Daisies are among the most forgiving flowers you can grow, but they still have preferences that make the difference between a plant that limps along and one that blooms generously all season. Most daisies share a core set of needs: full sun, well-drained soil, moderate water, and occasional feeding. The details shift depending on whether you are growing Shasta daisies in a perennial border, Gerbera daisies in pots on a patio, or English daisies tucked along a garden path, and those differences are worth knowing before you plant.
Sunlight and Placement
Almost every daisy in the family thrives with at least six hours of direct sunlight per day. Shasta daisies, African daisies, and Gerbera daisies all produce more flowers and sturdier stems when they get full sun. In hot climates where afternoon temperatures regularly push above 90°F (32°C), a spot with morning sun and light afternoon shade helps prevent scorched petals, especially on Gerbera daisies, which are more heat-sensitive than their cousins. English daisies (Bellis perennis) are the exception on the other end: they actually prefer cooler conditions and tolerate partial shade better than most other types.
When picking a planting spot, think about air circulation too. Daisies planted in tight, stagnant corners are more prone to fungal problems like powdery mildew. A location with gentle airflow around the foliage dries leaves faster after rain or watering and keeps disease pressure lower.
Soil That Drains
Drainage is the single most important soil quality for daisies. Roots sitting in waterlogged soil invite crown and root rot, and once rot takes hold the plant collapses quickly. A loamy soil that holds some moisture but lets excess water pass through is ideal. If your garden soil is heavy clay, work in compost or coarse perlite before planting to open up the structure. Sandy soil drains fast but dries out too quickly; mixing in organic matter helps it retain enough moisture without becoming soggy.
Most daisies prefer a slightly acidic to neutral pH, somewhere in the range of 6.0 to 7.0. You do not need to be precise about this unless your soil is extremely acidic or alkaline. A basic garden soil test from a local extension office or a home kit will tell you whether you are in the right range. If your pH is far off, amending with sulfur (to lower) or lime (to raise) a few weeks before planting gives the soil time to adjust.
Watering Without Overdoing It
Daisies want consistent moisture during their active growing season, but they resent soggy roots. A good rule of thumb is to water when the top inch or so of soil feels dry. In most climates, that translates to roughly one inch of water per week during spring and summer, whether from rain or a hose. In containers, the soil dries faster, so you may need to check every day or two during hot spells.
Water at the base of the plant rather than from overhead. Wet foliage that stays damp overnight creates the exact conditions fungal pathogens love. Drip irrigation or a simple watering can aimed at the soil line does the job. Mulching around the base with two to three inches of organic mulch (shredded bark, straw, or compost) slows evaporation, keeps roots cooler in summer, and reduces splashing that can spread soil-borne diseases onto lower leaves.
Overwatering is riskier than underwatering for most daisy types. Gerbera daisies in particular are susceptible to Phytophthora crown and root rot when soil stays consistently wet. Research on managing this disease in Gerbera production found that fungicide drenches could prevent or reduce Phytophthora damage, but growers still had variable results depending on the year and the specific product used, which underlines how much easier it is to prevent the problem with good drainage than to fix it chemically after the fact.1Plant Health Progress.

Feeding Your Daisies
Daisies are not heavy feeders compared to roses or vegetable crops, but they do appreciate regular nutrition during the growing season. A balanced, all-purpose fertilizer applied every four to six weeks from spring through midsummer keeps most types happy. You can use a granular slow-release product worked lightly into the soil around the base, or a diluted liquid fertilizer applied with watering.
If you prefer organic options, they work well. A study on Marguerite daisies compared organic fertilizer applied at different rates and frequencies against a standard chemical fertilizer. Organic fertilizer applied at higher rates produced plant growth and flower sizes comparable to those achieved with chemical fertilizer. Chemical fertilizer did still produce more flower buds and blooms per pot overall, but the gap narrowed at higher organic application rates and more frequent feeding schedules.2Asian Journal of Science and Technology Research. Growth and Flower Yield of Marguerite Daisy (Argyranthemum frutescens) Cultivated Using Organic Fertilizer at Different Rates and Frequencies In practical terms, if you go organic, apply it a bit more generously and more frequently than you might guess. Compost tea, fish emulsion, or a well-balanced organic granular product all work.
