Crop Rotation: What to Plant After Tomatoes

19 Jun


Wondering what to plant after tomatoes? Crop rotation is incredibly important, as it optimizes the what to grow after tomatoesnutrients in your soil, and will assist you in growing delicious tomatoes.

Farmers world-wide have been practicing crop rotation for centuries. The reason for this is that they discovered long, long ago that by growing certain crops in a certain sequence, they were able to optimize the precious resources of the soil.

If one crop is grown season after season, year after year, without a break, the soil will tend to deteriorate in both structure and the content of nutrients. But if crop rotation is practiced correctly, each subsequent crop will add nutrients to the soil that were used up by the previous crop. Crop rotation also minimizes the risk of nematodes and disease.

We cover crop rotation in great detail in our best-selling tomato growing guide, How to Grow Juicy Tasty Tomatoes, so why not grab a copy and become an expert yourself?

What to Plant After Tomatoes

The simplest rule of thumb is to grow an above-ground crop and then a below-ground crop. Better still rotate the four crop groups that benefit most from crop rotation. These are:

  • cruciferous crops including cabbages, cauliflower, broccoli, Brussels sprouts and kale,
  • root crops including beetroot, carrots, parsnips, salsify and turnips (remember that potatoes are NOT a root crop, they are a tuber),
  • solanaceous crops including both tomatoes and potatoes, peppers and eggplants, capsicums and chillies,
  • leguminous crops that include all the beans and peas you can think of.

Cucurbitaceous crops – cucumbers, pumpkins, squashes and marrows, and various melons – and various other miscellaneous crops – from Swiss chard and spinach to leeks, celery, lettuce, endive and artichokes – can generally be included anywhere, unless of course they make a bad companion plant to others planted at the same time.

Beans are a good crop   to grow after tomatoes.

From this you will see that legumes and then the cruciferous crops, including brassicas, are what you should grow after tomatoes.

Legumes are known to trap nitrogen in nodules that form on their roots, adding nitrogen to the soil. But this benefit is only realized if the whole plant goes back into the soil. Harvesting the pods minimizes the nutrients, so leave some plants to die and rot.

Leafy vegetables use up loads of nitrogen – which is why you should plant the brassicas after growing beans and peas. But you will still need to feed the soil and add manure and compost for the crop to really thrive. If they do thrive, leafy vegetables will generally enrich the soil with phosphorus, which the root crops thrive on. The root crops then leave behind some extra potassium that our tomatoes love!

Another factor to consider, particularly in terms of solanaceous crops, is that the different types should ideally not be grown within three years of one another. So if you want to grow tomatoes, potatoes, peppers and aubergines, you’ll need to plant different areas at different times, rotating the crops differently all the time.

    I just read a very funny blog about growing tomatoes on a balcony in Fl.  I think you'd like it.

      Thanks Frank, it’s hilarious!

    Can tomatoes be planted the following season after growing brassicas in that bed or do legumes have to be planted in between. Thanks Trish

    • Annette Welsford

      Hi Trish. Good question. You could plant tomatoes the following season, however brassicas do use a lot of the nitrogen in the soil, which is why legumes are usually planted before brassicas. So if you want to plant tomatoes straight away, I’d suggest you dig through some quality rotted manure and compost to nourish the soil for 4-6 weeks before you plant tomatoes. They only need a good dose of nitrogen to begin with, then their needs change to other elements. We provide full details in our Nutrition chapter of How to Grow Juicy Tasty Tomatoes book.

    Just a quick question on tomatoes, does removing the leaves really make a difference to the quantity and quality of the tomatoes?

    • Annette Welsford

      Hi Warren – you don’t remove all the leaves, but rather tip prune. Removing all the leaves will expose the fruit to sunburn on hot days. We have a whole chapter of pruning in How to Grow Juicy Tasty Tomatoes – with images so you can see exactly what to do.
