At Aberglasney we have to pack all our productive plants into the Kitchen Garden, which seems quite big, that is until you start to list all the things you want to grow. We have therefore spent a lot of time working out how to make the most of the space. There are a number of different ways of doing this and despite having technical names most are very simple tasks that just require some planning.
The first is crop rotation which simply means not growing the same plant in the same place; this allows you to change your layout throughout the year. New plants can then be tried and manuring and mulching can happen all year round. The second is crop succession which is closely linked to rotation and basically means replacing each crop with another one for later in the year. A third method is intercropping which is basically growing two crops in the same place and one comes out when it’s ready and then the other matures. The fourth is catch cropping which is growing a quick to mature crop. This involves growing a crop between main crops which is usually salad leaves or radish. We also use another trick which is a version of edible hedges these can be espaliers, step over fruit trees or seed grown crops. These make excellent use of boundaries or can make boundaries in themselves. It is important to remember that flowers can also be used in these displays to add colour and for ground cover.
We use all of these methods in the Kitchen Garden at Aberglasney and have found a few really good combinations of these methods. The first is to let Verbena bonariensis seed around in the herb garden. The herbs are just as good as always and you get a wonderful display of colour as well. The gaps between the herbs get filled and it reduces weeding. We find planting rows of Narcissus for spring works well for colour and interest and these are followed by Brassica’s in June or July. What is great about this combination is that you can add manure after you take the Narcissus bulbs out. Most Brassica such as Kale or Cabbage start small and fairly slow so there is the opportunity to either plant salad leaves or annuals such as marigolds under them. What we like about this combination is that if you use Calandula you can also eat the petals. Step over fruit trees make excellent hedges and the ground underneath them can be planted up with vegetables or flowers. Our main catch crops or intercrops are salad leaves and radish and our main intercrops are the same but with the addition of flowers. Courgettes are another plant where you can do intercropping or catch cropping and succession can be easily achieved with a combination of spring bulbs, annual flowers and whichever vegetables you want to grow. We find that it is very little extra work and the benefits to the production patch are huge.
