How Is Grass Pollinated

Gardener or not, curiosity will have you wondering, “how is grass pollinated?” and a quick answer to this is via the wind. Grasses belong to the family of Poaceae with an extensive list of 10,000 species. They depend on wind pollination to reproduce, and you must understand some underlying questions with this process if you want to grow them. 

While some consider grasses a problem in the greenhouse and garden, we humans benefit from their other members. They include edible food sources such as rice and wheat, ornamental grasses for landscaping, and those that we use as materials for furniture and houses. Learning how grasses pollinate will help you grow them efficiently and take advantage of their benefits. 

 

How Is Grass Pollinated

How Is Grass Pollinated: Is There Only One Way?

Grasses undergo wind pollination. The simplest explanation for this is because these crops can’t use seeds efficiently compared to other species. Grasses can produce many flowers, but there’s a low chance of these flowers becoming seed sources. 

With this in mind, it’s not surprising that gardeners face problems with inadequate pollination and productivity. And while some cross-pollinate their grasses, it would be more sensible to understand wind pollination to prevent losses when growing these plants. 

 

Wind pollination of grasses

Grasses undergo wind pollination as you would expect with species that have green flowers without sepals or petals. Another telltale sign that the species depend on wind pollination is if its flowers lack scent and color that otherwise attract insect pollinators. The parts are also more adapted for catching wind and pollen instead. 

This is because survival depends on how much pollen the plant can produce and if it has structures that can aid in carrying the pollen at a great distance. You may notice how grass flowers have large anthers and feathery stigmas to make up for more effortless reproduction. Remember that the anthers produce the pollen, while the stigmas capture the pollen. 

 

When do grasses pollinate?

Grass pollination mostly starts in May, but this varies depending on the species. For example, some grasses will only produce pollen from summer to fall, but some plants pollinate in spring. It’s also notable that pollination can occur earlier in the year if the spring is warm, but will happen later if the spring is cool. 

Instead of relying on a specific season, it will be easier to understand a typical grass pollination pattern. For example, it can take 4 to 10 days for pollination to spread on a cluster of flowers. The releasing of pollen starts with the proximal flowers and then ends with the distal ones. 

Therefore, if you’re wondering how long pollination can occur in a grass field, it can take 21 days or more. More so, dry weather can shorten this period, and cool weather will lengthen the pollination. Remember that high temperatures affect grass pollen viability, so it’s at its peak in the morning and gets low in the afternoon. 

 

 

What affects grass pollination?

As previously discussed, the temperature affects grass pollination, as it extends or shortens the period and dictates how early or how long until pollination starts. This can mean a change in the number of days or weeks from the pollination last year or when the pollen will be highly viable. However, you can assume that stress from humidity, drought, and nitrogen supply will also influence pollination.

The greenhouse can be a useful tool in the pollination of grasses since studies have shown the use of glazed paper bags and its positive effects in the pollination of grasses. You can also protect the crops from low humidity, drought, and rainfall, reducing seed yield and pollination using the greenhouse. 

 

How do grasses reproduce?

Before you get confused, grasses can still undergo sexual reproduction via seeds, and gardeners can cross-pollinate them as well. You can also reproduce grasses using stolons, rhizomes, nodes, and buds in vegetative propagation. But if you want to focus on self-pollination and cross=pollination, there are some considerations.

Not all grasses are self-compatible, but some have cleistogamous grass florets like cereal grains that will easily undergo self-pollination. On the other hand, cross-pollination is possible for monoecious and dioecious grasses, but not for dichogamous species. Lastly, the plant should have a chasmogamy system if you want to have species that allow both self-pollination and cross-pollination.

 

Conclusion

Learning about the reproduction of plants is key to having an efficient garden. But if you have grasses, you might wonder how is grass pollinated in the absence of insects. You’ll notice that the flowers in grasses are not colorful and scented to attract insect pollinators, but instead, they have defined structures.

If you put these observations altogether, you can assume that grasses utilize wind pollination. They produce a high number of pollen that should survive long distances to guarantee production. However, it’s still worth noting that some studies and gardeners use seeds and cross-pollination for grasses.

The only advantage with learning wind pollination is it’s easy and somewhat reliable, with less room for errors in the gardener’s side. More so, you can use a greenhouse to protect the grasses from factors that affect pollination. After all, the period length and when pollination starts to depend on conditions such as temperature, humidity, and rainfall.

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.
