Crop Rotation

The main purposes of crop rotation are:

1. To prevent the build up of pests & diseases in the soil.
2. To aid soil fertility. (Some vegetables are heavy feeders, some light feeders). Some deplete minerals in the soil & some use less minerals up. Some plants add nutrients to the soil.
3. Suppress & control weeds.

For the purpose of rotation, veg should be sorted into their own groups within each family and rotated in 3, 4 or 5 yearly rotations. (5 being the best).

The groups are:

1. Potato: Tomato, Pepper, Aubergine. (Pepper & Aubergine can also be grown anywhere in the rotation).

2. Legumes: Peas, Broad, Runner & French Beans.

3. Brassicas: Brussel Sprouts, Cabbage, Cauliflower, Kale, Kohle-Rabi, Oriental Greens, Radish, Swede, Turnips.

4. Allium: Onion, Garlic, Shallot, Leek.

5. Roots: Beetroot, Carrot, Celeriac, Celery, Parsley, Parsnips.

The above 5 would be a 5 YEAR ROTATION (5 different areas of ground)
The next year is (1 to 5), (2 to 1), (3 to 2), (4 to 3), (5 to 4).

Some vegetables/plants do not fit into a particular rotation, These are:

Rhubarb, Asparagus, (Perrenials).
Courgettes, Cucumber, Pumpkins, Marrows, Squashes, (Curcubits) (Annuals).
Sweet corn, French Beans, Runner Beans, Endive, Chicory & Lettuce can be planted anywhere but not consistantly in the same piece of ground.

A 4 year rotation which I use would be:

1. Potato Group.

2. Legumes and Alliums.

3. Brassicas.

4. Roots.     (Year 2 = 1 to 4, 2 to 1, 3 to 2, 4 to 3) and so on.

The Last Post

As my readers will already know I moved to a new house (bungalow) last year. Much work, updating, d. i. y. and a vast amount of gardening and landscaping needed doing to the property. Most of the gardening to the rear of the property has now been completed just as the Wintery weather begins to take hold. A good sized vegetable plot is one of the features in the back garden prepared and ready to be utilised starting with next Springs sowing and planting. With this in mind I spent a couple of weeks last month tidying up N1 plot before deciding to give it up just over a week ago. Due to the amount of work on the house and gardens this year my blog posts have been just about none existent. Over the past seven years I have enjoyed reading many other allotment/gardening blogs and meeting/talking to lots of other gardeners on the "net". I hope my blog has been of interest and some use too, to all who have spent their time looking in on it. Good luck and best wishes to all you love…

Rooko's April Top 10 Tips & Tryouts

1. Clear away spent flower heads from spring flowering bulbs such as hyacinth & daffs. Don't cut away or discard the foliage as it will replace the bulbs energy for its next flowering.

2. If the weather in your area has been dry enough lately and your soil is not wet and heavy, now is the time for some rotavating/digging, adding compost/manure as required to the soil.

3. Air temperatures are still relatively unpredictable in my neck of the woods at present, it may be worth checking the germination temperatures of various seeds before sowing takes place.

4. Easter weekend was the traditional time for getting your potato tubers into the ground. Don't put them into wet soil and remember Easter weekend is early this year so another couple of weeks wait isn't a problem.

5. More overnight frosts have been happening in this part of the country recently, compared to the past few years. So if you are sowing planting this month keep cloches or other plant protection equipment a…
