When it’s time to transplant a tomato plant, what size should it be? When your tomato plant has grown to be three times taller than the container it was growing in, it is typically time to transfer it into a larger one. Wait until your plant is 12 inches tall before upgrading it from a container that is 4 inches in diameter to the next larger size so that there is sufficient stem length to bury.
- Containers for starting seeds (or soil blocks)
- four-inch pots
- 1-gallon pots
- The last planting in the garden or container
When growing tomatoes in containers, the ultimate container size should be 10 gallons (for determinate kinds) or 20 gallons. This is the case whether you are growing determinate or indeterminate varieties (for indeterminate types). Plant your tomatoes at a distance of at least 18 to 24 inches apart if you are growing them in the ground (more space is always better for proper air circulation).
How Big Should tomato seedlings be before transplanting?
When the seedlings are between 3 and 4 inches tall and the overnight temperatures are regularly above 50 degrees, it is appropriate to transplant the tomatoes into the garden. Tomatoes are ready for transplantation into the garden when: You may either use a farmer’s almanac or a biodynamic calendar to time your planting according to the ideal alignment of the moon and other celestial bodies, or you can just plant them whenever you have the time.
- Create a hole in the center of your tomato bed that is at least a few inches deeper than the depth of the container the seedlings are in. This hole should be used to transplant the seedlings. Check the back of the seed packet to determine how much space should be left between the seedlings of each type you intend to plant. The distance between each plant is determined by its mature size and might be anywhere from 30 to 60 inches (avoid the temptation to plant the tiny seedlings closer together – overcrowding can contribute to the spread of diseases).
- Take each seedling out of its container and very carefully separate its roots from the soil.
- When the seedlings are planted, just the uppermost leaves should be visible above ground. This method is the kiss of death for some plants, yet it provides several benefits to tomato plants, including increased resilience to wind and drought as well as improved root development.
- After giving the seedlings their initial drink of water, firm the dirt around the plants with your hands to create a protective barrier.
When should I repot my tomato seedlings?
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.
- Cotyledons, 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.
- 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.
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. The stems can be buried to give them more strength and to stimulate the formation of new roots.
How do you keep tomato seedlings from getting leggy?
How to save tomato seedlings that are getting too tall – If you have tomato seedlings that are leggy, the best approach to correct them is to repot the seedlings (or transplant them) and bury the stems up to the lowest set of leaves. This is the most effective way to correct leggy tomato seedlings.
This will not only address any issues with legginess, but it is also a suggested procedure for strengthening tomato stems and assisting their roots in developing greater bulk. This is because the stem of a tomato plant has the potential to produce adventitious roots, which are little root-like nubs that occasionally appear to sprout in mid-air.
These adventitious roots are the very first stage in the growth of the plant’s roots. They are also known as root initials or tomato stem primordial. The adventitious roots have the potential to grow into full-fledged roots if any portion of the stem comes into touch with the soil.
- This helps to anchor the stem and further strengthens the plant’s overall root system.
- Before transferring tomato seedlings into the garden, I personally like to repot them two or three times in smaller containers first.
- At this time, you don’t need to worry about digging a very deep hole because you may easily plant your tomato in a shallow trench instead, which will save your back from strain.
You may learn more about why and how to transplant tomato seedlings by reading the following: (a Second Time) This technique of partially burying the stems of seedlings works just as well for tomatillo, eggplant, and pepper seedlings, regardless of whether or not the seedlings have lanky growth.
Is it necessary to transplant tomato seedlings?

This may appear to be an unnecessary step to some people. The process of transplanting seedlings does not take a lot of time and is quite simple to carry out.
How big should seedlings be before pricking out?
When your seedlings have at least two sets of leaves and have grown to the point where they can be handled, it is time to move them to a larger space. Pricking out will go off without a hitch when you enlist Westland’s services because they have the necessary tools and advise.
When should you replant seedlings?
1. They have one or two sets of true leaves – The best time to transplant your seedlings is around three weeks after they have sprouted or when you have one or two sets of true leaves. This is the period when they are ready to be moved. It is in everyone’s best interest to transfer them to new containers before they begin exhibiting any of the indicators of stress that are described below.
