How to Grow Golden Barrel Cactus

If you love plants, you’ll definitely love the golden barrel cactus. Also known as Echinocactus grusonii, these round plants are endangered in the wild but make popular staples in households with their beautiful yellow flowers. We’re here to teach you how to grow your own golden barrel cactus at home. Read on to learn about everything you’ll need to care for your cacti properly.

[Edit]Steps

[Edit]Planting Cactus Seeds

1. Get golden barrel cactus seeds. Order the seeds online or visit your local gardening store.
   
2. Plant the seeds in a seed tray. Use a potting mixture of half sand and half peat moss or potting soil. Fill up each compartment of the seed tray halfway with the potting mixture and then place a few seeds in each compartment. Cover the seeds with a layer of the potting mixture.^[1]
   
3. Put the tray of seeds in filtered sunlight. Filtered sunlight is just non-direct sunlight, so any bright area will work.^[2]
   
4. Check on the seeds daily to make sure the soil doesn’t dry out. Lightly water the seeds to keep the soil moist.^[3]
   
5. Wait 2 to 6 weeks for the cactus seeds to germinate. The seeds will look like red spheres once they’re germinated.^[4]
   
6. Transfer the tiny cacti to 2 inch (5 cm) pots once they develop spines. Spines are the sharp, prickly parts of the cactus. Use tweezers to help with the transferring process. Plant the cacti in the same soil mixture you planted the seeds in. Wait one week to water the cacti after transferring them.^[5]
   
7. Let the cacti grow for 1 to 2 years before re-potting them. After that time, re-pot the cacti in pots that are one size larger than the pots they’re currently in. Gently pull the cacti out of their old pots and place them in their new pots, packing a soil mixture into the extra space around the roots. Water the re-potted cacti whenever the soil is dry, about once a week.^[6]
   
   • Always wear thick leather gloves when re-potting a cactus to protect yourself from the spines.^[7]
8. Choose whether you want your cacti to be indoor or outdoor plants. Now that the cacti are mature, you can plant them in soil outside, or leave them in pots indoors. There are a few things to keep in mind when you’re deciding:
   
   • The golden barrel cactus will only survive mild winters. If you live in a region with harsh winters, you should plant your cacti indoors.^[8]
   • Most golden barrel cacti won’t flower if kept indoors. If you want your cacti to produce the signature yellow flowers, plant them outdoors.^[9]

[Edit]Transplanting Your Cacti Outside

1. Plant your cacti in a spot that gets a lot of direct sunlight. A spot that receives full sunlight all day long is ideal unless you live in an area with extremely hot temperatures. In that case, plant your cacti in a spot that gets half direct sunlight and half shade throughout the day.^[10]
   
2. Dig shallow holes so the spiny parts of the cacti are fully above ground. Only the roots of the cacti should fit in the holes. Use your hands or a small shovel to dig the holes.^[11]
   
3. Remove the cacti from their pots and loosen the soil around the roots. Use your fingers to rub off some soil from the sides and bottom of the roots. This will help the roots grow into the soil in the ground. Make sure you’re wearing thick leather gloves when you’re handling the cacti.^[12]
   
4. Plant the cacti in the holes. Make sure they’re not leaning to one side or they will continue to grow that way. Fill in the holes with the soil you dug up, packing down the soil around each cactus so it’s firm.^[13]
   

[Edit]Caring for Your Cacti

1. Keep your cacti in direct sunlight. For indoor cacti, keep them near a window where they will receive direct sunlight from outside. For outdoor cacti, plant them in an area where there is full sun.^[14]
   
2. Keep your cacti in an area that is room-temperature if they're indoors. Room-temperature will be fine until winter arrives, when you’ll need to give your cacti a “resting period.” During winter keep your cacti in an area that is around 50 degrees Fahrenheit (10 degrees Celsius). Do not expose your cacti to temperatures below 41 degrees Fahrenheit (5 degrees Celsius) or above 70 degrees Fahrenheit (12 degrees Celsius) during the resting period.^[15]
   
3. Water your cacti whenever the soil gets dry, about once a week. This goes for both indoor and outdoor cacti. During the winter, water them less, about twice a month. This will prevent the roots from rotting.^[16]
   
   • Avoid wetting the bodies of your cacti when they're in direct sunlight to prevent sunburn. Water the soil surrounding your cacti instead.^[17]
4. Add a fertilizer to your indoor and outdoor cacti every 4 weeks.^[18] Your cacti needs fertilizer in the summer. Use a high-potassium fertilizer to help your cacti grow faster and encourage flower growth. Look for a slow-release fertilizer at your local gardening store.^[19]
   
5. Re-pot your indoor cacti once every 2 to 3 years.^[20] Plant them in pots that are one size larger than the pot they’re currently in.
   
   • Re-pot your cacti using a soil mixture that is one third coarse sand. This will make the potting mixture more porous.^[21]
6. Be patient with your cacti. The golden barrel cactus grows rapidly during the first couple of years after being planted, but it starts to slow down after that. It could take over a decade for your cacti to reach full size (some golden barrel cacti grow to be 3 feet (91.4 cm) wide!) so be prepared to tend to your new cacti for a long time.^[22]
