Growing green lettuce at home
Green lettuce is a rewarding, fast-growing plant. It can be grown in the garden, on a balcony or indoors all year round. Indoors it does best with 12–14 hours of light a day, and the optimal temperature is between 15 and 22 °C.
Smart gardens and planters such as SIMPLY and AURELIA give you constant access to fresh leaves – with no need for daily watering or fussing with growing medium.
Planting green lettuce from seed
- Sow the seeds shallowly in a light growing medium or use smart soil with seeds.
- Keep the medium moist until seedlings emerge (7–14 days).
- Once sprouted, provide plenty of light for firm, healthy growth.
- Lettuce likes lower temperatures and regular leaf picking.

How to harvest green lettuce so it keeps growing
- Pick the outer leaves regularly and leave the inner ones to keep growing.
- Do not pull up the whole plant – that way you ensure a constant supply of fresh leaves.
- It is best to harvest in the morning, when the water and nutrient content is highest.
Common problems and solutions
| Problem | Possible cause | Solution |
| Bitter leaves | Too much heat | Grow during the cooler part of the day or indoors |
| Yellow leaves | Too few nutrients or too little light | Add nutrients, provide more light |
| Weak growth | Overcrowded planting | Thin out the plants |
| Pests | Slugs, aphids | Remove by hand, use natural methods |
| Wilting | Lack of water | Water regularly or use smart soil |
The difference between green lettuce and other varieties
- Green lettuce (Lactuca sativa var. Lento): mild flavour, crisp texture, fast growth.
- Crisphead lettuce (Iceberg): firmer, crunchier, keeps longer after harvest.
- Red lettuce (Red Salad Bowl): rich in anthocyanins, with a stronger flavour.
How to store green lettuce
- In the fridge: keep it in a perforated bag or a container with a lid.
- Washed and dried: keep it in tea towels or paper towels so it stays fresh longer.
- Do not freeze: it loses its texture and turns mushy.
