To grow marguerite daisies successfully, you need to provide them with plenty of sunshine, well-drained soil, and regular deadheading to encourage continuous blooms.
These cheerful, shrub-like perennials, often treated as annuals in cooler climates, are surprisingly easy to care for once you understand their basic needs.
Whether you’re planting them in garden beds, borders, or containers, learning how to grow marguerite daisy plants will reward you with a long season of colorful flowers.
In this post, we’ll explore the best practices for growing marguerite daisies, from planting and watering to pruning and winter care.
Let’s dig into everything you need to know to help your marguerite daisies thrive.
How to Grow Marguerite Daisy: The Essentials
The key to learning how to grow marguerite daisy plants lies in mimicking their native Mediterranean habitat.
These daisies thrive with full sun exposure, moderate water, and soil that doesn’t stay soggy.
Here are the fundamental steps to get your marguerite daisies off to a great start.
1. Choose the Right Location
When you grow marguerite daisies, location is everything.
They need at least six hours of direct sunlight each day to produce the most flowers.
In hotter climates, a little afternoon shade can help prevent the blooms from fading too quickly, but too much shade will make them leggy and reduce flowering.
Make sure the spot you pick has good air circulation to keep fungal diseases at bay.
2. Prepare the Soil Properly
Marguerite daisies prefer a slightly acidic to neutral soil pH, ideally between 6.0 and 7.0.
Before planting, work in some organic compost to improve drainage and add nutrients.
If you’re growing marguerite daisies in heavy clay soil, consider planting them in raised beds or containers instead.
Sandy or loamy soil that drains quickly is perfect for these plants, as they don’t like to sit in water.
3. Watering Without Overdoing It
While you grow marguerite daisies, finding the right watering balance is crucial.
They prefer consistently moist soil but will suffer if the roots become waterlogged.
A good rule of thumb is to water deeply once or twice a week, allowing the top inch of soil to dry out between waterings.
During hot, dry spells, you may need to water more frequently, especially for plants in containers.
Always water at the base of the plant to avoid wetting the foliage, which can lead to mildew.
Planting and Caring for Your Marguerite Daisies
Once you’ve got the basics down, it’s time to get your hands dirty and actually plant your marguerite daisies.
Whether you’re starting from nursery plants or seeds, the process is straightforward.
Let’s walk through the planting steps and the ongoing care your daisies will need to stay healthy and vibrant.
1. Planting from Nursery Pots
The easiest way to grow marguerite daisy plants is to start with young plants from a garden center.
Dig a hole that’s slightly larger than the root ball and place the plant at the same depth it was in the pot.
Backfill with soil, gently firm it down, and water thoroughly to settle the roots.
Space multiple plants about 18 to 24 inches apart so they have room to spread and breathe.
2. Growing from Seeds
If you’re more adventurous, you can grow marguerite daisies from seeds.
Start seeds indoors about 8 to 10 weeks before the last expected frost.
Sow them on the surface of a moist seed-starting mix and press them in lightly, as they need light to germinate.
Keep the soil warm and consistently moist, and you should see seedlings in 14 to 21 days.
Once the danger of frost has passed, harden off the seedlings and transplant them outdoors.
3. Fertilizing for More Blooms
To encourage prolific blooming, feed your marguerite daisies every few weeks during the growing season.
Use a balanced, water-soluble fertilizer diluted to half strength.
Alternatively, mix a slow-release fertilizer into the soil at planting time.
Avoid over-fertilizing, as this can lead to lush foliage at the expense of flowers.
4. Pruning and Deadheading
Regular deadheading is one of the most important tasks when you grow marguerite daisy plants.
Remove spent flowers by pinching them off at the stem to encourage the plant to produce new buds.
In midsummer, if your daisies start to look tired or leggy, give them a hard prune by cutting the plant back by about one-third.
This will rejuvenate the plant and promote a fresh flush of growth and blooms.
Overwintering and Common Problems
Depending on your climate, you might be able to keep your marguerite daisies year after year.
In USDA zones 9 through 11, they are perennial and can stay outdoors all winter.
In cooler zones, they’re often grown as annuals, but you can overwinter them indoors with a little effort.
Here’s how to handle the colder months and tackle common issues.
1. Overwintering Indoors
Before the first frost, dig up your marguerite daisies or bring their pots inside.
Place them in a bright, cool room with temperatures around 50 to 60°F (10 to 15°C).
Reduce watering significantly, allowing the soil to dry out more between waterings.
In spring, once the danger of frost has passed, you can move them back outside to grow marguerite daisies again.
2. Dealing with Pests
Aphids and whiteflies are the most common pests you’ll encounter when you grow marguerite daisy plants.
Check the undersides of leaves regularly and wash off small infestations with a strong jet of water.
For stubborn problems, use insecticidal soap or neem oil, making sure to cover the entire plant.
Keeping your daisies healthy and well-watered will also make them less susceptible to pest attacks.
3. Preventing Diseases
Root rot and powdery mildew are the main diseases that affect marguerite daisies.
Root rot is usually caused by overwatering or poor drainage, so be careful not to let the soil stay soggy.
Powdery mildew appears as a white, powdery coating on leaves, especially in humid conditions.
To prevent it, ensure good air circulation and water at the base of the plant, not overhead.
