My asparagus plants are at least 6 years old I get a lot of skinny spears I think they are female spears How do I encourage thicker spears?

Do you use any fertiliser?

You can buy seeds and crowns (depending on the season) from Livingseeds in Midvaal. They have a online website with plenty of organic heirloom seeds.

I do not have access to crowns but do for seeds. How best to prepare the soil and what pH is recommended?

Bunnings sell crowns this time of year. Google seed selling companies on the net - like Eden seeds or similar. Crowns will have you 12 mths ahead of seeds. Just good friable soil ph 6-7 will grow most things or google it.

Google how to grow it. Late winter you need to cut it off at ground level. Put compost 4-6 cm.

I will be digging up crowns from an elderly friend's garden. They have been growing, as in, multiplying, over the years and now too many in the bed. I'm guessing to lift them in late winter (subtropics), however, I am not sure. The lifted crowns will then be shared by other people, so, are there any good instructions for re planting the crowns, when etc, please? Thank you very much and also thank you for your monthly email for planting, I have told so many people about your list. Wendy Strathearn Gympie Permaculture

Do it late August. Have your soil well prepared with compost and manures. Plant the crowns and water each week. A really good watering the first time or before you plant them.

Dig up late winter - mid August, break into required pieces and plant into soil with plenty of compost in the soil, Mix in some Rooster Booster from Bunnings or something similar and water regularly - 2-3 times a week. You may not have a big harvest the first year or so, depends on the size of the crown you plant.
