Planting root parsley

To grow properly, root parsley needs a few things going for it: sun (though it can still take part shade), soft soil, lots of organic matter and good drainage. As a result, depending on the type of soil in your garden, a little bit of preliminary work might be required before planting.

Preparing the soil

Hamburg parsley is another name for root parsleyIf your soil is heavy, meaning it contains lots of clay and is compact, you’ll have to make it lighter.
During the fall a whole season before you plant, amend the soil with extra soil mix and sand. After that, whatever the type of soil, enrich it with large doses of compost or ripe manure. Last of all, with a spading fork, loosen up the soil deep down.
In the following spring, work through the surface of the soil again to loosen it up a bit before planting.

Smart tip : if you’ve got a chimney, don’t throw you ashes away! Use them to make your soil a little bit lighter still. They’re also a great source of potassium for your vegetable patch.

Planting:
