I have very large flower pots, 10 are 33 cm square and 6 are 50 cm diameter. I have put in a sprinkler system and attached spaghetti to take the water to top of the pots. For emitters I have some that just drip and some sprayers. Problem is the square pots have standard ice berg roses in them and there's no other vegetation in the pot to spread the water around. The ones that drip have worn a tunnel in the dirt and most of the water comes straight out onto the patio. With the sprayers it's a little bit better, but a lot of the water sprays over the edge of the pots onto the patios. In summer I put a few seedlings around the trunk of the roses. This helps spread the water around to some extent, but they often die because they don't get enough water. Increasing the volume of water just makes more water come out of the pot onto the patio. Any suggestions as to what I can do? I've put stones in the bottom of the pots and old rags to try and stop the dirt being washed out but this doesn't stop it. Has anyone got some ideas what I can do to improve things?
