Superprize tomatoes update: Polyethylene box vs plastic pot

Although the amount of potting mix in the 250 mm pot, and the polyethylene box are probably about the same, however, the plant in the pot is showing much better and faster growth. Both of them are showing their first flower pinnacles, but the pot grown plant is a stronger plant.

Since the plants were small when they were planted, I didn’t fill the pot with potting mix all the way up, so I can add more mix in as the plant grows. Tomatoes being a relative of potatoes, they grow roots where their stem touches the soil too, and by doing it this way, the plant anchors better into the ground and have more roots to take in water and nutrients. I couldn’t do that with the polyethylene box because it was shallow.

The other two plants in smaller containers are doing just a little bit better than the polyethylene box, which was a surprise since the amount of mix/soil in the box was at least double.

My conclusion is tomato plants do better in taller rather than wider containers of similar volumes, therefore, when transplanting tomato seedlings from their punnets, plant them into tall, minimum 250 mm containers. Fill half the container with potting soil/mix, bury up to their top two leaves, and add more potting soil as they grow until the pot is 85% full. My problem is, I don’t have any more 250 mm + containers!! Need to go out and buy some more!

Comparison

Lastly, I think the wider containers like the polyethylene boxes are probably better for vines… Maybe I should transplant the tomato in the box to a pot, and plant pumpkins or watermelons in the box instead ~

  1. I’ve had good success with deep planting too. Can definitely see the difference it makes in your photos. Enjoy your tasty tomatoes – they’re not too far off now by the looks
