Rick,
Thank you for the tips. I am a quick study and I do my homework, LOL!
I do have very sandy soil, so I hope I will not run into drainage problems. I researched online and in books before planting my bulbs, and I read that in sandy soil in colder climates it is better to err by planting too deeply rather than too shallow. It supposedly gives them added protection from frost heaves, keeps them cooler in the summer heat, and the bulbs will also spend less energy adjusting their depth since they tend to grow naturally deeper in light soils. I don't know if any of this is true. Since I have never grown lilies before, I hope I did not make a horrible newbie mistake.
In Ed McRae's book, he recommends planting as deeply as possible (covered with soil 3-4 times the depth of the height of the bulb from base to tip) and states that large bulbs can/should have 10 inches of soil covering them.
It has been such a warm fall here that I am not sure when will be the best time to mulch. We have not even had a frost yet of any kind.
