Coreopsis - Complete Grow and Care Guide

Coreopsis is a perennial flower native to North America. There are dozens of different species, and Lanceleaf Coreopsis (Coreopsis lanceolata) will be featured in this video. It grows best in Full Sun and Well-Draining Soil. Reaching a height of 2' (~60 cm), this flower will be extremely showy in Late Spring/Early Summer. It is a great cut flower that you can use to make bouquets or put into a vase.

[@radamaerltp]

Hello, Joe, I found your channel a few days ago and already it is one of my favorite - so informative, interesting and real. I have a question about deadheading coreopsis. How is deadheading compatible with attracting birds? Do I leave spent blooms if I want to attract birds? Can I deadhead after the birds had their fill? Should I deadhead partially: leave a few for the birds? I really loved your footage with the goldfinches. We have them around here and I like the idea of providing a natural feeder for them. At the same time, I want my coreopsis to look nice as it's in the front patch of my garden. Thank you. Your videos have inspired me to plant more native flowers.

[@growitbuildit]

Hi Tanya - regarding deadheading and seeds. You are right that deadheading will reduce the amount of birds, as you are stopping or removing seeds. That being said, you still will get birds, just not as many. In my experience, when you go deadhead you will be clipping spent flowers that just wilted, are in process of making seed, and have completely made seed, and where the birds have already been feeding. So, you should still get some birds. But - don't forget to save some seed. These plants don't always live very long. In fact I the one by my mailbox died out. But it was no problem to just move a volunteer that self seeded from the patch near the front door. Still though, I always save some seed at least every couple of years. You never know when you may want to start some. And it doesn't take much time or cost any money. Oh - and thank you so much for the kind words! I'm very happy you like my style of video. I'll try to keep them coming.

These are really easy, shorter perennials to have. They are supposedly not that long lived, but I find that they self-seed enough where you don't notice any population drop, and are actually pulling volunteers that you don't want. But if you keep up with deadheading them, they do look good most of the Summer.

Hi James - I would wait until Autumn really sets in, where just about all 'plants' are dormant and all leaves are dropping. Then just cut away anything that looks dead. If there are any green leaves, leave them.

[@growitbuildit]

Hi Tara - you may not get any flowers until the following Spring. But Blooming & Rooting from Ferti-lome is about the best at promoting blooms. Miracle grow can also work, but isn't as potent as Ferti-lome brand. Also, is it in a large pot? Larger pots will have larger root systems, that will make it easier to make blooms, grow, etc.

I successfully grew my coreopsis in a pot this year. Will it overwinter if I prune it back and bring inside to my basement?

[@growitbuildit]

Most likely yes, or just leave it in an unheated garage or shed. However, know that they only live 2-3 years, and sometimes less. So you should save some seed and try to start some in late Winter (for stratification) just in case.

What a great channel; just found it today. Question about raising from seed: is it too late to grow and transplant seedlings here in Virginia starting now in early July? Or better to wait until spring next year? I’m 80 and want to establish the micro prairie soon, if you get my drift?

[@growitbuildit]

Hi Gerry - For plants that don't need a cold treatment (see my vid on stratification) you definitely can. You could also probably start seeds that only need 30 days stratification. But you need to get started quick. As in, get seed now. If you got seeds this week and stratified them in the fridge (3-4 week), then you could probably germinate them by mid-August. Then, grow them in pots 4" or 6" diameter until Autumn. You can then just plant them in Fall or early Winter. I usually plant about 20-50 plants in November. When you go to plant your seeds - make sure it is in a location that gets morning sun/afternoon shade. It is very important now as the hot summer temps will dry things out quickly. Just water in the morning. You don't want seedlings sitting in too wet of a soil all day/night, as you can get damp-off disease. This particular variety of Coreopsis is very easy to establish quickly. But you may as well start on any of the milkweeds, etc. Also, a pack of seeds usually has 200+ seeds. So even if you didn't have success, you would still have your seeds for winter-sowing.

Most common reason for less blooms is usually less sunlight. But it could be because they are young too. Let them do a bit of self-seeding, you are bound to get some good ones.

It is packed with bees, brings in all sorts of butterflies, hummingbirds, and hummingbird moths. It is versatile and tough.

