There are some common varieties that are recommended for North Texas. Lavandula x intermedia ‘Provence,’ L. x intermedia ‘Grosso,’ L. angustifolia ‘Blue Cushion,’ and L. angustifolia ‘Vera.’ All are hardy varieties and provide good flowers and plenty of essential oil.
Lavender will adjust to different types of soil over time.
Plant on raised mounds to drain away water. Don’t plant in low places that may collect water. Lavender likes to be dry and needs little water once established.
Water once or twice a week the first year if no rainfall. Water down to the roots. Sprinklers may encourage fungal disease.
You don’t really need mulch, due to lavender preferring to be dry. Mulch may also encourage fungal issues. Also, remember not to plant too close together for the same reason.
Key points with lavender are full sun, excellent drainage and good air circulation.
Once established, water during times of drought, especially prior to blooming, to help promote flowering and improve oil yield.
Trim plants back lightly just after blooming. Cut back by 1/3 to 1/2 in early spring to promote new, vigorous growth and encourage blooms.
Enjoy that lavender.
