How to fertilize California Coneflower

Most potting soils come with ample nutrients which plants use to produce new growth.
By the time your plant has depleted the nutrients in its soil it’s likely grown enough to need a larger pot anyway.
To replenish this plant's nutrients, repot your California Coneflower after it doubles in size or once a year—whichever comes first.

Is that powdery mildew on it? #BlackEyedSusan

🎶 Happy birthday to me! 🎶 Technically it’s a couple if days early, but my plant arrived today! 🥳 I had my mini rose on my apartment patio for the last five years, but decided a couple of months ago to plant her in the ground at my parents’ place. (Side note: best decision ever! She’s flourishing like she hasn’t in years!) I’m trying a small variety of Black Eyed Susan, both to enjoy the blooms, and hopefully to help feed the local finches! #PlantsMakePeopleHappy #OutdoorGrowing #PatioGarden

I just bought this plant at Home Depot a couple days ago and now it looks like it’s wilting 🙁 I have it placed right outside my front door. My house is south facing and do get a lot of light throughout the day. I just put some water and brought it inside. I’m thinking maybe the sun is too much? Please help 🙏 #NewPlantMom #BlackEyedSusan

Hi everyone! I'm completely new to the plant world, just bought a bunch yesterday. This morning my black eyed Susan was looking fine, perky and healthy. But hours later, droopy and sad! Anyone know why? Did I over water it, does it not like the hot humid weather? I watered yesterday but not today, and it's been mid 80sF.

Will my plant ever bloom? Back in march, My mom and I were at five below, and I stumbled upon those cheap little grow kits. The brand of the grow kits was Buzzy. We bought coneflower grow kits. One for me and one for Little sis. We bought them because each year on March 12th we celebrate “Plant-A-Flower day” by planting seeds. So on March 12th we planted those coneflowers. I don’t remember this super clearly, but we’ve tried those grow kits before and they didn’t work, therefore my mom was hesitant that they wouldn’t grow, but they were like a dollar at five below. Welp, they sprouted after three-four weeks! Fast forward to now, they haven’t even bloomed , and some seeds are still sprouting now. I mean, it did take a month for them to sprout, so maybe it will take a long time for them to bloom, but it’s but THREE months. I’m starting to think they won’t bloom by autumn, and then they will just die by the cold. Before the Greg app, We only watered the every two weeks, so the Greg app will definitely help, but do you have any suggestions on how to get them to bloom? #coneflower #growkits
