- Mar 9, 2008That is also a problem I face along with the soil critters. Most of my best
possible garden sites are problematic with respect to tree roots and
structures. The ECHO shallow bed system, plastic barrier covered with a
little mulch and debris and fertilized with 10-10-10 seems to work pretty
good - just started one for taro. My best systems to date are basically
container gardens made from 8 inch deep cement tubs raised to waist level on
landscpe timbers and blocks. "Soil" for them is well-rotted compost and
perlite with cypress sawdust initially fertilized with ozmocote and top
dressed with 10-10-10 as needed later in the growing season. For deep
rooted crops, like daikon radish and tomatoes, I put down a sheet of black
plastic then a 4 foot diameter hoop of 3 foot tall, 2x4 welded wire mesh and
line it with landscape fabric. That becomes a 2 cubic yard compost pile for
about half a year or less then I plant veggies in it as an elevated planter.
After a year or longer I use the compost from the hoop planters (well rotted
muck by now) as the source of the compost for the cemenct tub gardens and
also around my fruit trees and a few things that are happy in the tree roots
like ginger. All the systems are drip irrigated and the runoff waters and
fertilizes the fruit trees and things like bananas planted on the north side
of the hoop planters. I don't use a recycling nutrient solution but I do
try to make sure it is used at least twice to make sure all the nutrients
are used up.
Some day I will probably get one of those barrelponics systems going. I
once had a lot of home-made conventional flood and drain hydroponic systems
but the nutrient solution costs and electricity costs made the veggies
rather expensive. Then a couple of power outages did in the crops one year.
So, if I do any nutrient solution system now I think I'd use the one that
gets the nutrients from fish pond effluent and the electricty from solar
powered pumps. But the gadget cost on some of that high and my compost bin
and tubs gardens are doing real well so I'm not in a hurry to add any more
complexity just now. But gadgets are fun to play with ! (I'm a retired
engineer and unrepentent gadget geek).
