I was told never to trim the ferny bits as they harness strength for the crown & help develop bigger & better spears for the following season. Is this incorrect. I bought crowns from K-Mart over 15 years ago. Had them in a small pot. They grew, they 'died', they grew again & died again. I decided to transplant them into a large garbage bin, about 75cm deep. They grew & produced lovely tasting, about 3/4 cm thick spears, over the last two years. I've fed very randomly (haven't been well for long while) sometimes Dynamic Lifter, sometimes Seasol, sometimes Complete Fertilizer. I don't think I've even fed them once a year!!! I'm trying to show them some loving respect now, & so shocked at how they tolerated gross neglect & still gave me precious, delicious spears to just pick & eat...never made it to the kitchen!!

Is it possible to grow asparagus in pots? I am currently renting so unable to plant in the ground.

You probably would need a pot about 700-900mm diameter and 600mm+ deep - maybe deeper. Mighty heavy to move when full of soil. It take 2-3 yrs before picking a decent amount. The supermarket maybe a better option. =

Can you spray for weeds around the asparagus in winter?

Three suggestions 1. Straight after you cut all the dead ferns off in winter spray the weeds - not recommended really you could kill the plants. 2. Give the ground a watering and pull the weeds out by hand - recommended. 3. Don't let the weeds grow much pull them out as they germinate. At the moment I have dozens of tomato seeds germinating from the mulch/compost I just put on my asparagus.

I have bought tiny ferns of asparagus,2-3inches high, which i'm about to plant. i'm not sure what the different terms mean or look like? ie roots shoots ferns crowns . in what sequence do they grow and when.

After 6 months or so your little ferns will have a hard bulb - that is the crown - this will grow bigger. Next time you go to Bunnings look for asparagus bulbs - about 9 mnths old. From the crown you will have roots - just like any plant has. After you have trimmed off your asparagus plants in the winter and it warms up, shoots come out of the ground - these are called spears - these are the things you cut off and eat. If these are left to grow then they become ferns. GO on the internet and type in growing asparagus and read read,

What varieties of asparagus will do well in zone 8a? I live West of Fort Worth, Texas I wish to buy 2 year old or older “Crowns”.

i have cut back my asparagus when it died back, about 3 weeks ago. I covered it with manure and compost and it has begun to grow again. The new stalks are about 15 - 20 cms already but only pencil thin. I really want to harvest white asparagus, should i mound the soil up over the asparagus now? or should i let it just grow?
