Hi, Terri.

Do you have gutters, or does the rain run off the roof into the bed with the lavender? I am guessing the lavender are getting too wet, even with your sandy soil.

I had a lavender survive 2011 when we had 100 days of 100+degrees that summer and less than 4" rain from January through August. But I lost that lavender in a wet winter. I now only grow lavender in a raised bed, and I amend the hole with grit (and I have sandy soil too). Four lavender plants survived last May when we had 17" rain in this bed and look great now. I just don't think it's heat, more likely too wet for them.

You could take the lavender out of the bed and pot them up for now, until you decide.

I tried several years with those plants from Lowes and HD. Every year, they would last for a few months and inevitably dry up. The ironic thing is that the plants around them would be fine, with the same watering and hot temperatures.

So now, just like fuschia, I have given up on lavender as being able to grow here in my area....or at the least, in my garden.

I've got mine in a raised bed in a shady spot and it seems to be thriving. It only gets morning sun. I agree with the comments above - it might be getting waterlogged.

water is it's worst enemy mine are in pots (from lowes too) and are about 4 months old and i have never watered one of them on rain has watered them... they're looking pretty good....better if i keep them deadheaded i did repot them using rose soil and cactus soil

I'm in Austin and planted them in a bed which got late morning/afternoon sun, and once the hot temps were upon us, even with regular watering, I was unsuccessful. I tried relocating them to a shady area, but alas, they were too far gone, and bit the dust! Coming from Ca, where it grew almost wild, i'm so disappointed I can't get it to grow here. I haven't tried containers, but might give it a shot,setting them under the Crepe Myrtles.

Chappell Hill Lavender Farm in Brenham had to replant all of their lavender fields due to last spring's heavy rainfall. Their fields are planted in full sun, so I don't think heat is a factor for lavender. The only time I water lavender is in July, August, and early September when we haven't had rain, and then it's only twice a month. In 2014 when we were restricted from watering, they only had rainfall and looked a bit tired in August but were fine. Too much water will cause lavender to rot and once it starts to rot, nothing you do can reverse its decline. As long as they have good drainage, lavenders thrive on neglect.
