How To Grow Agastache Successfully


Step #1. Sowing


Germinating seeds

You can start agastache from cuttings as some gardeners mentioned it’s possible, but it’s easier and more common to use seeds for this plant. Take advantage of the greenhouse for starting the seeds, so you’re still on schedule but without the risk of frost. Sow agastache seeds in the greenhouse at eight weeks before the last frost date in spring. 

You can use a seed-starting formula as the medium and plant the seeds a quarter deep. Make sure that you maintain the soil moisture to encourage germination. Agastache seeds will also respond well to soil temperatures between 70 to 75°F, and you can wait for seedlings to develop after 21 days or less. 

While agastache seeds take time to germinate and develop, stable indoor conditions can help them grow as soon as 14 days. Be diligent in maintenance and keep them from harsh conditions. And once they’ve developed, you can transfer the seedlings. 


Maintaining seedlings

The seedlings will grow well under fluorescent lights. Ensure that they are 4 inches away from the source and have the bulbs on for 16 hours per day.  You can also start fertilizing and transplant the seedlings from cells to pots once they develop true leaves. 

At this point, you can harden the young agastache plants and transplant them in the garden. Remember that hardening plants are important before transplanting to avoid stress. Lastly, be wary of frost, and consider moving them indoors again if the nighttime temperatures are freezing. 


Step #2. Planting

A useful tip to remember is if the area is feasible for lavender plants, it will be suitable for agastache. Unlike other plants, agastache plants prefer soil that is alkaline and low fertility. They also tolerate drought, but be mindful of having good drainage, improving the soil quality if necessary. 

The location itself should be sunny, and you can prepare the ground as you would with other plants. The best time to plant is when it’s not sunny, as heat can lead to transplant shock. Gently remove the plant from its pot, loosen the root ball, and plant it in a hole that’s big enough for it. 


Step #3. Maintenance

After planting, you can lightly mulch the top of the soil to keep weeds at bay. This will also help in maintaining soil moisture and temperature, which are essential for plant establishment. Agastache plants can have water once a week when they are just establishing themselves but do so in the morning to guarantee that they’ll dry by evening. 

You can also use low rates of slow-release fertilizer to prevent rot and burns when you notice new growth. At this point, the young plants still need protection from challenging conditions. If your area is prone to having harsh sun or extreme winds, it might be better to keep the plants indoors or covered. 

Should you deadhead agastache? Agastache can benefit from deadheading, especially if you want to keep them in bloom. Removing the faded flower heads will help the plant focus its energy on flowering. 

And in fall, don’t forget to remove the foliage after the frost. 


Can You Divide Agastache?

You can divide your agastache early in autumn. This is an excellent practice to keep a tidy set-up when the plant is outgrowing its space. The process is straightforward, and you can treat it as you would when dividing other plants.

Dig the plant and pull it apart into clumps, ensuring that each section should have around three shoots and a root system to guarantee growth. The beauty of dividing agastache is that you can divide it every two to three years. Not only will it create a neater-looking garden, but you can replant these divisions to create more plants. 



If you want to have a garden that’s welcoming of pollinators, consider adding hyssops. Learning how to grow agastache is not difficult because there are no special requirements and steps for them. You start the seeds indoors to encourage germination and then transplant them outdoors once the climate is optimal. 

The maintenance of agastache is also relatively easy to provide. Water them when needed and feed with a slow-release fertilizer. You may also need to remove the spent blooms to encourage your plants to continue flowering. 

More so, you can divide agastache every two to three years and replant the clumps. This helps with cloning your favorite plants, but also in keeping a neat garden. Lastly, always check your outdoor conditions and use a greenhouse for protection when it’s too challenging.

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.
