Grammatophyllum Backbulbs - work in progress

[wetfeet101b]

Last year, I bought these two pretty Gramms.
One is a Grammatophyllum scriptum 'Phelps Farm' x Self and the other was a Grammatophyllum scriptum var. citrinum.

Due to my lack of knowledge about this genus, I somehow caused both plants to completely defoliate last winter and I ended up with two sets of naked pseudobulbs.

So I potted the pseudobulbs into smaller pots and used small orchid bark with a 1-inch layer of sphagnum moss on top.
From January to April, the backbulbs just sat there and I thought they were ready to throw in the towel.

However, this photo from June shows two tiny growths peeking from under the sphagnum moss. Those are 4-inch plastic and clay pots.
The var. citrinum is on the left, the 'Phelps Farm' clone is on the right.
At this time, the pseudobulbs still had no roots. I can literally pick them up from out of the pot and see no roots.


This is a picture from July, the var citrinum is at front-center, the 'Phelps Farm' is just behind it.


A few days ago, upon inspection it looks like the roots were starting to fill up the pots. So I decided to repot them into wood baskets.
The var citrinum had thinner roots and fit into a 4-inch wood basket. The 'Phelps Farm' clone has thicker roots and had two growths coming out so I planted it into an 8-inch wood basket.



These plants can sure grow roots! From no roots to full pot in just three months. These plants are starting to scare me.

Now I just need to make sure they don't drop their leaves in winter again.

Did you have the grams shipped from Florida? If so,I have been to there nursery.They were the ones that said it would be helpful to place reflective materials on my walls for my indoor areas.Good luck growing,Rich

Rich,

I did not get it from the original nursery. The online vendor that I bought it from, had a shipment from the "original" farm that they were reselling.
I wanted to purchase it from the original farm but the reseller's price was way lower. Go figure lol.

Nice comeback! I hope they do better for you this winter.

Nice comeback! I hope they do better for you this winter.

Thanks. I hope they do well this winter too.
The culture sheets state that they can take temperatures down to 45F.
My greenhouse never dipped below 55F last winter so I am not sure what caused the problems.

I am seeing pictures on the internet of mature scriptums with 10-20 spikes. I am just drooling!
