According to SF Gate, a gardener planting Texas sage needs to choose a good location, make sure the soil is at the correct moisture level and use soil that contains the proper mixture of nutrients and additives. Texas sage is grown either from seeds or from a cutting.
The first thing a gardener needs to consider when planting Texas sage is where to plant it. This plant needs plenty of sun, from four to six hours each day. The next step is to make sure that the soil is moist when planting a seed, which helps it to germinate. The gardener then needs to gently press the seed into the soil, but not bury it. If planting a cutting instead of a seed, it needs soil that is half peat moss and half perlite. Normally this plant does not need rich soil in order to grow, and it thrives in rocky and gravelly soil that drains well.
After the planting stage, Texas sage needs to be cared for properly. It is a low-maintenance plant that requires little water in most seasons and typically needs none at all during the winter. In fact, over-watering it can kill blooms and cause root rot.
