Best Time to Plant Rapinis

This will depend largely on your local climate, but as a rule of thumb, begin to plant the rapini seeds in early spring or fall. This is the best time to ensure that the seedlings survive the weather.

To check when rapinis are most likely to thrive in your area, see the USDA Plant Hardiness Zone Map. If you live outside the US, do a quick search for ‘plant hardiness zone + [city]’.

How to Plant Rapinis the Right Way

There are a number of things to consider that will help you avoid some of the common mistakes of growing rapinis in your home garden.

Often overlooked, your soil can have a huge impact on how well your rapinis grow. Generally, your soil should be well-drained, fertile. Soil PH levels should be around 6.0 to 7.5.

Sow the seeds 1″ apart in rows 12-18″ apart at a depth of about 0.5″. For each plant, be sure to sow at least a few seeds to ensure that at least one of them will germinate.

Begin thinning your rapini seedlings 12-18″ apart when seedlings are 2-3″ tall.

How Much Sunlight is Needed to Grow Rapinis

The amount of sunlight is another key to a successful harvest. Too much sunlight will dry out your rapinis. Not enough sunlight will stunt your its growth or even kill it.

Ideally, your rapinis should be getting full sun.

How Much to Water Rapinis

As you’ve figured by now, a lot can have an impact on how well your rapinis do, and the amount of water is no different.

Ideally, the soil should be damp to touch; not soggy or bone dry. If the leaves on your rapinis begin to change colors or start to look droopy, you need to adjust how much water you’re giving it.

Unfortunately, if you give it too much or too little water, you can kill it, so it’s best to just keep an eye on it and water as needed.

How Long Does it Take Rapinis to Germinate and Grow?

Now the fun part begins and you get to watch your rapinis grow.

It takes approximately 7-14 days to germinate, and a total of 40-60 days from seed to harvest.

When to Harvest Rapinis

The best time to harvest your rapinis is when buds are justabout to flower.

Rapinis can grow up to about 18-24″ tall.

What Can Rapinis Be Used For?

Food Use: typically sautéed, added to pasta, or used in stir-fries.

Flavor Profile: rich, nutty, bitter flavor.

Can Rapinis Grow in Pots and Containers?

Yes, you can plant up to 1 plant per 12″ container. This can help control weeds and keep your plant from growing out of control.

It also gives you the flexibility to move your rapinis around if you need to adjust sunlight or bring it indoors to avoid harsh weather conditions.

Are Rapinis Safe for Bees?

Yes, rapinis are safe for bees.

According to, bees pollinate human food crops that make up about 90% of the world’s nutrition.

Given their importance in our ecosystem and food supply, it is important to note that growing rapinis is bee-friendly.
