At Soil Sunrise, we hand-blend each soil mixture to ensure you get quality every single time. Olive trees like extremely well-draining, rocky soil. It’s best to plant your tree in a mix of potting soil and perlite or small rocks or pebbles. Our blend is a mix of peat moss, perlite, pumice, and lime - making it the perfect combination for the healthy growing of olive trees. This blend is ideal for indoor or outdoor use for container gardening. TIP: With proper olive tree care, it is best to begin fertilizing in March, using a high-nitrogen fertilizer. Continue to fertilize your olive trees throughout the growing season. Never use wood chips for mulch as they rob the soil of precious nitrogen. Instead use pine straw and keep the straw away from the trunk by several inches. INGREDIENTS: peat moss, perlite, pumice, and lime.
