Growing Information:
Light Requirements:
Red Shiso prefers full sun to partial shade, with at least 4-6 hours of direct sunlight per day. It thrives in warm conditions and is ideal for summer gardens. In warmer climates, it can tolerate some afternoon shade, especially during the hottest part of the day.
Soil Preferences:
This herb prefers well-drained, fertile soil that is rich in organic matter. Red Shiso thrives in slightly acidic to neutral soil (pH 6.0-7.0) but can adapt to a range of soil types as long as they drain well. Adding compost to the soil can help improve texture and fertility.
Planting Tips:
Sow Red Shiso seeds indoors about 6-8 weeks before the last frost date or directly outdoors after the risk of frost has passed. Seeds should be lightly pressed into the soil, as they require light to germinate. The soil should be kept consistently moist but not waterlogged until germination occurs, which usually takes 7-14 days. If starting indoors, transplant seedlings into the garden once they are strong enough and the outdoor temperatures consistently stay warm.
Watering Needs:
Red Shiso prefers regular watering, particularly during dry spells. It does best in evenly moist soil, so be sure to keep the soil hydrated, especially during germination and early growth stages. However, it’s important not to overwater, as excess moisture can lead to root rot. Water at the base of the plant to keep the foliage dry and avoid fungal diseases.
