Crop Rotation for Raised Garden Beds

Crop Rotation for Raised Garden Beds

The idea of crop rotation for raised garden beds is a very important issue and is a task that needs to be adhered to as often as we possibly can. This situation would come into play if we have a few raised bed gardens and we plant a lot of vegetables. This method of alternate growing is a detailed and disciplined approach to growing our own veggies, it’s also a systematic way of managing and maintaining our raised beds. The rotation  ensures that firstly the soil can be replenished after growing a certain crop and secondly, that we can attempt to eliminate certain viruses and garden pests that may attach themselves to certain root vegetables.

The rotation can last or go on for 3 years and may extend to 5 yrs or more in some cases, depending on how large a garden scale we are working with. If it’s a case that we have only one raised bed, we still need to carry out this practice as best we can. In this instance we change the planting and sowing arrangement that we had from the previous year. For example, say, we planted tomatoes in the right hand side of our raised bed, we have got to plant these toms. on the left hand side the following year. The year after that, we could plant them towards the centre and back to the RHS the year after that. etc etc.

 

Crop rotation in raised beds

 

How does crop rotation work:

 

Like we mentioned above, all crop rotation schemes seem to run for at least three to five years, because this is the number of years that it takes for most soil living pests and growing threats to decline to workable, harmless levels. If  we have three or four raised beds this means that some varieties of each plant family won’t occupy the same spot more than once in a four-year rotation. However there are certain exceptions to this system and they could be rhubarb, artichoke, and some fruit bearing shrubs like gooseberries, blackberries and perhaps in some occasions, strawberries. These varieties are somewhat immune to these pests and diseases.

 

Organised crop rotation;

 

The well organised gardeners and those who have been gardening for some time will have their stall well set out over the years and will have this practice off to a tee. The longer we would be gardening, this practice of crop rotation would in most cases look after itself and would naturally become seamless after a while. The best system that pro. or seasoned gardeners use would be to divide the crops or vegetables into different groupings. This eleminates a lot of confusion and worry in the start of our gardening adventures and clearly defines what is required to manage this type of gardening.

Vegetable groupings;

 

We will have at least four main groups of vegetables that are very easy to remember and to easily distinguish from thr others. The first group would be the climbers like peas, broad beans, runner beans, so this is an easy way to recognise these. We may need a trellis to support some of these vegetables and earlier on we wrote a post on how to accquire or erect these frames, which can be read here. The next category would be the root vegetables like carrots, swedes, shallots, onions, parsnips and potatoes. As these are known as root vegetables, ie, they grow under the ground, so again they are fairly distinguishable.

Thirdly we have the fruit plants like tomatoes, squash, melons, courgettes, and again rather easy to identify these as their fruit are visibly overground. Finally we have the green leafy brassica types, such as cabbages, cauliflower, brussel sprouts, kale, chard and so on. From the above description, we can see that it’s so easy to seperate each and if perhaps, we were growing this amount of vegetables, we would have a four year rotation for each group.

 

The advantages of crop rotation;

 

Lets begin with a few of the most important benefits of crop rotation in raised garden beds, which would be the elimination of soil contaminating pests or risks. As some of these pests take a few years to materialise and manifest themselves in the soil, by moving the vegetables around we can eleiminate this risk before it takes hold. The other important issue is that the soil can replenish itself, if given the chance. Some vegetables are vigorous growers like potatoes , tomatoes, some peas and beans, thus the demand on the soil is extremely high and in these cases, rotation is necessary. That way the soil will have a chance to re-generate and re-invigorate itself again for the next crop that we will sow here. Nutritional additives will be required to assist in this process in the form of organic fertiliser, farmyard manure and well composted material. Often the roots of some of our vegetables are left in the ground and after the winter months, they will have decayed into the soil and are thus a great benefit and help in re-enriching the soil of our raised beds;

 

Crop rotation with raised beds

In summary;

 

The basic principal of crop rotation is not to have the same vegetable growing in the same area for two years running. If we can adhere to this simple principal, we will eliminate a lot of risks and difficulties that we may encounter whilst growing our own vegetables. If we do make the growing alterations, its important that we replenish the gardening space that we have used, in order to bring that area back to the original standard. Its the same principal that is used for open ground gardening or if we are using raised garden beds.

Crop rotation sounds complicated and difficult, but really if we stick to the basic principal of moving on our vegetables year after year, we will be fine. Some people who garden on a large scale will use charts, analytics and keep records, which is fine and is necessary to keep track of all the different metrics. The over-riding reason for this practise is to preserve and sustain the health and productivity of our gardens .

Happy gardening to all.

  1. I never really thought much about rotating a garden crop every couple years. I grew up with a garden, and we always had the same plants growing in the same place year in and year out. Would it hurt anything to change the crop location each year. Since they do not grow year round, I thing for me doing a little rotating each year or different crops all together would be something I do.

    1. Hi there again

      Many thanks for dropping by and reading this post, it’s greatly appreciated. Yes, crop rotation for raised garden beds is something that a lot of people use on an annual basis, especially if they are growing a large number of vegetables and perhaps have a few raised beds to deal with.

      To use crop rotation would make great sense and would help greatly both your harvest yields and the soil. Some veggies are more vigorous growers than others and as a result may leave the soil a little depeleted and this would effect next years crop. But by rotating helps out with this dilemma as it gives the soil a chance to regenerate and recover.

      Hope this explains this post and why its an important issue, especially if we are growing a lot of vegetables.

    1. Hi there Stephen,
      Many thanks for dropping by and reading this post, its greatly appreciated.
      I am glad that you found the post informative and useful, for your gardening issues. I agree with you 100%, its a great idea to do some crop rotation, from time to time as it will give the soil a chance to recover in some areas of our garden.
      Thanks again for stopping by,

  2. I heard that crop rotation is an extremely traditional practice people did back then before fertilizers were invented. This reason this is done is because some plans tend too bring nutrients back into the soil. I just didn’t know that this also serves as pest control. Its also very interesting that common crops like tomatoes and potatoes drain the soil like crazy. I have something to add. I have heard of something known as worm farm which is really good for fertilizing soils. Its also ten times better. Can you write something about that also?

    1. Hi there WinBill

      Many thanks for dropping by and reading this post. I am glad that you have found this post interesting and informative. Yes, I agree with you that this method of farming was practiced years ago and believe it or not, it’s still being done today. It would be very popular with growers who grow a lot of vegetables, have a few raised beds or perhaps have a large garden.

      It does give some areas in the garden some relief and some time to recover and regenerate after having grown  certain varieties.

      I have heard about these wormeries and their benefits to gardening. Its a great way of enriching the soil and its also a natural process. I will be doing a post on this topic in the near future, so do check back in, later.

      Thanks again for stopping by,

  3. I loved this article! I have been working with raised beds for a long time and just made one again this year and I don’t think I have ever heard of crop rotation. It was very informative and I loved all of the ideas. I will consider this for next years planting on here they should be located next.

    1. Hi there Hannah,

      Many thanks for stopping by and reading this post, its greatly appreciated. I am thrilled that you a liked this post and also that you have found some extra useful information, that will hopefully make your gardening experience much more enjoyable.

      I see that you use raised beds yourself and this post may give you a greater understanding of how to get the most from using this method of gardening.

      Thanks again for stopping by,
