Cork has been used for mounting orchids and bromeliads for years. Tillandsia airplants grow best when attached to cork bark. The uneven surface is perfect for finding just the right spot to attach them to. They will quickly root and become permanent. ​

I just returned from tens days in Portugal and spent several days in Alentejo, walking in some old cork oak forests. ​Alentejo is in south central Portugal and is where the majority of the cork trees are farmed. 

Get ready to change the labels on many of your plants, but don't remove the old name. You never know when that name may be resurrected. 

An ongoing study of Bromeliaceae, by a group of cooperating scientists, has lead to proposed new reclassifications for subfamily Tillandsiodeae. Using DNA sequencing, in combination with morphological characteristics, they determine which species have common ancestors. The authors are proposing further taxonomic splits to a number of genera to form monophyletic classifications.

Herb Plever, Editor of Bromeliana, has done an excellent job explaining all these changes. For more in-depth (and scientific) explanation, see Herb Plever's original article here in Bromeliana newsletter.

This year, the Conference of the Parties (CoP) to the Convention on International Trade in Endangered Species (CITES), concluded its 17th Conference on October 4th 2016, in Johannesburg, South Africa.

The CoP meets every two to three years to review the implementation of the Convention. During the two-week conference species are added or removed from Appendix listings. In 2013, three Tillandsia species were removed from CITES. ​

Have you ever wondered how and why plants are named? I stumbled upon this BBC Series - A Botany A Blooming History. This series "tells the story of how people came to understand the natural order of the plant world". This quest to discover how plants grow uncovered the secret life of plants on our planet.  

Part I of this series explains classification which is based on morphology and reproductive biology, and has existed for more than 300 years. All this is changing as a result of DNA sequencing. This video not only explains the history of traditional classification but also shows how DNA sequencing is explaining plant relationships.

This Summer has been one of the hottest yet!  And to top it off in California we are experiencing our  longest drought.  Sprinklers are reduced to 10 minutes per station, only 3 days per week.  All the lawns are starting to turn brown.  At the nursery we can continue to water, as we have always done our watering by hand and that is not restricted. 

We always use, and recommend using, the Fogg-It Nozzles.  They are available in 1, 2, and 4 gallons per minute.  We use the 2 GMP on seedlings and the 4 GMP on everything else.  The nozzles produce a heavy spray that feels like it's raining, which makes your tillandsias happy too!  They also add additional moisture in the air, which is beneficial during periods of low humidity. And these nozzles work great for watering large clumps and balls.  They have enough pressure to get the ball spinning so you are able to water all plants and all sides quite easily.

During the long Summer days, I recommend watering either very early in the morning or very late in the afternoon, just before sunset.  This allows the moisture to settle on the leaves for a longer period of time, thus allowing the water to pass into the leaf tissue.  If you water midday you are wasting water and time, as the plants will dry off long before any of the water has been absorbed.

If you are growing under shade cloth, one trick you can do on extremely hot days is wet the shade cloth as you are watering.  This will cool the temperature of the air as it is passing through the shade cloth, almost as if you have turned on an air conditioner.

Here are two short video showing how the Fogg-It nozzle "rains" on your plants.

Summer is a great time to have some fun photographing all the different flowers of your bromeliads.  I took these photos today during the "golden hour" when the light is perfect.  Using other plants as the background I let the natural light highlight the blur and create something different.  With all the different shapes and colors of the bromeliad flowers you can really be creative.  Practice doing this, all in camera, no tripod, flash or post processing.  Can you recognize and name these flowers? 

Tree gardening is an easy way to create a micro climate for your tillandsia collection.  If you live in a zone that will allow you to grow your tillandsias outside all year, then this may be for you.  This tree garden was created in Goleta, California by Ted Umbour.  He attached each tillandsia to a piece of cork bark and then secured the cork to the Jacaranda tree.  Cork makes a perfect host for most all tillandsias.  Cork is not prone to fungus and retains just enough moisture to encourage root growth.  No need to use any moss with the mounting, as that would keep the base of the plant too wet.  

The tillandsias are secured to the cork with a double strand of 20 gauge coated steel wire.  The wire is wrapped around the base of the plant and then twisted together on the back of the cork.  You will need to drill two holes in the cork to get the wire to the other side.  Twist and tighten the wire so the plant is held firmly.  Be careful that you do not damage the plant when tightening the wire.  Once attached to the tree the tillandsias are easy to water with a hose.  All the moisture that the tillandsia receive will add to the humidity in tree canopy.  The added benefit is that the plants will get plenty of dappled light and air movement, just as they would in their natural habitat.  Your tree garden will do better with more plants than with fewer.
