Mystery Cactus [large]

Highlights

Mystery Cactus: Cacti capture the sublime beauty of the desert and they grow in an enormous array of forms. These charming, prickly plants also produce showy, colorful blooms. They're also wonderfully low maintenance. This cactus is fully rooted in a 3.5" plastic pot.

Please Note: Mystery succulents arrive unlabeled. We cannot take specific variety requests or provide IDs after purchase. Ordering multiples may result in repeats.

This cactus variety will not survive a hard frost, but if there is a risk of freezing temperatures it can be brought indoors to grow on a sunny window sill or under a grow light. Cactus need bright sunlight, great drainage, and infrequent water to prevent rot. Pick containers with drainage holes and use well-draining cactus and succulent soil with 70% to 80% mineral grit such as coarse sand, pumice, or perlite. Water deeply and wait for the soil to completely dry out before watering again.

WHAT TO LOOK FOR IN A GROW LIGHT

Light Output

• Lumens are the main measure of light output or brightness you should consider. Our eyes are not very objective when it comes to measuring brightness, so it's important to read a grow light's specifications before purchase.
• Select a grow light that provides 300 - 800 lumens per square foot.

They will if they're shipped with this Heat Pack. You can order just one and we'll include as many as necessary for your particular shipment. We recommend getting one if you expect high temperatures to dip below 40 degrees or low temperatures to dip below 25 degrees at any time in the next week. Plants tagged as [houseplants] in their title ship separately and automatically get free heat packs added when necessary.

What succulents can I plant outdoors in Phoenix AZ? See answer

I'm trying to create a succulent garden outside, but I live in the Phoenix AZ area. I'm not sure which plants will survive in the middle of summer. Please help me! I don't want to create a beautiful garden for them just to die in summer.

They're going to be in direct sunlight most of the day. Which it's not bad right now, but as I'm sure you know. It can get up to 120 degrees out here.

So any help will be helpful.

Thanks See more »

Cactus, Agave, Aloe and most Crassula are going to be your work horses for this garden. They're beautiful plants and can survive in harsh sun and heat. However, due to spines or mild toxins, these plants don't tend to make good walk way plants. If your garden has a path running through it, you may want to plant these away from that path.

Some varieties that would work well near a path or an edge to your garden are Graptopetalum paraguaynse, Sedum rubrotinctum, and Portulacaria as they're more safe.

These are likely fungus gnats and they can be a real nuisance, but there are a few ways you can go about dealing with them. Please note, the best strategies for exterminating them deal with both the flying adults and the larval worms that live in the soil, so be sure to employ multiple treatments to ensure success.

1) Sticky traps. Grab a yellow index card and smear some honey or thick corn syrup over both surfaces. Suspend this card an inch above the soil your plant is in. The yellow color and sugary smell will attract the flying adults which will get stuck to the card (growing a carnivorous plant, like a sundew, near the infested plant will work as well).

2) 1.5% hydrogen peroxide. Buy hydrogen peroxide from any store where first aid supplies are sold. Usually, it's sold as 3% hydrogen peroxide. Then mix it in a 1:1 ratio with water, giving you 1.5% hydrogen peroxide. Water with this mixture instead of plain water. This will kill the soil dwelling larva. Be warned, hydrogen peroxide will turn into water and oxygen rapidly, in the presence of sunlight. Please keep this mixture out of sunlight until you… See full answer »

If you mix one part potting soil with two parts mineral grit (coarse sand or pearlite will do nicely), that makes for an excellent succulent soil! We have a video on making succulent soil that you might be interested in. Check it out at the link below!

How do I use bone meal as a fertilizer? See answer

Organic fertilizers for succulents See more »

3 years ago  •  Staff Answer

Honestly? Bone meal isn't the best option when it comes to succulent fertilizer. Not only do succulents require very little fertilizer, they like a balanced fertilizer. A "balanced" fertilizer is one where the ratio of nitrogen, potassium and phosphorous are roughly equal (this ratio is commonly called an NPK ratio).

Bone meal, unfortunately, is both strong and unbalanced. To put its strength into perspective, when fertilizing a garden with bone meal, you use roughly 1 tablespoon of it for every 2 square feet of soil. It's powerful stuff! Also, bone meal has an NPK ratio of roughly 3-15-0, which means that for every 3 parts of nitrogen in the bone meal, there's 15 parts phosphorous. There's also no potassium in bone meal.

If you really want to use bone meal on outdoor succulent beds, first test your soil and see if it's low in phosphorous. Then, test the pH of the soil and make sure it is below 7. If the pH is above 7, you'll have to amend the soil to lower its pH because bone meal is ineffective in alkaline soil. If you find that your soil is both phosphorous poor and has a pH below 7, go ahead and sprinkle 1 tablespoon of the bone meal over your soil for every 2 feet of… See full answer »
