I also have new rhubarb. Two plants. I only got two sticks of rhubarb on each. Is this normal for the first year. Should the crowns be under the soil or above.
Perfectly normal - you shouldn't take a crop from rhubarb in it's first year - water it well, mulch around it with farm yard manure - hopefully it will grow more stalks this year but as I said, leave them to die down on the plant.
Next year you can take a light crop from them, but I wouldn't pick after June to allow the crown to build up.
Crowns should be poking through the soil.
I would buy and plant rhubarb in the late autumn or early spring, just as the plant is begining to come out of winter dormancy.
