### How long do you leave seedlings in tray?

Seedlings should be left in the tray until they have developed enough roots and leaves to be transplanted into individual pots or into the garden. This usually takes about 4-6 weeks, but it can vary depending on the type of plant. It is important to monitor the growth of the seedlings regularly to ensure they are not becoming overcrowded or rootbound in the tray.

### How do you know when seedlings are ready to be transplanted?

You will know seedlings are ready to be transplanted when they have at least 2-4 true leaves, sturdy stems, and a healthy root system. True leaves are the leaves that come after the initial seed leaves and look more like the leaves of the mature plant. The stems should be able to support the weight of the plant, and the roots should be well-developed and starting to fill the tray.

### How should seedlings be transplanted from the tray?

To transplant seedlings from the tray, gently loosen the roots from the soil with a small tool like a pencil or chopstick. Carefully lift the seedling by the leaves, being careful not to damage the stem. Make a hole in the soil of the new pot or garden bed that is slightly larger than the root system of the seedling. Place the seedling into the hole and gently pack the soil around the roots. Water the seedling immediately after transplanting to help reduce transplant shock.

### How should seedlings be cared for after transplanting?

After transplanting, seedlings should be placed in a location with adequate sunlight and watered regularly to keep the soil moist but not waterlogged. It is important to protect the seedlings from extreme temperatures and strong winds, especially in the first few days after transplanting. Fertilize the seedlings with a diluted liquid fertilizer every 2-4 weeks to help promote healthy growth.

By following these guidelines, you can ensure that your seedlings have the best possible start and continue to thrive as they grow into mature plants.
