Cucumbers are heavy feeders that grow well in the heat. They will not thrive among plants that will compete with them for nutrients. Finding companions plants for these veggies can be challenging.

Overall, cucumbers and tomatoes have similar growth patterns, meaning you won’t’ have to work extra when adding the two close to each other. Indeed, they have similar basic needs and will produce harvest around the same time if you sow their seeds the same day.

Of course, we are talking about averages here, as the final results will depend on the varieties you choose.

Additionally, both crops are warm-season and do well in well-draining soil, better if slightly acidic (the ideal pH level is between 5.8 and 6.5). So, you can grow them together without making them suffer.

Before transplanting your seedlings outdoor, consider hardening them off. The practice isn’t challenging, but it requires some patience. But all you have to do is gradually expose your plants to the outdoor conditions, increasing exposure every day by one hour.

Don’t forget to amend the ground to make it suitable for growing cucumbers and tomatoes before transplanting them. 

When the soil temperature reaches (and stays at) 70°F, you can safely place your seedlings in the ground. Choose a location that gets at least six hours of direct sunlight during the day.

Plant your seedlings 15 inches apart and space your rows at least 36 inches from one another. Don’t forget to thoroughly water your seedlings to reduce shock and speed up the adaptation process.
