    Yes, you can harvest the seeds for propagation if you would like.

    Fertilize each plant with a handful of a 5-10-10 fertilizer in the spring at the time of planting or apply manure, compost, or a low nitrogen fertilizer to the soil surrounding the plants.

    These plants typically thrive in full sun but may tolerate partial shade. Generally, working in some compost or manure during planting should be sufficient enough as far as the fertilizing goes. The plant does need well-draining soil, so if the area is too wet, this could be your problem. I would either improve its drainage or move to a more sunny, less moist location.

    There is no clear answer to this. It is more of a personal preference. Generally, if the stalks are hard to cut or stringy when cut, then they are too far woody to be usable.

    Rhubarb is a fairly hardy and frost tolerant plant. If it is hit by a hard frost or freeze in late spring, it still can be eaten as long as the stalks are still firm and upright.

    It may be over-harvested. Over-harvested rhubarb is far more susceptible to pests and disease. You may need to let it sit for a year and not harvest to let it really establish so it is harder to over harvest it.

    But, for this immediate situation, it sounds like a fungus is attacking it after the harvest - so you can try treating it with a fungicide. Neem oil is a good choice as it is organic and safe for consumption.
