Burying Blackberry Crown?
I planted a ton of blackberry plants last year. I planted them so that the crown was at the original soil surface level.
However, the soil around a couple of the plants, and the plants themselves, have sunk so that the plants and soil immediately around them are below the surface level of the ground.
Can I add soil, slightly bury the crowns in dirt, to get the plants level with the ground again? Is there any harm to a semi-erect blackberry plant (like Chester or Triple Crown) in partially burying the crown deeper than it has been growing?
