How Cold Can Mums Tolerate

Since fall is just around the corner, you probably wondered, “How cold can mums tolerate?” The bright colored mums, pumpkins, and fall leaves are the symbol of fall.

These mums can grow through the winter, but their after-winter growth may be affected. Additionally, the level of protection your mum need from the cold depends on the climate. If you want to know how your mums will fare in varying temperatures, here’s what you should know:

How Cold Can Mums Tolerate

Warm Temperatures

Mum can generally survive warmer temperatures as long as they get enough water. However, heat tolerance usually varies depending on the type of species.

If you live in scorching areas with temperatures ranging from 90 to 100 degrees F, it’s best to plant them in a place where they’ll get some shade during the afternoons. Additionally, it may also be better to plant cultivars that can tolerate heat.

Mum bloom in cold nights, so if the nighttime temperatures are above average in your area for weeks, expect to experience delays in blooming.


Cold Temperatures

Mums are hardy throughout USDA zones 5 to 9, but this can vary depending on the type of species. If we look at the USDA map, you’ll find that mums can survive around (at the lowest) 20 degrees F below zero. This only applies to mums to garden hardy mums with well-established roots that have been planted during the spring season.

Most people plant mums in their gardens just in time for them to bloom during the fall. Keep in mind that mums that are planted in cold winters will not survive because of their shallow roots. If you plant mums in pots, they’ll are more likely to survive as the pots protect them from the cold.


How to Take Care of Your Mums During Winter

To take care of your mums during winter, be sure that you plant your flowers in well-drained soil. Mums are hardy plants, so it isn’t the cold that usually kills them, but it’s when the water in the roots turn into ice. For this reason, it’s essential to plant mums in well-draining soil.

Place your mums in a partially sheltered location to keep them safe from winter winds. Better yet, you can keep them inside a greenhouse to increase their chances of surviving through the winter.

It’s important to properly insulate your mums during the fall season. Once you notice that the leaves have died back after a few touches of frost, you need to cut the stems back at around three to four inches off the ground. Leaving a part of the stem ensures that you’ll have full, healthy mums next year. The shorter you cut the stems, the fewer the regrowth.

As you’re wintering the mums, add a thick layer of mulch (like straw or leaves) over your plants when the ground is frozen. This helps to further insulate your plants and prevents it from thawing. It’ll do more harm than good if the soil repeatedly freezes and thaws. It should remain frozen throughout the winter season.


Why Plant Mums in a Greenhouse?

Planting mums in your backyard is a great idea to spruce up your garden during the winter. However, not everyone has space or the right growing conditions to grow mums. If this is the case, having a mini greenhouse can save the day. Here are a few reasons why you should plant mums in a greenhouse:


Protect your plants from pesky insects

Chrysanthemum aphids, chrysanthemum leaf miners, and two-spotted spider mites are some of the insects that can destroy your mums. Keeping them inside a greenhouse protects them from these harmful insects. Additionally, your plants will also stay safe and protected if there are any infectious plant diseases.


Protect your mums from frost

As you know, mums are hardy, but it’s best to keep them away from frost and freezes. If you don’t want your mums to be subjected to low temperatures, you can protect them by placing them inside a greenhouse or a sheltered area if they’re planted in pots. If you planted them directly into the ground, you could cover them with a sheet board or cardboard.


Start plant growth earlier

Having a mini greenhouse allows you to start growing mums even before the cold season begins or during the cold season. A temperature-controlled greenhouse allows you to alter the climate inside to suit the plants’ specific needs. Once the weather becomes more favorable, you can carefully transplant your mums outside.


Perfect for tender perennial plants

Did you know that mini-greenhouses are great for tender perennial plants as well? Placing your plants inside a greenhouse protects them from frost and snow during the long winter season.

You can transplant them from the garden into pots and keep them inside until spring. Once the weather warms, you can transplant them back into the garden again.


The Bottom Line: How Cold Can Mums Tolerate

So, how cold can mums tolerate? Mums are fairly hardy plants, and they’re relatively easy to grow. If you’re planning to plant mums and have them bloom in the fall season, make sure to keep the tips above in mind for successful planting.

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.
