Help: Is this root rot on my Lavender

9 years ago

Hi. I just planted a bunch of Lavender Hitcote on a steep slope that gets full sun. We just had a heat wave (well for here, around 90 degrees) and the plants are young and with a lot of other plants....so I watered almost daily for a about a week! ouch. Suddenly I noticed that a few of the Lavender started turing yellow. I'm afraid it's root rot. Is there any way to reverse this? They seem otherwise healthy and upright. Should I destroy them? If so can I plant new ones in the same spot? (I have the whole slope covered with mesh to prevent sliding so I have to cut holes for the plants). Any help? See pic above:) thanks

It's impossible to tell if the lavenders have root rot if we can't see the roots. But if they had I would expect them to wilt and they haven't. They look fine to me apart from a few pale leaves. I would certainly not destroy them for that. They are newly planted and have undergone a severe baking - not surprising they are a bit pale. I'd leave them alone and see how they get on.

Patience Grasshopper. Don't overwater them in response.

Ditto what wantonamara said. Next, don't panic. Lavender needs full sun but requires dry to average soil (see link). Planted in healthy soil on a steep slope they should have sufficiently adequate drainage to thrive with minimal help.

and never expect all of many to survive ... expect some ratio of failure ...

could you favor us with a pic of the whole .. i have never seen nor heard of the netting ... sounds interesting ..

BTW .... dig up one of them.. AND FIND OUT HOW WET OR DRY THE SOIL IS .... and adjust watering accordingly ...

if you are just guessing with your watering.. obviously.. you are frustrated because you lack info ... but coming to us for info ... gets you no where.. but more guesses... so all you are left with.. is digging some holes and finding out .. and mind you .. dealing with a hill ...and how water moves across and thru it.. can be divergent in differing spots ... and that may be why.. those struggling.. are not all in one place.. leading you to dig more holes ...

you might want to dig out all those struggling.. and set up a nursery bed with some break in the blistering sun ...... and see if you cant rescue them.. by fall ... then.. you have a whole bunch of holes all set for observation ...

i SUSPECT ... you have been incredible successful ... perhaps even better than many of us might do ... but are a perfectionist at heart.. and its driving you a bit crazy ... that yoru success is not 100% ... heck.. most gardeners ... dealing with the vagaries of mother nature.. would probably be thrilled.. with a 90% success rate and would just replant the holes in fall [NOT NOW] ... and if that is the case.. the problem is in your head... LOL ...

BTW.. in fall ... you can harvest some of the plants on any edge.. and put them into the bare spots... to make the 'look' equal ... and then add replacements at the edge..

or even better.. DIVERSIFY your planting ...

good luck

pic of the whole.. please
