Will jalapeno a plant make tomato spicy?

No, planting jalapenos near tomatoes will not make the tomatoes spicy.

Here's why:

* Spiciness is determined by capsaicin: The heat in peppers comes from a chemical called capsaicin, which is produced by the plant itself. This chemical isn't transferred through the soil or air to other plants.

* Cross-pollination doesn't affect flavor: While some plants can cross-pollinate, this primarily affects the seeds of the plant, not the fruit itself. So, even if a jalapeno and tomato flower are pollinated by the same insect, the tomato will still taste like a tomato.

However, planting jalapenos near tomatoes can have other benefits:

* Pest control: Jalapenos can deter some pests that might bother tomatoes, like aphids or whiteflies.

* Companionship planting: The combination can create a more diverse and appealing garden.

So, while planting jalapenos won't make your tomatoes spicy, it can be a helpful companion planting practice.
