Five reasons to consider planting Jerusalem Artichokes

Spring is beginning to raise its beautiful green head above the parapet and with it our green fingers begin to itch to get in the soil. Winter time is a great time to plan your next gardening adventures and in case you have a wee bit more room in your beds, I’m going to sing  the praises of Jerusalem Artichokes.

They’re Beautiful. Even someone as dedicated to the mantra of “everything must first be edible and useful” will admit, it is difficult not to smile when the sunny yellow heads of this Sunflower relative are in bloom.

Protection and improvement of cropping. Standing at up to 2m tall Jeruselums make an excellent semipermeable wind break for your less wind tolerant crops. Planting these in a row on the winds prevailing side can shelter more delicate crops and help increase yield.

Crop well with little fuss. Every gardener needs a crop that is less fussy and provides abundance whilst being low maintenance. These guys are it.

Easy to harvest. Once the tops begin to turn golden and the bite is in the air all you need is a fork to lift the lovely tuber and brush off excess mud.

Grade A hotels. Once harvested the stems of the plant should be left in situ. Their hollow stems make great over wintering “hotels” for our beneficial insect friends. This gives your garden a head start in the spring as your good guys are in the correct geographical region to nip out any of the bad guys who have overwintered in your soil. After the risk of frost has passed, the insects will have moved out of the stems, the stems can then be added as an excellent carbonaceous element to your compost pile, completing the circle.

An excellent alternative starch. Jerusalem Artichokes are very versatile in the kitchen and their lightly nutty taste is quite a winner. They can be grated raw as part of salad, sliced and lightly steamed to add crunchy to a stir fry, pureed or scrubbed and roasted with rosemary and sea salt as an attractive side. Some people do experience wind with eating them, so it is best to eat small amounts at any one time.

Readying rhubarb for the coming spring

Here in the United Kingdom Rhubarb enjoys a rather prestigious place in the culinary calendar. The pale pink slender stems of “Champagne Rhubarb” are both the ushers of spring and the first reliable cash crop of the year. No matter how much is grown at Organic Lea, the demand far outstrips the supply our mere 2 acres of diverse intensive farming can produce.

Champagne Rhubarb production is lucrative, but it can also be relatively expensive as the crop is grown in heated forcing sheds. Currently, nine square miles of West Yorkshire, is known as “The Rhubarb Triangle” and encompasses twelve farms. In 2010 these farmers approached the European Commission’s Protected Food Name scheme and were awarded Protected Designation of Origin status (PDO) for the term, “Yorkshire forced rhubarb.” Forcing Rhubarb is big business for some, however it can be done with some success in a low tech way small scale using your netting wires and a blackout cloth.

For many growers,  Rhubarb is planted once. It’s widely accepted that some vegetables like Rhubarb, Asparagus and Jerusalem Artichoke, stay put when planted and remain indefinitely. Many successful allotments and growers subscribe to this thinking and harvest successfully year on year. Organic Lea is committed to using two of it’s acres to intensive organic farming and rotation is a key element in keeping both plants and soil healthy. This means that even crops that traditionally stay “forever” in one place are included in rotation, albeit for these crops they move once every four years.

This is year four for our early Rhubarb crop and the first year of it’s rotation, so this week we uprooted one of the four rows of Timperley Early and began the process of splitting and moving it to the area of the farm called The West Bank, or Salad Terrace. Over the years, the team have noticed that the Salad Terrace is the coldest plot on the farm. It is also the most over run with Horsetail. The thinking is, that Timperly Early will not suffer from the slightly colder micro climate and that with it’s maturity it’s wide leaves may also slow the rampant encroachment of one of the world’s oldest known “weeds.” Both of these factors have inhibited the Asparagus from reaching it’s full potential so we are effectively preforming an experimental swap of the two.

Splitting the Rhubarb serves two purposes, the first and most obvious is propagation. Mature crowns are quite easily split to produce multiple plants. To do this effectively one only need ensure each split contains both root and bud, we leave two to three buds in a spit.

The second reason for splitting is to cut away the heart. This may seem counter-intuitive, however the older a plant is, the more susceptible it becomes to disease. By lifting and splitting the crowns and cutting out the old growth we are taking preventative measures against potential disease in the crop. The oldest part, or heart then is added to our compost completing its circle.
