Have been away and have come home and asparagus is already up, do I cut if and start again or just harvest what comes up?

You can cut all the shoots/fern off. Any that are just spears you can eat. Cut them off each day or two. Enjoy!!!!!

I planted a few asparagus plants in a small raised bed. The bed now looks very full. What do I do for over crowding?

Thin out weaker plants and provide adequate spacing between the remaining ones. You can also transplant or divide the crowns.

I bought a punnet of very fine spindly asparagus plants a few days ago from Bunnings not much information on how to plant should they be planted individually or should I leave them in a clump? Theres about 2 dozen measuring 3 to 6 inches in height and should they be planted in a separate piece of ground or tub?

You could plant out but you would have to pay a lot of attention to them. Work out how many plants you want to grow - 6-8-10. Maybe plant two seedlings together and later (3-4mths) reduce to one plant. OR plant into pots and grow them to about ,5m and then plant in the ground. Plant in a separate part of the garden as you will have them for 20 years. The ferns grow to 1.2-1.5m high.

Want to start my asparagus bed this Fall. When is best time? Are there different instructions than for Spring planting?

I have a single shoot growing from 2 plants that are 12–14in tall already in middle of May. Should I cut these down now?

Let them grow for the first 2-3 years.

It might be slugs or snails, try using something to kill or deter them.
