Flower pot tubes?

i bought a yucca plant a while back. i also bought a nice white plastic flower pot to go with it. with the pot came a long white tube and a slightly shorter red tube. the yucca lives in my front room.





my yucca plant is dying!! dont know what it needs. then one day at work, i noticed the flower pots there have a long green tube with a cap sticking out of the soil. so now im thinking maybe im supposed to use those tubes that came with my flower pot but i dont know what they are supposed to be used for. does anyone know what these tubes are meant for? and how they are supposed to be used. does anyone have any tips on keeping yucca alive?





thanks!

Flower pot tubes?
I've got a 6foot tall yucca. I've had it for donkeys. I always forget to water it (so I guess they like it dry) and it goes yellowy when i moved it away from the window (so I guess they need lots of light!) And I've never once fed it. I always thought they were relatively hard to kill. Kind of a treat 'em mean keep 'em keen type of plant.


I have no idea what the tube is. Water? Food?
Reply:just wanted to add that i could not believeeeeeeeeeeeeee that all the damned thing wanted is a bit more light. it is thriving now. the leaves are getting darker and new leaves are coming through. another problem solved. thank you so much!! Report It

Reply:If the pot you are mentioning is like the ones they sell here in Spain, the red bit is a tell-tale to help you keep the pot watered correctly. Either the red bit will show when there isn't enough water, or it is there when there IS water and you should top it up when it has disappeared.





Because the Yucca has different watering needs to other plants, you might not want to go by that tell-tale tube. Check out some sites about caring for your Yucca.





I did a search in Google for "Yucca Care" and tons of sites came up. One is this one:

I can only seem to grow Hyascinths. I manage to alternately over and under-water the rest of my plants...
