How close is too close in companion planting ? Thanks

Sorry I had that wrong. I was thinking non compatible plants. Companion planting would be fairly close taking into consideration what area both plant varieties need to produce a decent crop. Like if you were growing beans you would grow marigolds (I don't know if they are companion plants) about 500-600mm away. You don't want one crop over growing the other crop. Generally people plant things too close together - me included.

2-3 meters.

In north central Indiana, USA, I usually trim them back after the first frost, and add mulch through the winter. Is there anything else I can do to enhance my crop next year? Bob Koch

I have been growing for 3 years and done a bit of research. I don't have frosts. August is the end of winter here. Temps start rising from 6-10 to 12-15 by end Sept at night. Days go from 20-25 to 24-28. I cut mine 1st week of Aug and apply compost and horse manure. The manure is new but I'm going to try and decompose it before hand next year. I also apply some fertiliser once it starts to shoot spears. 3-4 teaspoons to 9l of water.

I buy my asparagus crowns from Green Harvest who are located in Queensland and sell their products, seeds and edible plants by mail order or if you live near them you can buy in person. They are an organic plant seller.

Hi, I planted an asparagus plant last year (2017) in July. Cut back the ferns in August this year (2018) and topped with compost. There are a few spears that have come through now. What should I do with them? Should I cut them back or just leave them? Thanks

Read up on the internet.

I’m in Melbourne outer east, I have 6 asparagus plants from one and two years old. Only one of the newer plants has spears coming up from about 2 weeks ago. At this stage I’m leaving them to get stronger.
