Summer Wine® Ninebark

After back filling and lightly compacting the 50/50 mix of existing soil and compost give the Physocarpus Summer Wine a good deep watering. This is not to be rushed. Most of the water you put on the plant at first will run away from the plant until the soil is soaked. A general rule of thumb is to count to 5 for every one gallon of pot size. For example a one gallon pot would be watered until you count to 5 a three gallon pot would be 15 and so on. Check the plant daily for the first week or so and then every other day there after. Water using the counting method for the first few weeks. Gator bag Jr. can be used to help aid in this process and also provide plants with a good soaking due to the slow release of the water into the root-zone of the plant. Soaker Hoses can also be used to water when planting a long hedge.

Physocarpus such as Physocarpus Summer Wine grow best if they are fertilized once in the spring and once in the summer. Although some authorities recommend special fertilizer mixes to get the maximum results, Ninebarks do amazingly well with a more relaxed approach. Apply an early spring fertilizer with a product such as Espoma Tree-tone or Plant-tone at the recommended rate this will give the plant a boost of nitrogen that will be needed for healthy abundant foliage. Follow this up with a early summer application of Espoma Flower-tone, this will provide the necessary nutrients and raise the acid level in the soil which physocarpus favor. Espoma products are easy to use, just sprinkle around the base of the plant and water it in. Be careful with products such as miracle-grow as these products can burn newly planted plants when not used at the recommended rates. Slow-release fertilizer can help prevent rapid sucker growth that is vulnerable to diseases and insects. Either chemical fertilizers or organic matter can be used successfully. Since an organic method of applying manure and/or compost around the roots, produces excellent results and also improves the condition of the soil, this would be an excellent first line of attack. Organic additions to the soil can also be combined with a shot of chemical fertilizer for maximum effect. If chemical fertilizers are used on your Physocarpus Summer Wine, applying a slow-release, balanced fertilizer once a year is probably the simplest solution. There are many slow-release fertilizers on the market. If you can find a fertilizer formulated for shrubs and trees, this fertilizer would work well on Physocarpus. However, slow-release is certainly not the only way to fertilize ninebarks. A less expensive fast release fertilizer such as a 10-10-10 will work just as well if applied twice during the summer. If you are looking for a fertilizing routine tailored to your specific conditions, a soil sample should be taken and the fertilizer and trace elements matched to the needs of your soil. Don't fertilize Physocarpus Summer Wine after August. Fall is the time for Physocarpus to begin preparing for dormancy. Fertilizing at this time may stimulate new growth that will be too tender to withstand the winter. In the South, a late May application and another in July would be about right. More northern areas may wish to fertilize only once in June or July. The amount of chemical fertilizer used per plant will vary with the size of the plant and it's root system. Over-fertilization can be much more detrimental than under-fertilization. "Fertilizer burn" can occur when too much fertilizer is applied, resulting in a drying out of the roots and damage or even death of the Physocarpus. It is much, much better to err on the side of too little fertilizer than too much. When roots are burned, the first sign is often scorched looking leaves. If over-fertilization is severe, the plant may just wilt and die. If you are a beginner at growing plants Physocarpus Summer Wine is very easy to grow however it may be helpful to know that a very small plant which is planted in the ground will take about 1/8 - 1/4 cup of fertilizer. When fertilizing Physocarpus in pots, be careful to apply a fertilizer that will not burn the roots (such as a slow release or a liquid fertilizer). A very large shrub in the ground will take 2 - 3 cups spread around the drip line of the branches (not next to the trunk). This is a very loose estimate, so please read the directions on the fertilizer before applying it. If a liquid fertilizer is used for Physocarpus Summer Wine, it should be applied every month for both plants in pots and in the ground. Never fertilize a plant with a chemical fertilizer if the plant looks sick or wilted. If a plant is struggling due to a disease or root problems, the fertilizer will only add stress to it's life. Try to cure the problem before adding fertilizer. For an organic approach, many gardeners use commercial manure on the soil around ninebarks such as Physocarpus Summer Wine. Excellent results have been reported by visitors to this site after using composted manure. Commercial manure or compost can be applied yearly around the base of the Physocarpus Summer Wine. As with chemical fertilizers, do not apply it right next to the trunk or stems emerging from the ground.

