I like to know the names of the plants I grow. It's this really dumb thing, but it's important to me. I don't have to know the name of every individual, but when I plant Suzy Q Peas and I also plant Danny Boy peas, I want to know which is which. I've used some big painted wooden stakes, marked with paint markers and they seem to hold up well--does anyone have better suggestions?
i split thin bamboo we grow, they end up about 1-3 ft long and 1/2 inch wide. they last about a season which works for conventional veggie gardens.
In a polyculture plant environment, if one has more than one variety of a plant, how does one keep them from pollinating with each other, so that the seed remains true to type?
eventually they everything related will be cross pollinated, and overtime producing a unique variety(s) to your garden. if you select for the plants you favor, you benefit in the long run greatly by having exactly what you like. there will always be variety to choose from as nature doesn't grow single variety plants. when you get into enough space and individual niches as you said multiple unique varieties can develop in different microenvironments.
if you want to try and keep specific genetics separate in a true forest garden its going to be hard.
