呵呵~森林没种植睡莲，只好听古哥哥说：
睡莲是用盆子种植，土表放砂石稳固泥土，直接放进水池，行！
冬天可移入车库，或放块木板，用毯子包裹水缸，初春回暖就要趁早移走毯子。
睡莲-室内养植花卉介绍

睡莲的栽培一般在4月份进行。庭院水池种植，首先将原有睡莲根茎用花铲切分成几块，保证每块带三个以上新芽。选用大口花盆或箩筐，下部装部分掺入基肥的培养土，将分好的睡莲放入，四周用水池或河塘中湿泥填实，用铁丝捆扎几道，以防入水后浮出。将花盆放入水池中，将水池逐渐放满水，半月后即可展叶生长。
家庭栽培睡莲。可选用高约50厘米的大口缸，缸内首先加入约15厘米的培养土及腐熟的基肥，然后将原有睡莲的地下茎，带新芽切分成几段植入土中，再覆土5厘米，浇透水置于阳光充足处。待发芽后随叶柄的生长，逐步增加水的深度，至与缸口平，正常生长一般7月份即可开花。
How To Plant a Water Lily

Winter Care of Water Lilies

Hardy water lilies are truly hardy to about USDA Zone 4, but potted water lilies will still need some protection. You don’t want them sitting in your water garden if it freezes solid or even if it tends to freeze and thaw repeatedly. Here are some ways to keep your hardy water lily alive through the winter.
1. Hardy water lilies will go dormant for the winter. The foliage will die back or become sparse. When this happens, move the water lily, pot and all, to the deepest part of your pond, where the water doesn’t freeze solid. Hardy water lilies actually enjoy a cold, dormant period.
Leave it there for the winter and fish it back up as the water warms in the spring. It should resume growing sometimes around April.
2. If you don’t have a deep enough pond to keep the water lily below the freezing level, you can try one of these other methods to protect it.
1. Take the water lily out of the pot and bury it completely in the ground. Mark the spot, mulch it well and dig and repot the plant in the spring. (I’ve never tried this and suspect a lot depends on the type of winter you have. A good snow cover should keep it fine, but a dry, cold winter could kill it.)
2.
If it’s a small pond, you could insulate the whole pond by covering it with boards and then a layer of straw or old blankets or rugs. Be sure to remove all the coverings as early in the spring as possible or it will heat the water and cause premature sprouting. (This sounds like a lot of work, but think of all the work you save by not having to scoop leaves and debris out of the pond in the spring.
3. Bring the water lily indoors for the winter and store in a cool basement or heated garage, about 50 degrees F. Either bring in the whole pot and place it in a plastic bag or box. Check it periodically to make sure the soil remain moist. Or remove the plant from the pot and store the tuber in moist peat moss or leaves. (I’ve done both and had good luck. Don’t expect your potted water lily to make a good houseplant. It still needs to go somewhat dormant and won’t be particularly attractive.)
