Once you notice compost coming to the top it is time to start a new Sak. The ideal use of the Compost Sak is to have two going at the same time. When the first Compost Sak starts to look full, stop adding anything to it, and start filling the second Sak. Everything in the first Sak will quickly be compost. It will be heavy so donít try to move it. Shovel it into a wheel barrel or move what you need with a bucket. You may be able to roll the Compost Sak to your garden area. Keep in mind that a Compost Sak filled with Compost will be very heavy.
To start your second Compost Sak, you may want to peel off the top layer of fill from the first Compost Sak. This will leave only compost, which you could use immediately.
After dumping the compost from the Compost Sak, re-use the Compost Sak. The product is guaranteed for one year, but you should get many years of use from the Compost Sak.
