Hi Michael, welcome to the forum . Glad to see another Texan on board. As for varieties other than what you have , You might try Celeste & Marseilles Black VS (top two in my book) to start with and there are many other to add down the road if you have the space. Violette de Bourdeaux is a must have in most collections. The main thing is you want to stick to tight eyed, rain tolerant varieties that can hold up in humid weather.
Ditto what others have said about RKN, be sure & check. Also check all plants before you buy them and if your sandy soil is contaminated, be careful not to contaminate your potted figs by sitting them on the soil. Good Luck.
As for rooting, Jon's New Baggie method is easy for most figs, but for treasured rare varieties and hard to root varieties, sphagnum in baggie method is the way to go. There are many other ways to root figs too, but, you'll learn through trial & error which is best for you, like most of us have. Keep reading the old posts, they contain a wealth of information.
