A few weekends ago at the Tread Lightly festival, I picked up some asparagus plants from Frog Hollow Nursery and today my Sunday afternoon project is to plant them. I have two smallish beds at the front of my veggie patch that are reserved for perennials. The other bed has blueberries, so this one is perfect for my new asparagus patch. The soil is well drained and slightly acid so if I can get some compost and manure into it, it should be perfect for growing this tasty member of the Liliaceae family.
I consult my favourite veggie gardening book "Self -Sustainable Gardener" by John Seymour and it advises the best thing to do, to prepare the bed properly, is to single dig.
Some offerings from the ponies. |
I haven't done this before so here goes. Seeing as this is a semi permanent crop it makes sense to put the hard effort into the soil now as I won't be able to dig again once planted. I pick up half a barrow load of horse manure from the paddock and get two bags of blended and composted manure to add to it (sorry Marcus my compost is not ready yet!) I can fit 4 trenches in my space, with 3 plants in each row for a total of 12 plants.
I have chosen two varieties that were recommended to me by the nice lady from Frog Hollow that are their favourites, apparently delicious and noteworthy. They are "Mary Washington" and "Connovers Colossal".
I dig a trench to a spades depth and put the top soil to the side of the trench. I take a small selection of soil from about 12cm depth to do a soil test and set it aside to dry out as the test recommends. I will come back to this later. Next I fill the bottom of the trench with some horse manure. On top of this I add some composted manure and mix some of the soil into this. Finally I add a scoop of SEAMUNGUS pelleted seaweed fertiliser, as I read that Asparagus do well with a seaweed mulch so figure they should like this as a feeder as well and winter is the time for feeding them. Finally I replace all the top soil and hoe it into a nice raised row ready for planting.
Removing all the last of the weed runners. |
Last summer I grew Zucchini in this bed and when they finished I made sure to weed the bed thoroughly and mulch it. There is only the odd weed left and as I dig, I make sure to remove any runners I come across. John Seymour informs me that getting rid of any creeping weeds will be impossible once the asparagus roots are established and spread throughout the soil. Clearing the bed first as thoroughly as possible and mulching heavily will be my best weed suppressant.
A strong root system. |
After I repeat this process three more times I have four nice raised rows to plant into and I make quick work of easing the plants into their new permanent positions, 30-40cm apart. Now is a good time to go back to my dried soil and complete the soil test. If I need to adjust the soil (with lime for example) it will need to be applied next and watered in.
I read in the "Self Sufficient Gardener" that ideal conditions for asparagus are as follows:
"The plant flourishes in a light well-drained loam and it will grow well in sandy land that has been well mucked and composted and not allowed to dry out. The soil should have a pH of 6.5, which may mean you have to add lime."
When I do the colour i-metric test I'm really happy to see that it shows up as a pH of 6.5 (slightly acid) on the colour chart. Well - to my eye anyway- as there are quite a few orange shades on the chart, but I think that one definitely matches best! So all being interpreted correctly this means I shouldn't have to add lime or anything else to adjust the pH. Although it would have been great to be able to do a soil meter test as well to compare but I haven't splashed out for one of these yet.
6.5 pH is ideal for asparagus. |
Now it's time to lay the drippers back down, give the plants a soak and follow John Seymour's second piece of advice:
"Asparagus benefits enormously from heavy mulching. I like to mulch with seaweed, but otherwise mulch with any organic material which is non acid. Don't hoe to deeply otherwise you'll damage the asparagus roots. Your mulch is the best weed suppressor."
I have a big bag of sugar cane mulch left over from summer (no weed seeds - bonus) so lay this on thickly and use some old straw in the trenches between the rows. I will top this up as it breaks down to keep it nice and thick.
The finished job. |
I'm pleased with my efforts for today and all that's left now is a two year wait till we can feast!
