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.

When is the best time to split crowns and replant?

In the winter while they are dormant.

I've bought purple asparagus in a pot. There are 6 woody stems in the pot. Should I try to disentangle the root systems and plant each stem separately ?

Yes. Detangle the roots and plant separately.

We actually live in Sierra Leone. We have had our plants for several years. We keep watering them through dry season (Mid Nov-April) so they won't die. Will they die if left alone or just hibernate? Also, should we trim fronds off at all or bend them over to reseed (they have multiplied on their own fairly well). And when should we add compost?

I cut my ferns off late winter (August), apply compost and fertilise and water well. I pick all spears until the end of Oct (2 mths) then I let the ferns grow. I water each week. I do another picking in Feb for 3-4 weeks. Then I let grow again. I water until end of Autumn. Then let the ferns die back. Cut off end of winter. I cut my ferns off water really well. apply 100-150mm of compost and fertilise and water well. Spears usually start shooting straight away (early Sept). I live Sub-tropical Australia.

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