A perennial herbaceous member of the Acanthaceae family, Mexican petunia is evergreen. Ruellia brittoniana is another name for it, but R. simplex is chosen because it was the name given to the plant when it was initially reported in Cuba. Mexican petunia is a bushy, woody-based plant that is simple to grow through cuttings, division, and seed. Some people even describe it as aggressive. Even though it reproduces readily, be aware that some cultivars, such as “Purple Showers,” are sterile and may instead spread via rhizomes. In the wild, it normally reaches a height of 3 to 4 feet, but in gardens, it only reaches 2 to 3 feet.
Although flowering is greatest in full light, Mexican petunia prefers medium to damp soil that is healthy and well drained as well as full sun to partial shade. It may survive in zones 7 or even lower if grown as an annual but normally grows in zones 8 to 10. Mexican petunias are tolerant plants that may thrive in hot, humid weather, varying soil moisture levels, and drought situations after they have established themselves. Deer rarely cause damage to it. Although each flower only blooms for one day, the flowers are incredibly stunning. After blossoming, trim stems to promote fresh blooms.
Mexican petunia plants quickly naturalized in South Carolina, Texas, and Hawaii. They spread by rhizomes and self-seeding in gardens. Despite having outstanding flowering qualities, the Florida Exotic Pest Plant Council (FEPPC) has classified this species as a Category One invasive species since it has been observed to overrun natural regions and supplant native vegetation in the State of Florida.
Plant pests, diseases, and other issues: No significant issues with insects or diseases. It’s exceedingly challenging to eliminate plants once they’ve been established in the wild. Plants can spread invasively through rhizomes and self-seeding. The earth still contains seeds. Alternatives need to be taken into account; see the recommendations in the left hand column.
What creatures consume Mexican petunias?
Petunias attract attention, though not usually in a good way, with their lavish flowers, brilliant colors, and alluring scent. They are a gardener’s dream and relatively simple to maintain, yet they may host strangers! What is eating your petunias, you may question if you grow them and have seen holes in the leaves or stems without blooms?
Many insects, including caterpillars like tobacco budworms and variegated cutworms, enjoy eating petunias. They are also consumed by aphids, whiteflies, slugs, and snails. Petunias are also consumed by animals like rabbits, chicks, squirrels, mice, deer, and mules. To prevent this from happening to your plants, there are natural and secure methods.
Now that you are aware of the various animals that consume petunias, let’s look at this in more detail below. We’ll talk about how to stop it once it starts as well as how to stop it before it starts. We will also go through eco-friendly, safe methods for getting rid of these pests.
So please continue reading if you’re interested in finding out more about what is consuming your petunias and how to stop it.
Are petunias immune to deer?
Petunias are unfortunately not deer-resistant. Your petunias will be seen by deer, just like any other succulent, and they will decide to eat them right away.
Where should Mexican petunias be planted?
Mexican petunia, often known as ruellia, may add color and height to your summer borders. This low-maintenance plant grows to a height of 3 feet (although there are dwarf types that stay shorter) and produces waves of petunia-like blue, white, or pink flowers throughout the summer. The colorful insects swarm to the fragrant petals of Mexican petunia, making it a perfect choice for butterfly gardens. Additionally, Mexican petunia is a necessary plant for butterfly gardens because various species of butterflies need it as a host plant for their larvae to feed on. Mexican petunia will frequently self-sow after it is established and spread widely in the garden, so plant it in areas where you can monitor it or in sizable container gardens. Deer can’t eat Mexican petunia. Hardy in zones 9 through 11.

Mexican Petunia Growing Instructions
It thrives and blooms best in broad sun or light shade for Mexican petunia. Although it can grow in the shade, it won’t blossom as much and will appear lanky and leggy. Mulch the plants to maintain regular soil conditions, especially in hot, dry weather, as this sun-loving perennial prefers rich, somewhat damp soil. Mexican petunias can be grown as annual flowers in the northern hemisphere. Mexican petunia may spread quickly, so plant it in an area where you can limit it.
Restrictions may apply to some of these plant’s varieties since they are thought to be invasive. Before planting, check the local laws. At Costa Farms, only non-invasive hybrids are grown.

Rabbits consuming Mexican petunia
Forget about how cuddly, fluffy, and soft bunnies are. These creatures can be among a gardener’s most dreaded pests since they can destroy entire harvests in a single night. Young, fragile shoots are preferred by rabbits, which also enjoy lettuce, beans, and broccoli in particular. They enjoy nibbling on petunias, marigolds, pansies, and gazanias among other flowers. Young bunnies are naturally interested and like to try new plants, especially those that are said to be resistant to them. For advice on keeping rabbits out of your garden, continue reading.
What flowers in pots won’t deer eat?
