For the Love of Plants STOP! Planning Your Garden Part Two

Your Murdering Your Plants…..

All of us have encountered someone in our lives whom we just couldn’t stand. For some reason they way they walk, talk, laugh, smile…. It just irritates us. They zap us of our energy. Thank goodness for friends, people who energize us and make us feel good about ourselves.

Did you know that plants, like humans, also react negatively to certain plants? Sometimes specific plants can actually kill and prevent the growth of others. Take sunflowers for example. They are beautiful, and a staple in most gardens. That beautiful sunflower… it emits a chemical which prevents the growth of most vegetables and flowers. This chemical can last in the soil and stunt the growth of other plants for years.

Shocked? I was too when I learned about the “evils” of the sunflower. Especially since sunflowers are my favorite flower and I plant them every year. Luckily plants, like humans, also have companions “best friends”. When these plants are planted together they benefit each other. That nasty sunflower. While it hurts most plants, it is good for corn, peas, beans and squash.

The second step for planning your garden (click here for step 1) is going through all of the things you intend to plant this year and find out what plants work well together, and what plants harm/kill each other.

Below is the list I have made for my own garden this year. Once you find out which plants work well together it is time to move on to step 3.

  1. Oh no! I wish I’d read this before I started planning out my potted sunflower companions. Fortunately, one of them is a squash – so we’ll see what happens!
    Do you know if some of these chemicals stick around if you clean and re-mix old potting soil?

    1. So, before I knew this, I would rotate out and plant new plants there the next year. They grew, poorly, and I always blamed the soil. We started making composting and mixing leaf matter and compost into the soil every winter and fall and everything grew much better.
      The stuff I have read says the chemicals stay in the ground a while.
      I would check out some organic gardening sites to see what they say. Last year I planted lettuce where I had planted sunflowers the year before. It grew… but not much. It got stuck at a small stage and didn’t seed in the fall.
