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.

Check around your area what varieties are grown - internet, nurseries, stores that sell seeds and bulbs.

It's perfect as a side dish for any meal. I grow my own so I was looking for new ideas and like yourself I highly recommend trying to grow your own (As a guide: https://www.gardenate.com/plant/Asparagus?zone=2 or https://gardenerland.com/edible/vegetables/growing-asparagus/ ). It does taste better than the shop bought plants.

Mine are 5 years old and I put compost and rooster booster on mine in late August after trimming back old growth. I pick for about 10 weeks, let the ferns grow until mid Jan and cut back again. Compost and rooster booster again and pick for 4 weeks. Then let it go ferns again. Mainly have it on toast for breaky.

Asparagus requires good friable free draining soil and full sun. Plant it out when it is 12-15

Hi Sir, firstly I live in Memel 98km East from Harry Smith and my asparagus does very well. I feel if you speak to the owner of the nursery next to the Spar he might be able to assist with plants. I have some 40 plants in my garden, all started from 4 plants. Enjoy your rewarding plants. They love the cold weather. And also seed well once they establish themselves. DO NOT BE IN A HURRY. Plant them away from the traffic even as an unusual garden separator. Do remember the bush can grow up to 1Meter high and some what wide. When it dies down leave it standing to almost the end of winter then cut them off and use for your compost. Enjoy the new venture. You are welcome to contact me.
