|I planted some climbing lily bulbs (G. Superba) in a pot. I think I over watered (every morning) and may have rotted them. How long does it usually take for the vine to sprout/germinate?|
|While waiting for Gloriosa lilies to come out of dormancy, they need only slightly damp soil until they come into active growth -- so daily watering is probably far too wet. If there is a lot of sand or perlite or similar material in the potting mix so that it is very well drained, they may still be okay although you did not mention how long you have had them and been watering daily. You could gently and carefully dig down and see if they have rotted. If they are still firm and do not smell, they are probably fine.
Once they begin to grow they prefer a moist soil and plenty of sunlight, so the larger they are in relation to the container and the warmer the weather the more you would need to water.
Along with slightly moist soil, temperature is also important. They need a warm temperature (minimum 60 degrees at night, warmer in the day) to start growing. Keep in mind the soil temperature can be about five degrees cooler than the room temperature, so try to put them in a warm location. Depending on the temperatures it can take a few weeks or longer to see any growth. Once the weather settles and nights are warm you can put the container outside.
