Pepper Containers

This year I planted 4 pepper-plant tubs with different soil mixes.

In this video they are compared and dug up to see what can be learned from the roots, to improve future container plantings.

Interestingly these trials have led to the conclusion to put rotted wood at the top of the container (not in the bottom), just like nature does it in the forest, with rotted logs on top of the ground.

Based on this and other root excavations, here are some ideas for future soil arrangements I plan to test next. Will try to test with lettuce over fall, but might have to wait until next spring.


  1. It was interesting to see the differences in the root-balls. Just from looking at the root-balls, I'd call number 1 as the winner. It had a nice yield, though not the best yield, which is a bit surprising.

    Have you thought of drilling aeration holes in the sides of the pots, to increase the oxygen getting to the roots? It might help decrease the sogginess of the bottom layer.

    Thanks for posting your experiments!

  2. Patricia,
    Have seen posts where someone did drill holes all over their pot. It would help, but looks ugly! Also if the soil dries out around the hole then the roots won't be able to take advantage of the extra air.

    I'm going to try a tub of just compost and then take a stick or dowel and poke a lot of holes into the mix from the top to the bottom. Similar to what they do to aerate grass. With a hole or "air column" inside the soil, it is more likely to stay wet.
