Yes.

The olive fruits left as seeds must be allowed to fully develop and mature. When the shell of the seed core turns pale to charcoal color, it is harvested from late October to November. Mix the fresh olive fruit and salt at a ratio of 10:1 by weight and pour it into the jar. Step on it with your feet until the flesh and core are separated. Then soak it in clean water for 7-8 hours. Finally, use a wooden hammer to gently tap the grains to separate the pulp and core. separation.

Olive seeds need to be stratified to complete the post-ripening stage. Choose a cool and sheltered room and layer them with clean river sand. The humidity can be held in the hand to form a ball without water dripping out, and it can disperse after being released. It is better to form into small pieces. The ratio of seeds to river sand is 1:3, with one layer of river sand and one layer of seeds, so that 4-5 layers are stacked alternately. Pay attention to inspection during lamination, control temperature and humidity, and prevent mildew and overdrying.

Sow seeds in February-March of the following year. Soak the seeds in warm water for 5-6 hours before sowing, which will facilitate neat germination and facilitate management such as fertilization, pesticide spraying, and water spraying. For grafting and propagation in the original garden seedbed, the spacing between rows is about 12 cm × 15 cm. If the soil is too wide, the soil utilization rate will be low and weeds will grow vigorously; if it is too narrow, it will be inconvenient for grafting. At the same time, the seedlings will become extremely leggy, which is not conducive to strong seedlings.

For selling seedlings or transplanting seedlings, they can be sown densely. After evenly spreading 300-400 seeds/m2, use a wooden board to press the seeds into the soil, cover with 2-3 cm of fine soil, and cover with straw to keep warm and moisturize.

Extended information

Some varieties of olive trees have strong cold resistance. For example, short-term low temperatures of -8~-10℃ will not cause damage to the tree, but they cannot last long. Once frozen, it thaws very slowly and cannot enter the growth phase quickly, causing frost damage. Staying at temperatures close to zero for at least dozens of hours is conducive to the differentiation of its flower buds, thus laying the foundation for a bumper harvest.

Olea europaea has no special requirements for the soil in which it grows. As long as the pH value is between 6.5-8.0, the soil is loose and breathable, and it can grow in either siliceous soil or calcareous soil. But research shows that the best olive oil comes from the fruit of olive trees that are rich in calcium and have fertile soil.
