Growing Instructions

Plant Oxalis Triangularis in the spring after the danger of all frost has passed. Soil preparation: The ideal soil is porous and drains well and yet still holds enough water for the roots. If your soil is heavy clay and drains slowly, or very sandy and does not hold water, add organic soil amendments (peat moss or ground bark). Spread a 3-4" layer of soil amendment, add fertilizer and incorporate together into the soil to a depth of 10". To plant: Dig a hole 1-2" deep. Place the roots in the hole so that the tops of the plants sit 1-2" below the surface. Space the plants 10-15" apart. Water thoroughly after planting. While actively growing, water frequently and thoroughly so that the water will reach the roots. Mulch to keep the soil cool and to prevent the soil from drying out. 

Care Tip

Apply fertilizer before and after flowering.
