A member of the mint genus Agastache, widely known as Sunset Hyssop, Agastache rupestris is a stunning and useful plant. Despite the fact that it is one of the few hyssops that can be grown from seed, it can also be propagated by cuttings of both semi-hardwood and softwood varieties. With its abundance of bronze and yellow flowers atop blue-green foliage in late summer, the Sunset Hyssop thrives even in the most difficult soils. Picking this showiest bloom when the buds are only slightly open is your best bet for propagation.
Snip some fresh shoots and test their readiness to harvest. If the shoots snap like green beans, they’re ripe. As soon as buds begin to appear, keep an eye on the plant every week, and be ready to take cuttings when they are ready.
Make sure to choose shoots with leaves in various stages of development, some still very little and others practically mature. Maintain the plant’s look by snipping off the young branches near the top at various points around the plant.
Rooting hormone should be applied to the cuttings immediately, and they should be placed in a moist seed-starting medium such as peat, sand, vermiculite, or perlite.
Where to plant Agastache
An acidic, alkaline, or neutral pH balance is excellent for growing Agastache. It can be be grown in soil that is damp but well-drained. They are drought-resistant plants that thrive in full light and should be placed there. Cottage, informal, and wildlife gardens benefit greatly from the inclusion of Agastache in flower beds and borders because of the plethora of bees and butterflies they attract.

How to plant Agastache
Add plenty of organic materials to the planting area and properly mix it to enhance drainage.
How to care for Agastache
Keep your plants well watered while they are young, then reduce the amount of water as they become older. Agastache can produce more flowers if it is started indoors in late April and then moved outdoors in early summer.
How To Propagate Agastache Successfully
Method #1. Seeds
Agastache seeds should be started in a greenhouse, according to seasoned gardeners. This will ensure that the seeds will germinate and that they will be protected from the adverse weather conditions that may come their way. If you live in a place where the last frost date is in February or March, you should start your seeds inside six weeks before that date.
Starting seeds indoors
However, you must ensure that the seed starting mix is wet. Keep the soil moist and the temperature around 55 degrees Fahrenheit while starting the seeds as you would any other plant. The seedlings can be transplanted in May, either in pots or at the garden with a 12-inch spacing between each plant.
Starting seeds outdoors
Sowing seeds in the fall, knowing that they would go dormant in the winter, is an option if you are confident in the weather. You can thin the plants to a foot apart once they have four leaves. If you don’t protect your seedlings from harsh conditions, they will blossom later than transplants, so plan your sowing schedule accordingly.
Method #2. Cuttings
Cuttings can be used to propagate some agastache plants instead of seeds. Starting agastache from cuttings or divisions will result in plants that are identical to the parent plant, as expected. As long as the plant is healthy enough to resist the cutting process, you can take them yourself.
Collecting cuttings
Agastache may be grown from either softwood or semi-hardwood cuttings, which is a positive feature. The best time to take cuttings is when the plant is just starting to bloom and has a lot of fresh growth on its stems. In the event that a shoot snaps, it is possible to collect cuttings.
Shoots with a variety of leaves are desirable. Some may be mature, but others may still be developing. Keeping the agastache’s look by taking cuttings near to the crown is important.
Rooting
A seed-starting medium should be used with rooting hormone powder once you have the cuttings. In order to enhance roots, keep the soil temperature and moisture between 68 and 75 degrees. In addition, a temperature of 70-75°F at the container’s bottom is ideal for root development.
Method #3. Division
Finally, agastache can be propagated by division, which is extremely important for preserving the plant’s health and appearance. Most gardeners can use mature hyssop that has outgrown its current place to produce additional plants by cutting it back. The optimum time to divide agastache is in the spring, when it is beginning to grow new leaves.
Digging
To avoid damaging the roots from the heat of the afternoon, it’s best to divide your plants when the temperature is cooler. Moreover, if you divide early in the morning, the divisions will be decided by the time the day heats up. Determine if you want to split the cluster in two if the plant is too large before digging it up.
Separating and establishment
Once you have the clump, you can break it apart by hand. Make sure each portion has enough roots to grow into a full-fledged tree. As long as the place is well-lit and the soil is well-draining, you can begin these divisions in the greenhouse or in the garden right away.
You may help the divisions grow by watering them immediately after planting and keeping the soil moist until they are established. Keep in mind that agastache divisions grown indoors in containers will dry out faster. Nevertheless, you should use caution when propagating and establishing agastache and avoid overwatering it.

