Strelitzia Mandelas gold dry from the inside
Hello,
I send enthusiastic banana greetings from Berlin, Germany. In my strelitzia nursery with 130 plants more and more of the seedlings turn brown from the inside. It starts with a brown spot and then they dry down until the heart leave is dead. What could be the problem? Too dry or too wet? The plants are growing under artificial light in normal room temperature. They look healthy, but suddenly the weird dying process starts. I attached some photos in my gallery. Best wishes and thank you Stefan Banana Gallery - Member Profile |

Re: Strelitzia Mandelas gold dry from the inside
I usually water them after they got quite dry. Once a week maybe. As their roots are more like a succulent I don't keep them wet constantly. The roots of the dying ones are not rotten, but also not fully white.

Re: Strelitzia Mandelas gold dry from the inside
to dry way to dry. don't let them dry out. also mist your plants once, twice a day.

Re: Strelitzia Mandelas gold dry from the inside
As Beam already stated, mist the plants. The roots have not developed enough to support the plant. So misting & folar feeding is needed. Your greenhouse humidity should be about 60& (may be 70%) to keep the plants above the soil from drying out. A misting system with timer is needed.
Next: ... From a couple of the pictures it appears the plants may have been potted too deep. The soil is up to the first leaves on the stalk. ... The top of the corm/roots needs to be just below the soil so the roots can breath. Next: Also from the pictures, the potting soil looks to be too dense (???). This is difficult to judge from pictures, but needs to be said. What type of soil mix are you using? ... A 50/50% mix of commercial potting soil with added perlite should be about right for these plants. This is the key for the roots to breath and water to drain out of the pot. The pots need to drain to keep water fresh & not stale. Anyway at this stage of plant propagation & growth, expect some losses, due to human errors & weaker plants.

Re: Strelitzia Mandelas gold dry from the inside
Thanks a lot for your replies. This is very good advice. Especially concerning the density of the soil you might be right. I mixed regular soil with quite an amount of sand. As I collected the seeds in South Africa I thought it might imitate the soil well. But it is really heavy and gets very hard when it dries out. I'll try to find a way to repot them in maybe deeper pots and add more fluffy material like perlite. You said 50/50 ratio?
Thank you Stefan |

Re: Strelitzia Mandelas gold dry from the inside
Thats exactly how it is, yes. Dry as concrete on top, soggy wet at the bottom. I wonder how to do it now. Trying to take out as much of the old soil as possible without disturbing the roots too much? How would you do it? And what do you mean by soilless potting mix? Cocohum substrate or turf?

2. Since strelitzia regina grows well in both southern California and Hawaii, it is insensitive to watering and humidity. But, since it has fat roots, the roots will eventually compress the potting media therefore you should use a potting media that will retain air after the media is compressed. 3. What kind of fertilizer and artificial light are you using? Does the potting media contain dolomitic lime? |

Re: Strelitzia Mandelas gold dry from the inside
Dear Arusinzky,
thank you for your reply. 1. I'm not sure about that. But I will see in a couple of years. It is about 120 Strelitzia Reginae Mandelas Gold and about 20 Strelitzia juncea. 2. I'm about to change the potting medium. I already ordered new pots. 3. I use fertilizer very delicately. It is a regular fertilizer of good quality that works perfectly fine for all of my banana plants for years. The lamps also did a great job for all kind of plants for years. It is Osram 840 4000K. There is no dolomitic lime. Today I discovered new damaged plants. It is a bit worrying. It's 12 out of 140 now within a week. I though today if this is what 'burnt' leaves from fertilizer look like? Because it only affects the youngest leave. At the old ones roll slightly. I attached a new photo from tonight. Best Stefan |

Re: Strelitzia Mandelas gold dry from the inside
Thank you again. Interesting. I will keep you posted. 140 plants is quite a lot, to lose 1 out of 10 plants still fine. I think they require slightly acidic potting medium. Mine could be too basic due to high water hardness as well. The necrosis comes so quick, I couldn't figure out what may cause it.
Best wishes from Berlin! Stefan |

Re: Strelitzia Mandelas gold dry from the inside
Hello!
Just wanted to post an update. I replanted 155 Strelitzias in a new growing medium 50% turf and 50 % perlite. It planted them on the 23rd of December and after two weeks now they look really good. I'll keep you posted if interested. Best Stefan |
