crop rotation and succession planting.


Tip #8. Grow plants that resist aphids.

Plant aphid-resistant plants around your crops to prevent them from transmitting diseases.


Tip #9. Don’t use nitrogen fertilizer

Add organic fertilizers when necessary but avoid using excessive nitrogen fertilizer because aphids are attracted to them.


How to Get Rid of Aphids in Your Greenhouse

Once you notice there are aphids inside your greenhouse, make sure to address the problem ASAP. These bugs can quickly reproduce and become resistant to different pesticides. It’s easier to prevent an infestation than control it, but if they’re already in your greenhouse, here’s what you can do:


Step 1.

Regularly check your plants at least once a week for any signs of aphids. Look for sticky discharge, mold, or curling leaves. Make sure to check the underside because that’s where aphids usually hide.


Step 2.

For initial problems, prune the stems covered in aphids and take them out of the greenhouse.


Step 3.

Spray your plants with a mild insecticide specific to targeting aphids. You can purchase this in your local garden store. Make sure to follow the instructions written on the directions.


Step 4.

Buy insects that prey on aphids and place them inside your greenhouse. Lacewings, ladybugs, and damsel bugs can control the number of aphids without harming your plants.


Step 5.

Plant companion plants that ward off aphids that lurk around your greenhouse. Some examples of great companion plants are the ones that emit a strong odor, including mint, dill, petunias, chives, garlic, and coriander.


The Benefits of Planting Inside a Mini Greenhouse

Greenhouses are a great place to grow plants because they create an ideal and enclosed environment for your plants to grow all year round. Other than that, greenhouses also protect your plants from insects and shielding them away from high winds, excessive rain, and unpredictable temperatures.

Other than that, here are some of the ways you can benefit from having a mini greenhouse:


Great for gardeners with limited space

If you’ve always enjoyed planting, but you don’t have enough space to grow different crops, you can use a mini greenhouse. Small greenhouses have a standard size of six feet, but there are smaller ones if this is still too big for you. You can place them anywhere – indoors or outdoors – and you can plant almost anything inside.


Start planting your crops earlier than usual

With a mini greenhouse, you can create an ideal climate for your plants so you can plant them at any time of the year. You’ll be able to grow crops and ornamental plants before the cold season starts in your area. Once the weather warms, you have the option to transplant your plants into your garden. By planting earlier than usual, you’ll be able to harvest crops earlier.


Protect your plants from snow and frost

A small greenhouse is excellent for tender plants that are sensitive to weather changes. Planting them inside a greenhouse can protect your plants from ice, frost, and snow during the colder seasons. You can place your plants inside until it’s safe for you to transplant them outside if you want to.


The Bottom Line

Now that you know how to get rid of aphids in your greenhouse make sure to act on the problem as soon as possible by following the steps outlined above. If you don’t have an infestation problem yet, it’s best to take the necessary actions to prevent them from damaging your plants.

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.
