Here is the BEST Time to Transplant Mustard Greens in Iowa (2023 Guide)

Do you want to transplant mustard green plant seedlings, but don’t know when the best time is to?

Transplanting mustard green plants is not as easy as it seems.

Here’s why:

  • New mustard green plants must be consistenly watered, receive at least 8 hours of sunlight a day, & be kept at a temperature of at least 70 degrees Fahrenheit both inside and in a garden.

So if you don’t consistently water them they will quickly wilt. If temperatures consistently fall below 70 degrees Fahrenheit they won’t grow and may even die. And if they don’t receive at least 8 hours of sunlight the plant itself won’t grow.

  • Because Iowa’s growing season is not long enough, you have to start your mustard green plants indoors and then move them into a garden.

Because of this, I’m going to teach you the ideal time to transplant mustard green seedlings:

When to Transplant Mustard Greens

There are two different times you’ll need to transplant mustard green plants.

First, you should transplant your mustard green plants from a peat pot to a larger (5 gallon) gardening container once your mustard green plants get between 3 – 5 inches tall. This will take approximately 6 to 8 weeks after you first plant your mustard green seeds.

The second time you should transplant your mustard green plant is when you move it from indoors to your outdoor garden. You should transplant your mustard green plant into a traditional garden or raised garden 10 – 14 days after the average last frost.

Iowa Frost Dates

To help ensure the greatest success of your mustard green plant thriving you should:

  • Slowly acclimate your mustard green plant to the outside environment. Move your mustard green plant outside for one hour a day and increase this an hour every day until it can withstand mother nature for 8 straight hours.
  • After transplanting your mustard green plant into your garden provide a thick covering of mulch to help it ward off cold, disease and pests, and better retain water during the summer months.
  • Cover your mustard green plants with burlap or a protective covering if you notice that a late frost may occur to protect it from wilting and dying.
