Do not buy small plants
The first thing to consider when buying winter hardy trees is the size of the plants. Small specimens are usually much cheaper, but are also much more susceptible. They do not have enough strength yet, the danger that they will take is great.
Pay attention to the correct planting time
Furthermore, you must observe the correct planting time. Although it usually means that you can always plant, except it is too dry and too hot, in young woody plants such as hibiscus , maple or beard flower , you better keep strictly to the planting in April and May.
