Ordinarily a bud stick will have 3 to 6 buds. Store the scionwood in a labeled plastic bag to prevent drying. Store in a cool area around degrees until needed. Scionwood should not be stored for more than a couple of days for late summer budding. When taking the scionwood to the field, caution should be used to keep buds from drying out. Keep buds in a cooler with ice to keep cool and moist. The T bud is one of the easiest manners of propagating.
This means the bark is easily peeled from the wood without tearing. Chip budding can be performed when the bark is tight so it can be used earlier and later in the season. With practice, the chip bud can be faster and quicker to heal. The basics in handling scionwood and rootstock are the same but the cuts are quite different with each method.
Specialty budding knives and suitable budding tapes can be obtained from horticultural or nursery suppliers accessible on the Internet or at some retail nurseries. Preparing Stock - A young seedling as large or larger in diameter as a pencil is pre ferable. Rem ove all the growth on the lower inches of the tree. Maki ng First Cut — The first cut is made lengthwise of the stem near the ground line, preferably on the north side of the stock.
Next, make the cross cut by a rolling movement of the knife, which lifts the corners of the bark where the two cuts cross each other. Cutting the Bud — Remove the bud from the stick by making the cut upward just underneath the bud.
Remove the Bud — Remove the bud from the bud stick by making a cut across the top through the bark and peel the bark and bud from the stick, leaving the wood attached to the stock. The bud may be held on the blade of the knife with the thumb on the leaf stub while it is being inserted in the stock. Insert Under Bark — Insert the bud in the flaps under the bark and push it down until it is firmly in place. Make at least two wraps below the bud and two above. The band maintains constant pressure, but expands with the growth of the tree.
For chip budding, a bud on a sliver of wood, complete with bark is inserted into a matching notch on the rootstock. Before you start, you need to choose a rootstock the plant you will be propagating onto.
Rootstocks can often be bought from rootstock growers and nurseries that specialise in the type of plant in question. Alternatively, they can be raised from seed or cuttings.
Choose a rootstock with desirable characteristics; such as a dwarfing habit that makes fruit trees more compact, or a rootstock that resists root diseases, or one that is easier to propagate than the scion top part of the budded tree. Remove these 'budsticks' from the parent plant so that they can be budded onto the rootstock.
Failure of buds to take usually results from not cutting accurately enough to get the cambium layers to match. Practise on spare shoots until a really good match can be reliably cut.
Some less experienced gardeners like to attach several buds as at least one should take. The RHS, horticultural colleges and others offer budding courses and these are strongly recommended. Knowing when to remove the bud ties can be difficult; the bud and the cambium must have united and this is indicated by swelling of the budded part of the stem.

Harlow Carr North Yorkshire. Hyde Hall Essex. Rosemoor Devon. Following these irrigation practices will enable buds to heal completely with no bud break before frost. Although budding rubbers and polyethylene tape reportedly decompose and need not be removed, studies show that unless they are taken off, binding or girdling of fast-growing plants like Bradford pear may occur within a month.
Summer buds should take in two to three weeks. On species budded in early summer, it may be desirable for the buds to break and grow during the same season. In this case, either remove the stock tops entirely or break them over within a few weeks of budding to encourage the scion buds to break. Once the buds have broken, completely remove the stock above the bud or keep a few leaves intact but remove the terminals, depending upon the species.
For dogwoods and other plants budded in late summer, remove the tops just before growth starts the following spring. A slanting cut away from the bud is preferred Figure If possible, set up stakes or other devices to insure that straight growth will occur before the buds break.
Straight shoots, however, are so essential to the growth of high-quality grafted and budded stock that stakes should be set as they are needed. To insure a top-quality plant, it is essential to remove unwanted sprouts. These sprouts should be "rubbed" off as soon as they are visible so that they do not reduce the growth and quality of the budded stock.
If they are removed regularly and early, large scars or "doglegs" can be avoided. Grafting and budding techniques combine the science and the art of horticulture. The scientific aspects include comparability, timing, disease and insect resistance, drought, tolerance, and hardiness.
Information on these topics may be found in have a broad working knowledge of a variety of texts and pamphlets. Acquiring practical skills in the art of grafting and budding, on the other hand, requires hours and even years of practice to perfect. Usually the careful supervision of a trained propagator is required for the serious student of budding and grafting to learn this art. From this publication it should be clear that many types of budding and grafting techniques are available.
