How to Grow Cactus Seeds: A Beginner’s Guide

If you’ve ever dreamed of growing your own cactus, you’re in luck! Growing cactus seeds is a fascinating and rewarding process, and we’re here to walk you through each step. So, let’s dive right in and embark on this exciting journey together!

1. Get Your Hands on Some Seeds

The very first step is to obtain cactus seeds, and luckily, there are a couple of ways you can do this. You have the option to purchase seeds online or from a nearby store, which offers a wide range of varieties to choose from. Alternatively, you can gather seeds from a healthy cactus either in your own home or from someone you know. Look for a pod on the flower-bearing parts of the cactus and gently collect the seeds, making sure to store them properly.

2. Prepare the Seeds for Planting

Now that you have your cactus seeds, it’s time to prepare them for planting. Different species of cactus have different-looking seeds, but as long as they come out of the pod easily, they’re good to go. Soak the seeds in water for a couple of days to ensure they’re fully primed for planting.

3. Set Up the Perfect Soil Environment

Cacti are unique plants that require well-draining soil to thrive. Start by purchasing a cactus mix from the store, and if it doesn’t already contain perlite and sand, adding some can further improve drainage. Before planting, place the soil in the oven for a few minutes to eliminate any unwanted pests or bacteria. If the packaging indicates that this step has already been taken, feel free to skip it. Fill a container with the prepared soil, water it thoroughly, sprinkle the seeds on top, and cover them with a thin layer of soil or sand. Place a clear wrap or lid on the container and keep it in indirect sunlight.

4. Be Patient for Germination

It’s important not to expose the seed mixture to bright, direct sunlight, as this can hinder germination. Now, it’s time to exercise your patience and wait for the seeds to sprout. This process typically takes a few weeks to a month, depending on the species. As you start to see small spines or sprouts emerging from the soil, it’s time to remove the cover for a few hours each day. Gradually increase the duration over time.

5. Water with Care

As you begin to uncover the seedlings, it’s crucial to establish a watering routine. Since the cover kept moisture locked in, you’ll need to provide hydration now. Start with small amounts of water and gradually increase the frequency, but make sure the soil has enough time to slightly dry out between waterings. Avoid overwatering, as cacti are susceptible to root rot.

6. Repotting Your Growing Cactus

Once your cactus has grown significantly (usually within a year), it’s time to repot it into a larger container. This provides ample space for the roots to grow and allows the cactus to access more nutrients from the soil. Carefully remove the cactus from its initial pot and replant it in fresh soil. Keep the newly potted cactus in the shade for a while, gradually introducing it to sunlight. Remember to water only when the soil is completely dry.


Should you soak cactus seeds before planting?

Yes, it’s recommended to soak cactus seeds before planting. The soaking time varies depending on the type of seeds you have, ranging from a few minutes to a few hours or even days.

How long do cactus seeds take to grow?

Cactus seeds usually take about a month to germinate. After germination, it can take several months to a year for the cactus to grow larger, depending on the species.

Can you grow cactus seeds in winter?

Growing cactus seeds in winter is possible if you can provide enough warmth indoors, such as using grow lights. However, it’s important to consider the specific temperature requirements of the cactus species you’re growing.

What is the easiest cactus to grow from seed?

One of the easiest cacti to grow from seed is the Echinopsis terscheckii, as it tends to grow quickly. Other straightforward options include Cereus, Mammillaria, Ferocactus, and Echinopsis.
