How to propagate Portulaca grandiflora? A detailed guide to sowing and cuttings methods

Portulaca grandiflora is a fairly common plant in people's daily lives. It originated in South America and was later introduced to China. As for how to propagate Portulaca grandiflora, it can actually be divided into two methods: propagation by sowing and propagation by cuttings. As long as the method is right, the survival rate is fairly high. If you want to know the propagation methods of Portulaca grandiflora, you can read on with the editor below.

I. How to propagate Portulaca grandiflora / sowing / cuttings

The propagation methods of Portulaca grandiflora can be divided into two types: sowing and cuttings, and the two propagation methods are also very different. However, as long as the methods are mastered correctly, the survival rates of both propagation methods are very high. The specific propagation methods are described below, so let's continue reading.

II. Propagation methods of Portulaca grandiflora

Propagation by sowing

1. Sowing time

When propagating Portulaca grandiflora by sowing, it is best to choose the two seasons of spring and summer, because the climate in these two seasons is more suitable for Portulaca grandiflora and very favorable for its growth. When propagated in these two seasons, it generally sprouts in 5-7 days.

2. Sowing method

Portulaca grandiflora prefers a warm climate, so when choosing soil, it is best to choose soil that is relatively drought-tolerant. The seeds of Portulaca grandiflora are relatively small, so when sowing, you can choose to mix them with fine sand for sowing, with a ratio of 5:1.

Propagation by cuttings

1. Container selection

When propagating Portulaca grandiflora by cuttings, we should choose a container whose bottom can drain water, as this will be more favorable for its growth. For the cutting time, we can generally choose the period from May to August each year, because the environment is suitable, so it will greatly increase the survival rate of Portulaca grandiflora.

2. Cutting method

When taking cuttings, be sure to water the potting soil in advance, because the cuttings of Portulaca grandiflora are relatively tender, and soil that is too dry can easily cause damage. The depth for inserting the cuttings should not exceed 2cm, as this will be more favorable for its growth. After the cuttings are completed, they generally become established in 10-15 days.

In fact, the propagation methods of Portulaca grandiflora are still relatively simple. As long as everyone pays attention to the above points, success is basically possible. After saying so much, I believe everyone has gained a certain understanding of the propagation methods of Portulaca grandiflora. Now is also a good season for cuttings, so everyone can take action.

Sowing and cutting propagation methods for Portulaca grandiflora

Portulaca grandiflora is also called Longxu peony, sun flower, etc. Because Portulaca grandiflora has many flower colors and a long flowering period, its ornamental value is also relatively high. Now, Portulaca grandiflora is often propagated by sowing and cuttings, so how exactly should it be done?

Portulaca grandiflora

1. Sowing: Seed germination requires a temperature above 20°C, and sowing is usually done in early April. It can be sown in an open-field seedbed or directly sown in a pot. Because the seeds are extremely small and light is favorable for germination, after sowing it is advisable to cover with a thin layer of soil or not cover with soil. The suitable temperature for germination is 21-24°C, and germination can occur about 7 days after sowing. When the soil temperature is about 21°C during the day and 16°C at night, the seeds germinate faster and the seedlings emerge neatly, but initial growth is very slow. Direct-sown plants need 2 and a half months to bloom. The seeds have strong vitality and can still sprout after being stored for 3-4 years. It has a strong self-seeding ability. Once planted, as long as the potting soil is kept moist, new seedlings will grow every spring.

2. Cuttings: Usually used for propagating double-petaled varieties. It is often done in summer. Cut healthy branch tips as cuttings, with a cutting length of 5-6 cm, and insert them into a seedbed or directly into a pot, 3-5 per pot. Open-field cuttings must avoid rain, otherwise the cuttings are prone to rot. Generally, roots can form 10-12 days after insertion, and they are very easy to establish, and after establishment they can bloom.

Propagation methods and management of Portulaca grandiflora

Portulaca grandiflora is also called sun flower, because its flowers open when there is sufficient sunlight and close when the light is weak, such as on cloudy days and from evening to early morning. Because the flower shape of Portulaca grandiflora resembles a peony and its leaves resemble pine needles, it also has the alternative names Longxu peony or Songye peony.

Portulaca grandiflora

Portulaca grandiflora is generally propagated by sowing or cuttings, sown indoors in a sunny spot in March or directly sown in the courtyard in April. The suitable temperature for seed germination is 20-25 degrees, and sprouts can appear in about 1 week. After the seedlings emerge completely, with a little thinning or transplanting, they can bloom in about two months. During the growth period, tender stems can be picked for cuttings, which root easily and bloom quickly; after transplanting, they recover growth very easily, so large seedlings can also be transplanted bare-root. The main flowering period is from July to September, and the small capsules mature from August to October. The fruit, shaped like a melon-rind cap, splits horizontally when mature and immediately scatters tiny silver-gray seeds. Some corollas have already fallen off, and when the top cover of the capsule is wheat-straw yellow, it is also already mature; pay attention to timely harvesting.

Portulaca grandiflora is a cross-pollinated plant, and propagation by sowing makes it difficult to maintain variety purity. For seed collection, pay attention to eliminating single-petaled and small-flowered plants.

At home, it is mostly grown in shallow pots on windowsills and balconies, cultivated into delicate and exquisite small potted flowers.
