Leaves are getting very brown

Post by Ren_Kagome »

Greetings, fellow bamboo growers! I have about 20 little plants of bamboo that I started from a seed about 4 months ago. They aren't very big yet, but they are already growing new canes (wich is really fascinating to see, since I'm witnessing this for the first time of my life). I don't really know what species it could be exactly. However, there are 3 candidates: phyllostachys aureosulcata, phyllostachys arcana 'luteosulcata' and phyllostachys pubescens. Now, the problem here is that the leaves are kinda staring to get vey brown and dry. I've been watering them regurarly, so it can't be dehydration. I really don't know what to do. I don't want my plants to die. Any kind of help would be appreciated.
Here are some pictures:

What kind of light setup do you have? I've grown lots of bamboos from seeds, and one thing I've found is that if they are indoors and under less than ideal lighting conditions, there will not be enough energy to encourage roots to grow. Based on how those look, some of your roots may be rotting. Unless they are growing strong and bushed out, it's better to be very conservative with the watering. Sometimes over-watering may also be a cause of this, but if this is the case, putting them outdoors in partial shade, and getting them used to outdoor conditions may help them out, but I would advise on using larger pots as to prevent transpiration. If they can survive the transition, they will grow much faster, and healthier once there are a few good leaves. The best way is to simply start them from seed outdoors, and keep them used to it so there won't be a need to harden them off, similar to growing vegetables.

Other common deficiencies are a lack of calcium, and magnesium, which can be solved with epsom salts, but I believe it is more likely due the lack of outdoor conditions.

Here are moso seedlings 4-5 months old grown outdoors.
