Incompatible Plants

Post  mrseltzer on 5/28/2012, 10:17 pm

Hi-

I have been Sq. Ft. gardening for a couple of years now. I have a lot of root systems from previous plantings. My question is, are there plants that are incompatible; meaning that a second planting may keep the new plants from thriving?

Also, if the soil is dense with roots, will that keep new plants from being fruitful? Should I replace the soil?

Thanks for any information and opinions.

I would get in there with a fork and stir it up, pull out heavy dead root systems and toss those in the compost pile. No need to replace your mix, just add a good deal of compost.

I try to move the variety of plants from year to year. So the same crop doesn't go in the same bed repeatedly. Some plants are more susceptible to carrying over disease from year to year, like tomatoes, cabbage family, etc...

I do not think your biggest problem is incompatible roots but like camprn said they do take up a lot of room that would best be replaced by compost. So, +1 Very Happy

the only roots i'd be concerned about are those from the sunflower family, as some types exude a toxin that tends to inhibit growth of other plants. this is a protective mechanism, it helps it claim more ground for support.

@rowema........I didn't know that, and yet my books tell me that sweet corn does better growing when there are sunflowers nearby so I planted a row near my corn beds.

they are not incompatible with all plants, in fact it is said that cucumbers are sweeter if grown with sunflower. i know the hulls of the seeds can create a problem, so i try to harvest the flower heads before they drop seeds.

You're right about sunflower seeds making soil impossible to grow things. Saw it on a video. Barbara Damrosch, well known gardener and author, couldn't get anything to grow beneath her bird feeders where she fed sunflower seeds exclusively. I forget what they called the condition, but nothing much can exist where sunflower seeds drop. I forgot about that.

we planted sunflowers last year and this year.....

last year we planted a couple large sunflowers in our son's self watering container that is filled with MM.....i remember that his carrots and cucumber didnt do that well.....his sugar snap peas did great.....

this year in his container he has sugar snap peas, carrots, green onions and a tomato.....so far everything is growing great!.....if i remember this thread towards the end of the summer i will try and keep ya updated to see how all of his plants turn out.....

so far his carrots have out done all of the other carrots we have planted this year.....but.....we have learned the hard way....just because they are lush and green doesnt mean any root is growing Razz

we also had sunflowers in one of our SFG beds last year and so far everything in that bed is growing fine....only the spinach and some of the lettuce has bolted because of the heat.......

we have sunflowers this year growing up with our berry patch, flower pots and in with a crookneck squash......we shall see......we love sunflowers.....and all the ones we are growing this year came from saved seeds from last year....so far 100% germ rate.....Very Happy

hugs

I don't think its the sunflowers themselves, but the seeds that fall on the ground making it unsavory for other plants to grow.