Production
For Acapulco Deluxe, it’s recommended to use 1-gallon or smaller containers. It’s best to grow them in a medium with a pH between 5.8 and 6.2, which drains nicely. A wide variety of growing mediums can be used, but avoid ones with a high water holding capacity. The liners should not be planted too deeply; instead, they should be planted so that the original soil line of the liner is even with the surface of the growing medium in the new container.
Overwatering Agastache will cause root rot and poor performance because they dislike damp feet. A lack of growth and yellowing are signs that too much water is being used. Allow the soil to dry moderately between irrigations when watering is necessary. In spite of its drought tolerance in the landscape, mature Mexican hyssop plants planted in containers should not be allowed to become extremely dry.
Light-to-moderate feeders, they are. Water-soluble and controlled-release fertilizers can be used to give nutrients to plants. Water-soluble fertilizers can be applied at 100 to 125 parts per million nitrogen per irrigation or at 200 parts per million if necessary. At a rate comparable to one pound of elemental nitrogen per yard of growing medium, controlled-release fertilizers are typically added to the soil prior to planting. Soft growth and delayed flowering are common side effects of using excessive levels of fertilizer.
As soon as the plants have acquired a foothold, a little pinch one to two weeks after planting can be helpful. Larger containers may necessitate an extra pinch of effort.
No height management methods are needed for Acapulco Deluxe. The spacing between plants and the amount of light they receive can help control unwanted stem elongation. Spray applications of 2500-ppm daminozide, 2500-ppm daminozide + 1250-ppm chlormequat chloride, 30 ppm paclobutrazol, or 5 ppm uniconazole are recommended if the plants need to be toned.. One application is usually sufficient in the majority of cases.
Diseases Caused by Insects and Other Pathogens
Insects and illnesses are rarely a problem when growing Agastache. It’s not uncommon for thrips and whiteflies to show up in the field, causing only modest crop damage. Growers are more concerned about Pythium and Phytopthora. These infections can be avoided by planting the liners correctly and by using adequate irrigation procedures.. Botrytis, downy mildew, Heterosporium leaf spots, and rust are some diseases to look out for. Routine scouting activities can help growers identify these pests and illnesses.
Scheduling and Temperature
Taking care of Acapulco Deluxe’s flowering plants at any time of year is simple. Flowering does not necessitate vernalization. If your plants have been overwintered, you should avoid over-watering them and make sure they have enough protection from the winter elements. Flowering occurs regardless of the duration of the day. When agastache is grown in bright light, it will produce more flowers, have better coloring, and be of greater quality overall.
Temperatures above 60°F at night and 65°F during the day create the greatest grade plants. The amount of time it takes for a plant to grow varies depending on the temperature and the size of the container. It takes six to seven weeks to grow 4-inch pots into marketable size, whereas 6-inch pots take nine to 10 weeks to flower at these temps

Conclusion
Grow more hyssop plants in the greenhouse, whether for your garden or business, to ensure a high level of productivity. The ability to grow agastache from seed, cuttings, or divisions is one of the numerous benefits of becoming familiar with propagation techniques.
If you start your agastache seeds indoors, they will bloom more quickly than if you start them outside. When you grow plants indoors, you can expect a greater germination rate. The greenhouse can also be used for propagating cuttings and divisions of your favorite agastache plants.
Agastache cuttings and divisions can be propagated in the same way as any other plant. When the plant begins to produce new growth, take cuttings or divide it and keep it wet until the cuttings root and become established. However, it is important to keep in mind the type of agastache you have, as it may require an unique propagation method to grow.
