How to Grow Baby Plum Tomato Plants

This guide will provide step-by-step instructions with my own photos, so you can learn about growing your own tomatoes in pots and containers.

I always buy my seeds online, because they are very cheap and are of great quality too. These are the plum tomato seeds that I bought this year and, as you will see from the photos, I got a bumper tomato crop from them.

I only used a few of these seeds, so I have plenty of the same for next year too.

How to Plant Baby Plum Tomato Seeds

  1. Add some potting compost to a seed tray and flatten down with a stick.
  2. Use your finger to make grooves in a straight line all the way across the tray.
  3. Pour some of the seeds onto the palm of your hand.
  4. Using your other hand take a few at a time and place in the grooves.
  5. Cover them with more soil and press down hard so the seeds make contact with it.
  6. Water in well.
  7. Place the containers in a warm sunny room. The ideal temperature would be 70 to 80 degrees Fahrenheit.
  8. Do not allow to dry out.

How to Grow the True Leaves on Seedlings

You will see the seedlings appear in about 5 to 10 days.

When you see the seedlings appear in the tray it is time to acclimatize them outside.

  1. Place the tray outdoors in a position where it can get plenty of sunlight.
  2. Keep watered and do not allow the soil to dry out.
  3. About a week later your tomato seedlings will get their first true leaves. These will be the second set of leaves on each plant. The first leaves to appear are called cotyledons.

How to Transplant Tomato Seedlings

Once the first set of true leaves appear you will find the tray will become too small for all the seedlings to grow properly. Now is the time to transplant them into individual pots.

  1. Fill the Module tray which in my case contains 6 larger pots with compost.
  2. Make a hole in the centre of each pot.
  3. Carefully take out individual seedlings by inserting a sharp tool into the soil and lifting by the cotyledon leaves.
  4. Do not touch the stems or you could break them and kill the seedling.
  5. Drop into the hole you made.
  6. Gently fill this in with more compost and make sure that it is covered up to the first two leaves.
  7. Continue like this until you have finished transplanting all your seedlings.
  8. Water each container at the base of the small plants and leave in a bright and sunny position.

How to Transplant the Tomato Plants to Larger Containers

After about three to four weeks the plants will be ready to transplant into your garden soil or in containers.

  1. Prepare this area by filling the containers or an area in your garden with good soil.
  2. Water in well.
  3. Do not place your tomato plants too close together as they need space to grow and produce fruit.
  4. Remove each one from the Module by pushing it up from the bottom and freeing it
  5. from each pot. This protects the roots.
  6. Dig a hole where you want to place each plant.
  7. Add a small amount of water to this.
  8. Place a plant down into the hole and cover in with more soil.
  9. Press down hard to make sure the plant is secure.
  10. Continue like this until they are all finished.
  11. I put three in the larger containers and two in the smaller containers.

How to Water the Tomato Plants

Never let your plants get too dry but also do not over water them

  1. Continue to water the plants when the soil on the surface is dry to the touch.
  2. Always water at the stem and avoid wetting the leaves. If the leaves get too wet there is a chance of getting diseases that will kill all your plants.
  3. Use rain water when possible because tap water has all sorts of chemicals added.

Staking the Tomato Plants

Because they can grow tall, most of these plants need to be held up by using stakes. I use long and thin branches for my stakes. You can also use garden canes or specially made flat stakes

  1. Place whatever stakes you are using securely right into the soil next to each plant.
  2. Cut a piece of string.
  3. Gently pull the top of each stake towards each other.
  4. Tie the three pieces together at the top.
  5. This will produce a wigwam effect.
  6. Cut a few pieces of string the same length.
  7. Starting at the bottom tie the stems to each support gently.
  8. As the plants continue to grow tie them to the stakes.

How to Take Care of Them as They Grow

The tomato plants will grow quite quickly and become bushy as well as tall. Watch out for side shoots at this stage.

Gently pinch out any of these with your fingers. The reason for this is the plants will continue to produce more and more leaves. You want it to concentrate on the main foliage which will then be able to produce lots of flowers. It will take about twenty to thirty days for each plant to mature.

How to Remove the Excess Leaves

It is important once the flowers are established that you remove most of the leaves from the plants. By doing this you give the flowers a better chance of growing into tomatoes. They will be able to get lots of sun and sunlight for ripening the fruit.

  1. Go to each plant and cut off the stems of each leaf with a sharp secateurs.
  2. Be careful not to go near the ones that support the flowers.

How to Support the Flower Stems

You will see bunches of small yellow flowers. These will eventually turn into your plum tomatoes.

  1. Some of the bunches will start to droop because of the weight of the new tomatoes on them.
  2. Cut a small piece of garden string.
  3. Tie one end onto the stem of each bunch.
  4. Lift it up slightly and tie the other end to the main stem of the plants.
  5. This will give each bunch a helping hand and keep them upright so it can continue to take advantage of the sunlight.
  6. Use liquid tomato feed on all the plants once a week at this stage. This will give them more energy and produce healthier baby plum tomatoes.
Tie the bunch of tomatoes growing on the plant to a stronger stem.  This will help it stay there.

How to Harvest the Baby Plum Tomatoes

The tomatoes will all mature at different times. The general rule is once the flowers appear they will turn into ripe tomatoes around three to four weeks later.

  1. Each day go into the garden and see which of the baby plum tomatoes are red.
  2. Twist these ones with your fingers and they
  3. will come off the stem quite easily.
  4. Continue to do this every days as you need to.
