In yoga practice the concept of diksha — initiation or threshold — carries with it a sense of right timing and conscious understanding of readiness for the next level. For example, knowing I was not yet strong enough, this past weekend I chose not to try to jump from adho mukha svanasana (downward facing dog) to svanasana (headstand), but instead concentrated on doing the poses one at a time, even though I was surrounded by people who could do the transition with ease and my ego was challenged. Until I am stronger and better able to hold the alignment in poses at that level, I would be too much at risk of hurting my neck and shoulders.
In the garden, it is easy to be fooled by a beautiful weekend to move right to activities that are still 3-4 weeks premature. Even though it will hit 70F this weekend, it is not time to plant (other than perhaps an experimental row or pot of kale, chard, or beets, which like the cold). The best gardening you can do in the beginning of March when the weather is swinging wildly from below freezing to unseasonably warm is to read and plan and start seedlings indoors, just like it is best to warm up and work on strength, alignment, and flexibility before going for harder asana in your yoga practice. It will be tempting to get out this weekend, but do the prep stuff and the clean up.
Here are some favorite books of mine to get ready for planning. It is mostly more practical stuff (rather than the super glossy, beautiful garden as splendid art and architecture picture book reading) with some food and yoga overlap and a bias for small urban gardens.