Stop fertilizing by late summer for perennial types like Shasta daisies. Pushing new growth late in the season leaves tender foliage vulnerable to frost damage. Annual daisies that you plan to pull at season’s end can be fed right up until they stop blooming.
Deadheading and Pruning
Deadheading spent flowers is the single easiest way to keep daisies blooming longer. When a daisy flower fades and starts setting seed, the plant redirects energy from producing new blooms to ripening that seed. Snipping off the spent flower head, stem and all, tells the plant to try again. For Shasta daisies, cut the stem back to just above a set of healthy leaves rather than just plucking the flower head. For Gerbera daisies, grab the stem at its base near the crown and twist it off cleanly.
If your Shasta daisies start to look leggy or floppy by midsummer, you can cut the entire plant back by about a third. This often triggers a fresh flush of compact growth and a second round of blooms in late summer or early fall. English daisies that get shaggy after their spring bloom respond well to a similar shearing.
For perennial types, leave the final flush of spent blooms in place as fall arrives. Those basal leaves and stems provide some insulation for the crown over winter. You can clean up dead foliage in early spring when you see new green growth emerging.
Common Pests
Daisies attract a predictable cast of garden pests. Aphids cluster on new stems and flower buds, distorting growth and leaving sticky honeydew. A strong spray of water from the hose knocks most of them off, and ladybugs, lacewings, and other predators usually keep populations in check if you avoid broad-spectrum insecticides. Slugs and snails chew ragged holes in leaves, especially on English daisies growing in damp shade. Beer traps, copper barriers around pots, or iron phosphate baits handle them without harming pets or wildlife.
Leaf miners sometimes tunnel through daisy foliage, leaving pale, winding trails. The damage is mostly cosmetic. Picking off and discarding affected leaves is usually enough. Spider mites can show up in hot, dry weather, particularly on Gerbera daisies grown indoors or in greenhouses. Fine webbing on the undersides of leaves and a stippled, faded look to the foliage are the giveaway. Raising humidity around the plant, misting leaves, or using insecticidal soap handles mild infestations.
Diseases to Watch For
Powdery mildew is probably the most common fungal disease daisy growers encounter. It shows up as a white or grayish powdery coating on leaves, usually when days are warm and nights are cool with high humidity. Good air circulation and avoiding overhead watering go a long way toward preventing it. If it does appear, research on Gerbera daisies found that spraying with electrolyzed oxidizing water twice a week significantly reduced powdery mildew, and alternating those sprays with conventional fungicides also worked well.3Plant Disease. Evaluation of Electrolyzed Oxidizing Water for Management of Powdery Mildew on Gerbera Daisy For home gardeners, neem oil or potassium bicarbonate sprays are widely available alternatives that work on the same principle of disrupting the fungal coating.
Crown and root rot, as mentioned earlier, is a serious threat to overwatered daisies. Infected plants wilt suddenly even though the soil is moist, and the crown at soil level may look dark and mushy. Prevention through proper drainage is far more effective than trying to save a plant that already has it. If one plant in a group develops rot, remove it promptly and avoid reusing the soil in that spot for daisies without amending it heavily.
Botrytis (gray mold) occasionally hits daisy flowers during prolonged wet weather, turning petals brown and fuzzy. Removing affected blooms and improving airflow are the main remedies. Aster yellows, spread by leafhoppers, causes bizarre growth distortions including green, stunted flowers and yellowed foliage. There is no cure; infected plants should be removed and destroyed to prevent spread.
Growing Daisies in Containers
Container growing works especially well for Gerbera daisies, African daisies (Osteospermum), and compact Shasta varieties. The key is choosing a pot with drainage holes and using a well-draining potting mix rather than garden soil, which compacts in pots and chokes roots. A mix formulated for general containers, or one you blend yourself from peat or coir, perlite, and compost in roughly equal parts, gives the right balance of moisture retention and drainage.
Container daisies need more frequent watering and feeding than those in the ground because the limited soil volume dries out and depletes nutrients faster. Check moisture daily during warm weather. A diluted liquid fertilizer every two to three weeks during the blooming season keeps potted daisies well fed. Move containers to a sheltered spot or bring them indoors before the first frost if you are growing tender types like Gerberas in a climate where they would not survive winter outside.
