Snowlogging

"Snowlogging" is a mechanic in Bedrock Edition that allows layers of snow to occupy the same block space as certain types of vegetation.

Snowloggable plants can be buried in snow that is multiple layers.

Process
The following methods can create snowlogged plants:
 * Placing snow where a plant is.
 * Snow forming where a plant is due to snowfall.
 * Snow falling on top of a plant.

The following methods cannot create snowlogged plants:
 * Placing a plant in an existing snow layer (this will remove the snow).
 * This is unlike waterlogging, where placing a block in water will create a waterlogged block.
 * Plants generating in snowy biomes (the plants will generate unsnowlogged even if surrounded by snow, just like in Java Edition).
 * Snow golems walking through plants (the plants will remain unsnowlogged).
 * Using commands, such as or, to place plants where snow is, or vice versa (this will eliminate the block that was previously there).

Snowloggable plants
Only 1-block-high plants are snowloggable; 2-block-high plants, such as sunflowers and tall grass, are not snowloggable. Furthermore, solid plants such as cacti are not snowloggable. Of the 1-block high, non-solid plants, flowers (including wither roses), mushrooms, grass, and ferns are snowloggable. Bamboo saplings, beetroot crops, carrot crops, dead bush, dead coral fans, melon stems, nether wart, potato crops, pumpkin stems, sapling, sea pickles, sugar cane, sweet berry bushes, and vines are not snowloggable.

Trivia

 * When snow falls onto sweet berry bushes, the snow will move downwards very slowly (since the block slows entity movement) making the bush appear snowlogged. However, the snow breaks when it eventually hits the ground.
