Today February 22,  2011. Rich and started to divide lilies and I did 3 videos to show the benefits of planting in sand and how easy it is to divide.  You will also see how we planted them back in sand.  While in the 1st video I stated 2 years, the growth is actually at the end of the 2nd year.

We use black buckets from dollar type stores that have a metal handle.  They are 3 gallons.  Growth in 2 years is awesome

Please allow time for the video to buffer, this could take a little while, depending on you internet speed.

The size of the tuber depends on the variety of the lily.

The size of the tuber is mostly related to the size of the plant.  Large spreading lilies have larger tubers.  Smaller sized lilies have smaller tubers. Look at the photos below.

Lilies are shipped bare root because they do not travel well with leaves. So for this reason we remove all large leaves for shipping.  It is no big deal really because each lily pad only lives a few weeks before it turns yellow then brown and dies.  Lilies are constantly sending up new leaves all the time.  These new leaves  replace the leaves that have died.

Once you open the box with the lilies if you can not plant right away put the tuber in a bucket of water.  If you have city water be sure to add dechlor.   The tuber will keep for a week or more.  Change the water out of the pot if it the water becomes nasty or smelly.

For hardy lilies do not put them in your pond unless the water is at least 55 degrees.  For tropical lilies the water must be at least 70 degrees.
 

Then cover with dirt.  Then top with gravel.  Make sure the gravel comes up to the crown (the crown is where the leaves emerge on the tuber.  Do not cover the crown!

Fill a 5-gallon bucket and slowly drop the pot into the bucket so that you do not wash the soil away.  Leave the plant sit for few hours.  By doing this the loose dirt will go in the 5- gallon bucket and not your pond.

After a couple of hours remove the potted lily and slowly lower it into your pond.  Take your time so that you do not get the dirt in the water.

Many buy plastic dish pans in the dollar stores and use them for lilies.  They work great and you generally do not have to re-pot but every other year.

You want to use at least a 1-gallon  black nursery pot, bigger is better in the pot size.  For my personal lilies I generally use a 3 to 5 gallon sized pot.

In a few days if your water is at least 55 degrees you will see the leaves enlarge and work their way to the surface.

Hardy lilies can go as shallow as 6 inches or as deep at  24 inches.

If you have to buy dirt look for bags of topsoil.  It should feel heavy in weight.  DO NOT use potting soil.  It is too light and is sometime contains perilite (looks like small pieces of Styrofoam) because it will just float out of the pot.

The dirt you use should contain clay to hold together.

If your water is at least 55degrees you will see lots of leaves as the water gets warmer.  Generally speaking lilies will start blooming a few weeks after planting.  But a lot depends on the water temperature.