Pot size matters. A container that is too small restricts root growth and causes the plant to dry out rapidly; too large and the excess soil stays wet and invites root problems. For a single Gerbera daisy, a pot about 8 to 10 inches in diameter works well. Shasta daisies, which have more spreading root systems, do better in wider pots, around 12 to 14 inches for a single clump.
Overwintering Perennial Daisies
Shasta daisies and English daisies are cold-hardy perennials in most temperate climates, returning reliably year after year once established. After the first hard frost kills the top growth, leave the dead foliage in place through winter. It provides a layer of insulation for the crown. In late winter or early spring, once you see new green rosettes forming at the base, cut back the old brown stems and clear away debris.
In very cold climates with inconsistent snow cover, adding a few inches of mulch (straw or shredded leaves) over the crown after the ground freezes gives extra protection. Pull the mulch back as temperatures rise in spring so the emerging growth does not rot underneath it.
Gerbera daisies are a different story. They are perennial only in frost-free or very mild climates, roughly the equivalent of USDA zones 8 through 11. Everywhere else, you either grow them as annuals, or you bring potted Gerberas indoors before frost and keep them in a bright, cool spot through winter. Reduce watering dramatically during this dormant period. They do not need fertilizer again until spring growth resumes.
Dividing and Propagating
Perennial daisies benefit from division every two to three years. Over time, clumps become crowded, and the center of the plant may die out while growth continues around the edges. Dividing reinvigorates the plant and gives you new plants for free. The best time to divide is early spring, just as new growth appears, or in early fall when the weather cools but the ground is still warm enough for roots to establish.
To divide, dig up the entire clump, shake off loose soil, and pull or cut it into sections. Each section should have a healthy chunk of roots and several growing points. Replant the divisions at the same depth as the original, water well, and they will establish quickly. Discard the woody, played-out center of the old clump.
Growing daisies from seed is also straightforward, especially for Shasta and English types. Sow seeds indoors about six to eight weeks before your last expected frost, barely covering them with soil since most daisy seeds need light to germinate. Keep the soil consistently moist and warm, around 70°F (21°C). Seedlings are typically ready to transplant outdoors after the last frost date, once they have developed a couple of sets of true leaves. Expect blooms in the first or second year depending on the variety.
Why Daisies Sometimes Stop Blooming
A daisy that produces plenty of leaves but few flowers is usually telling you one of a few things. Too much shade is the most common culprit, especially if surrounding plants or trees have grown and now block sunlight that was there when you first planted. Too much nitrogen fertilizer pushes lush green growth at the expense of flowers; if you have been feeding heavily, switch to a fertilizer with a higher middle number (phosphorus) relative to nitrogen. Overcrowding in an undivided clump also suppresses blooming, as plants compete for light and nutrients.
For Gerbera daisies grown indoors, insufficient light is almost always the problem. They need the brightest window you have, and even then a supplemental grow light during short winter days helps. Low humidity indoors can also stress Gerberas into dropping flower buds before they open.
English daisies sometimes go dormant and stop flowering in the heat of summer, then perk back up in cooler fall weather. This is normal behavior, not a sign of trouble. Shasta daisies that fail to bloom in their first year from seed are also on schedule; many cultivars put their energy into root development the first season and bloom the second.
Companion Planting With Daisies
Daisies’ open, flat flower structure makes them excellent at attracting beneficial insects. Hoverflies, parasitic wasps, and ladybugs all visit daisies for pollen and nectar, and those same insects prey on aphids and other pests throughout your garden. Planting daisies near vegetables or other ornamentals that suffer from aphid pressure creates a natural pest-control corridor.
Aesthetically, the upright form of Shasta daisies pairs well with plants that spill or mound, like catmint, lavender, or low-growing sedums. African daisies and Gerberas, with their vivid colors, look striking alongside silver-foliaged plants like dusty miller or lamb’s ear. English daisies, being small and ground-hugging, work as edging along pathways or tucked between stepping stones. Avoid planting daisies directly next to aggressive spreaders that will crowd them out; give each plant enough room to get full sun on its foliage and good airflow around its base.
