The exposure should be progressively increased over the following week or two until the plants are in full light throughout the day (shade-loving plants are an exception they should not be exposed to day-long sun). When preparing seedlings for outside conditions, a cold frame might be helpful. Leave them there for several hours each day. Stop providing them with fertilizer and move them to an area that is protected from the wind and has filtered light. Hardening off the seedlings allows them to resist the intense sunlight and lower temperatures that are seen outside around ten days before they are ready to be planted. To assist the transplants in recovering from the stress of the relocation, keep the containers out of the direct sunshine for a few days. Immediately hydrate the plant that was transplanted. Create a hole in the planting mix of the new container, insert the seedling in the hole, and then pack the soil firmly around the seedling. When handling seedlings, be sure to do so by their leaves to prevent causing any damage to the sensitive stems. Alternately, you can lift a group of seedlings and carefully separate the individual plants by separating the tangled mass of roots.Loosen the dirt that is surrounding the seedlings with a kitchen fork or spoon (this will make it easier to remove them), and then carefully remove each seedling one at a time.When you are ready to transfer seedlings, fill each new container with a planting mix that has been moistened. To minimize the amount of root damage that will be caused to seedlings when they are transplanted into the garden, it is recommended to start seedlings in their own individual pots or in cell packs.

If you want to be able to rescue the majority of the plants that have germinated, you will need to move them to larger pots so that they can develop to a size where they can be planted outside.Thin the seedlings that are growing in individual pots or cells until there is just one plant in each container.This is an option if you do not require a large number of plants.You may thin the plants out where they are by simply pinching or snipping off the surplus seedlings, leaving the remaining seedlings spaced approximately 2 inches apart. After the seedlings have grown their second set of true leaves, it is time to either transfer them or thin them out. Instructions in step-by-step detail and useful hints are provided to assist you in ensuring the success of your young seedlings. How can you tell seedlings are ready for transplanting? The stems can be buried to give them more strength and to stimulate the formation of new roots. Tomato seedlings that are too tall for their pots should be replanted as soon as possible to prevent them from becoming even more emaciated and lanky. After a few days, after the real leaves have unfolded and begun the process of photosynthesis, the cotyledons will fall off naturally, making room for the plant to begin its transition into its adult form. When should tomato seedlings be repotted into larger containers? When tomato seedlings have reached a height of at least three inches and have their first true leaves, also known as the second and subsequent sets of leaves that develop, they are ready to be transferred into their permanent homes.Ĭotyledons, which are the first leaves to emerge from a seedling, are not true leaves at all rather, they are embryonic structures within the seed that feed sustenance to the seedling until it is able to produce its own food.
