fruit tree guilds - San Diego Permaculture (San Diego, CAHi Marianne, When planning fruit tree guilds the main points to consider in choosing guild plants include: Choosing plants that attract pollinators, discourage pests, boost soil tilth and fertility, reduce root competition, conserve water, balance fungal populations to counter disease and grow well in your climate. The trees you mentioned can all be included in guilds and the guava and grape vines can also be included in hedges and the vine layer of an edible food forest. The central element of a Fruit Tree Guild is the Fruit Tree! Next, consider the grass suppressing bulbs. Insect and bird attracting plants are the next choices to be considered. Mulch plants are the next choice to make. Nutrient accumulators are plants with deep tap roots that dredge up important nutrients such as, potassium, magnesium, calcium, and others. The last, but very important plants to consider for your fruit tree guild are the nitrogen fixers. Well, that’s a long answer to your question Marianne! Good luck!
