Guava Propagation Techniques: Key Points and Methods Explained

Guava, also known as ba-la, is a tropical fruit that is deeply loved by consumers on the market. To grow it, you first need to understand its propagation methods. Guava can be propagated by seed, cuttings, layering and grafting. Let's take a look at the detailed introduction below.

1. Seed propagation

First, select fully ripe fruit from a mother plant with excellent variety and high yield. After harvesting the fruit, let it ferment, then wash the seeds clean, remove the empty grains, and dry them before sowing. However, its seed coat is hard and absorbs water poorly, so before sowing the seeds must be soaked to promote germination. Sow only when the embryo buds are exposed; this way, germination is not only uniform but also has a high germination rate. Using the direct seeding method, evenly scatter the seeds on the seedbed, then cover with a layer of soil, cover with grass and water thoroughly. Then water 1-2 times a day depending on the weather. They will germinate in about 30-40 days. When the seedlings grow 2-3 pairs of true leaves, they can be transplanted. After transplanting, strengthen fertilizer and water management. When the seedlings grow to more than 40 cm, they can be planted out or grafted.

2. Cutting propagation

First, select healthy, pest- and disease-free, semi-lignified branches from a 1-2 year old mother plant as cuttings. Cut them into 15 cm sections, whittle the base into a triangular prism shape, and keep 2-3 pairs of leaves at the top. Dip the lower end of the cutting into rooting hormone for 3-5 seconds, then use a rod-like object of the same thickness as the cutting to make holes in the seedbed at a certain row spacing, requiring a hole depth of 3-5 cm. Then insert the treated cuttings into the holes, press with your hands so they fit tightly, and water thoroughly. After the roots have formed, water frequently to keep soil moisture above 85%, and adjust the light at the same time to avoid direct sunlight. After one year of cultivation, they can be transplanted.

3. Layering propagation

On a high-yielding, high-quality mother plant, select branches that have grown for 2-3 years, then perform ring-barking at about 50 cm from the top shoot, with a width of about 2-3 cm. Apply rooting hormone, then wrap it with straw and soil. After about two months, dense new roots will grow at the ring-barked area. At this point, the branch can be separated from the mother plant and temporarily planted. When temporarily planting, most of the branches and leaves need to be cut off, leaving only a small portion, so as to prevent new buds from sprouting too quickly and the roots being unable to meet their nutritional needs. After temporary planting, appropriate shading is needed, and water should be regulated, watering 1-2 times a day. After half a month, control the watering amount to once every 2-3 days. After one month, apply diluted fertilizer water as a top dressing to make the seedlings grow robustly.
