Where are my arrangements grown?
Our plants spend their early days in greenhouses throughout the United States. Then each plant is matched to a front door in a growing location where it will thrive.
How big does my planter need to be?
The planter should be at least 14” in diameter, and ideally no more than 16” in diameter.
How do I care for my plants?
- Plant the combinations the day you receive them, and give the plants a thorough watering.
- When the top inch of soil feels dry or the plants begin to wilt, water them again.
- Feed the plants with Miracle-Gro® plant food after about 4 weeks.
Note that plant care will vary from shipment to shipment. The plant care card that comes with your delivery has all the answers.
Do I need soil for the planter?
Depending on the planter you use, you may need to fill it with enough potting soil so your new plants sit comfortably just beneath the rim. We recommend using Miracle-Gro® Potting Mix.
How do I plant my arrangements?
The plants arrive already arranged, in a tray with soil. Press the tray into the soil at the top of the planter to make an indentation. Lift out and recycle the plastic tray and nestle the arrangement into the planter. Repeat with the other tray and planter. Water the plants as directed.
If my plants arrive and they look a little tired after their trip, what should I do?
We recommend that you take a photo, then plant and water them as directed. Let them get used to their new surroundings for 5 days. If they don’t perk up, take another photo and get in touch with us. We’ll make sure you’re happy.
How do I know how much to water my plant?
Once the arrangements are in your planter, soak them with water. Soak them again when any of the plants begin to wilt or when the soil feels dry. Poking your finger one inch into the soil in a few places around the plants will help you know when it’s time.
What comes with a Knock! Knock! box?
We provide two plant trays curated by our experts. Please note that your plants will not ship at full size. This allows for the plants reach to your door safely and ready to flourish.
You will need two planters 14-16” in diameter, potting mix to plant the trays, and plant food to keep your plants strong. We recommend Miracle Gro® Potting Mix and Miracle Gro® Plant Food for the best results.
How will my plants fare in hot weather?
Don't sweat this one! Our experts know the weather in your ZIP code. They make sure your arrangements only include plants that thrive in your climate. Just keep an eye on temps that are higher than normal. If your weather forecaster makes a fuss about the heat then know that your arrangements may wilt and need water more frequently.
What arrangements does Knock! Knock! offer for winter in northern parts of the country?
We're more cuddle-up-by-the-cozy-fire types, so at this time we don't offer potted arrangements during the cold of winter.
What possible lighting conditions exist? Why is my plant supposed to have this lighting type?
Just like their climate preferences, different plants thrive with different amounts of sun. Give them too much or not enough and you might end up with leaves that are scorched and crispy, growth that is stretched and thin, or fewer flowers than expected.
If your plants are partial to "Full Shade," that means they only like 3-4 hours of direct sunlight each day, and, not to get picky about it, but preferably morning sunlight.
Plants that like "Partial Sun" thrive when they get 4-6 hours of direct sun each day.
And those that want "Full Sun" will be happiest with 6 or more hours of direct sunlight each day.

How do we pick specific plants to be tested?
Our experts are true botany nerds who make sure your plants aren't just beautiful on the outside, but that they have unique, sturdy genetics so they're super-easy to take care of once they get to your door. These experts are matchmakers, too. When they create your arrangement, in addition to style they're choosing plants with growth rates and bloom timing that complement each other.
How do you come up with the perfect arrangements for my home/area?
That's what our experts are for! They know everything there is to know about the climate and lighting that will make each plant happy. That's how they determine what arrangements will do best in every part of the country.
Why do my plants not ship fully grown?
Our arrangements aren't just centerpieces at your cousin's wedding that you can sneak out the door and enjoy for a day or two. We want them to have a long and fabulous life outside your door, so we time the growth and shipping of each arrangement so it reaches its peak growth stage right after you receive it.
How do I use plant food with my plants?
We'll make this easy. Two weeks after you move your plants into containers, apply a liquid flowering or all-purpose fertilizer every week, as described in the label. Be sure to check the care card that came with your arrangements.
What is dead-heading/why would I do it? How do I know if I should?
Dead-heading is the name for snipping, cutting, or removing flowers that have already bloomed and are starting to individually decline. Dead-heading is a common practice for many flowering plants, as it not only makes the plant look cleaner but also encourages the plant to divert its energy to making more flowers instead of producing a seed head. Refer to your specialized care card for instructions on how to dead-head and if it's a method that you should employ on your plants.
How does light affect my plants?
Your plants are at their best with the right amount of light! You'll notice rich colors in the leaves and flowers, plenty of blooms, and a full-looking appearance.
How do I know if my plant hasn't gotten enough light?
If your plant isn't getting the light it needs, you'll see the signs. It may begin to stretch, fall over, and just look a bit scraggly. It may also have fewer flowers than normal.
How do I know if my plant has gotten too much light?
Just like our bodies, too much sunlight may cause your plant to burn too. Its leaves and petals may look scorched, brown on the edges, and crispy to the touch.
What does my plant look like with the right amount of water?
Watered just right, your plant will look pert and full, not droopy or wilting.
How do I know if my plant hasn't gotten enough water?
Your plant will let you know if it's thirsty. It will likely produce fewer flowers, and begin to wilt. If it's dried out too long, sections may shrivel up and die.
How do I know if my plant has gotten too much water?
If there's too much water in your plant — from over-watering or an inability to drain out of the pot, your plant's leaves may turn yellow. It could also cause the roots of the plant to rot.
