When To Transplant Seedlings From Seed Tray
When Seedlings Should Be Transplanted to Prevent Disease and Grow Healthy Plants When the seedlings have produced their second set of true leaves, it is time to thin or move them. If you do not need many plants, you may thin them in place by pinching or snipping off the extra seedlings, leaving the remaining seedlings apart by approximately 2 inches.

  1. Individual seedlings in pots or cells should be trimmed to one per container or cell.
  2. If you wish to keep the majority of the newly germinated seedlings, you will need to transfer them into bigger pots for growth to planting-out size.
  3. For this purpose, it is advisable to use individual pots or cell-packs so that seedlings will not experience excessive root disruption when they are placed in the garden.

To transfer seedlings, use wet planting mix in each new container. Loosen the dirt surrounding the seedlings with a kitchen fork or spoon, and then carefully remove them one by one. Or, lift a cluster of seedlings and carefully separate the individual plants by separating the tangled mass of roots.

  1. Handle seedlings by their leaves to prevent harming their delicate stems.
  2. Create a hole in the planting mix of the new container, insert the seedling in the hole, and compact the soil.
  3. Irrigate the transplant immediately.
  4. To allow the transplants to recover from the relocation, shield the containers from direct sunlight for several days.

About ten days before the seedlings are ready to be planted outside, they should be hardened off so they can endure direct sunlight and lower temperatures. Stop fertilizing them and place them in a wind-sheltered, filtered-light area outside for several hours daily.

How long may seedlings remain in their trays?

1. They have one or two sets of true leaves – The optimal time to transplant seedlings is around three weeks following germination, or when they have one or two sets of true leaves. It is preferable to place them in new containers before they exhibit the following indications of stress.

Why Do Young Plants Grow Tall? – Lack of light is the primary cause of spindly seedlings. In gloomy settings, as the seedlings grow, they push upward in quest of direct sunshine, a never-ending endeavor. The stems will keep growing taller and longer at the expense of bushy leaf development.

This impact is exacerbated when nighttime temperatures are excessive, such as when seedlings are cultivated inside. A mix of warmth and darkness causes the seedling to “believe” that it is still attempting to break through the soil’s surface, so it expends more energy on vertical development. Overcrowding of seedlings is a second source of legginess that is nevertheless significant.

As neighbors come closer, they attempt to outcompete one another for sunshine by growing taller and taller in a race that none can win.

When you make a purchase via one of our site’s links, we may receive a commission. It can be unpleasant. You cultivate your plant from seed with effort. Now that it has been transplanted to the garden, it is experiencing transfer shock. Depending on the plant or tree being grown, transplant shock might endure between two weeks and five years.

  • This might cause a temporary halt in the growth of flowers and fruits.
  • The longer the transplant shock persists, the greater the likelihood that the plant will perish.

If you have placed many seeds in a seed tray, it is essential to prick out the seedlings and transplant them so that they have sufficient area to grow and may benefit from the additional nutrients in the fresh compost. Once flower and vegetable seedlings develop their first pair of real leaves — the first set of leaves that resemble the parent plant – prick them out.

  1. Use a pencil or dibber to pry the seedling’s roots from the compost, while holding the seedling by its leaves, as they are replaceable, and never by its stem, which is easily crushed.
  2. Small pots or trays with peat-free, all-purpose compost should be used to plant seedlings.
  3. Use a pencil or dibber to create a hole in the compost, and then drop or spiral the seedling into the hole so that the surface of the compost is almost even with the lowest leaves.

Planting a seedling deeply will aid in securing its position. Firm the compost around the seedling gently. Aim to transfer 12 seedlings into a half-sized seed tray. Use a dibber to define the spacing, with three plants across the width of the tray and four plants along the length.

  1. It is preferable to transfer huge seedlings into separate containers.
  2. Once your seedlings have been transplanted, water them thoroughly with a watering can equipped with a fine rose attachment and set them on a windowsill, in a greenhouse, or in a propagator.
  3. If seedlings are not pricked out, they may succumb to a disease known as, causing them to collapse.

By sowing seeds individually in modular trays, it is feasible to prevent pricking out seedlings, but these trays require more room in propagators and on windowsills. Prick out seedlings of flowers and vegetables after they get their first pair of real leaves.

When should the greenhouse cover be removed?

When should I remove the greenhouse cover from my seed starter? – The greenhouse cover retains moisture, which increases the relative humidity for rapid germination. Remove the cover as soon as the first small sprout appears. This permits air to circulate around the seedlings, reducing the likelihood of illness. Keep lighting 4 to 6 inches above seedlings.
