Gardenias impress with their bright white and fragrant flowers. No wonder if amateur gardeners want to own more than just one plant. Here's the good news: growing gardenias is a breeze.
If you observe the attractive tropical plants in bloom, you may be thinking about looking after the flower window and increasing the gardenia (Gardenia jasminoides). It is worth pursuing this thought and not rejecting it in two ways. The pretty plants are definitely a win. In addition, propagation is less complicated than you might think in an exotic plant. You will now learn in detail how you can successfully multiply gardenia.
There are two ways to grow gardenias yourself:
- through cuttings
- through seeds
Propagation by cuttings
The best time for the rather uncomplicated method of propagating cuttings is spring. The cuttings should have several flowers and be cut directly below a knot.
" Tip: To promote rooting, the cuttings can be dipped in rooting powder.
The use of lime-free soil is very important when growing. A mixture of peat and sand to which compost has been added has proven particularly useful. The cuttings are placed in the substrate after the interfaces have dried briefly.
To create the ideal climate for rooting, the cuttings must be provided with plastic hoods. In a warm and bright location, it will take about a month for the first new shoots to show successful rooting.
Can cuttings be cut at a different time?
Some gardeners swear by cutting gardenia cuttings in late summer or late winter. Since the cut is made after flowering, the cuttings have no buds. The cuttings should be cut in a length of about eight to ten centimeters and root at about 25 degrees. With this method, rooting occurs in about three weeks.
The propagation through cuttings in key words:
❶ Cut the cutting
Lassen Let the interface dry
❸ use rooting powder if necessary
❹ Place the cuttings in a lime-free, nutrient-rich substrate
❺ Slip the plastic hood over the cutting
❻ Keep the cutting evenly moist
❼ Rooting takes place after about four weeks
Propagation by seeds
The propagation by seeds can be carried out all year round. The growing soil must be kept evenly moist. The seeds find the best conditions in a humid, warm climate. This can be improvised by covering the seed bowl with a film or plastic hood. A bright location and constant temperatures of around 24 degrees favor germination.
" Tip: So that mold does not form on the substrate, the cover of the seed pan should be aired daily.
Raising seeds is less reliable than propagating cuttings. Therefore, several seeds should be used in order to ultimately succeed. If the first shoots appear, successful propagation can be assumed.
What happens to the young plants?
Successfully propagated cuttings - and now?
If the cuttings sprout, they should be left in the original planter for a while, so that the roots become a bit stronger and are not injured when transplanting. Young plants are particularly sensitive in this regard.
Sufficiently strong young plants should have formed after about three months. Now transplant into separate planters. The plant pot should not be chosen too large. It is common to replant young gardenias several times in their first year. A warm and bright location is maintained. Watering is now a little less. The earth must not dry out and water must not form. If young plants are irrigated too intensely, the cuttings can quickly rot. The roots are particularly sensitive and cannot handle too much moisture.
Seeds successfully propagated - and now?
The propagation by seeds is a bit lengthy, but here the first instincts can be seen as a success. The seedlings are left in the seed pan until several pairs of leaves have formed. Now the strongest seedlings are picked out and put into their own planters. The further cultivation takes place, as already described for the propagation by cuttings.
