Every year we have a bumper crop of burrowing garden destroyers.
Experimented with five gallon buckets last couple of years to thwart the little buggers. Five holes in the bottom with a spade bit. Old busted mortar and bricks in the bottom. Broken up sticks on top of the bricks. Soil needs to provide drainage but needs to have some elements to hold moisture as well.
Some buckets I buried in the ground like for squash and melons that I didn't want to have hanging way over the side to reach the ground. They did real good. Had several above ground buckets with tomatoes and they loved it too, especially once their roots went down through the holes. Peppers would have liked the buckets more if I'd paid more attention to soil prep; it was way too clay packed. My booboo.
This year most of the buckets will be above ground with tomatoes and green and orange varieties of eggplant.
Half the in-ground buckets were pulled up today. I'm doing the squashes, climbing beans and Armenian cucumbers in raised beds with trellises made from remesh (going vertical).
Lessons learned.
A sprinkler is a waste of time.
Positioning buckets in a group (spaced apart from each other) can still result in closed off access when plants get spread out. Once the roots go down through the holes it's best to not move the buckets. Positioning in a row works better.
To be sure the plants get plenty of water, the distance from the top of the dirt to the rim of the bucket needs to big enough so that it can serve as the fill zone for the water. In other words, to hose that volume full of water and it's good.
Sluicing the volume with fertilizer infused water is a good technique for fertilizing because the surface area of the soil is relatively small and inconvenient to work.
With that decreased volume of soil in a bucket, the soil quality becomes even more important.
This year most of the bucket planters will be above ground with tomatoes and green and orange varieties of eggplant.
Oh, and the upper parts of some rectangular buckets (recycling some sodium hydroxide containers from Scandinavia
) are getting a hammered metal look spray paint for partially buried planters in the wife's flower garden.
