2/ Start as You Mean to Get On
With regular trips in mind, start as you mean to go on. Get into a routine from day one, and try and arranged aside the same time every day to visit. If you can produce a habit, this will help see you through before the end of the season.
3/ Take into account the Future
One particular thing that I regularly overlook is that a greenhouse is for more than just sowing seed in the Spring. When those seeds have shifted to their new home in the veg bed, the greenhouse provides an invaluable space for other crops, such as tomato vegetables and cucumbers, as well as extending the growing season into Autumn. Put together and grow crops for this reason too.
