Anise, plant with basil. Anise will cause the essential oil production of basil to increase.
Anise- avoid basil, carrots or rue near anise if growing for healthy anise.

-If you grow herbs like basil, cut the top third of the plant off every time it tries to bloom. This will encourage the plant to keep putting on more foliage which you can dry and use in the kitchen.

Plant near: Beans, all garden crops, Broccoli, Kale

Phacelia — An essential element in any organic gardener's toolkit, this multi-purpose annual flower is fast to mature, and amazingly attractive to a host of pollinators and beneficial insects. Notably, it attracts bees and predatory hoverflies to improve pollination and combat pest insects. Plant Phacelia around any crop showing poor pollination, particularly squash (including zucchini and pumpkin), melons, and cucumbers.
