What are tiny cacti called?

Mini cacti are called many different things. These smaller versions come in a wide range of colors, shapes, sizes, and varieties, so there isn't just one name for these cute plant babies. However, if you're wondering what the specific name is for the little cacti you have in your home, try taking a picture of it and identifying it through one of the many plant apps out there. You can even take a picture of it on an iPhone and scroll up to identify it with an image search.

How do you take care of a mini cactus?

Luckily, cacti all have about the same care requirements, so your mini cacti forest can be cared for in the same way as a full-sized cactus garden. Unfortunately, many people believe this makes cacti low maintenance.

At the end of the day, mini cacti often need more care than growers think, so it's best to educate yourself when you start your cacti collection so you can make sure they have what they need to thrive.

Watering

It's a misconception that cacti don't need to be watered. While your cactus might survive this treatment, it's not going to thrive. With that said, just a few steps can ensure that your cactus gets the right amount of water.

Step 1: Use a moisture meter or stick your finger into soil to determine how dry the soil is.

Step 2: If your soil is moist, leave it alone. If not, deeply water your cactus.

Step 3: Let the excess water drain out, then put the cactus back on its tray.

Lighting

Another misconception about cacti is they want bright direct sunlight all day. This again isn't the case, especially for mini cacti. These smaller cacti typically grow next to and in the shade of larger cacti or other desert plants, so they can't take as much intense light. You'll want to take a more measured approach when considering how much light your plant needs.

Step 1: Give your mini cactus about 4 hours of direct sunlight a day.

Step 2: Keep an eye on your plant's color. If you notice your cactus losing its color, that's probably a sign that it's getting too much sun. Give it shade or pull it away from your window.

Fertilizing

Cacti are low feeders and thrive on a balanced fertilizer applied twice a year during the growing season. Overfeeding can be devastating to a mini cactus, so make sure not to overdo it, especially during the winter.

Step 1: Fertilize your mini cactus once at the beginning of the growing season.

Step 2: Fertilize it again near the middle to end of the growing season. If you forget a feeding, the cactus will be fine until next season.

Temperature

Surprisingly, cacti are pretty hardy to temperature changes down to 45 degrees. However, they are susceptible to dramatic temperature dips, so keep this in mind as you find the right area for them.

Step 1: Find a warm, sunny area to set your mini cactus.

Step 2: Make sure your mini cactus isn't near a drafty window or door, a heating vent, or in a room without temperature control.

Toxicity

Eating a cactus won't harm cats, dogs, or humans, but getting past those sharp spines is the bigger problem. If you have little ones that might be tempted to touch a cactus, you'll want to be careful about where you place your mini cactus. The spines can not only hurt but can also become stuck in the skin and cause potential infections.

Step 1: Make sure your cactus is potted up firmly in a planter so it can't tip over.

Step 2: Put your plant in a place where pets and small humans can't reach it.

Do mini cacti get bigger?

Depending on the variety of mini cactus you have, it can, of course, grow bigger. However, most of these smaller varieties aren't going to grow to the same heights as the saguaros in Arizona. Your mini cactus might eventually get a few inches taller, but it's not likely that it'll grow into a giant size.

Collecting mini cacti is a fun hobby, especially since they're so small. There are so many different shapes, colors, sizes, and flowering varieties that you could end up with a mini forest of cacti in your home. Just be sure to provide them with good light and enough water while keeping them away from tiny hands and paws!

Palm trees evoke images of sunny beaches, warm days, and stress-free relaxation. You can bring a little of that into your home with a lovely indoors palm tree.

Parlor palm

The parlor palm is an excellent indoor palm. It’s mid-sized, with a mature height between two and six feet tall. It enjoys bright, indirect light, making it an excellent choice for rooms that are moderately well lit. It can tolerate some shade, but direct sunlight can result in sunburnt leaves. The parlor palm likes moderate watering, and is sensitive to overwatering, so make sure the soil is able to dry out between waterings.

How to start calla lily seeds and grow beautiful blooms
From sprouting to transplanting, here's your guide to growing calla lilies from seed
Hand touching calla bloom

Calla lilies are beautiful flowers that come in a variety of colors, including white, yellow, purple, and pink. The blooms rest on elegant trumpet-shaped stems, and when they’re spent, they leave behind seed pods. However, the seedlings are most often propagated through the bulbs instead of the seeds. Growing calla lilies from bulbs is fairly simple, but what if all you have are calla lily seeds? Luckily, growing calla lilies from seeds isn't terribly tricky, especially if you know what to do. This calla lily growing guide will explain everything you need to know to get started.
Where to get calla lily seeds

If you’re looking to grow calla lilies from seeds without an existing plant, you can always purchase seed pods from reputable catalogs, nurseries, or other growers. If you already have a calla lily, you can collect a mature seed pod from a spent flower. Calla lily seed pods each contain at least one or two seeds. Keep in mind that the seed pod itself can take a few months to mature, so you should leave it attached to the plant and wait to harvest it until after it’s matured.
