Where these tips come from

These are traditional gardening recommendations from the Gardener Planner database. Treat them as a guide: soil, light and spacing matter more for your harvest, and many pairings have little scientific evidence.

Separate plants of the same family, because they share pests and diseases.
Place tall plants so they do not shade short ones.
Keep proper spacing, as even good neighbours compete for water.
