Speed-Gro is a Fertilizer that helps by speeding crop growth. It can be crafted or purchased from Pierre's for 
100g. Twenty Speed-Gro is the reward for completing the 
Spring Crops Bundle in the Pantry.
Speed-Gro can be placed on tilled soil before or after planting a seed, or at any stage of crop growth. However, as of v1.2, it has no effect unless applied before planting a seed.
Speed-Gro Cost
Crafting Speed-Gro used to be cheaper than purchasing it, but that is no longer the case (it now costs 100g instead of 500g). The table below compares the cost of crafting Speed-Gro against purchasing it at Pierre's. The cost of crafting is the sell price of the constituent ingredients.
