I am so thankful for your service! While I am not a wildly successful gardener, this year seems to be particularly fatal for my plants. I hope you can help. First, I have an ~8in peony I planted this year (early summer or when it was cool) that now looks like this (see attachment). I don't know if I need to give it more water or less. Or if it needs some sort of food. I gave it Biostarter and amended the soil with LeafGro when I planted it. Now it has yellowish veins and is just not thriving. None of the plants I have put in this new area in my yard are thriving except the liriope and the heuchera. More questions to come! Thanks,
Since you asked about watering: This was an abnormally cool summer and we had quite a bit of rainfall. Plants generally like about 1" of rainfall a week. They like the soil about as wet as a wrung-out sponge. We recommend that everyone have a rain gauge so they can judge how much moisture their plants are really getting--with spotty thunderstorms you have no idea otherwise.
So, water when we haven't had rain or feel the soil by sticking you finger or a tool into the soil. If the top 1/2" to 1" of soil is dry, then water.
Many plants are killed by overwatering as well as under-watering.
We can't tell from the photo, but also keep mulch off of plants. It should never be piled on the base of plants, including trees and shrubs, and kept to about 1-2" in depth.
