How to fertilize Anise-Hyssop

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 Anise-Hyssop after it doubles in size or once a year—whichever comes first.

Hyssop, a true bed & breakfast...if you're a bumblebee. My evening routine now includes a few checks of the anise hyssop to coo over my guests. As a kid I found it so annoying to discover my mother had taken pictures of me sleeping. I finally (sort of) get it. Busy tonight. Several bees were bunking together. 🐝🐝🍃 Wishing you and your pollinators sweet dreams 💤 (Can you find all seven sleeping bees in the second photo?) #plantsmakepeoplehappy #happyplants #happybeesyesplease #bumble #pollinators #hyssop #bluegianthyssop #anisehyssop #agastache #scentedblooms #outdoorgrowing #sweetdreamsaremadeofthis #crowsfollowmeirl 20230905

Sleeping Bee(auty) 🐝💖 The Anise Hyssop in my garden is popular with the pollinators. The bees in particular find the flowers not just delicious but the perfect place to sleep. They lock their mandibles on to a petal and drift off... I've never seen so many sleeping bees as I have in the last couple of weeks. Bees experience the same sleep cycles as we do. The one I was watching tonight was definitely dreaming...and last night, this sleeping sweetheart was in deep sleep; he was right where I left him an hour after I first spotted him. #plantsmakepeoplehappy #happyplants #happybeesyesplease #pollinators #crowsfollowmeirl #hyssop #anisehyssop #agastache 20230817 #sweetdreamsaremadeofthis P.S.

#latenightrepot When the mood strikes, sometimes you just gotta go for it. No matter the time or lack of sunlight. I finally repotted my second #anisehyssop I swear she looked like she was stretching her legs, breathing deeper and filling out her new home within minutes of moving in. Pretty amazing, really! Wherever you are; whatever time it is there, wishing you sweet dreams. Today didn't go so well? We get another chance to try again, tomorrow. 🙏🐝🍃 #plantsmakepeoplehappy #happyplants #happybeesyesplease #pollinators #hyssop #bluegianthyssop #agastache #scentedblooms #outdoorgrowing #sweetdreamsaremadeofthis #cococoir #happyworms #vermicompost #crowsfollowmeirl 20230924
Anise-Hyssop is generally considered an easy-to-care-for plant and makes a great choice for beginners!
💦 Water Needs
Anise-Hyssop 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
Anise-Hyssop 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.
🪴 Soil
Anise-Hyssop 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
Anise-Hyssop 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!
⬆️ ⬇️ Growth Pattern
Anise-Hyssop grows vertically and new growth will emerge from the top of the plant.
🌦️ Growing Outdoors
USDA Hardiness Zone
Anise-Hyssop can be grown outdoors in USDA Hardiness Zones 5a-9b. Find your local hardiness zone here.
🌱 Propagation
Anise-Hyssop can be propagated by division into new individual plants.
- Check to see if there is more than one plant. In some cases they may still be beneath the soil surface. If you feel confident, you may remove the soil to check for baby plantlets below!
- If there are multiple plants growing, unpot the plant and gently tug the plants apart, being careful not to disturb too many of the roots. They may be connected by large root segments which you may need to break to free the plantlet.
- Pot up the new plant in well-draining soil
- Repot the parent plant back into its original pot
🧐 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.
