    Unfortunately, your photos did not come through. I am unable to say, for certain, what it is. There are a few causes, though.

    Fungi and salt buildup would the first thing suspected. Many fungi develop a relationship with plant roots, and are beneficial. If growth seems normal, and it isn't stressed outside of the weather, then this is not likely a cause for concern.

    If this is salt buildup, then flushing with quite a bit of water can help. To remove salt buildup from potted plant soil, rinse the plant's roots thoroughly under running water. Next, create a salt removal solution by mixing equal parts water and distilled white vinegar. Soak the roots in the solution for 15-20 minutes to dissolve any salt crystals. After soaking, rinse the roots again to remove any remaining salt. Finally, repot the plant in fresh well-draining soil and maintain proper care to prevent future salt buildup.

    They might still bloom. If the rhizomes are mushy just throw them out. If they are dry and shriveled they probably won't grow but it doesn't hurt to try. Here are planting tips:

    It is just like starting with a new, purchased rhizome. Bring them out of storage and plant them according to this article:

    You don't need to add the layer of pebbles in the bottom of the container. It won't help drainage.

    You got it! If you do not want them, you can remove the stem as close to the base as you can without cutting into the base. The quicker you remove flowering stalks after blooming the better. By this, I mean when you first notice the pod forming. You won't cause any harm to them, and may even make the foliage more full doing this.

    I would not cut off any more than 1/3 of the total leaves. This goes for most plants. You will want to supplement with a grow light. You will want to store them properly in the winter, as well. This article will offer more information on their care:

    It could be a fertility problem. Cannas need moist, rich soil and consistent fertilizing through the summer. If you aren't fertilizing, see if that helps. Here is how:
