Plant like a pro! Our Starter Soil Kit has the same soil that we use at Rocky Knoll Farm. Our special soil mix uses a base of select northwest fir bark, high-grade time release fertilizer that lasts up to a year, and nutrients that can help your plant thrive. This is the perfect blend of acidic, well-draining components for your new plant. We wanted to make it as easy as possible to use so it is already blended together for you; no fussing with combining separate ingredients. All you need to do is use it when you plant! One kit is good for a 1-gallon plant. This starter kit is perfect for helping to make the planting process a breeze.
