How To Propagate Agastache. 3 Best Ways

You can choose from three methods if you’re interested in how to propagate agastache. Agastache or hyssop has different varieties that will surely get your garden to look more lively in summer and fall. And best of all, you can propagate this plant either from seeds, cuttings, or division. 

Perhaps this flexibility in propagation has inspired many gardeners to venture into the commercial production of agastache. But regardless if you’re growing for profit or hobby, take comfort in the fact that growing agastache itself is not meticulous. Those who have a greenhouse can start their agastache indoors and guarantee plants’ establishment without drawbacks from fluctuating weather conditions. 


How To Propagate Agastache. 3 Best Ways

How To Propagate Agastache Successfully


Method #1. Seeds

Experienced gardeners recommend starting agastache seeds in the greenhouse. This will guarantee germination and protection from the potentially harsh climate. Plant your seeds indoors around six weeks before your location’s last frost date, which can be around February to March for transplanting in May. 


Starting seeds indoors

You can use a general seed starting mix, but make sure that it is moist. Cover the seeds as you would when starting other plants and maintain soil moisture and temperature at 55°F. Once the seedlings are around 4 inches tall, you can transplant them in May, either in containers or at the garden with 12 inches of space between each plant. 


Starting seeds outdoors

If you are confident about the weather, you can also sow the seeds directly in the fall since they will go dormant in winter. Once the plants have developed four leaves, you can thin them to a foot apart. It’s crucial to protect the plants from extreme conditions, and it’s worth noting that they will bloom later than transplants, so choose a sowing time wisely. 


Method #2. Cuttings

Some agastache plants will propagate from cuttings instead of seeds. As you can assume, starting agastache from either cuttings or divisions will produce plants true to the parent plant. You can also take them yourself from a plant you fancy as long as it is healthy to withstand the cutting process. 


Collecting cuttings

The good thing about agastache is that you can propagate it either from softwood or semi-hardwood cuttings. Collect the cuttings when the plant is about to bloom and abundant with new growth. A useful tip is if a shoot snap, you can harvest cuttings. 

The ideal shoots are those with different types of leaves. Some might be mature, but some might still be growing. You want to take cuttings close to the crown at varying parts of the plant so that the agastache maintains its appearance. 



Once you have the cuttings, please place them in rooting hormone powder and use a seed-starting medium. Maintain moisture and soil temperature between 68 to 75°F to encourage rooting around ten days. More so, heat around 70 to 75°F at the bottom of the container is optimal for root development. 


Method #3. Division

The final propagation method for agastache is by division, which is also useful for maintaining the plant. In general, this allows gardeners to create more plants from mature hyssop that are starting to outgrow its location. Quite similar to propagation from cuttings, the best time to divide agastache is when it’s developing new growth in spring. 



You also want to divide when the temperature is cool to prevent the roots from undergoing stress due to the afternoon’s heat. More so, the divisions will have already settled when the day gets hot if you divide early in the morning. Dig up the entire plant and decide if you want to split the clump in half if it is too big. 


Separating and establishment

Once you have the clump, you can separate it into sections by hand. Gauge the size of each section so that they have enough roots for establishment. You can choose to start these divisions in the greenhouse or immediately at the garden as long as the location is bright and the soil is well-draining

You can encourage the establishment of the divisions by immediately watering them upon planting and ensuring soil moisture until they grow. If you grew agastache divisions indoors in containers, remember that they will dry faster. Nonetheless, be careful not to overwater agastache during propagation and after establishment.



Whether you want to grow more hyssop plants for your garden or business, you can take advantage of the greenhouse and start your plants indoors to guarantee productivity. Learning how to propagate agastache introduces many opportunities to start the plant from seeds, cuttings, or divisions. 

Starting agastache seeds indoors will have your plants blooming faster than directly starting them in the garden. You also have a higher rate of germination because the indoor conditions are supportive of the seeds. But if you want to create clones of your favorite agastache plants, you can also use the greenhouse for propagating cuttings and divisions. 

Propagating agastache from cuttings and divisions are no different from other plants. Take cuttings or divide when the plant develops new growth and ensure moisture until they root and establish themselves. However, note the type of agastache you have since it may have a specific propagation requirement to develop.

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.
