Super important topic in our region!
My kitchen garden is a terrace on a sloping shelf of rock. It seems to drain pretty well. During last year's floods it received flooding
runoff from upslope, but aside from a couple little squash plants who got washed out, everything else seemed to do ok. I don't seem to be having
serious water-logging problems although the soil is still too much clay and not
enough organic material and I think this affects some plants which prefer better drainage. I have buried
wood to retain moisture through dry periods, and it seems to be helping to even things out. I think having growing beds of different heights helps to give more plants a chance to avoid drowning, while being able to reach down to water stored in the buried wood.
This year our major focus has been on water management, especially trying to work on solving our serious flooding problems because most of the land is a drainage for hundreds of acres, and we've gotten very tired of panicking whenever it rains hard We're trying to become more resilient in the face of this challenge which is only going to become greater in this region. We want to hold more water in the soil, while letting it drain naturally to the creek and on down to the river.