[@rowdy7011]

Trying to go native in my new, SC yard. The lanceleaf coreopsis I planted along my garage are slowly succumbing to powdery mildew. This is the 2nd year after planting. I've tried neem oil and insecticidal soap with no relief. Do these plants need excessive air flow? Is along a building not a good area for them? I read they can tolerate heat and humidity well?!

[@growitbuildit]

Hi - These plants are generally not that long lived, but I've not seen any succumb to powdery mildew. But the main thing would be to have well-draining soil, as other than that, you can't control conditions very well. In high humidity, the disease will be persistent. Even if you treat plants, spores will transfer over time as the disease is mostly everywhere. So it can transfer from other areas of your yard. The best defense is having healthy plants, and trying to make sure there is airflow. But if it is a high humidity environment, it will likely be there to some degree no matter what.

Excellent informative video. Thanks. I'm interested in planting pollinator attracter plants and this looks like a good choice. Do you ferilize these? Should I plan on cropping them to keep them in check (do they spread out like shasta daisies)? Are seeds readily available? Thanks

[@growitbuildit]

Hi Ed - Lanceleaf Coreopsis is a really good choice for attracting pollinators. One nice thing about Coreopsis is that it does not need any fertilizer. I gave mine a handful of compost when I planted them, but that was several years ago. I've done nothing since. These don't spread out too much. They will get about 6-18" diameter depending on conditions and competition. My original planting (near the house along the sidewalk) was 6 plants, spaced 6" apart. As far as cropping them, I have to trim the ones near the house as they don't get as much wind, nor sunlight from all directions. They will self-seed somewhat though, but have shallow roots. You can move volunteers around or just pull them if they are unwanted. But Lanceleaf Coreopsis is an excellent choice for pollinators as they will bring in both bees and butterflies. And you can keep them blooming right up until frost with deadheading. This year I did just that - it takes about 10 minutes to deadhead a plant, and you will need to do it every 3-4 weeks. The seeds are readily available online - here is a link to some: amzn.to/3oXb8gG I buy seeds from this company every year and always have good results. If you are looking to attract more pollinators, may I make a suggestion? Anise Hyssop is an excellent choice that would pair well with Lanceleaf Coreopsis. I will be making a video on this eventually. But I've written an article on it in the meantime - growitbuildit.com/anise-hyssop-agastache-foeniculum/. I have two large patches of this, and it is very busy with bees and butterflies. It is very easy to grow from seed too, and about the same height as the Coreopsis. But it is a very busy plant with bees and butterflies. It starts blooming in mid-Summer and goes until September/October. The purple color contrasts with the Coreopsis quite well too. Just be aware that Anise Hyssop will spread via rhizome roots. But there is a trick you can do to keep it contained. You plant it in a pot with the bottom cut out - I did do a video on that here: kzbin.info/www/bejne/eZ3OaXh-Z9yFZ6M

Since they're so prolific , do you need to keep them thinned out , and what is the spacing ?

The seeds would germinate in Spring, so you can easily remove seedlings then. They need that cold stratification, so they don't continually germiant throughout the year. They are not a long lived plant, so I usually move volunteers around each Spring to fill in gaps should I lose a plant.

Hi Susan - the root depth is around 4-6" for most of the mass. This plant isn't that long lived, but it self-seeds enough where I pull extra mature plants periodically, so the depth portion is from my memory of doing that.

Hi Mary - if you leave them up, they will feed birds during the Winter. I wouldn't divide these, as they aren't that long lived. But, you are likely to get some self-seeding in Spring, at which time you can rearrange any volunteers or replace any that may not have survived.

Does dead heading work for most flowering perrenials ?

[@growitbuildit]

Hi Benjamin - it works on many perennials and annuals. I've mainly done it on Echinacea and other 'daisy' like flowers. I think a lot of it depends on when the plant blooms. Late Summer / Fall Flowers probably can't sprout new buds and bloom in time. I'm also not sure if it would work on Lobelia, but perhaps I will try this year. Mine are just starting to bloom, which seems very early. I'll let you know. My general garden strategy is to have constant color or blooming by at least one species. That way I can keep the beneficial insects around more by helping ensure a steady supply of nectar/pollen. Because of that I haven't bothered with too much dead-heading, as I always have something cool to look at.

