Four of the most common maladies of gardeners as observed by Dr. Hortfreud include:
Plant Lust. Gardeners are likely to come down with a bad case of plant lust any time they enter the garden of another gardener and see a lovely plant they do not have. Symptoms include a desire to linger in front of the plant for long periods of time, a run of questions about the plant, including "where can I get that" and an immediate feeling that they are deprived because they don't have that plant in their own gardens.
In extreme cases of Plant Lust, some gardeners attempt to remove seed pods or pinch off a tiny cutting in hopes of rooting it for their own garden. However, it should be noted that stolen seeds, cuttings or even plants will not grow in the thief's garden and so this will not cure Plant Lust.
Zone Envy. Zone Envy is similar to Plant Lust but affects gardeners when they visit a warmer climate zone than their own and see a plant that simply will not grow in the colder climate of their garden. There is no cure for gardeners as long as they remain in their own zone though some gardeners will attempt to cure Zone Envy by a process called Zone Pushing or Zone Denial. This involves seeking out the hardiest
Many gardeners with Zone Envy can be treated with constant reminders of the many plants, like peonies, they can grow in their colder climates that warmer climate gardeners can not grow.
Cart Eyes. Cart Eyes, another form of Plant Lust, occurs in gardeners when they are shopping at a garden center or greenhouse and notice a plant on another gardener's cart and immediately desire to have that particular plant or one just like it. The onslaught of Cart Eyes can be quite sudden and may cause a gardener to purchase a plant they previously had not noticed and have no idea where they will plant it once they take it home to their garden.
In rare cases, Cart Eyes can induce a gardener to attempt to distract the gardener with the plant they desire so they can swipe that plant from their cart or quickly switch it for another one, or at least have thoughts of doing so. When this happens, again, it is a fruitless attempt because a stolen plant never grows, even if the stolen plant was only in the cart of the other gardener, and not yet purchased.
63 and Sunny. This recently named malady affects gardeners when the weather conditions are perfect for gardening, as in 63F and sunny. It is worse when the preceding days were 45F and rainy and the 63F and sunny day occurs on a weekend. Once a gardener comes down with 63 and Sunny, it is best for everyone if they are allowed to cancel all other plans and spend the day in the garden.
Attempting to force the gardener to do other activities, especially indoors, when they've come down with a case of 63 and Sunny can result in mental harm to the gardener, with symptoms such as grumpiness, frowny face, and in some cases withering stares towards the person or thing that caused them to miss out on a day in the garden. Most cases of 63 and Sunny take place in early spring and late fall. It is rare in the heat of summer.
Though none of these maladies is life threatening, Dr. Hortfreud notes it is important to recognize their existence and treat them for the health and well-being of the gardener and all those around her.
