How to fertilize Earth Apple

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 Earth Apple after it doubles in size or once a year—whichever comes first.

My sunflower seedlings are turning yellow? Is this wilting? The leaves are becoming a dull yellow, although it’s hard to see in photos. They shouldn’t have been over watered or under watered? Any suggestions #help #SunFlowerBabies #Sunflower #sickplant #TipsandTricks

I don’t know what to do! :( I recently bought these Sunflowers and they started dying on me, although there are a few still blooming. What should I do? :( #Dyingplant

Why does the app say my sunflower is 88% grown if it isn’t even blooming?
-
My plant has been losing its leaves and I’m worried, the mini one is practically dead. Should I repot and try and save it? It seems unlikely because it’s two leaves are nearly gone. Please help

Friends or Enemies? Not sure if these guys are helpful or not. Anyone know? Should I leave them bee or terminate? #gardening #helpfromnature #helpneeded #planthelp

New growth! These sunflower seeds just keep growing! I’m so excited to see them get taller and taller. At what point should I separate them? #SunflowerJourney #Sunflower #sunflowerseeds #NewGrowth

So, since I didn’t have plant food, I tried another way to get the sunflower to survive, filled up my jar with some water added some sugar couple drops of bleach and sugar and so far my plants have been surviving and doing well

Shriveled leaves Hey! I have a common sunflower, and I’m new to caring for plants. Very very new haha. I accidentally left my sunflower at home, so it wasn’t with me for a month, but I had someone else taking care of it. I finally picked it up today and she’s growing great I grew her from seedlings, but she has some brown shriveled leaves at the end, how could I get her healthy again?

really happy with myself because i’ve never grown anything from a seed before🌻 #NewGrowth #dwarfsunflower #NewPlantMom #SproutingSeeds #fromseed

Heyyy everyone! I’m wondering how I can shut off watering notifications and everything during winter time for my sunflowers on this app. They’re outside, so they’re dead until next year. Any advice is appreciated! ☺️🌼💚 #CommonSunflower
Earth Apple is generally considered an easy-to-care-for plant and makes a great choice for beginners!
💦 Water Needs
Earth Apple prefers for the soil to dry out between waterings and should be watered regularly. Use our water calculator to personalize watering recommendations to your environment or download Greg for more advanced recommendations for all of your plants.
☀️ Sunlight Needs
Earth Apple requires abundant, bright and direct light. Place it less than one foot from a window to ensure it receives enough light to survive 💪. Select your region to see how the current weather in your area affects the placement in your home 🏡.
🐶 🐈 👶 Toxicity
Greg does not have confirmed data on this plant’s toxicity. If you, a family member, or a pet consumes plant material of unknown toxicity, it’s always best to consult a medical professional.
If you or someone else ingested this plant, call Poison Control at US (800) 222-1222. If a pet consumed this plant, contact your veterinarian or the ASPCA at US (888) 426-4435.
💨 Humidity
Earth Apple doesn’t require additional humidity. Plants absorb most water through their root system rather than their leaves, so the best way to provide humidity for your plants is through watering the soil.
🪴 Soil
Earth Apple does best in well-draining soil. A good soil will contain lots of organic matter such as coco coir as well as perlite or vermiculite to help with drainage. Adding a handful of perlite to regular store-bought potting soil should do the trick!
💩 Fertilizer
Earth Apple should be repotted after it doubles in size or once a year, whichever comes first. Fresh potting soil has all the nutrients your plant needs, so as long as it’s refreshed yearly, you shouldn’t need to use fertilizer. Remember, plants get their energy from sunlight, not fertilizer!
🌎 Native Region
Earth Apple is native to the Americas.
⬆️ ⬇️ Growth Pattern
Earth Apple grows vertically and new growth will emerge from the top of the plant.
🌦️ Growing Outdoors
USDA Hardiness Zone

🧐 Troubleshooting
When troubleshooting a sad-looking houseplant, start by checking for signs of distress in its leaves, such as yellowing, browning, or drooping, which can indicate overwatering or nutrient deficiencies.
Inspect the soil moisture; too dry or too wet soil can cause problems.
Ensure the plant is getting the right amount of light, as too much or too little can stress it.
Finally, consider environmental factors like temperature and humidity, and adjust care routines accordingly to revive your plant.
