My watering can rose tends to block up and then the water flow is very uneven and slow and then drips from the lower edge. Whenever, I watch Monty Don water his seedlings his flow is perfect (
). It's not a particularly fine rose, just the bog standard one. I use water from the butt so it may have algae in it which could contribute to blocking the holes, although the water looks nice and clear and I use it regularly. Perhaps I should leave the can empty to prevent algal build up, but then I like to leave a full can in the greenhouse to acclimatise the water to the ambient temperature. Any one got any tips how to keep the rose clean?