Individual propagators usually have a broad working knowledge of all of these techniques but a high degree of skill in only two or three. These budding and grafting techniques can be used successfully, especially on a commercial basis, to propagate clonal plant materials.
In fact, perpetuating many of our horticultural clones depends on the successful application of these techniques. Knives Grafting and budding knives are designed specifically for these purposes and should not be used for carving and whittling wood. They are available in either left- or right-handed models. The blade is beveled on only one side, unlike conventional knives, which have blades that bevel on both sides down to the cutting edge.
Grafting and budding knives must be kept razor sharp so they will cut smoothly. Pruning and Lopping Shears Pruning and lopping shears should be the scissors or sliding blade type rather than the blade and anvil type. If used to harvest scion wood or budsticks, blade and anvil pruner will crush plant tissue. As with knives, pruning and lopping shears should be kept razor sharp to give clean, close cuts. Grafting Tools A special device known as a grafting tool has been designed for making the cleft graft.
It is used when the rootstock's diameter is greater than 1 inch. The wedge-shaped blade is used to split the stock, and the flat pick opens the cleft so that the scions can be inserted.
Once in place, the flat pick is removed and the cleft comes together to hold the scions in position. Wax Melter Wax melters are used to heat the wax for sealing graft and bud junctions.
They are usually made by modifying kerosene lanterns. The chimney is replaced by a small tin pot that serves as a receptacle for the wax. When the flame is kept low, the wax is melted without burning and can be kept at a suitable temperature. The specialized terms listed here are often used in discussing grafting and budding. The drawings in Figure 19 , Figure 20 , Figure 21 and Figure 22 will help in understanding these terms.
Adventitious buds - buds that can produce roots or shoots at an unusual location on the plant if environmental conditions are favorable. Bark - all tissues lying outward from the vascular cambium. Bud - an immature or embryonic shoot, flower, or inflorescence. Callus - undifferentiated parenchyma tissue formed at a wounded surface. Cambium - a thin layer of living cells between the xylem outer sapwood and phloem inner bark that is responsible for secondary growth.
Because cambium cells divide and make new cells, the cambia of two different but related plant will grow together if they are fixed and held firmly in contact. Compatible - plant parts scion and rootstock that are capable of forming a permanent union when grafted together. Double-worked plant - a plant that has been grafted twice, usually to overcome incompatibility between scion and rootstock; it consists of a rootstock, interstock, and scion. Graft - a finished plant that comes from joining a scion and a rootstock.
Graft or bud union - the junction between a scion or bud and its supporting rootstock. Grafting paint - A mixture used like warm grafting wax to cover wounds and prevent drying. It requires no heating before use and dries to a moisture-proof seal when exposed to air.
Unlike conventional paints, it does not damage plant tissue. Grafting strip - a rubber strip used to hold scions in place until knitting has occurred. Grafting strips are thicker and less pliable than budding rubber. Grafting twine - treated jute or raffia used to wrap graft junctions to keep scions in place and cambia properly aligned. Incompatible - plants whose parts will not form a permanent union when grafted together.
Used in cases where the scion and rootstock are not directly compatible with each other or where additional dwarfing and cold or disease resistance is desired. Parafilm - registered tradename for a nonsticky, self-adhering parafin film. Can be stretched over a bud or graft to hold the bud or scion in position as well as to seal the junction.
Used in place of a rubber strip or twine. Polarity - a condition where stems grow shoots at the apical or terminal end and roots at the basal end.
Raffia - One of several materials available for securing scions or buds to the rootstock, A natural fiber from the fronds of the raphia plam, raffia is one of the oldest materials in use. It should be graded for uniform size and length and moistened just before use to make it pliable. Rootstock - the portion of a grafted plant that has or will develop the root system onto which the scion is grafted.
Scion - a plant part that is grafted onto the interstock or the rootstock. The scion usually has two or more buds. Single-worked plant - a plant that has been grafted once; it consists of a rootstock and a scion. Standard - a single-stemmed understock used for the production of weeping forms of woody plants. One or more scions are usually grafted relatively high on the understock 2 to 6 feet. Top-worked plant - an established tree or mature plant whose upper portion has been removed back to the main limbs or trunk and then grafted with new scions.
Understock - same as rootstock. Union - the point where the scion and rootstock are joined. Warm grafting wax - a mixture, usually consisting or beeswax, resin, and tallow plus a fungicide, that is applied warm over a bud or graft junction to prevent drying and to serve as a topical dressing.
