I cut her and opened up some of the stems, the main stem as welI. I have seen lot of caterpillar damage (hollow stems) and some branches had some grey parts inside.
I also digged her out. l. Huge rootball and the roots didn’t look rotten.
I am still not convinced it is fusarium.
I appreciate any comments on it.
Update:
A lesson I learned in this round:
-use trichoderma in the beginning so fungal pathogens have less chance to mess your garden up
-use neem (adding it to your compost or spraying diluted on the plants REGULARLY)
-desinfect your scissors before you touch your plants with them
-try to catch butterflies (moths) at spring when they show up and start to use BT even before once every 2 weeks
-use of horsetail extract as fungicide.
Anything you would suggest as Pest Prevention?
@birdmountain, if is caterpillars then BT is the thing to do. If you’re in Canada it’s widely available at places like Canadian Tire. If fusarium I don’t know but removing the affected are is likely the best option.
@birdmountain, probably it is as @Lerome pointed it out to me. Now the question is how to get rid of it: cutting only the plant that is clearly affected by it or cutting all the 3 in the same flowerbed…
