Lavender Leaves Turning Purple And Brown

Question

Hello, I need some help with my lavender plants I purchased in mid June. I bought 1 Bridgett Chloe, 2 Provence, 1 Grosso and a yarrow. My yarrow appeared to have died but I still planted it and it has come back. I believe the Bridget Chloe has died but I’m letting it alone to see what happens. My grosso’s leaves are turning pale purple. The Provence seems to be doing well. So I was told by internet sources to use cactus and citrus potting soil because it drains well. I also planted them in 12” terracotta pots. I initially watered them when planting but have let the skies do the rest of the watering. I am concerned about the grosso right now. Is it dying?

Answer 1

I suspect they need more water. Once they are established, you can hold back on watering if it rains regularly. Since you are using well draining soil, it won't hurt to water them often to get them going. Because you have them in large pots where the volume of soil is more than they need, just water right around the plant, you don't need to get all the soil wet, or it could stay damp too long and cause problems. Containerized plants do need more water than plants in the ground, especially during the summer, so water as soon as the soil feels dry to the touch. Here is more:
