I must be terribly old-fashioned because I do not have a computer program to plan my garden.
Planning? Mostly I look at what's in my bag of seed packets, look at the garden, look at the seed packets and start digging.
It helps to plant more or less the same variety of vegetables year after year. With nine beds, it's not too hard to rotate. Sometimes it's not easy figuring out where all the big tomato plants are going to go. But more often than not I end up with empty spaces, wondering what I can fill them with. (There have been times I wished I didn't have so much lettuce.)
My basic tools are some thin bamboo poles for dividing the beds into squares, a tape measure and a spiral bound book where I record what I have done. I've gotten pretty good at planting freehand, meaning moving my bamboo poles to create fairly precise little areas in which to plant a few radishes, say, or carrots or an area of several different varieties of lettuces.
Not far away is my book where I sketch out the bed with pencil, then make notations on what is planted in the squares and the date it was planted. I've never had to buy labels for my garden beds. Whenever I need to remember what I've planted, I just pull out the book. It also works as an excellent log. If I need to know planting dates, for instance, the book tells me instantly. I can also make notes on how long things took to germinate, which varieties did well and which didn't.
I'm not sure this would be so simple on the computer. But maybe there are some laptop gardeners out there who know better.
How do you keep your garden records?