- White-tailed deer damage to nurseries has been researched by researchers from the University of Rhode Island. They found that deer had a fondness for hostas, daylilies, and English ivy in particular.
A few study participants made the interesting observation that deer appear to choose fertilized plants over those that haven’t.
Which Plants Deer Don’t Want to Eat
It should come as no surprise that deer tend to avoid harmful plants. Deer steer clear of common flowers with toxicity like daffodils, foxgloves, and poppies.
- Deer also have a propensity to avoid plants with powerful odors. Flowers like peonies and bearded irises, as well as herbs like sages, decorative salvias, and lavender, are simply “stinky to deer.
- Would you like to consume anything sharp? Deer don’t either (unless they’re in a pinch). They avoid eating plants like lamb’s ear on their favored menu.
Deer-Resistant Plants for Shade
- Bleeding hearts are one of our favorite perennials that can withstand deer (Lamprocapnos spectabilis, aka Dicentra spectabilis).
- Astilbe are plants that thrive in shade and are resistant to deer. Bridal Veil, Visions, and Fanal asters combine well.
Deer-Resistant Plants for Sun
- The Coreopsis verticillata ‘Zagreb’ variety has a long blooming season from May through September and attracts butterflies but not deer.
- The perennial Liatris spicata ‘Kobold’ or Blazing Star is another sun-loving plant that isn’t a favorite among the deer.
- One of our favorite native plants, Echinacea purpurea, attracts pollinators.
- Salvia x sylvestris, sometimes known as wood sage, is another sun-lover.
- Last but not least, a popular type of Shasta Daisy that deer do not prefer is Leucanthemum x superbum “Becky.”
List of Top Deer-Resistant Plants, Flowers, and Shrubs
Deer-resistant plants have been identified through research as those that are less likely to be consumed by deer. The list is below. Here is a list of common plants that deer rarely or never seriously harm. Remember that there are no plants that are entirely resistant to deer; this is the first rule of deer proofing.
Mexican petunias should be pruned in the winter.
Typically, a Mexican petunia only needs one annual pruning in late winter or early spring to remove any damaged, weak, or unwelcome stems back to the plant’s root system. During the flowering season, trimming spent flower stalks helps keep the garden looking tidy. Every few years, in the spring, trim Mexican petunia clumps back to a few inches above the ground to revitalize them.
The spread of this plant can be controlled with specific pruning methods. Cut off any spent Mexican petunia blooms before they set seed and pluck away any stems that have fallen to the ground and become rooted in the soil.
Which plants irritate deer the most?
According to Hyland, deer typically avoid plants with fragrant foliage like sage and rosemary. Additionally, they stay away from statuesque plants like yews, hollies, and boxwoods. Deers will not enjoy anything spiky or fuzzy, so take the texture of the plant into consideration.
Do coffee grounds deter opossums?
It’s upsetting to discover when you get up in the morning that all the time and effort you put into your garden has suddenly turned into a mess, with deer to blame.
Deer have keen senses of smell that they employ to locate readily available food sources. The bitter scent of used coffee grounds may warn deer that people are close and keep them away from your property even if there is no scientific proof that they will scare off deer.
Deer, despite their harmless appearance, frequently enter your property at night to either consume your plants or damage them by rubbing their antlers on your trees. In essence, can deer really be stopped in their tracks by coffee grounds?
Will marigolds deter opossums?
All marigold types repel deer due to their overpowering, offensive aroma. However, signet marigolds (seen in the image) are frequently used in cooking because of their milder citrus flavor and aroma.
Zones 9–10; cultivated elsewhere as an annual exposure to the sun Late spring until frost is the blooming season. Variable, ranging from 6 inches to 4 feet tall and 6 inches to 2 feet wide.
Do Mexican petunias reappear annually?
I have a about 4-year-old Mexican petunia called a Ruellia. All of the stems died back in 2013 as a result of the freeze. The plant recovered well and produced lovely flowers after I clipped them all off at the ground level.
The plant appears to have seen very little dieback this winter. Should I remove every stem at ground level or just the ones that have been harmed by frost? Does it bloom from the old stems as well or just the new wood?
In response, Mexican petunia is categorized as a herbaceous perennial, meaning that if it gets too cold, it freezes to the ground and then grows back from the root. Since it blooms in the summer, the flowers appear on young growth. Older wood and the young growth at the bottom will both produce flowers.
It will grow from the root and bloom much like it did in 2014 if you prune it to the ground once more, as if it had frozen back. That is the simple method.
The second choice is to maintain it at this height while lowering everything weak or dead to the ground. The remaining stems should then be pruned back to the desired branching height. Shearing or cutting it back will make it grow more thickly and blossom above the sheared area.
Your plant will grow taller if you use the second strategy. Use the first approach if keeping it small is a need.