[@DCEventphoto]

Growit Buildit thank you so much. Are you a botanist by training ? Your site is so valuable to me

[@growitbuildit]

Hi Benjamin - I am flattered by your comment. I actually have no formal training in Botany (although I did work at a Mom&Pop garden center in High School). But, I research and read, read, read, about plants I would like to grow. When possible, I try to locate them in the wild and observe them, the conditions/settings and other plants nearby. Then I plan, and grow them if I feel they would do well in my yard. I generally grow them multiple times, so I gain a thorough understanding of their nature. I guess you could call me an extreme hobbyist. But, over the years I've gotten very skilled at germinating seeds and tending to plants. But it makes me very happy to hear that you find our site helpful. I have a large backlog of articles to write and videos to make. So, hopefully I can keep putting them out at a decent pace.

[@growitbuildit]

Hi Irina - Coreopsis aren't always long lived. I may have lost a few this year myself. It is either that or they died back due to drought. If you have them in pots I assume you watered them regularly. I had several die back to nothing this year in the drought. Although since then they have put out some new leaves. I will be scattering some seed around them this fall just in case they don't come back next year. So, if you are able to save any seed I suggest you do so. If not, perhaps buy some for sowing this Winter/Spring. If they've been dead for a couple months with no signs of life, then I would assume they are goners. But, perhaps you could still get lucky.

How does clay drain? Must be misspoke

[@growitbuildit]

Hi Abu - it can drain under certain conditions. If has plenty of organic material or good soil structure, it will drain well. Or, if it is on a slope, it can drain well too.

[@frankwerner9698]

are some variety's better for pollinators? Thanks

[@growitbuildit]

Of all the coreopsis I grow at the moment, this one seems to be the best. But I also have the most of it too.

[@kimgilbertsen8599]

I have my Coreopsis in a container it is chlorotic how do I fix it

[@growitbuildit]

If you can test the pH, then do so. If it is too high it can cause this condition. Otherwise, I would top dress around the plant with two handfuls of compost and see what happens over the coming week or two.

How do I help mine? I live in the armpit of Texas and it’s super hot, some of the stems and leaves burned in the sun, I had to put in partial sun now! How should I save mine? All the flowers are cut now too because they withered.

[@growitbuildit]

Hi Raver - The native range goes about as far South as Houston. If you have moved them to partial sun, then they are probably good. I would keep them well watered, as transplanting anything now is stressful. But I get pretty rough with my plants, and coreopsis seems to come back alright.

@@growitbuildit sadly she didn’t make it :( she had root rot! All the stems turned black, so I read up and got two more tick seeds and I put them in compost and sand and mixed with some soil and they’re doing well, just not watering as much because I know now that they can handle some drought

Good to hear. Have you ever tested your drainage before? I hadn't considered that possibility.

[@VeronicasVeil333]

I received a transplant coreopsis this spring and it was a bit floppy and spindly but produced several flowers which I deadheaded always. My question is it seems to have really grown with lots of healthy green foliage but only 5-6 flowers at a time. Is this normal for the first year?

[@growitbuildit]

Hi Patricia - if it was germinated this year, then that could be normal. The ones that you see next to my house in the video were germinated/planted in 2017. I did some digging and found a picture from 28AUG that year, and only one of the six plants was blooming at all. I just counted and there were a total of 48 buds, blooms and seed heads combined. I would say that 11 of those were 'active' blooms. So, perhaps just give it until next year. I never fertilize Coreopsis at all except for a handful of compost when I first plant them. And they look great with minimal care.

Can I plant 5 or 6 plants of coreopsis together for better looking?

[@growitbuildit]

You can do that, but one will likely dominate the others, or they will be small. Personally, I just space them about 6" (15 cm) apart which gives a larger mass.

Don’t coreopsis come in different varieties ? Do they all grow the same way ?

[@growitbuildit]

There are a dozens of different Coreopsis Species. Currently I grow 3 of them. The other two are Tall Coreopsis (Coreopsis tripteris) and Plains Coreopsis (Coreopsis tinctoria). All three are surface sown, or just under the surface for planting depth. But Plains Coreopsis needs no Cold Stratification. I've got a detailed article and short video on Plains Coreopsis. It is more of a 'wild' type flower but is pretty and will bloom from early Summer to frost. Once in a while I will have one survive the winter and come back. It is really a cool plant, and shares a lot of characteristics with Lanceleaf Coreopsis. I'll have to make a more detailed video on it later this year. But have a look - it is crazy easy to grow, save seed, and germinate. growitbuildit.com/plains-coreopsis-grow-care-guide-coreopsis-tinctoria/

Is this snail resistant

[@growitbuildit]

Hi Carol - if you live in a very humid or wet area, you could get snails and slugs on this plant. I never do, but my area isn't particularly humid.

