A 4 year crop rotation chart is an invaluable tool for any gardener looking to improve their soil health and increase crop yields. By systematically rotating crops to different parts of your garden each year, you can break pest and disease cycles while allowing the soil to replenish lost nutrients. Developing a well-planned 4 year rotation schedule will make garden planning simpler and lead to healthier, more productive vegetable and flower beds.
What is Crop Rotation?
Crop rotation refers to the practice of growing different types of crops in the same area across a sequence of growing seasons It works by dividing your garden into sections and switching the crop families grown in each section every year The families are rotated in a set sequence to avoid planting the same or related crops in the same soil two years in a row.
Some of the major crop families used in 4 year rotations include
- Solanaceae (tomatoes, peppers, eggplants)
- Cucurbits (cucumbers, squash, melons)
- Brassicas (cabbage, broccoli, cauliflower)
- Legumes (beans, peas)
- Root vegetables (carrots, beets, onions)
Why Use Crop Rotation?
Rotating crops each year provides multiple benefits:
-
It prevents the buildup of crop-specific pests and diseases in the soil. Many soil pathogens thrive when the same crops are continuously grown in one place year after year.
-
Different plants extract different nutrients from the soil. By rotating crop families, you allow the soil to replenish nutrients that were depleted by heavy-feeding plants the previous year.
-
Some plants add nutrients to the soil that benefit crops grown after them. For example, planting nitrogen-fixing legumes before heavy nitrogen feeders like corn can eliminate the need for extra fertilizer.
-
Changing the location of deep- versus shallow-rooted plants improves soil structure. The roots create channels that facilitate drainage and aeration.
The 4 Year Rotation Schedule
Dividing your vegetable garden into 4 sections makes planning a rotation schedule simple. Here are the basic steps:
- Split your growing space into 4 numbered quadrants or beds
- Assign each crop family to a bed number and note fertilizer or soil prep needs
- Each year, move every crop family down one bed, with bed 1 rotating to bed 4
- Repeat the cycle every 4 years
For example, your schedule may look like this:
Year 1
- Bed 1: Heavy feeders (corn, broccoli) + compost
- Bed 2: Root crops
- Bed 3: Legumes (beans, peas)
- Bed 4: Solanaceae crops
Year 2
- Bed 1: Root crops
- Bed 2: Legumes + compost/manure
- Bed 3: Solanaceae crops
- Bed 4: Heavy feeders + compost
You would continue moving each crop family forward by one bed each year.
Tips for an Effective 4 Year Rotation
Here are some useful tips when planning your 4 year rotation schedule:
-
Leave space for any permanent plantings like asparagus that won’t be rotated.
-
Avoid planting related crops from the same family together. Space them out within beds.
-
Add compost or organic fertilizer before heavy feeding crops like corn or brassicas.
-
Plant cover crops or sow unused beds with green manure to improve the soil.
-
Keep good records! A garden plan, journal or map will help you remember the rotation sequence.
The Benefits of 4 Year Crop Rotation
Using a purposeful crop rotation system offers big rewards. You’ll see:
- Less problems with soil diseases and pests like nematodes or cabbage root maggots
- Reduced need for chemical pesticides and synthetic fertilizers
- Better yields from healthy, nutrient-balanced soil
- Easier garden planning and organization
A well-planned 4 year crop rotation schedule is a simple, effective way to boost your garden’s productivity. Your soil and plants will reap the benefits for years to come.
Here’s my simple 4-year Crop Rotation Plan
My garden has 6 beds all 4 x 25 feet. Two of these beds are taken up by my strawberry, raspberry and blackberry patches.
That means I have 4 beds left to plant all of my other crops!! This is my simple 4-year crop rotation plan:
Making a plan helps me get everything I want in my garden. I group plants by family and then plant them. It’s a little too simple in the picture above—I grow more than just those plants—but it should give you the idea. Then I plant all the same plants together every year, but in a different bed. In my case, I move bed #1 down to the furthest south bed and then move the other beds up one to the north.
This simple rotation system means that every bed only sees the same crop every 4 years.

How long should a crop rotation run?
Most crop rotation schemes tend to run for at least three or four years, as this is the number of years it takes for most soil-borne pests and diseases to decline to harmless levels. If your beds are divided into four groups, this means that members of each plant family won’t occupy the same spot more than once in a four-year period.
Do you need a crop rotation plan?
You may see a drop in plant health and productivity if crops are grown in the same spot for many years. To avoid these pitfalls, adopt a crop rotation plan. The principle is straightforward enough—the same vegetables should not be planted in the same place year after year. As a system of organic gardening, crop rotation has many advantages:
