How to Plant Grapefruit Seeds So They Sprout Easily

Summary: Wash the seeds peeled from a grapefruit you have eaten with clean water, then soak them, and then put them into a prepared flower pot. Before putting the seeds into the flower pot, the potting soil inside should be watered thoroughly first, and the pointed end of the seed should face up. Be careful to keep the soil moist. After passing through a winter dormancy period, the grapefruit will sprout in April of the following year.

Grapefruit can be sown directly using the seeds left over from eating, but grapefruit seeds need a certain period of low temperature to complete dormancy. Only seeds that have completed their natural dormant state can sprout.

Grapefruit Seed Planting Method

Grapefruit seeds can be stored in sand at low temperature around November to help the seeds complete natural dormancy. If around October to December, when eating grapefruit, there are leftover seeds, they can also be sown directly in a flower pot at a depth of about 5cm. After sowing, water thoroughly and place in a place with air circulation. After passing through a winter, the seeds complete natural dormancy. Water once every 7 days, and after freezing, water once about every 30 days. Wait until mid-March, then change back to watering once every 7 days. Wait until April, and the grapefruit will grow seedlings. After sprouting, strengthen cultivation and management, and by the second spring, it can be transplanted.

Grapefruit Fertilization Method

1. Soil fertilization

After grapefruit is transplanted, soil fertilization should be carried out so that the grapefruit tree can grow healthily. When young, fertilization can be done by the ring or dish method. For grown trees, fertilization is done by the strip trench, hole application, and whole-orchard fertilization methods.

2. Foliar topdressing

Besides soil fertilization, grapefruit can also use the leaf spray fertilization method. Foliar topdressing is mainly absorbed through stomata. The amount of fertilizer used is small, and the effect is also very good, but it cannot completely replace soil fertilization. Spraying fertilizer can be done in all four seasons, mainly sprayed on the back of the leaves. Under high summer temperatures, foliar topdressing should be done around 10 a.m. after the dew has dried or after 4 p.m., when the temperature is around 24°C, which is most suitable.

The concentration of fertilizer is generally: urea should be controlled at around 0.5%, clear urine at 5%, superphosphate extract at around 1%, monopotassium phosphate at around 0.4%, potassium sulfate 0.3% plus 0.2% slaked lime, zinc sulfate 0.2% plus 0.1 slaked lime, manganese sulfate 0.1% plus 0.1% slaked lime, ferric citrate at around 0.2%. Fertilizer mixed according to this ratio will make the soil very fertile and suitable for the growth of fruit trees.
