When I write about gardening, I
report on what I have done that works or doesn't work for me. This
does not imply that I know all the answers. It is hard to know all
the answers when I have only scraped the bucket in figuring out what
the questions are..
I am writing to pass on what I am doing. Is this what everyone else
should be doing? By no means. I am a firm believer that we can learn
from the past and improve on this. The wheel has already been
invented and maybe others can use some of what I do or adapt it to
their needs.
I am not afraid to try something only learning that that was not a
great idea after all.
Last fall was such a situation. I am trying minimum tillage for many
reasons and I am in the experimenting stage to see what works .
Established cover crops were burned down with the use of greenhouse
film. The days were warm / sunny and this worked well. Dead
material was left as a mulch and planted through. This worked fine
for taller transplants but seedlings were destroyed by flee beetles.
There also was a “miller” moth flush last fall. These moths are
the parents of cutworms.
There were a few things that I should have done but did not.
Leaving the film on too long would warm soil too much for fall
plants. Sooo I took the film off. I did not immediately cover with
fabric. Once removed, the flee beetles and moths came in to this nice
habitat I had created for them, and reproduced to no end. This
really effected my seedling survival rate.
It can be said that hind sight is 20 /20.
First after removing the cover I should have: A, tilled under the
debris (I would have had to have a decomposing period to do this);
B, raked this debris off to compost; or C, have immediately covered
with fabric to stop both of these insect's access.
Of these alternatives noted above, the tilling would be a non starter
because there would be a 2 week delay for decomposition.
Raking off and covering should solve this problem or covering until I
could rake the debris off.
By growing a cover crop, New Zealand clover for an example, a fair
amount of bio mas can be produced in the soil from its roots. If the
clover was allowed to begin to bloom then there would be the added
benefit of nitrogen added to the soil.
Any cover crop that was burnt back and raked off would add to the
soil. There is as much growth above ground as there is below the
ground. Roots just decompose a lot quicker. It is the lignin in
woody material that slows its decomposition and helps build soil
humus.
It is my intent to mulch the beds with a compost that is high in
lignin slowly working its way into the soil.
