Companion Planting Basics

Stick around and you'll learn the one trick that actually keeps root nematodes at bay, plus a handful of practical pairings you can start using in your kitchen garden today. I'll walk through what really works, what’s mostly myth, and how to avoid common planting pitfalls, all in a friendly, no-jargon style.

Does it really work?

Here’s the thing: plants can genuinely help each other by shading, sharing space at different times, or attracting helpful insects. Those are solid, observable effects that gardeners have used for ages. The rest, like basil magically sweetening tomatoes or veggies hating each other, are mostly folklore from old gardening books, not solid evidence.

Tomato companions

When it comes to tomatoes, think of a layered garden. Plant mooli or radish between slower cauliflower or band gobi, so the radish harvests before veg takes all the space. Alternate rows of spinach and coriander, they share water needs and season, making care easy. And onions or garlic next to carrots work because their root shapes use the soil efficiently, if the pest-repellent buzz is weak.

Marigold reality

Marigold gets a lot of hype in South Asian gardens, but the science is narrower than the folklore. Planting a few marigold flowers among tomatoes won’t stop root-knot nematodes. What actually works is a dense stand of French marigolds grown for at least two months before you plant the vegetable, then clearing them away. This timing gives the most reliable nematode suppression.

Marigold timing

The key number to remember is two months. That’s the minimum period you need to grow a thick marigold crop before transplanting your veggies to keep root nematodes at bay. Anything shorter, and the benefit drops dramatically. So mark your calendar and start the marigold bed in early autumn or late winter for best results.

The one nematode trick

Here’s the one nematode trick you can try right now: sow a block of French marigolds thickly in the bed where your tomato or bhindi roots showed knotty swellings last season. Let them grow for at least two months, then chop them up and dig them into the soil, wait a couple of weeks, and finally plant your new crop. Rotate the next season to a less-susceptible family for safety.

Good veg pairings

Now, the part most people miss: pairings that respect growth speed and root depth. Plant mooli or radish between slower cauliflower or band gobi, so radish harvests before veg takes all the space. Alternate rows of spinach and coriander, they share water needs and season, making care easy. And onions or garlic next to carrots work because their root shapes use the soil efficiently, if the pest-repellent buzz is weak.
