Musella lasiocarpa need some help

milantropicallover · 03-03-2011, 04:37 PM

hello to everybody!
in this winter i grew up some musella seeds.
As you can see they are in trouble, i don't understand why, they are growing under grow light ( like a lot of other banana that are doing well) but they have kind of brown foliage even if i gave enough water, i don't understand, may be they are burning for the light but it seems akward 'cause they are growing thin with wery thiny foliage as there is not enough light.
Could someone help me?
thanks a lot and have a nice day!
bye

Consider these possibilities (since some of these issues were not included in your info):

Not warm enough for this variety, even if others are happy. My grown plant defoliates every winter, worse than any other banana I grow).

Too much water, or soil doesn't drain well enough, and roots are rotting.

Too much fertilizer.

Less light because it is crowded out by other plants which are taller.

Any signs of insects, fungus, mold, etc. Look really close at foliage, and inspect soil.

I haven't grown from seed, but all of these are conditions for successful plants, regardless of what the plant is - and even similar plants of the same genus can have wide variances in their requirements.

Maybe you should separate them into 2/3 groups and try different things on each group, and see what helps.

Looks like typical RSM (or similar) damage to me. Lasciocarpa seems very prone to it, much more so than my other bananas. Misting with water 3 times a day helps. However for the more stubborn problems, create a 50/50 mix of cooking oil and washing up liquid, put 15 m/l of this mixture into 1 litre of water and mix thoroughly. Spray the foliage with this paying attention to the underside of the leaves. Repeat twice a day. Keep the plants warm and ideally under light for 12 hours. That will kill off any beasties and allow the plants to recover.

I'm in agreement with the monkey. Red Spider Mite damage.
