Another cat out of the bag.
Last year I let the cat out of the bag telling of how cat litter (not the wood, paper or clumping types) is an excellent planting medium - even better than potting compost because it retains moisture whilst allowing lots of air to the roots therefore allowing vigarous growth. Pluss it's difficult to overwater because what the plant doesn't need flows out of the bottom of the pot. I use low dust 'Supercat pink' cat litter.
Cat out of the bag 2. This dust mixed with water makes an excellent spray insecticide against aphids, scale insects and caterpillars. It works by leaving micro particles of dust on the plant. These dust particles are razor sharp and will cut through the insects carapace (skin/shell). The dust itself is inert and doesn't harm the plants. On food plants just wash as normal before eating.
I hope this helps anyone who doesn't want to spray with chemicals.
Whilst not a question its useful infomation and something to read.
Many thanks to bonsai4me.com
