How to Make Calla Lilies Bloom Again

Calla Lilies are lovely, easy-to-grow plants. They aren’t truly included in the lily family, despite their name. It’s, in reality, a member of the Araceae family. Calla Lilies can be pretty lovely when they bloom. The question is, how to make Calla Lilies bloom again?

To make Calla Lilies bloom again, you need water, sun, and sufficient nutrition. You can add phosphorus to the fertilizer as it promotes blooming well. Also, avoid using too much nitrogen, as it will hinder the blooming process.

In this article, we’ll go through the specifics of how to get your Calla Lilies to flower. We’ll also talk about what might be causing the plant to not blossom.

How to Make Calla Lilies Flower

On average, Calla Lilies bloom from June through early fall. That time is usually around September and October. They blossom for three to eight weeks typically.

The time it takes for the plants to flower is determined by many factors. These variables include the climate, light source, and other factors.

Calla Lilies flower in late spring to early summer in areas where they live for long periods.

Light

The lighting is crucial, as it’s with all plants. During off-peak hours, Calla Lilies require plenty of lighting. However, keep in mind that too much sunlight can cause their leaves to wilt. Put the Lilies in a location that receives six hours of sunshine during noon.

If you’re planting your Calla Lily inside, it will thrive in locations that face east or west. The plant will receive the necessary sunlight. Yet, it will also be given enough time in the shadow to cool. This is beneficial as the leaves won’t get damaged, and the plant will remain healthy.

Water

Calla Lilies like to grow in damp soil. However, make sure your plant isn’t too wet when you water it. The stem will decay if the soil is too moist. Also, don’t let the water dry entirely. Let the water sink in by watering your plants with a few drops of water first.

Monitor your plant every day to see whether the top is drying out. In most cases, you can water your Calla Lily once a week. However, depending on the climate, you may need to water the plants more often in warmer weather.

Keep in mind that Calla Lily grown in containers inside will need more frequent watering.

Soil and pH Levels

Calla Lilies prefer damp soils. Therefore, make sure your Lilies are planted in well-draining soil. They’re great since the soil dries quickly. As a result, it will prevent the plant from being damaged by over-watering.

If the soil in your area is sandy, you can apply fertilizer to assist your lily to thrive. Any kind of fertilizer would suffice. However, composted tea and fish emulsion fertilizers are recommended.

Calla Lilies need a soil pH level between 6 and 6.5. You can check your soil’s pH levels using a pH meter. Once you’ve got your readings, adjust the pH.

Make sure that the nitrogen levels aren’t high, as it harms the blooming process. Phosphorus can be added to enhance flowering growth.

Temperature and Dormancy

Warm temperatures, but not too hot, are preferred for Calla Lilies. They love temperatures between 60 and 80 degrees Fahrenheit. The plant becomes dormant when the temp decreases under 50 degrees Fahrenheit.

After flowering, Calla Lilies won’t flower again until they become dormant. Calla Lilies usually go dormant once a year.

There are a few things you can do if you wish to induce dormancy on your own. Don’t water your plants anymore and let the leaves dry out. Then, bring the Calla Lilies inside to a temperature of not hotter than 50 degrees Fahrenheit.

If at all possible, the place should have no access to light and minimal moisture exposure. Light has a big influence on the induction of dormancy. The sunlight stimulates the plant hormones, and it will make it more difficult to enter dormancy.

Pruning

In the fall, after the Calla Lilies have finished flowering, they should be cut back to the soil. Calla Lilies don’t need to be pruned often, but you can remove withered bloom sections to promote healthy growth.

Pruning no more than a third of the stem annually is a general rule. To prevent damaging the good stems, trim the dying stems using pruning shears. If an entire branch or a large stem is damaged, cut it all at once. In a short time, the new healthy ones will flourish.

The process is for more than just for the plant’s appeal. It’s necessary because it helps the plant stay healthy. Cutting accomplishes this by allowing for fresh development while also safeguarding the plant from damages. 

Pruning also prevents bugs, which can cause problems and lead to the death of the Calla Lily.

Why Can’t My Calla Lilies Bloom?

Don’t panic if your Calla Lilies aren’t blooming. There are a few fixable reasons for this situation. The most common causes are lack of sunlight, water, excessive nitrogen, and soil issues.

Lack of Sunlight

Calla Lilies will wither if they receive insufficient sunlight. Light has a strong impact on the plants’ development and blooming. It promotes photosynthesis as well as supplies energy.

The Calla Lily’s system processes will slow down if it can’t perform photosynthesis due to dehydration. As the plant becomes weaker, this will lead to slower development and browning of the leaves, in addition to flower loss.

Keep in mind that too much direct bright sunshine can harm your Calla Lily. As a result, make sure your plant is in the proper location. Generally, your plant should be placed to the east or west of your window.

Lack of Water

If you notice your plant’s leaves are wilting or the soil around it’s dry, it’s because it’s not getting enough water. The water demand rises as the plants develop and flower.

If your Calla Lily isn’t getting sufficient water, you should consider relocating it. Make sure the Calla Lilly isn’t dehydrated by checking on it every day.

Excessive Nitrogen

Nitrogen is a nutrient that all plants require. However, if there is too much of it, the plant may not blossom. You may notice the leaves having brown tips, even if the plant grows well and quickly.

Too much nitrogen promotes the growth of the leaves, but prevents the plant from flowering. Not only that, but it will also weaken the stems. The plant’s weak stems grow less capable of supporting it, and the plant ends up dead.

To solve this problem, use a fertilizer that is richer in phosphorus than nitrogen. Phosphorus encourages root development, blooming, and seed production.

Check Your Soil

The issue maybe with the soil or the way the plant was planted. There is a likely chance that your Calla Lily is placed too deeply in the ground.

If the plant is buried deep, it impacts the plant’s availability of water and warmth. As a result, plants placed too deeply in the ground might become frail and die quickly.

Another explanation could be that the dirt is excessively dense. High density influences water supply. Additionally, it impacts the root development as well as the airflow through the ground. As a result, there’s a chance that your plant isn’t getting enough nutrition or water.

If any of these reasons apply to your Calla Lily, you can re-pot it properly to ensure it receives what it needs.

Wrap Up – How to Make Calla Lilies Bloom Again

Calla Lilies are lovely plants. You don’t need any complex materials to make them bloom. In actuality, all you need to do is maintain a healthy mix of water, sunlight, and nutrition.

Other factors, including pruning, soil quality, and temperature, all have a role as well. However, these variables are rather basic to manage.

Soon, you’ll have gorgeous blooming Calla Lilies decorating your garden.
