We will be rolling out several small fixes mid-day today (Jan 29.) We do not anticipate any disruptions or problems, but f you spot any unexpected issues after 12 noon (PST), please report them in the designated thread in the DG Site Updates forum.
I have used this book extensively since the mid 80's and love it. It has educated me on many different varieties of plants, how to grow, how to fertilize, how to care for the plants, and plant requirements. It's my plant bible. I will never loan it although I've been asked to do so. And sometimes I just sit on my deck, look across my fish pond at my flower beds and read the book over and over.
This old standard (first published in 1929) is the Bible for gardening in Houston. It is a general gardening book, so many areas are treated. Some are necessarily quite brief. As it is old, it does not cover some of the newer introductions. However, it is the plant lists that have been most useful to me. They are very thorough. Indeed everyone who gardens in Houston, should, at the outset, acquire this book. The index is excellent.
