They don't seem to be growing any new stalks or very many leaves. Will they recover, or do I just need to replant? I'm stumped. Over the course of two years I planted 7 or 8 various echinacea. They came up, flourished and even self seeded for a year or two and then, for no apparent reason, two years ago not a single plant came up. A few of these were pretty healthy, large specimens. The care they received was always consistent and I never use herbicides or insecticides near them. Have UFO's invaded my garden and carried them away?
I have a 30 x 60 greenhouse. I purchased a tray of echinacea plugs from a reputable company, and they were beautiful.

I did fertilize my entire greenhouse with miracle grow liqua fertilizer with an injector a week ago. It is very warm in the ghse when the sun is shining.
Today I notice that the leaves on the plants are turning brown and crisping. The centers of the plants look fine. Too wet? Too hot? Or too much salt in my well water? Nothing else in the ghse is affected like they are.. Your article states that coneflowers are deer resistant. The deer here in Connecticut must not know that because the love the new buds!
I bought echinacea transplants in the spring and planted them in large pots, along with a tomato and a zucchini. After my neighbor sprayed Roundup in his yard I didn't get any female blossoms on zucchini and cucumbers. My strawberries and tomatoes stopped producing. Strawberry leaves still look healthy, but tomatoes leaves are slowly dying. Now, months later I'm thinking the echinacea was affected because there are no blooms, just healthy looking leaves.
Do you think the echinacea and strawberry plants will be ok, and safe to ingest if they come back next year? Or, do I have to pull entire plants? A University of California expert suggests this: Round Up can linger for a while, maybe even longer than a month especially in a sandy soil in which it is not adsorbed to fine soil particles as it would in a clay.
The solution to this predicament, and indeed in all cases of Round Up toxicity, is to let the plant grow out of it. Planted an orange coneflower this year.

Purple coneflower Echinacea purpurea is a popular perennial in Zones Pruning: Though deadheading is a common garden practice to encourage repeat blooming, many varieties these days are flower machines and will keep producing without snipping off spent blooms. That way you can leave them be, guaranteeing food for another beloved category of wildlife—birds, particularly small songbirds like goldfinches, which are crazy about the seeds.
Flowers appearing post-deadheading can be smaller and less satisfying, so why not just leave the first, bigger flowers to go to seed and give the birds a feast? Once your coneflower has finished blooming, it can be cut down to ground level to over-winter. Or, if you prefer to leave the dried seed heads, it can be cut down in early spring.
