Portulaca Leaves Are Closed – Why? What To Do?
Portulaca, also called moss rose, often exudes the utmost beauty when it blooms. But you can't help but wonder why your Portulaca’s leaves remain closed. Also, what can you do to make the plant bloom? We researched for your convenience, and here’s what we found.
Portulacas may not bloom, regardless of the time of day, if they’re experiencing certain issues. Some problems you may come across often range from insufficient sunlight to a pest infestation. Once you find the source of the issue, use the appropriate actions to solve it and open your portulaca plants.
So continue reading as we talk about the possible reasons why your portulaca doesn’t flower. Also, we’ll tackle some potential solutions that may help maintain the plant’s blooming cycle.
Reasons Why Portulaca Leaves Don’t Bloom
Portulacas often require at least 6 hours of direct sunlight per day. It’s a plant that thrives in dryness and typically only requires adequate watering daily.
Despite Portulacas having minimal water requirements, this doesn’t mean you shouldn’t disregard its moisture requirements. Generally, you don’t need to water it every day, particularly if you live in a location that rains frequently, but you may have to apply a light spritz of water if rain hasn't falllen in your area as of late.
Portulacas planted in soil that gathers significant moisture might not be the best growing scenario. Bear in mind that this plant often flourishes in dry environments, particularly beachfront.
Crowded planting environments may also prevent moss roses from blooming. Gardeners should follow adequate spacing between portulacas to ensure their proper growth.
Perhaps you’re caring for your portulaca plants religiously, but they’re still not blooming. If so, this issue may lie with the season. It’s best to start planting a portulaca from the first day of summer. Then, it should bloom before the cold season arrives.
Insects like aphids and spider mites can wreak havoc on your portulaca plants. Aside from these bugs, chipmunks may also find your portulacas alluring. These pests may destroy the well-being of your portulacas, preventing them from blooming properly.
At this point, you might be curious to know if portulacas attract hummingbirds. You can read our post on that topic to know the answer.
How Do You Make Portulaca Bloom?
Different solutions are available to help increase the likelihood of your portulaca plants opening and flowering. Some methods you may use are:
Eliminate And Prevent Pests
As mentioned earlier, aphids and spider mites are among the main suspects that ruin your portulacas before they flower. Make sure to act quickly and apply the correct measures to eliminate and prevent these pests from destroying your plants.
You’ll know if aphids are eating away your garden, including your portulaca plants, if you see signs like:
- Discoloration, curled, and/or misshapen leaves
- Sticky residue on the leaves
- Fungal or sooty mold growth
- Nearby plants show the symptoms mentioned above
On the other hand, some symptoms to watch out for if you have a spider mite problem are:
- Small white or yellow spots on the leaves
- Needle-like objects stuck on the leaves
- Silky residue
- Discoloration of the plant
You may use chemical insecticides to eliminate pests and prevent these insects from eating your moss roses, but the harsh components may also harm the plants you’re trying to protect.
Before resorting to this, apply solutions like spraying neem oil on your portulacas. That organic oil can help stop aphids from eating those plants. As for spider mites, you may need to use insect traps and place them in strategic locations around your portulaca plants.

Place In The Correct Location
Remember, portulacas generally love direct sunlight. So placing these plants in shady areas around your property may not be the best idea.
If you already planted your portulacas, follow these steps to transplant them:
- Prepare the new location by digging and loosening a shallow trench of about 3 to 4 inches deep.
- Remove rocks, roots, and other debris from the trench.
- Spray a small amount of water on the portulaca plants you’re about to transpose during the night before the relocation.
- On the next day, dig around the portulaca with a trowel. Lift the plant from its old placement afterward.
- Transplant the lifted plant to the new location quickly.
- Once the portulacas are in the new location, water them again lightly.
Deadheading is the process of removing dead or diseased parts of plants. It’s a procedure that helps secure the well-being of plants like portulacas. Failure to use this technique may result in the entire plant dying from illnesses and viruses.
Here are the steps to deadhead your moss roses:
- Locate the dead or diseased parts of the portulaca.
- Snip the bad components with shears or pruners. Make sure to cut below the dead or sick parts.
- Discard the cut areas properly.
Bear in mind that you shouldn’t throw the cut parts near your healthy portulacas. Otherwise, the rotting components may infect your plants which are still healthy!

Can You Overwater Portulaca?
Overwatering a portulaca may cause its root to rot. This plant typically prospers in dry conditions. Gardeners only need to apply a small amount of moisture to their portulacas for the best results.
How Do You Save A Dying Portulaca?
Another reason why you’re portulaca plant is having trouble blooming is that it might be dying. If so, these methods may help you in restoring its health:
Method #1: Cut And Grow
Break or cut the dying stems and leaves of your portulaca. Remove any ill or dying areas of the cut part. You can then plant the broken or cut component in the soil. Care for the newly planted stub normally.
Method #2: Transplant To A Nearby Plant
Transfer the dying portulaca to a location near another plant with a rooting hormone. The other plant then becomes a catalyst to help the poor portulaca. An ideal candidate for this method is a place near an aloe vera plant.

Method #3: Collect And Plant The Seeds
Dying portulaca plants may still have their seeds intact. Remove the seeds from a dead bud and plant them in the soil. Care for the seeds as you’d normally do with a regular portulaca. If done properly, you should be able to see buds growing where you planted the seeds.
Method #4: Plant The Leaves
If your portulaca plant is at death's door, cut the leaves and the stems attached to them. Next, plant the leaves in the soil and spray them with water lightly. If done correctly, you should see some roots forming out of the leaves after a while. You can then transfer those leaves and care for them normally.

How To Propagate Portulaca?
Following proper propagation techniques may help portulacas remain healthy. Allowing these plants to maintain their well-being can also help sustain their blooming cycles.
So, follow these steps if you need a guide to spread portulaca in your garden properly:
- Take a healthy leaf or cutting from a well-cared portulaca.
- Place the leaf or cut part with its end down into damp potting soil.
- Wet the leaf or cut part lightly upon transferring it.
- Water daily if needed and check signs for growth.
Tip: If you don’t have a healthy portulaca for propagation, start the plant’s growth process by using seeds instead.
