Anise hyssop is a frost-tolerant perennial plant. They can survive in the winter.
Start growing them 2-3 weeks before the last frost to enjoy the bloom in the spring season.
Here what to do first:
Take a medium-sized pot of 6 inches in diameter. The pot should be wide enough so that the roots of the plant can spread deeply.
Make sure that the pot has adequate or sufficient drainage holes. Drainage holes help to flow out excessive water from the plant.
Plants need minerals and nutrition to grow. Use potting mix soil for gardening. You can also mix some organic compost in the soil to increase its quality.
Adding organic compost to the soil is a good investment as it will save you to feed with fertilizers in the growing season.
Put 2-3 seeds in the center of the pot and press them onto the soil. Sowing more seeds in a limited space pot makes it crowded.
Do not use dry or old seeds, it takes more time to germinate and even does not germinate.
Pour water to keep the soil moist. Plants like moist soil but do not like to stand in the water. Overwatering causes lots of problems in plant growth.
You can add mulch on the surface of the soil. Mulch helps to keep the soil moist for a longer time and requires less frequent water.
Where to place the pot?
You should place the pot in a spot where it gets early morning sunlight and afternoon shade. The mid-afternoon sunlight is more harsh or intense as compared to the morning, it may burn young plant’s leaves especially in the hot summer.
When to transplant from the pot?
Anise hyssop is a large bloom plant that needs a strong and wide root system to stand.
They cannot grow to mature size in a pot or a container despite how wide and deep it is.
So, after a point you have to transplant them in a large garden area.
I recommend planting them when the seedlings become 5-6 inches.
In this stage the young plant’s root has not got too deep and strong which can be easily transplanted.
Take a grub hook, start tossing from the circumference or side of the pot and transplant it to a decided place.
You should plant them in a sunny and partial shade area (Discussed in where to place the pot question)
You can propagate these perennial shrubs by three propagation methods.
Let’s see them one by one:
Propagation from seeds is easy but their are some points to keep in mind
Always use fresh pairs of seeds. Sowing dried or old seeds might not germinate. You can buy fresh seeds from a nearby nursery or online store.
Sow only 2-3 seeds. Make a small hole in the soil and put 2-3 seeds. Sowing more seeds in a particular area will stunt the growth when plants mature.
Maintain some distance. When sowing seeds in the ground you should maintain nearly 6 feet of gap between each seed hole. This planting arrangement provides young plants enough area to take water and nutrition from the ground.
From stem cutting
Stem cutting is a common practice to propagate any plant. However, you have to do things correctly to get success.
Select any node stem and cut it using sharp shear. Do not tear or break the stem, it might leave damage on the plant.
Clear all leaves from the bottom half of the stem cutting and plant it to the ground.
Dip one end of the stem cutting in rooting hormone to have an addiction growth support. Using a rooting hormone is optional.
In the beginning, it might look wilt but after a couple of weeks, the stem starts rooting and slowly gets in shape.
Propagation from the division of the plant is a tricky method. You can create a hybrid by using these methods.
Here what to do:
Take a sharp shear and cut a stem from the plant.
Make the same cut on some other plant and join them together with a piece of cloth. Rap cloth around the cutting and join them.
After a few weeks, they get joined and start growing.
Plants or trees which are propagated from division generally do not produce seeds.
