How to Propagate Gardenia? Introduction to Gardenia Propagation Methods
Gardenia can be propagated by many methods, both sexual and asexual reproduction. Generally, cuttings and layering are most commonly used; division and sowing can also be used but are rarely adopted, as potted plants in the north generally do not easily set seed. Let us take a look below at the propagation methods for gardenia!
Gardenia Propagation by Cuttings
The cutting method can be divided into spring cuttings and autumn cuttings. Spring cuttings are taken in mid-to-late February, and autumn cuttings from late September to late October. There are slight differences between the north and the south, but the survival rate is highest between summer and autumn. Select healthy 2- to 3-year-old branches as cuttings, cut them to 10-12 cm, remove the lower leaves, keep the top two leaves and cut each in half, first dip in vitamin B12 injection, then insert diagonally into the cutting bed with only one node left above. Pay attention to shading and maintaining a certain humidity.
Rooting generally occurs in about 1 month; under 80% relative humidity and a temperature of 20-24°C, it takes about 15 days. Soaking in 20×10(-6th power) to 50×10(-6th power) indolebutyric acid for 24 hours gives even better results. When the rooted seedlings begin to grow, transplant them or pot them individually; they can bloom after 2 years. In the south, water propagation is also used, that is, inserting the cuttings into a disc woven from reed stems and letting it float on the water surface so that the lower part roots in the water, then transplanting for cultivation.
Gardenia Propagation by Layering
This is generally done around Qingming in April or during the plum rain season. In April, select 1-year-old vigorous branches 25-30 cm long from a 3-year-old mother plant for layering, pull them to the ground, and wound the part of the branch that enters the soil. If the wounded part can be dipped in 200 ppm powdered naphthaleneacetic acid and then covered with soil and pressed firm, rooting is even easier. If there is a three-forked branch, three seedlings can be obtained at once from the fork. Rooting generally occurs in 20-30 days; after rooting in June, they can be separated from the mother plant, and by the following spring they can be transplanted with soil or potted individually.
For transplanting seedlings or potting, spring is best, carried out during the plum rain season, and a soil ball is needed. Keep the soil moist during the growing period, and water more during the flowering period and midsummer. Fertilize once a month, and add one extra application of phosphorus and potassium fertilizer before flowering. In early spring of the following year, prune and shape, and promptly cut off dead branches and leggy branches.
Gardenia Propagation by Sowing
Generally choose plump, deep-red ripe fruits, dry them in the shell in the sun or in the shade for seed. Before sowing, cut open the seed coat with scissors, dig out the seeds, rub them apart in hot water, remove floating seeds or impurities, then scoop out the sunken plump seeds, spread them on a bamboo mat, and place them in a ventilated place to dry off excess moisture. Generally choose a sunny hillside or earthen plot with deep, loose, fertile sandy loam for sowing; field edges and corners can be used for planting, or intercropping with legumes. Before planting, plow the land 1-1.5 chi deep, remove stumps of miscellaneous trees, and make beds with a bed surface width of 4-5 chi (the spacing can be larger if the soil is good, otherwise smaller), with a bed height of 6 cun. Apply farmyard manure, green manure or human and livestock manure water as base fertilizer, for example 20-30 loads of human waste per mu. After the soil dries, shallowly rake the clods and level the bed surface. Open sowing furrows on the bed surface at 6-7 cun row spacing, with a furrow depth of about 1 cun, ready for sowing.
Gardenia can be sown in spring or autumn, generally mostly in spring. Spring sowing is done around Yushui, and autumn sowing around Qiufen. When sowing, mix the seeds with wood ash and evenly sow them in the sowing furrows, then cover and level the furrows with fine soil or burnt soil, cover with grass and sprinkle water, and keep the soil moist regularly to favor seedling emergence. Use 4-6 jin of seed per mu. After emergence, promptly remove the covering grass, weed frequently during the seedling stage, and be careful not to damage the seedling roots. After weeding, topdress with dilute human waste water. After one year of raising seedlings, they can be transplanted. If transport is relatively far, it is best to coat the roots with yellow mud slurry, cover with grass to retain moisture, plant one plant per hole, then cover with soil, press firm and sprinkle water. After planting, carry out one cultivation, weeding and topdressing each spring and summer, applying human and livestock manure, barnyard manure, compost, cake fertilizer, etc. Before flowering in summer, fertilizer with higher phosphorus and potassium content is best; fertilizing is generally done after weeding and loosening the soil.
Gardenia Propagation by Water Cuttings for Rooting
Take 10-12 cm long 1-year-old branches and keep 2-4 leaves. Cut the tip of the branch into a horse-ear shape, soak it in 0.1% potassium permanganate solution for 4-6 hours, then take it out and insert it into clean water, with the submerged length being 1/3 of the total cutting length. Use a brown bottle as the container and change the water once every 1-2 days. Alternatively, drill small holes in a wooden board or foam board, insert the cuttings into the holes, and then float it on the water surface, where 2/3 of the cutting length needs to remain above the floating body and 1/3 inserted into the water.
After the gardenia grows new roots, move it from a darker place to a bright place. When the roots grow to 1.5-2 cm and a single plant has 6-7 roots, it can be transplanted into a pot or planted in the ground.

Gardenia can bring a qualitative change to the home environment. The greatest feature of a gardenia is its floral fragrance. As long as one is planted at home, it can be smelled within a radius of several hundred square meters. Just imagine, in your home, with a space of about over one hundred square meters, you can smell the scent of gardenia no matter which corner you walk to. Many homeowners wonder whether they can avoid buying a mature plant and let the gardenia propagate on its own. Today, the editor will solve this problem for everyone. Today, the editor will introduce how to propagate gardenia and the propagation methods for gardenia, hoping to be of help to everyone.

Gardenia is also known as Zhizi. Its leaves are deep green and its floral fragrance is elegant. It can be grown as a potted plant for ornamental purposes, and the flowers can also be used in flower arrangements and worn as decoration. Therefore, gardenia can be seen in many courtyards and homes. So how do you propagate gardenia? Today, let us talk about gardenia propagation methods.
1. Cutting method
Gardenia branches root very easily. In warm southern regions, cuttings are often taken from March to October, while in the north they are usually taken from May to June. Cut vigorous mature branches and insert them into a sand bed; as long as they are kept moist regularly, they root and survive very easily. Water cuttings are far superior to soil cuttings, with a survival rate close to 100%. Carried out from April to July, cut the cuttings and keep only the top 2 leaves and the apical bud, insert them in a container filled with clean water, and change the water frequently to prevent the cut from rotting. Rooting begins after 3 weeks.
2. Layering method
This is generally done around Qingming in April or during the plum rain season. In April, select 1-year-old vigorous branches 25-30 cm long from a 3-year-old mother plant for layering, pull them to the ground, and wound the part of the branch that enters the soil.
