Amateur Gardencraft: A Book for the Home-Maker and Garden Lover

Since then I have never attempted to start my Dahlias in the house. I give them an extremely rich soil, spaded up to the depth of at least a foot and a half, and made so mellow that the new roots find it an easy matter to work their way through it. Water is applied freely during the season. I consider this an item of great importance, as I find that the plant fails to make satisfactory development when located in a dry place. A pailful of water a day is not too much to apply to each plant in a dry season.

The soil must be rich. In a poor soil development will be on a par with that of plants which have been given a dry place.

Because of the peculiar brittleness of the stalks of the Dahlia it is quite necessary to furnish them with good support. My plan is to set a stout stake by each plant, at planting-time. This should be at least five feet tall. I put it in place at the time of planting the tuber, because then I know just where the root of the future plant is, and can set the stake without injuring it. But if stake-setting is left until later in the season one runs a risk of breaking off some of the new tubers that have formed about the old one. I tie the main stalk of the plant to the stake with a strip of cloth instead of a string, as the latter will cut into the soft wood. Sometimes, if the plant sends up a good many stalks, it will be necessary to furnish additional support. Unless some kind of support is given we are likely to get up some morning after a heavy rain, or a sudden wind, and find our plants broken down, and in attempting to save them we are pretty sure to complete the wreck, as a slight twist or turn in the wrong direction will snap the stalk off at its junction with the root.

The Dahlia will be found one of our very best plants for use in the border where something is needed for a filler. It is very effective as a hedge, and can be used to great advantage to hide a fence. Single specimens are fine for prominent locations on the grounds about the house. In fact, it is a plant that can be made useful anywhere.

In fall, when our early frosts come, it will be necessary to protect it on cool nights, as it is extremely tender. This can be easily done by setting some stout sticks about the plant and covering it with a sheet. If tided over the frosty weather that usually comes for two or three nights about the middle of September, it will bloom profusely during the weeks of pleasant weather that almost always follow the early frosts, and then is when it will be enjoyed most.

When the frost has killed its stalks, it should be dug and got ready for winter. Lift the great mass of roots that will have grown from the little tuber planted at the beginning of the season, and do this without breaking them apart, if possible. Spread them out in the sun. At night cover with a blanket, and next day expose them to sunshine again. Do this for several days in succession until the soil that is lifted with them will crumble away easily. Exposure to sunshine has the effect of relieving them of a good deal of moisture which they contain in great quantity when first dug, and which ought to be got rid of, in a large degree, before they are stored in the cellar.

The tubers should never be placed on the cellar-bottom, because of the dampness that is generally found there. I spread mine out on shelves of wire netting, suspended four or five feet from the floor. If they show signs of mould I know they are too damp, and elevate the shelves still more, in order to get the tubers into a dryer stratum of air. If they seem to be shrivelling too much, I lower the shelves a little. Cellars differ so much that one can only tell where the right place is by experimenting. Watch your tubers carefully. A little neglect will often result in failure, as mould, once given a chance to secure a foothold, is rapid in its action, and your tubers may be beyond help before you discover that there is anything the matter with them. As soon as you find a mouldy root, throw it out. If left it will speedily communicate its disease to every plant with which it comes in contact. Some persons tell me that they succeed in wintering their Dahlia tubers best by packing them in boxes of perfectly dry sand. If this is done, be sure to elevate the box from the floor of the cellar.
