How to Revive Dying Daisies

Why are my daisies dying

The most common reasons for daisies dying that I see are because of not enough sunlight or dry soil. Daisies need around 6 hours of direct light and consistently moist soil to flower and remain upright. If the daisy does not have enough light or moisture, it will turn brown and die back.

However, daises are fairly resilient to temporary drought stress and can often be revived by watering and applying a mulch to conserve moisture in the soil. Where I live, we experience harsh, dry weather. I often see my daises perk up after a heat wave, even if they have drooped over completely.

Here is a table summarizing the most common reasons for daisies dying…

Symptoms of Dying Daisies:Reasons for your Daisies Dying:
Daisies drooping, wilting, and falling over:Not enough sunlight, dry soil, overwatering, high temperatures and sun, and low nutrients.
Potted daisies dying:Pots heat up quickly and dry out before the daisy’s roots can draw up the moisture they need. Pots also have a limited capacity for soil and, therefore, nutrients, which can turn the leaves yellow with a dying appearance.
Daisy leaves turning brown:A sudden heat wave and dry soil. Overwatering or slow drainage are often contributing factors. Leaves and flowers turn brown and die back at the end of the season naturally.
Daisy flower turning brown:Flowers turn brown naturally one by one and need deadheading through the season. Flowers can turn brown with curling petals due to excess wind and under or overwatering.
Daisy leaves turning yellow:The most common cause is a lack of nutrients (nitrogen in particular). Overwatering and underwatering are contributing causes.

Why are my Daisies Wilting, Drooping, and Falling Over? (Not Enough Sunlight)

  • Symptoms: Daisies with a drooping appearance.
  • Causes: Not enough sun, excess heat and afternoon sun, not enough moisture in the soil, overwatering, and low nutrient soil.

In my experience, the most common reason for daisies drooping is because they do not have enough direct sunlight.

Daises need at least 6 hours of direct sunlight to photosynthesize, flower, and prevent a drooping appearance.

Without enough light, your daisies droop over as they lack energy.

However, another common problem is that daisies can droop due to a combination of too much intense sun and heat, which causes the flowers to droop and the leaves to wilt as a way of retaining moisture in response to high Summer temperatures.

This is often a temporary reaction if the day’s heat is overwhelming, and the daisies can perk up later in the evening with cooler temperatures and a generous soak of water.

However, if you are in a very hot climate or experiencing a prolonged heat wave, then the daisies may not recover so readily.

If the soil dries out too much, the daisies will also likely droop due to a lack of moisture. Keep in mind that it may not necessarily be a lack of rainfall that is causing the deficit in soil moisture, but it may also be as a result of:

  • The soil dries too quickly (if your soil is sandy or stoney, then it may not retain enough moisture to prevent the daisies from wilting).
  • If the daises are in a pot, then pots can heat up quickly in the blazing sunshine and dry out before the daisy’s roots can uptake the moisture.
  • If the soil bakes hard in the sun and heat can cause water to trickle off the surface of the soil without infiltrating properly and reaching the roots.

It is also worth considering whether a lack of nutrients in the soil is causing your daisies to droop and fall over.

Daisies prefer fertile soil to grow their best and display the most flowers. Sandy or stony soil does not retain much nutrients or moisture, so I find that it is often the cause of daisies drooping.

This can also be a problem that I’ve seen for daisies grown in pots and containers, as the daisy’s roots can exhaust the pots of nutrients after a few years.

Whilst underwatering and poor soil are far more common causes of wilting daisies, overwatering and poor drainage can also be responsible. We need to find a happy medium to keep our daisies happy!

Daisies need the soil to retain moisture and be well-draining so that the roots are not submerged in saturated soil.

If the soil is too damp, then the excess water can exclude oxygen from the soil, which prevents the daisy’s roots from respiring, causing the daisy to droop. Eventually, the roots can rot, which is often the cause of dying daisies.

Root rot can also be problematic if the daisies are planted in pots without drainage holes in the base.

How to Revive Your Daisies That are Wilting, Drooping, or Falling Over

  • Assess how many hours of sunlight your daisies have and if it is less than 6 hours of direct sunlight. My recommendation is to cut back any shrubbery or overhanging tree branches that may be casting shade or transplant your daisies to a sunnier location in your garden.
  • I find it is best to grow daisies in 6 hours of morning sun followed by afternoon shade. The daisies experience the morning sun without contending with the higher temperatures of the afternoon heat and sun, preventing them from drooping.
  • The daisy’s soil needs to be evenly moist without being constantly saturated. Usually, a lack of moisture is the problem causing drooping daisies rather than too much. Soak the soil generously (I would recommend using a hose pipe) to ensure that the water is infiltrating properly to reach the roots where it is required.
  • Apply a layer of mulch (my favorite for mulch are compost, leaf mold, and well-rotted manure), around the base of the daisies. A mulch layer helps conserve moisture and prevents the soil’s surface from baking hard and becoming hydrophobic (water repelling). Mulch also improves the soil structure (particularly if your soil is stony or sandy) so that it is porous and well-draining yet holds moisture, which is ideal for preventing daisies from wilting. Mulch also adds additional nutrients to the soil. I cannot emphasize the importance of using mulch enough!
  • If your daises are drooping for no obvious reason, then consider whether it may be that the soil is low in nutrients or the daises have exhausted the nutrients in the soil. In this case, I recommend applying a granular all-purpose fertilizer from Miracle-Gro (or a similar product) in the Spring and Summer. I always recommend using granular fertilizer as it releases nutrients slowly to avoid problems with over-fertilizing, which can also cause plants to droop. An all-purpose fertilizer provides the daises with all the nutrients at the right concentration required to prevent a drooping, dying daisy and promote flowering.
  • If your potted daises are drooping, repotting your daisies to a larger pot may be necessary. With larger pots, there is more capacity for soil and, therefore, more capacity for retaining moisture to prevent them from drooping due to drought stress.
  • If the daises are drooping despite consistent watering, then it is likely the problem is overwatering or slow-draining soils. Daises need the soil to be moist yet well-draining to avoid drooping. Scale back your watering if the soil feels damp, and it may be necessary to transplant your daises if the soil is naturally low-lying and boggy. If the daisies are in pots, ensure they have drainage holes in the base. I personally elevate my pots on ‘feet’ or bricks an inch or so off the ground to ensure good drainage.

