Many plants can only be grown from seedlings. Pricking out during cultivation isn't always advisable. It can cause the plantings to die. For this reason, some crops are sown directly into separate containers of the required volume.
Why are plants planted?
Pricking out is the process of transplanting seedlings from a shared container into individual containers, or from smaller individual containers into larger ones. This procedure is essential for growing healthy seedlings. After transplanting, the feeding area increases, and the root system is able to grow and develop more actively.
If plants sown in a common container aren't transplanted promptly, they will begin to stretch, become severely weakened, and may even die. Crowded plantings develop very poorly. The seedlings lack light and nutrients. Even if they are subsequently transplanted, delaying transplantation will still negatively impact growth and fruiting.
But transplanting also has its drawbacks. The process of transferring plants to other containers can damage the root system or the above-ground part. This can cause the plants to become diseased and possibly die. Even without damage, transplanting is stressful for seedlings. Growing them without transplanting has many advantages:
- saving effort and money (no need to purchase additional containers);
- no stress;
- good development of the central root.
When deciding on a cultivation method, it's important to consider the developmental characteristics of different plants and their growing seasons. Tomatoes and peppers have long development periods, making them difficult to grow without transplanting. If you sow seeds directly into individual containers, additional lighting is required, as sowing occurs in late February or early March. Not all gardeners have the space to place a large number of containers on a windowsill and install lamps.
Which plants don't tolerate transplanting?
Some crops are very sensitive to transplanting. They don't handle stress well. Even slight root damage or changes in growing conditions can cause them to become diseased and temporarily stop growing. It's best not to transplant these plants, but to sow them directly into individual containers. These include:
- cucumbers;
- pumpkin;
- zucchini;
- mallow;
- columbine (aquilegia);
- melon;
- garden strawberry.
Strawberry, mallow, and columbine seedlings are weak, so it's best to leave them alone. Cucumber, pumpkin, and zucchini seedlings are quite strong, but their root systems are weakened. If even a small clump of soil breaks off from the roots, the plant begins to suffer. It's difficult to avoid exposing the roots during transplanting. To avoid this, seeds need to be planted widely apart. In this case, transplanting is unnecessary. Seedlings may have ample space in a shared container.
To grow strong plants, plant the seeds in cups filled with soil about 1/3 full. Peat cups are a good alternative. When transplanting to the ground, you can place the seedlings in prepared holes directly in these cups. If the seedlings outgrow their size but for some reason can't be planted in the ground yet, you can carefully cut the peat pots and then transplant them into larger containers.
Cucumber, pumpkin, and zucchini seedlings can be grown using peat pellets. The pellets can be planted in separate containers before the first true leaves appear. Before planting, thoroughly water the seedlings and prepared soil.
Caring for seedlings grown without transplanting is not much different from regular care. This includes timely watering, loosening the soil, and fertilizing. Seedlings are transplanted into open ground when the soil warms to 10-15 degrees Celsius. The plants should have several true leaves. Some crops can be transplanted, but it's not recommended. Cabbage, basil, eggplant, and marigolds may become diseased after transplanting. It's best to sow these plants directly, spacing them well apart, and then transplant them into a greenhouse or garden beds.
Not all plants tolerate transplanting well. Some crops are recommended to be sown directly into individual containers to avoid damaging the roots. Careful handling of seedlings ensures an excellent harvest.