Do not forget to fertilize it right away with an all-purpose fertilizer for growing flowers, such as a fertilizer for roses, fruit trees, tomatoes, or something comparable.
The avocado I planted outside last year came from its pit. I put it in a pot and carried it inside when the weather started to become colder. The older leaves are starting to dry out and turn brown. Since bringing it inside, I fertilized it once. Every other day, I give it a gentle watering because the leaves are starting to curl from dehydration.
The primary cause of leaves falling from an avocado brought inside is a change in the duration or intensity of the light. Additionally, moving it from the soil to a container can promote leaf drop. A irrigation issue could be the reason for leaf fall. Insect pests like mites are a fourth potential.
Plants raised outside produce a distinct kind of leaf than those raised indoors. Sun leaves, which are leaves that are grown outdoors, fall off as the light intensity changes. A shade leaf is a new growth that the plant produces that is thinner, bigger, and more numerous.
Leaves can fall off due to root system disruption as well. It’s referred to as transplant shock. Additionally, a change in watering schedule might result in leaf drop. If there are mites on your indoor plants, they may have relocated to the avocado due to the fruit’s susceptibility to mite problems.
Ensure that the avocado receives as much light as you can. Ideally, a window facing south should be used. For it to remain healthy and avoid growing spindly, you must provide it with several hours of sunlight.
Until water is coming out the bottom of the container, moisten the soil inside. Wait to water again until you see a significant shift in the container’s weight. Using a pencil or a soil moisture meter is another way to determine the amount of moisture in the soil.
See how easily a pencil descends by pressing it into the ground. In dry dirt as opposed to moist earth, a pencil is more challenging to push. After removing the pencil, you can feel the end to gauge its moisture level. A soil moisture meter, which is readily accessible at any nursery or garden center, is another option.
Mites are a frequent issue with avocados. Slap a fading leaf against some white paper to check for mites. Under glaring light, they scrutinize the page.
You can observe tiny mites the size of a pencil dot crawling across the surface if you have good vision or are using a magnifying glass. If you softly drag your fingertips across the paper’s surface as well, the mites will leave a red stain.
If your plant has mites, you should apply horticultural oil all over it to suffocate the mites. Sprays of soap are effective at removing live mites.
Small snails have been climbing up my red brick planter this fall, I’ve noticed. Many of those shells are scattered over my yard and pots. In contrast to the past, powdery mildew has suddenly appeared on my roses. I believe that the snails are to blame for my lawn’s thinning. Older mulberries in my yard provide me with some shade. I emailed you some images of my backyard.
After looking at the photographs and reading your explanation, I believe that the shade is responsible for a number of issues. Plants and soil keep wet longer in areas of increased shadow.
Snails and slugs prefer prolonged wetness. The likelihood of developing powdery mildew and other illnesses rises with increased shade. Lawns narrow and finally collapse as a result of more shade.
Lower branches on the trees can be cut off to improve things. More light will enter your property as a result of limb removal, which will also boost the roses, lessen disease issues, thicken the lawn, and lessen snail issues.
Fescue and rye, two cool-season lawn grasses, require filtered sunshine or at least five hours of direct sunlight daily, with no more than 50% of the lawn being shaded. Lawns and floral plants will suffer if they are shaded more than this.
Lawns that are shaded cannot endure any type of traffic. In the more shady regions, the lawn will start to dwindle and the ground will become barren.
In the shade, flowering plants like roses produce fewer and of inferior quality blooms. The shade is ideal for powdery mildew. Water splashes are also enjoyed by powdery mildew. Powdery mildew will spread from rose to rose if there is overhead irrigation that splashes on the foliage and they are shaded.
Snails are challenging to manage. Use bait and traps to keep them under control. Put moist newspapers or cardboard between the plants to catch snails. Snails and slugs enjoy gatherings under damp paper or cardboard when the sun rises.
To dispose of them, gather them up from the ground or the underside of the cardboard and place them in a plastic bag. If you do this consistently, let’s say once a week, you can reduce their numbers.
Baits are also effective against snails. According to the label, they are normally distributed about the plants on a regular basis. These can be bought online or at the majority of nurseries and garden retailers.
I recently received a sizable bag of California-grown Fuyu persimmons that I had produced myself. Will the Fuyu persimmon tree endure the harsh climate in Las Vegas? The tree won’t even grow here.
The majority of persimmon varieties can grow in this environment. The variety known as “Hachiya” is one that I wouldn’t advise growing here, but Fuyu, gigantic Fuyu, coffee cake, and the majority of the others will provided they are planted correctly in enriched soil and not as a component of a desert landscape surrounded by rock mulch.
The fruit is of good quality, however because of our intense lighting, it could become sunburned.
The surface mulching of the trees with wood mulch is crucial. You should water them like you would any other landscaping plant, fertilize them once a year, and prune them similarly to how you would most other fruit trees.
