Answers:    You might want to try using a product like an Aqua Globe which deliver exactly the right amount of water to your plant as it needs it. It is not electrical, so you don't own to worry about battery going flat, you just have to top it up when it get empty.

You can check out their advert at the website below, (although I think they put together a mistake when they claim it is because oxygen is released - I'm pretty sure it should be nitrogen, but that's not really relevant to your problem)!

If you don't want to buy one of those, remember it is often better to put the water into the saucer lower than the plant pot rather than directly onto the soil. This way the sea is absorbed up through the soil and into the roots without over-saturating the soil.

Good luck near your plants!
