4 marksWhen filling a sack garden, a column of stones is placed in the middle.
(a) State the purpose of this column of stones.
(b) Explain what would happen to the plants if the column were left out.
(4 marks)

(a) 2 marks: the stone column allows water poured on top to drain down and spread to all the plants, including those planted low on the sides. (b) 2 marks: without the column, water would not reach the lower and inner plants evenly, the soil could become waterlogged at the top, and the plants at the bottom would dry out and grow poorly or die.

A. To make the soil hard and firm

(4 marks)
Marking scheme
Any two, 2 marks each: it uses very little space yet many plants can be grown, so it is good where land is small; it is easy to water and to take care of the plants in one place; it can be placed near the house/kitchen for convenience; it uses less water because water drains through the central column to all plants; it can be moved or made using cheap, available materials.
