To successfully grow shiso from seed, it is best to plant them in the spring after the last frost. This ensures that the plants will have a longer growing season and will be less susceptible to cold temperatures.
When sowing the shiso seeds, it is recommended to plant 1-2 seeds per inch in rows that are 18 inches apart. This spacing allows the plants to have enough room to grow and ensures that they do not overcrowd each other.
One important thing to note is that shiso seeds require light for germination. Therefore, when planting the seeds, they should only be sown shallowly or lightly covered with soil. This will ensure that the seeds receive enough light to successfully germinate.
After planting the seeds, it is possible to grow shiso somewhat thickly, meaning that the plants can be grown closer together. However, if you prefer larger and more robust plants, it is recommended to thin them out to about 6-12 inches apart. This gives each plant ample space to grow and develop.
Shiso plants thrive in sunny locations, so it is important to choose a spot in your garden that receives full sun. This will provide the plants with the necessary light and warmth they need to grow and thrive.
In terms of caring for shiso plants, they require regular watering to keep the soil consistently moist. However, it is important to avoid overwatering, as this can lead to root rot. As with most plants, it is always beneficial to water them at the base, rather than getting the leaves wet, to prevent any fungal diseases.
Shiso plants are relatively low maintenance and do not require much fertilization. However, if you want to give them an extra boost, you can apply a balanced fertilizer during the growing season. This will provide the plants with essential nutrients to support healthy growth.
It is also worth mentioning that shiso plants are known to attract beneficial insects such as bees and butterflies. This can help promote pollination in your garden and contribute to a healthy ecosystem.
In terms of harvesting shiso, it is best to wait until the plants have reached a height of about 6-8 inches before starting to harvest the leaves. This ensures that the plants have enough time to establish themselves and produce a bountiful harvest.
To harvest shiso leaves, simply snip them off at the base of the stem using a pair of clean scissors or pruning shears. You can harvest the leaves as needed throughout the growing season, and the plants will continue to produce new leaves.
Growing shiso from seed is a relatively straightforward process. By following these guidelines and providing the plants with adequate sunlight, water, and spacing, you can enjoy a bountiful harvest of fresh shiso leaves throughout the growing season.
