This weekend we pulled up all the old plants and put them in the compost bin. We hoe'd down the built up rows that the plants were growing in so the soil was kinda level. Over this we spread out all the finished (and not quite so finished) compost we had. I spread out the rest of an old hay bale we had left over from mulching in the spring and covered this with with 3"-5" of the grass clipping and dropped leaves I bagged up with the mower. When the rest of the leaves fall,I'll mow/shread/bag themand dump them on top,too. The 6' canna lillies will be cut down and laid on to to keep them in place.
In the spring,we will simply pick out the canna stalks, rake the mulch out of our planting rows, turn in some compost down each row with a pitch fork and plant! Most of what was put down today will be gone by next May and we will need more mulch between the rows. No tilling needed!
