Each year, at the beginning of the garden season, my husband tills in a couple bags of Nutri-Mulch into the raised bed gardens. It helps refill the boxes and gives the plants an extra boost. The broccoli, cabbage, and onion plants are thriving there. Thankfully, the birds have left those plants alone.
Instead of planting annual flowers along the back of the house in between my perennials, I've planted some tomato plants, green pepper plants, Anaheim pepper plants, onions, and carrots this year. It's like traditional gardening because the seeds and plants are put directly into the ground. (I did mix a little Nutri-Mulch into the soil to help condition it before I did the planting.)
This year we decided to add a Square Foot Garden to our backyard. Opting to leave our automatic sprinkling system in place - which comes out about 15" from the fence - my handy husband was able to fit a 1' x 46' Square Foot Garden between the back fence and the sprinkler heads. Other bonuses, this spot has full sun all day and an optional trellis (the fence).
I'm going to be keeping watch to see whether the onions do better in the raised bed garden, traditional garden, or Square Foot Garden. I've got them planted in all three this year. Yeah, we like onions. :)