Do you have o pinch them out when growing from seed

[@growitbuildit]

If you sow very heavily, then sure. A single plant should reach 2-3' tall by 1' in the open (from memory,)

[@poppyandpinky]

@@growitbuildit I mean pinch the top of the plant to promote growth. Sorry! Thank you for replying. Much appreciated.

[@growitbuildit]

Oh, understood. I don't think it's necessary. The only pruning I do is for plants that are sheltered on one or two sides, as they will just grow towards the sun. But I don't worry about seedlings. I think only a couple managed a bloom the first year I grew them.

[@poppyandpinky]

[@sphillips6357]

Hi, I recently bought my first couple of Coreopsis, Solanna Golden Sphere. They look like yellow Marigolds and are shorter than the Coreopsis shown in your video. I was told these will not produce viable seeds, is that true? Also they look very crowded in their container. So before I plant them I would like to ask if they can be divided into individual stalks/plants? And is there any video anywhere on the best way to root Coreopsis cuttings? And do they require a lot of water once established in the ground? In their plastic pot, perhaps because they look so crowded, if I don't water them at least once every day and fill the two-inch saucer the pot sits in with water, they will dry out and begin to wilt badly.

[@growitbuildit]

Hi S - the Solanna Golden Sphere is a cultivar, which is why they told you it won't produce viable seeds. It is distinctly different from the one in the video in genetics. The plant doesn't need to be divided, but it probably just needs to get into the ground so it can continue to grow and expand. I looked up this plant, and from what I gathered is that it states it will spread via rhizomes. Rhizomes are a type of root that expand out laterally and will make new plants. I don't know if this means you have a 'clump forming' rhizome plant or one that will send runners far and wide. But, because of that, if your pot is 6" diameter and the plant looks crowded, then it is probably ok to divide the plant into two using a large garden knife, pruning saw, or even chopping with a shovel. I have a video on doing this with Echinacea, you could probably follow that process. kzbin.info/www/bejne/fIfCZ2CbjZ55qKc If you do divide the plant and it results in most of the dirt coming detached from the roots, then you may want to place a lawn chair over the plant to shade it for several days after transplanting to ground. This will help shade it from the sun, and allow the roots to reestablish themselves with the soil. I would water it daily in the morning for several days. In general, coreopsis don't require supplemental water unless you get a drought. And in regards to rooting cuttings, I have not tried this on Coreopsis. But since this plant grows via rhizomes, it is possible that each Spring you could divide and gain new, free plants.

[@sphillips6357]

@@growitbuildit Thank you for the reply. I never thought of the lawn-chair shade method - I can see where that would come in handy in a lot of situations. Great suggestion. I took a chance and ripped apart the crown of one of the plants. It was very root-bound. There was no evidence of rhizome spreading in that little pot; just one plant. I tore it apart into 10 pieces that had some roots. I cut the stems back, removing the flower buds regardless if they had opened or not. I also put them into individual pots to better control the soil composition and watering and now have them in the shade of a tree. I'll gradually move them into more sun. Their final destination will be full sun which can be intense here. So far they have not shown any evidence of wilting, which is more than I can say when they were one plant in the original pot. I'll post an update here in a few months to let you know how many make it. I also put 6 stalks into a glass of water on my window sill that have no roots at all.

[@growitbuildit]

It sounds like you've done all the right things in regards to separating the plants. If there is no wilting, I think you're plants are going to do well.

[@sphillips6357]

@@growitbuildit Just thought I'd do a quick update if anyone is interested. Of the 10 pieces that had roots, the largest with the most roots looks like it might not make it. But the others are still holding their own with no wilting but no new growth yet. And that's in temperatures in the high 90's*F with occasional hot, dry winds. They are still in the shade of a tree with only about an hour of direct sun each day split between mornings and evenings. Of the six in a cup of water in my kitchen, two already have roots over a quarter inch long. I wonder how many other perennials can be propagated as cuttings in a glass of water. . .
