I've seen these intercrossing gardening spreadsheets that shows 3 different plants. Do you have to grow 3 plants side by side, or the first plant and one of the other 2 listed side by side? So do I plant 2 plants adjecent or 3? I keep seeing people say they intercrossed by planting this plant and another plant which makes me think 2 garden patches side by side, or do I plant all 3 of the plants listed side by side?
