How it works

Plant Starter nurtures plant growth both above and below the ground - it feeds both the soil and the plant. It includes:

  • Original Scotts Osmocote® controlled release fertiliser granules that release nutrients when plants need them most for up to 6 months. It gives your plants the nutrients they need, just when they need them. Less in Winter and more in active growing periods
  • Bio stimulants to encourage microbial activity and organically enrich the soil
  • Composted manure, blood & bone, seaweed and fish that organically enrich the soil and encourage beneficial microbial and earthworm activity
  • Natural gypsum, a clay breaker that improves the soil and adds calcium
  • An excellent wetting agent that enhances water absorption into the soil and helps plants take up more nutrients

As a result, plants are healthier and less susceptible to insect attacks and disease
