- Toxicity: Contains calcium oxalate crystals – keep away from pets and children.
How to Care for Philodendron corsinianum
- Light Preferences: Thrives in filtered sunlight; avoid direct sun exposure to prevent leaf burn.
- Watering Routine: Prefers moist soil with high organic matter; allow the top inch of soil to dry out between waterings to prevent root rot.
- Humidity Needs: Benefits from moderate to high humidity levels; occasional misting can enhance growth.
- Temperature Range: Ideal between 18-27°C (65-80°F); avoid exposure to temperatures below 10°C (50°F).
- Soil and Growing Medium: Requires a well-draining, rich organic mix; incorporating peat, perlite, and orchid bark can be beneficial.
- Repotting and Container Choice: Repot every 1-2 years to accommodate growth and refresh soil nutrients.
- Fertilization: Feed monthly during the growing season with a balanced, diluted liquid fertilizer.
- Propagation: Can be propagated through stem cuttings; ensure each cutting has at least one node and healthy aerial roots.
- Pruning and Maintenance: Prune to maintain desired shape and encourage bushier growth; remove any yellowing or damaged leaves promptly.
Common Issues and Solutions
- Yellowing Leaves: May indicate overwatering; ensure soil dries out slightly between waterings and improve drainage if necessary.
- Leggy Growth: Often due to insufficient light; move to a location with brighter, indirect light.
- Pest Prevention: Susceptible to common houseplant pests like aphids and mealybugs; regular inspection and prompt treatment with insecticidal soap are recommended.
Additional Growing Insights
To encourage robust growth and larger foliage, provide a support structure such as a moss pole for the plant to climb. Regular pruning will help maintain a bushier appearance and prevent the plant from becoming too leggy.

Well Presented Concepts and Implementations (5th ed.)
Format: Paperback
Foreword: I have been running my own DNS servers on OpenBSD and FreeBSD for about 4 years. All of my previous DNS knowledge was obtained from the man pages and online tutorials.
The book is great because the example network used throughout the book is built upon, showing you how to "grow" your DNS with your expanding network. The design and implementation presented is priceless and covers some of my favorite topics: placement of slaves, hidden primaries, building root servers, split views, daisy-chaining, forwarders, partial-slaves, address maintenance issues, etc. The pros and cons of each setup are weighed and best practices are suggested. If you like a generous helping of diagrams, examples, and tables as a learning aid, you won't be disappointed.
One specific example of weighing the pros and the cons is presented on page 479 as follows:
"Could we have saved a few bucks on hardware by using our external authoritative nameservers as forwarders, too? Sure, but that would have presented a risk." After that statement, they proceed into all the details of "why."
There is adequate coverage on security. The authors preach defense in depth. An implementation example includes hiding your masters and only exposing bastion slaves. Securing communications between the masters and slaves is also covered in the security chapter using DNSSEC and TSIG. I think IPSec is another way to add a security layer, but that is probably another book.
After reading the book, I started to implement my new DNS infrastructure and found myself referring to the index often. It is fairly consummate, however, I found a few things missing, such as the $GENERATE statement. Also, some of the configuration details were lacking slightly. For example, the order in which ACL elements are processed and how negated elements affect the processing outcome. Another question I had was, what would happen if an ACL name is negated, and what if that ACL contained some negated elements. Well I found my answer by actually trying it and verifying with the canonical reference docs on isc.org.
I gave this book five stars because of its effectiveness in presenting the concepts and implementations of DNS using examples, good writing style, tables, and diagrams. If you're looking for the last 4 percent of the diminutive details of DNS, you will find it on isc.org.

Good DNS reference
Format: Paperback
The Book is a good reference for BIND9 DNS administration. Although, at this time, it's a bit outdated. It wasn't written to reference DNSSEC, or other new configurations.

Format: Paperback
Overall it was an OK book. I am already "competent" with DNS, specifically the BIND9 implementation but I got the book as reference material since the official documentation is a little sparse. The fifth edition (not sure about the others) even covers, albeit a little too briefly, how to deal with reverse lookup zones with subnet masks that do not fall on octet boundaries.

Thicker than I anticiapted
Format: Paperback
The encyclopedia of DNS books, meaning thicker than a phone book.
I like the fact that this book is thick but so easy to read and follow along with. If you know nothing about DNS, this book makes it easy to learn about DNS. It starts with the history of DNS and then explains the hierarchy of the DNS tree. A must read if you want to improve your understanding of the internet and what happens under the hood for name resolution.