Why are my Daisy’s Leaves and Flowers Turning Brown?

  • Symptoms: Daisies wilting with the leaves turning brown and sometimes curling. The flower petals curl, turn brown, and die back.
  • Causes: A sudden fluctuation in temperature and light intensity. Drought stress and overwatering are often contributing factors. Daisy leaves, and flowers die back every year and need to be cut back.

In my experience, daisy leaves turn brown when there is a sudden increase in temperature and the intensity of sunlight, often from a heat wave.

The sudden increase in heat and light does not allow time for the daisy to acclimate to warmer weather which can scorch the leaves and even flowers brown.

Daisies usually droop in response to drought if the soil is temporarily dry, and your daisy’s leaves and flowers turn brown if they have been chronically short of water.

If daisies are suffering from overwatering and potentially root rot, then the leaves droop and turn brown.

A drooping appearance is usually your early warning sign that the daisies are stressed before the leaves and flowers turn brown.

However, it should be noted that whilst daisies are perennials (they come back every year), the foliage and flowers do eventually turn brown and die back every year before Winter. What time daisies turn brown depends on many factors, such as the climate and the species of your daisy.

If this happens, then there is nothing wrong with the plant, and it should come back the following year.

Daisy Flowers Turning Brown

It is worth noting that daisy flowers often turn brown after a few weeks when they are spent and should be deadheaded. The flowers turning brown is a natural part of the cycle and is nothing to be concerned about.

Deadheading redirects the daisy’s energy from developing seeds to producing more flowers and can prolong the flowering season.

However, I commonly see flower petals curl, and leaves can turn brown due to high temperatures, drought stress, and overwatering.

How to Revive Your Daises with Brown Leaves and Flowers

It is first important to establish why your daisies turn brown.

If there is a sudden heat wave and the leaves have all turned brown, then I recommend cutting the daisies back to 2 inches above the ground to stimulate regrowth, as the brown leaves do not turn green again.

If it is early in the season, there is every chance the daisies can regrow and flower, as some species are capable of flowering multiple times throughout the year.

If this keeps happening year after year and you live in a climate with high temperatures, then I recommend relocating your daises (in the Fall or Spring) to an area of the garden with around 6 hours of morning sun and afternoon shade to protect them from the harsh sun and excessive heat which should hopefully prevent them from turning brown

If you suspect drought stress is the cause of the leaves turning brown, then give the soil a good soak and apply a layer of mulch around the base of the daisies to lock in the moisture (I use compost, but manure and leaf mold are good options for mulch).

If the pots are heating too quickly in Summer and killing the daises, then re-pot your daisies into a bigger pot as it should dry out much slower and water regularly.

If your soil is boggy, then scale back the watering and assess whether the soil is draining too slowly (which can happen if they are planted in clay soil). In this scenario, my advice is to always relocate your daisies to either pots, raised beds, or an area of the garden with better drainage as a matter of urgency to prevent root rot.

Useful tip: Deadhead any brown spent flower regularly throughout the season to increase repeat flowering.

Once the leaves and flowers begin to turn brown at the end of the season then cut the foliage back to 2 inches above the ground with a sharp pair of pruners. The daisies should remerge the following year.

My Daisy Leaves Turning Yellow? (Lack of Nitrogen)

If the leaves are turning yellow, the most probable cause is a lack of nitrogen in the soil. Daisies are relatively heavy feeders and can exhaust the soil of nitrogen in the vegetative stage of growth.

I find this particularly true of Shasta daisies (which are a tall variety) and daises growing in pots. The roots can exhaust the soil of nutrients, which can turn the leaves both brown and yellow with a dying appearance or stunted growth and fewer flowers.

My solution is to amend the soil with fertilizer. Again, my recommendation is miracle-gro granular fertilizer, as this provides all the nutrients the daisies need without risking problems associated with too much fertilizer, which can burn the roots and prevent flowering.

I recommend using a granular fertilizer for daisies in Spring and Summer to prevent yellowing leaves and promote flowering.
I recommend using a granular fertilizer for daisies in Spring and Summer to prevent yellowing leaves and promote flowering.

The yellowing growth may not recover, but the added fertilizer should stimulate new green growth, displaying flowers.

If the leaves are turning yellow and the plant is wilting, then this is due to overwatering or drought stress. In this case, scale back the watering and ensure the daisies have good drainage if the soil feels boggy, whereas you should soak the ground with a hose and apply a mulch if the ground feels dry.

Key Takeaways:

  • A dying daisy is usually because of a lack of sunlight. Daisies need 6 hours of direct sunlight to avoid a drooping appearance. Drought-stressed daisies wilt with their leaves and flowers turning brown and dying back.
  • To revive dying daisies, create their optimal environmental conditions of 6 hours of morning sun, consistently moist soil, use an all-purpose fertilizer, and apply a layer of mulch around the base of the daisies to conserve soil moisture.
