In the post “How to grow asparagus in your garden” we mentioned that you can grow asparagus from seed or you can plant one or two year old crowns or transplant seedlings.
In case you don’t know, a crown is the root system of an asparagus plant. These crowns can be one or even two year old. You can order them online or buy them in your local nursery or garden center. It is best to plant them in your garden upon receipt, but sometimes the weather does not cooperate. If you receive your crowns fresh you will be able to hold the crowns for two weeks without refrigeration. Store them in a cool, dry location. Soak them in water before planting, if they start to dry out.
By using crowns or seedlings you will speed up your asparagus growing process for one year, but keep in mind that there is always a risk of failure when it comes to transplanting. There are around 10%-15% of failures for one year old stock and as high as 20% for 2 year old stock. So this can end up as a expensive lesson.
Growing asparagus from seed, on the other hand, gives the best viability, with a survival rate of around 100%. Also, with direct sowing there is no root shock to delay root development.
If you choose seeds the best time to sow them is around mid-April when the ground is warm enough. A good tip is to soak the seeds in water for a couple of hours before planting. This will speed up the germination process considerably.
So, to summarize I’ll say that growing from seed is the cheapest method but it is more time-consuming. It will take you an extra year to get a crop, but asparagus grown from seed will have almost zero failure rate.
