|---|---|
| 6-8 inches | Leaf lettuce |
| 10-12 inches | Romaine lettuce |
By carefully thinning lettuce seedlings and providing adequate spacing, you’ll ensure optimal growth and a healthy crop of delicious lettuce.
Watering And Feeding Lettuce Seedlings Indoors
Proper watering techniques are essential for the healthy growth of indoor lettuce seedlings. When watering lettuce, it is important to strike a balance. Overwatering can lead to root rot, while underwatering can cause the plants to wilt and eventually die. The best approach is to keep the soil consistently moist, but not waterlogged.
One way to achieve this is through bottom watering. Place the seed tray or pot in a shallow tray filled with water and allow the soil to soak up the moisture from the bottom. This prevents waterlogging and ensures that the roots receive adequate hydration.
Another method is to water from the top using a gentle stream of water. Aim to wet the soil evenly without disturbing the delicate seedlings. It is recommended to use a spray bottle or a watering can with a fine rose to control the flow of water.
In addition to watering, providing the necessary nutrients is crucial for the healthy growth of lettuce seedlings. A balanced fertilizer high in nitrogen can be applied once the seedlings have developed their first true leaves. This will promote vigorous growth and leaf production.
| Watering Tips | Fertilizing Tips |
|---|---|
| Keep soil consistently moist | Use a balanced fertilizer high in nitrogen |
| Avoid waterlogging | Apply fertilizer after the first true leaves appear |
| Bottom watering is recommended | Promote vigorous growth and leaf production |
| Water gently with a spray bottle or fine rose |
