Being a friendly plant, the pinecone cactus is not considered toxic, it is safe for both humans and pets to have around. 

Additionally, the pinecone cactus does have a stunning variety called the paper spine cactus or Tephrocactus articulatus var. papyracanthus.   

Watering Needs 

When it comes to watering the pinecone plant, it's important to find the right balance. This cactus is native to arid regions, so it's adapted to survive in dry conditions. Water these low-growing cacti deeply. Overwatering can be a common mistake, so it's better to err on the side of underwatering. Make sure to not water them again until the soil is fully dried out. Besides, it is recommended to use containers with holes for drainage. 

During the growing season, which is typically spring and summer, you can water the pinecone cactus once every 2-3 weeks. Before watering, make sure the soil has completely dried out from the previous watering. It's important to avoid letting your Tephrocactus articulatus sit in water, as this can lead to root rot. 

In the winter months, when the cactus is in its dormant phase, you can reduce the watering frequency to once a month or even less. This allows the pinecone plant to rest and conserve energy during its dormant period. 

Light Requirements 

The pinecone cactus loves basking in the sunshine! This pinecone plant variety prefers to be kept in full sun to partial shade, so find a spot where it can soak up some rays. Place for 4-6 hours in bright sunlight or near a south-facing window for better results. 

Just make sure to avoid exposing it to direct, intense sunlight, as that can lead to sunburn. Remember, the pinecone cactus is like a sun-loving friend, but it still needs some shade to stay happy and healthy. 

Optimal Soil & Fertilizer Needs 

The pinecone cactus likes very airy, porous, nutrient-rich soil with a pH of 5.6- 6.7. Cacti require well-drained soil that dries completely between waterings. Your soil must have a sandy texture and a low water-holding capacity, just like desert soil.  Soggy wet soil can damage your cactus and contribute to bacterial and fungal rot. Ideally, you want to use our succulent soil or specialized cactus potting mix that contains 5 natural substrates and organic mycorrhizae to promote the development of a strong root system that helps your cactus to thrive. 

As for fertilizing, the pinecone cactus doesn't require frequent feeding. During the growing season, which is typically spring, you can use a balanced cactus fertilizer with an equal mix of about 5-10-5 (NPK). Apply the fertilizer once a year to provide the necessary nutrients for healthy growth. Just remember, less is more when it comes to fertilizing this pinecone plant! 

Hardiness Zone & More 

These pinecone plants belong to the hardiness zone of 8 to 10. Protect from extreme cold, as this species is frost sensitive and only hardy to 20°F for brief periods. In terms of temperature, the pinecone cactus prefers a warm and dry climate. It thrives in temperatures between 70°F to 90°F. It's important to protect it from extreme cold or frost, as prolonged exposure to freezing temperatures can damage or even kill the plant. 

When it comes to humidity, the pinecone cactus is well-suited to low-humidity environments. It can tolerate dry conditions, making it a great choice for arid regions. However, it's always a good idea to provide some occasional humidity by misting the plant or placing a tray of water nearby to mimic its natural habitat. 

Remember, creating a warm and dry environment with proper temperature and humidity levels will help your pinecone cactus thrive!
