Up until recently the fronds used to get broken up and put into the compost or we would wait until there was a bulk garbage colection and put them out for that.
But now that I am now longer throwing garden waste into the bin (gulp) I have found a use for them.They are the retaining sides to my no dig garden beds. As more fronds fall down I raise the sides. I am working on my third no dig garden now. All green waste like fern fronds, grass clippings and other prunings gets thrown into the bed.
Speaking of the beds, the no dig garden beds are going wonderfully. The first one I made is growing pumpkins and there are a few pumpkins growing nicely. The vines have gone crazy and are rambling everywhere.The second no dig garden has watermelon growing. In the photo above you can see the pumpkins at the back and a watermelon plant towards the right bottom of the photo. There are more plants there no since this photo was taken. No watermelons yet but the plants are growing nicely.
The no dig beds are on the other side of the fence (not our land but a council walkway/reserve). There is no water supply other than rain but every couple of days I have been taking a bucket or two around the side and watering them. Mainly though they are going well with the little rainfall we have had.
I am so pleased with this reclaimed area being put to good use. And I am dreaming of all the pumpkins and watermelons.
