Edema

Under certain conditions plants in greenhouses or even in the open field, may absorb water through the roots faster than it can be transpired through the leaves, with the result that dropsical swellings or blisters occur on the leaves and more succulent stems. There is also a deformation of the foliage, much like the leaf-curl produced by over-feeding. This trouble, known as edema, occurs when the soil is warmer than the air, or during periods of moist, warm, cloudy weather, which checks transpiration. The grower should cease pruning, and withhold water, and in the field cultivate deeply. In the greenhouse, adequate ventilation should be given, keeping the house dry rather than moist.

  1. Hello Everyone at Tomato Gardener!

    I have to start out by telling you how much I love your site! I want to introduce myself.....My name is Ben Fairfield and I am one of the founders of The Urban Garden Project™. The Urban Garden Project™ is the initiative to encourage Americans to learn from history, become more self-reliant, save a significant amount of money, and eat healthier, all as a result of planting their own urban garden! The goal of The Urban Garden Project™ is to encourage and catalogue the creation of 100,000 urban gardens by 2020. We know that this is a sizeable goal, but we will accomplish it 1 garden at a time!

    As a result of your successful blog and your obvious passion for gardening I was hoping that you would visit our website at www.urbangardenproject.wordpress.com to learn more about the project. It costs nothing to support the project; we simply need help getting the word out to the world so that we can begin to catalog existing or new urban gardens. It would also be great to be able to add you to our garden catalog and link to your site through our blogroll! The official kick off for the project is April 1st 2009 and we are busy creating videos, tutorials, product reviews and more to make visiting worth everyone’s time!

    I am hoping that as a result of our shared passion for gardening you can help us in spreading the word about The Urban Garden Project™. Again, your support costs nothing. Our mission is pure and we hope that you can come along side us in this project to grow the gardening community and the number of urban gardens!

    Thank you so much for your time and we are looking forward to you visiting our site and letting us add your garden to our growing catalog of gardens from across the world!

    Have a great day!

    Ben Fairfield
