The saint herb (Santolina) is a perennial whose splendor you can easily multiply yourself. You have the choice between simple or complex.The Holy Herb (Santolina) is an uncomplicated bedding plant that looks very good in the rock garden, but can also be used to green roofs. The plants are easy to care for and bring a welcome splash of color into every bed with their sun-yellow flowers. The daisy family also thrives in otherwise unfavorable locations. The proliferation of the pretty, Mediterranean perennial, which is often still a rarity in our gardens, is definitely worth it. In the following, you will learn how the holy herb, also called the gray saint flower, can be propagated and how you can cultivate the young plants so that you can quickly enjoy lush growth and abundant flowering.
Increase Holy Herb - Possibilities
❶ Increase holy herb through cuttings
Propagation by cuttings is the most common way to propagate the saint herb. Cuttings are preferably cut in spring. In theory, cuttings can be cut into the summer. The shoot tips should have a length of between 15 and 20 centimeters. The lower leaves, which would be under the soil after planting, must be removed so that there is no rotting. The cuttings should not have flowers and should not be too woody. After cutting, the cuttings are placed in small planters. Use low-nutrient substrate for cultivation.
➔ Tip: You can put several cuttings in a plant pot, then the young plants will grow bushier.
In order for roots to form, a relatively high level of humidity is required. You can achieve this if the planters are covered with foil.
➔ Important: The foil cover must be ventilated regularly. Otherwise mold can form in the planter.
The planters are placed in a bright and warm place. The temperatures should be around 25 degrees. Now patience is required for a few weeks. Check the plant pots regularly and keep the soil evenly moist. Even if the holy herb is used to dryness, the young plants need even moisture to allow the roots to develop. If the first shoot tips show up, this is also the proof of successful cultivation. If the roots have penetrated the planter, the young plants should be transferred to larger pots. The planters are kept in the warm room until spring. From mid-May, the young plants can be placed outdoors, or alternatively in the tub.
Multiplication of cuttings step by step
- Cut the cutting
- Prepare the cutting
- Put the cuttings in plant pots
- Cover the planter with foil
- Place the planter in a bright and warm place
- Water the cuttings regularly
- Wait for germination
❷ Holy herb increase by division
Multiplication is a very popular method because you get whole plants straight away. However, division of the Holy Herb is only recommended every 10 to 15 years. Spring is a good time to divide the plant. To be able to divide the plant, it must first be completely removed from the ground. Care must be taken to ensure that the roots are not damaged. If you have taken the plant out of the soil, shake the soil gently so that the root ball is clearly visible. Now the root ball is cut with a spade. Depending on the size of the plant, different sections can be obtained.
➔ Tip: Each section should have enough roots and if possible have several shoots.
The division of the Holy Herb also offers the opportunity to examine the plant more closely. Sick or damaged root parts should be removed. The plant is then immediately planted in its new location. So that the holy herb roots well, water the plant lightly.
Multiplication by division step by step
- Dig up the plant
- Control roots
- Split root balls
- Transplant sections again
❸ Increase Holy Herb by lowering
The plants grow upright as well as lying down. As a result, the holy herb can also be propagated well by lowerers. It is an old gardening method, which is somewhat more complex than the above-mentioned possibilities of propagation, but promises very good chances of success.
First choose a shoot that is elastic enough and can be bent down to the ground. The shoot must not kink and must remain in contact with the mother plant. An elongated furrow is dug on the ground, which can take up the shoot. This groove is filled with earth. The shoot tip can be seen from the ground. The shoot tip can be tied to a wooden stick so that it grows upright. So that the shoot does not develop too much tension and shoot out of the ground, weigh down the filled furrow with stones. After a few months the shoot will have new roots in the soil and can be separated from the mother plant and replanted.
➔ Tip: The formation of new roots is accelerated if you gently scratch the shoot in several places with a knife.
Multiplication by lowering step by step
- Select shoot
- Dig out furrow
- Bend the shoot towards the ground
- Introduce the shoot
- Cover the shoot with soil
- Let the spike look out
- Complain furrow
- Fix shoot tip for upright growth
- Wait for rooting
❹ Increase Holy Herb by sowing
If you do not yet own a saint herb yourself, propagation by sowing will probably be of interest to you. Numerous young plants can be obtained with very simple means. The seed can be purchased commercially or you know a hobby gardener friend who will give you some seeds. The seeds are first dried. Then put the seeds in a closed container and store in a cool and dry place until spring.
Since the holy herb is one of the cold germs, cold treatment will be necessary before sowing. Soak the seeds in lukewarm water for about 24 hours. Then the seeds go into a plastic bag. Add some sand and close the bag well. The plastic bag is placed in the refrigerator for about a month. After this cold treatment, the seeds can be sown in a planting bowl. The seeds are not covered with earth and are only lightly pressed on. When a few weeks have passed, the first cotyledons will appear. If there are several pairs of leaves, the plantlets are separated. When there is no more frost, the young plants can move outdoors.
Propagation by sowing step by step
- Dry seeds
- Store seeds
- Water the seeds
- Cool the seeds
- Sow seeds
- Wait for germination
