Crop Rotation & Plant Families

This is a collection of things that I have found on the internet to help me make sense of what should be planted in what order. Lots of gardeners have been doing this for years so I figure that the knowledge that is out there should be used. I will need to be gardening for years before I have anything original to offer – if ever.

 

Plant Families

The Solanaceae Family – includes potatoes, tomatoes, capsicums, chilis and eggplants.
The Brassiaceae Family – includes Asian greens, cabbage, broccoli, brussel sprouts, cauliflower, turnips, mustard and radishes
The Apiaceae Family – includes carrots, coriander, parsley, parsnip, dill and caraway.
The Fabaceae Family – includes peas, beans and other legumes.
The Cucurbitaceae Family – includes pumpkin, zucchini and cucumbers.
The Amaranthaceae Family – includes spinach and silverbeet
The Asteraceae Family – includes lettuce and artichokes
The Chenopodiaceae Family – includes beetroot and quinoa
The Poaceae Family – includes sweetcorn and maize
The Alliaceae Family – includes onions, chives and leeks

Light Feeders – include onions, leeks, garlic, beetroot, carrots, parsnips and silverbeet

Heavy Feeders – include potatoes, tomatoes, cauliflower, broccoli, cabbage, sweet corn, lettuce, cucumbers, zucchini, spinach, lettuce and Asian greens.

Planting in 4 steps

I don’t necessarily devote whole beds to each vegetable type, but I do try to follow this rotation when deciding what to plant next in a section of the garden. I also take into account the plants that seem to like each other like basil and tomatoes or carrot and onion and fill spaces between slow growers like garlic with radish. Cucumbers go really well underplanting corn.

I plant in this order:

1 . Legumes – These will grow in soil of average fertility. They leave  nitrogen in the soil which will be used by the crops that succeed them.

  • peas, snow peas, broad beans, runner beans, snake beans and okra.

Next

2. Leafy Green Vegetables – Those of which we eat the leaf. These need high levels of nitrogen to grow fast and sweet. They are heavy feeders.

  • lettuce, silverbeet, cabbage, cauliflower, broccoli, sweet corn, cucumbers, zucchini, spinach, chicory, endive, jerusalem artichokes, celery and Asian greens
Next

3. Edible fruitsThese require a humus-rich soil with a balanced fertility.

  • tomato, chilli, capsicum, corn, cucumber, eggplant, squash, pumpkin, melon
Next

4. Root Vegetables – Plants that produce an edible root, tuber or rhizome. These require less of the nutrient nitrogen, but more potassium for good root growth.

  • potato, radish, onion, carrot, beetroot

 

6 step crop rotation, sweet soil lovers -> n-fixers -> high-n -> moderate-n -> tenders -> acid soil lovers.

sweet soil (sweeten with lime a month before planting) onions, leeks, lettuce, carrots

legumes (the Nitrogen fixers) •peas, potatoes, beans

leafy greens (brassicas and high-Nitrogen friends) •cauliflower, broccoli, thyme, (kale?)

roots (moderate-Nitrogen) •carrots, parsnip, beetroot, leek

tender •corn, pumpkin, zucchini, sunflowers

acid soil • tomatoes, capsicums, parsley, chives

 

6 Year Crop Rotation using green manures

USING FALLOW AND GREEN MANURE (slash & mulch)…

resting’ the soil in a garden bed for a growing season, producing no crops from it for that time although they may add compost, so giving the soil time to build up nutrients; you will need to make an additional ‘fallow’ bed planting a ‘green manure’ crop such as a legume or a legume-fibrous grass combination, like vetch and oats. These are grown then slashed just on flowering and left as mulch or turned into the soil to add organic matter, to increase nutrients and help retain moisture in the soil.
