|I bought two Agapanthus this spring and am attempting to overwinter them in my house. I was told to put them in a north window and water sparingly, but I've gotten other conflicting reports. I figured that a north window, especially at this time of year, means low light and since I don't have a north window I decided to put them in the basement near a small window. I am a little worried that this isn't the correct thing to do. Exactly how much light do they need or how little light can I get away with? since they are large plants, I don't exactly have lots of room for them and would like to use the basement if possible. Could I put them under a grow light? Thanks for your help!|
|Some of the discrepancy can be attributed to the fact that there are two different groups of agapanthus. One group defoliates and rests naturally during the winter, the other group is evergreen.
The evergreens would be kept under cool greenhouse or conservatory room conditions, meaning a very bright location but with temperatures in the 55 to 60 degree range. In a basement, you could experiment using ordinary fluorescent bulbs kept close to the plants and running for about 16 hours or so each day. During the winter, water lightly.
The others would be kept cooler (at say 40 degrees) and allowed to rest for the winter. This latter group could do well in an unheated, cool basement. Since they have no active foliage, these do not need special light. The soil should be kept just barely moist, meaning not allowed to go dry as a bone, until they resume active growth in the spring.
