Detailed Guide to Planting Bougainvillea and Points to Note

Flowers & Gardening 0 views
To plant bougainvillea, select a 20cm woody branch, remove the leaves at the bottom end, plant it into the growing medium, then cover with a layer of glass, and keep it in a ventilated, shaded place; after one month it can be exposed to sunlight. During the planting process, pay attention to moisture retention; you can spray and fertilize with an aqueous solution of monopotassium phosphate, and after it survives, transplant it into a pot. Note that when it first sprouts, do not rush to transplant it.

I. Planting Methods

Bougainvillea is mainly propagated by cuttings. In the north, cuttings are mainly taken in May and June, with 20-30°C being the suitable temperature. Select a one-year-old woody branch, cut about 20cm, remove the leaves near the lower end, and keep 2-3 leaves. Insert the prepared branch into a sand pot 4-6cm deep, then cover with glass to keep it warm; the first watering should be thorough. Place the cuttings in a ventilated, shaded place, and within 15 days sparse light can be allowed; after about one month, once roots have formed, full sunlight can be given. After two years of cultivation, it can bloom.

II. Care Measures

1. Light: Do not expose to strong light before rooting; after one month, it can receive light all day.

2. Moisture retention: If the weather is dry, cover with a glass cover or plastic wrap to retain moisture, and be sure to leave ventilation openings. In the evening, uncover for ventilation, spray water, and then cover again.

3. Fertilizing: During cuttings, foliar feeding can be applied, choosing a one-thousandth concentration aqueous solution of monopotassium phosphate, sprayed once every 10 days.

4. Potting: Harden off the surviving young seedlings under strong light and water with dilute fertilizer. At about 50-60 days after cutting, divide and pot them; separate the roots from the medium and plant them into growing soil.

III. Points to Note

When bougainvillea is propagated by cuttings, it first sprouts and grows branches before rooting, so when it sprouts, do not transplant or loosen the soil, otherwise rooting will be affected.
