--answer for 250 sq feet--Garden--

Hi Invincible,

For 250 sq feet of garden you may use the following amounts:

Ground Limestone(Calacitic), which is Limestone which is high in Calcium--12#-24#

Ground Granite or rock of similar make up--6#-12#

Ground gypsum---3#-6#

Bone meal--3#-6#

Best to mix these together before time and then spread them on the ground and work in to top soil !


But "IF" you are going to container garden then you want this amount then mixed with the same total amount of soil, so that you have a much more concentrated soil to grow more in a smaller space!

Smile Tis your choice. Tweet
