How big do Bromeliads get?

Many people find themselves wondering: How big do bromeliads get? What’s the average bromeliad size? These flowering houseplants are slow-growing, and most of the time when you buy them from the nursery they’re already blooming. That means they’re fully mature and as big as they’re going to get. The blooms are one of the biggest selling points for bromeliads, so it’s rarely likely that you’ll purchase one that doesn’t have a flower, or isn’t at least close to producing a bloom.

That said, propagating the pups from your bromeliad is possible, and the size it reaches at maturity can differ from plant to plant. So, how big do bromeliads get?

How large will your bromeliad grow?

Throughout their life, houseplant bromeliads can grow anywhere from 1 inch to 3 feet tall. Some won’t reach the biggest height by maturity, but some will. It’s a toss-up when you’re growing pups for how big they will eventually get, but you should plan for a 2 to 3-foot-tall plant to be on the safe side.

A good indicator of how tall the pups may reach by maturity is the parent plant they stemmed from. If you bought a bromeliad on the taller side, you can assume that these new ones you’ve propagated will grow to a similar height because they’ll share similar genes. Of course, nothing is guaranteed, and the size your bromeliad grows too will also depend on if it receives the proper care throughout the course of its slow-growing life.

How to care for your growing bromeliad

Bromeliads are fairly simple plants to care for. They aren’t high-maintenance and don’t require anything special. One of the main differences between bromeliads and other plants is that you don’t put the water directly in the soil. Instead, you fill the water tank (or cup) of the plant at the base of the leaves. Once every week or so, you’ll want to change out the water that’s in the plant to avoid stagnant/stale water causing rot and collecting insects. If you’d like, you can also feed it with a fertilizer once a month during the growing season.

Similar to the variance in height of different bromeliads, you’ll find that different varieties of the plant may also prefer different lighting. Some prefer more shaded spaces, while others prefer bright, indirect light. The only sunlight you’ll want to fully avoid is direct. Direct light can cause damage to your plant, especially its leaves. If you notice your bromeliad isn’t thriving in one type of lighting, try switching to another for a brief period of time to see how it fares.

How long do bromeliads live?

The bromeliad that you’ll find most at nurseries and plant stores is the flowering guzmania. It’s the most common variety of bromeliad, and it leaves for two to three years with the right care. And since its blooms last for a significant amount of time once it matures, you’ll get to enjoy the plant at its best and brightest for a good portion of its life.

Although the bloom is beautiful, it does signal the plant’s end of its life cycle. The flower itself can survive up for a year if cared for properly, but once the bloom dies, you’ll know that your bromeliad is nearing its end. But the life of a bromeliad is a beautiful thing — post-bloom is when the pups begin to grow. The parent plant puts its remaining energy into the growth of new pups for propagation. Once the pups are roughly half the size of the parent plant, you can separate them, pot them, and continue your bromeliad collection.

Keeping your bromeliad safe from pests

Luckily, when grown in the home, bromeliads will suffer from less pests than their outdoor counterparts. An indoor environment is far from their natural predators, but that doesn’t mean they won’t ever become infested.

Mealybugs, aphids, and scale can cause damage to your bromeliad plant — but they aren’t naturally found inside. Most likely, if you have an infestation of any of these pests in your home, it’s because they were brought in on a plant that was infected. The best way to keep your bromeliad (and all your houseplants) safe from pests is to examine the new plants before you bring them home. And even then, it can be a good idea to keep the new ones separate from your other plants for three weeks, giving any potential eggs time to hatch. After three weeks if there are no pests, you can feel confident putting your new plant with your others.

The best defense against pests is a good offense. Be vigilant about examining new plants before bringing them into your home. Luckily, a healthy bromeliad can withstand a small infestation. So, if it does become infected, you have some time to solve the issue before it’s too late.

As you turn your home into a jungle, transform your bathroom into paradise with the help of hanging shower plants. Adding extra greenery to your bathroom can switch up the ambiance for a lush vibe — it’ll be like taking a shower in the great outdoors while enjoying the comforts of your home.

Curious about incorporating tropical vibes into this nook of your home? Read on to learn how to hang plants in the bathroom and which plants work best for this steamy environment.
Things to consider
Humidity and light
The bathroom is ideal for houseplants because of its humidity. However, keep in mind other requirements that your plants will need. Before you bring plants into your bathroom, consider factors such as light and temperature. If your bathroom doesn’t get a lot of light, invest in supplementary grow lights or pick plants that can thrive in low-light conditions. Also, take into account your bathroom temperature since some plants don't tolerate cold drafts.
How to hang the houseplants
Decide how you’ll hang your houseplants. Get creative with placement when building a plant paradise in the shower. Showerheads, caddies, shower rods, and curtain rods are great spots for hanging foliage, given that your planter isn’t too heavy. You can also take advantage of heavy-duty utility hooks that adhere to tiles.

How to propagate a golden pothos from cuttings
Hanging pothos plant

Golden pothos brighten up any home garden and they are one of the easiest plants to propagate in either water or soil. Pothos propagation can be done one of two ways -- either hydroponically or in soil. Try both options out to determine which one works best for your space. There are many different types of pothos plants, also known as pipremnum aureum or Devil's Ivy.

This guide for how to propagate pothos works for pretty much all of them. Golden pothos, one of the most common varieties, is characterized by its yellow undertones. It's important to note that leaves in a propagated golden pothos plant may contain less yellow spots than the parent plant. Though losing some color still leaves you with not one but two beautiful plants.
Why you might want to propagate a golden pothos
Whether it's a golden pothos or any other pothos variety, you'll soon find that these plants grow quickly. So even if you're not interested in creating more baby plants, cutting and pruning your pothos is vital to keeping it healthy and managing the amount of space it takes up. Your pothos might be hanging and reaching the floor, or it might be threatening to take over the wall you've been training it to vine over. Either way, cutting off a bit here and there will allow you to grow baby plants and will also encourage the plant to grow bushier and healthier vines.

Of the many popular flowers found in summer flower gardens, lilies are perhaps one of the most versatile. There is a range of colors, patterns, and even shapes available, so you're sure to find a lily that fits your garden. One popular lily variety is the stargazer lily, which has large, striking flowers. The petals of its blooms are pink with white edges and darker pink spots along the center of the petals. These stunning flowers are excellent centerpieces in summer gardens as well as indoor spaces. Here’s how to grow your own.
Indoor care
Stargazer lilies, like other lily varieties, can grow indoors with proper care. Indoor care for stargazer lilies begins with choosing the correct container. It needs to be deep and have sufficient drainage holes. Avoid shallow pots or those without drainage holes, such as ceramic pots. Likewise, you must use well-draining soil to avoid overwatering. Stargazer lilies enjoy moist soil, but they don’t tolerate standing water. Soil that is rich in organic matter is ideal.

Place your stargazer lily in your sunniest window, or where it can get light from a grow light if you don’t have access to a good window. Water your stargazer lily one to two times per week so the soil stays moist but not soggy. In the spring, freshen up the soil with a slow-release fertilizer to keep your lily healthy and blooming.
