How to Pinch Dahlias: What You Need to Know

Why Pinch Dahlias?

Cutting your dahlia’s main bud will encourage more growth on the lower stem, leading to the development of new stems. Your plants will grow two shoots instead of one main stem. When you pinch dahlias, your plant will focus its energy on producing leaves and stems rather than buds. It may take an additional 7 to 14 days to see blooms, but gardeners would rather wait so they could reap stronger and fuller plants. Additionally, you’ll also experience longer-lasting blooms that you’ll enjoy well into October.

Cutting flowers during summer or early for your arrangements and bouquets is also as beneficial as pinching. It keeps your plants healthy and it encourages more buds to develop. Lastly, deadheading also helps your dahlias bloom beautifully.

 

When and How to Pinch Dahlias

Now that you know why you need to pinch dahlias, the next thing you need to know is when and how you should do it.

The best time to pinch your flowers is when they’re around 12 to 15 inches tall and they have at least four to five sets of leaves on the center stem. At this rate, your dahlias are growing quickly and they’ll easily recover from the pinching.

Here’s what you need to know about pinching dahlias:

When your plants are tall enough, pinch off the top part of the plant (above the leaves). This process is also referred to as “topping” your plants.

To properly pinch your dahlia plant, you can use gardening shears, scissors, or even your fingers. However, make sure to do it gently so you can’t tear the stem. You can continue to pinch your dahlias to encourage new growth and more flowers as they grow. If you want to grow larger flowers, you can pinch a few buds in areas where several are grouped.

 

The Benefits of Growing Dahlias in a Mini Greenhouse

Growing dahlias in a greenhouse ensure that your flowers will successfully bloom. There are several other benefits of growing plants in a mini greenhouse. Here are some of them:

 

Protection from pests and diseases

Dahlias are prone to attract thrips, mites, leafhoppers, and aphids. They can also catch several diseases such as stem rot, mosaic virus, aster yellows, viral issues, and botrytis. If you keep your plants inside a mini greenhouse, it reduces the risk of contracting diseases and attracting harmful pests that can damage or even kill your plants.

 

Great for gardeners without enough space to plant

If you want to plant flowers or crops but you don’t have enough space, you can use a greenhouse. A mini greenhouse is the most cost-effective version of the large greenhouses most people are familiar with. Its standard size of six feet makes it easier for homeowners to place their greenhouses in balconies, patios, and decks. If the standard size is still too large for you, there are smaller options that can fit tabletops.

 

Perfect for gardeners who want to learn about greenhouse gardening

Interested in learning about greenhouse gardening? A mini greenhouse is a perfect place to start. It’s cheaper than the regular-sized greenhouses, yet it provides the same benefits. You’ll be able to learn the ropes without having to shell out thousands of dollars. You can learn the ideal growing conditions of your favorite plants and how they grow inside a greenhouse.

 

Start growing your plants early

With a mini greenhouse, you can start growing your dahlias even before planting season begins. Greenhouses allow you to control the temperature inside using heating and cooling systems. Once the weather warms, you can transfer your flowers into your garden or outdoors.

 

Shield them from harsh weather

Mini greenhouses are great for shielding your plants from bad weather. Keeping them in an enclosed space protects them from snow, frost, drought, heavy rain, and high winds. They’ll continue to grow happily inside your greenhouse until it’s time to transplant or pick them.

 

Final Thoughts on How to Pinch Dahlias

By pinching your dahlias, you’ll notice a significant improvement in the growth of your plants. You’ll see more lateral shoots that grow into long, upright stems. The flowers that will bloom on these stems will be perfect for bouquets and arrangements.

Once you know how to pinch dahlias, you can enjoy longer-lasting blooms for months! After cutting your stems and flowers, place them in a plastic container with a few inches of boiling water. Let them cool for about an hour. This process can prolong the life of your dahlias and they can last up to a week in your vase, but make sure to change the water every few days.

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.

 

Conclusion

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.