We highly recommend that you mulch your Physocarpus Summer Wine with either a ground hardwood mulch or a ground cypress mulch depending on your local availability. Any type of mulch will do but cypress or hardwood mulch will be of a higher quality and provide better nutrition overall as they breakdown. Mulching helps to keep weeds away which will compete with your new investment for water and nutrients. A 2 to 3 inch layer of mulch is sufficient but remember to take care not to cover any part of the stem of the plant with mulch. Its better to leave a one inch gap of space between the mulch and the stem or trunk of the plant.

In general gardening terms, pruning is probably the most misunderstood gardening chore, and certainly, the chore that is most likely neglected. When we specifically look at pruning with regards to Physocarpus, this misunderstanding and negligence can be magnified. Pruning has been described as a “combination of art and science.” I find pruning to be one of the most relaxing yet rewarding chores in the garden. Pruning a specific plant to look a specific way, involves art in creating a unique definition for a specific plant, and it involves science in understanding the physical growing habits of the plant to be pruned. The most important reason for pruning Physocarpus Summer Wine is to improve the overall health of the plant which in turn will reward you with a plethora of blooms. Many times, Ninebarks that have not been pruned in a few years will develop dead or degenerative twigs. Removing the dead and dying limbs will minimize the possibility of diseases such as “dieback” and will also allow the plant to re-concentrate its energies and produce flowers. Another reason for pruning Physocarpus such as Physocarpus Summer Wine is to re-define the plant’s definition within the landscape. Many times, a plant may outgrow its intended size in the landscape, and must be pruned to re-define its purpose. Pruning should always be associated with re-invigorating a plant by allowing it to focus its energies on producing more vigorous branches, foliage, and flowers. Specific plant objectives require specific pruning techniques. If a Physocarpus is being trained as a hedge, it would need to be pruned differently than if it were being grown as a tree form. Screenings and hedges of Ninebark's would need to be pruned for their specific purpose within the landscape. It is also important to understand the specific growing characteristic of a certain Physocarpus when pruning that particular plant. When pruning established Ninebark's where no labeling is present on a variety to identify it, you need to look at the general growth patterns of the plant to be pruned. These observations should give you a good idea of how the plant tends to grow, and also how and when you should prune the plant.When pruning large Physocarpus, pruning can be a general shaping or shearing of the plants or it can be a severe pruning that significantly reduces the size of the plant. Many times, gardeners inherit a wealth of plants in their gardens when they purchase a previously owned residence. Although these plants may have been lovingly cared for by the previous owner, it may be necessary to severely prune these plants to restore vigor or to create a different definition in the landscape for the new owner of the property. If severe, pruning is necessary, it must be realized that the plant will shift its focus in the short-run from setting flower buds to growing vigorously, and it is very likely that the Physocarpus will have few if any bloom buds during the season following the major pruning. During the second season following the severe pruning, the plant should resume normal bud setting, and the plant should have healthier blooms because of the increased vigor in the plant. It is important to always use sharp tools when pruning Physocarpus or any plant for that matter. Knives, hand cutters, saws, and shears should be sharpened if necessary before pruning any plant. A sharp cut will heal quicker than a jagged cut, which will also minimize the likelihood of disease investing a cut during pruning. It is generally recommended to not use power equipment such as gas hedgers to prune Physocarpus as this does more harm than good. Pruning large Physocarpus like and older Physocarpus Summer Wine may be minor or major. Its general purpose is to maintain or restore vigor to the plant. Large Physocarpus that have been severely pruned have the advantage of a large root system that has excessive capacity, and its roots are capable of supplying all of its energies to a smaller number of branches and foliage. This enables the plant to increase its vigor, and become healthier. Pruning large Physocarpus that are well established will enable the plant to have continued vigor, and lead to many more years of supplying beauty to the landscape.
