This is a problem that is common to Hosta sieboldiana type plants that have yellow in their foliage. The classic example is Hosta sieboldiana 'Frances Williams' which seems very susceptible to this problem.

Spring desiccation, also called "Spring Burn", is a physiological disorder causes browning streaks to appear between the veins on the yellow areas of the leaf. It does not affect plants that are a solid green or blue-green color. It is not the result of a disease or insect infestation.

There is no treatment for this problem. Many of the yellow or otherwise variegated cultivars of Hosta sieboldiana do not suffer from Spring Desiccation. When growing the susceptible types, put them in sites that do not get direct sunlight especially in the early spring or in late afternoon in late summer to minimize the impact.
