Slow water
Plants like water. But watering plants needs to be done in the correct way. If you give a plant water each day, the roots will not grow deep into the ground and the plant will become 'lazy': this way it will suffer a lot from a short period without rain.
The best way is to give the plant a lot of water, so this sink deep into the ground: now the plant will grow deep roots, making it stronger.
The best way to give water, is to give the plant a lot of water, let this sink in and then give some more water.
For plants having a small access point to water, this makes it difficult, since the small area can only take up the water slowly.
So you should be able to give the plant a small stream of water, but for an extended period. And here is the solution.
'Slow water' allows you to screw a bottle on top and this will then deliver the water in a small stream until the bottle is empty.
