Foliage is often chlorotic. Trees are easily damaged by some herbicides and are susceptible to foot rot. In 1924, 'Thompson' was introduced by a local nursery and, being the first pigmented seedless grapefruit cultivar, became quite popular. However, other seedless cultivars with superior flesh and peel color were soon discovered and planted in favor of 'Thompson'. Fruit characteristics are essentially identical to 'Marsh' with the exception of the pink flesh color.
Fruit hold well on the tree, but flesh color fades as the season progresses.
