Tree roots in containers may also die during summer if the soil temperature becomes too hot, exceeding air temperatures. Refresh the soil each spring by removing the loose, dry topsoil and replacing it with fresh, compost-enriched soil. Container-grown trees should be supplemented annually with slow-release fertilizer or use a liquid feed at regular intervals. They are more prone to drying out, therefore, container-grown trees need regular and thorough watering. This is widely available at nurseries and garden supply centers, or you can make your own using premium potting soil and amending it with compost, sand, and perlite.Ĭaring for a container-grown tree is different from a tree growing in the landscape. Regular soil may not drain well in containers and could be more prone to weeds, insects, and diseases. Do not use soil directly from the garden or surrounding landscape. Good container soil retains adequate levels of water without becoming waterlogged. The soil should maintain sufficient aeration and drainage while retaining suitable amounts of moisture. Soil is very important to the health of trees. Using the Right Soil for Your Container Tree Always check the bottoms of containers to ensure that there are ample drainage holes for excess water. ![]() Larger, heavier containers or planters can be used for trees that will remain as permanent fixtures year-round.ĭrainage is another important factor when choosing a container.Lightweight plastic pots are ideal if plants require moving or if they are located on balconies.Terracotta pots provide weight for stability but should be frost resistant.Clay pots are heavier than plastic, but are more stable in windy conditions, especially with larger trees.Not only is the weight of the container itself a factor, but take into account how much weight the soil, tree, and water will add to it, especially if the container will be used in areas such as balconies or rooftops, where structural weight capacity may be an issue. The overall weight of a container is important too, and this should be taken into consideration as well. Containers should also be as wide as they are high in order to provide the best possible insulation to the roots. Therefore, the mature size of the tree should be considered in order to choose a container with adequate space to accommodate both the growing tree and its roots. The container should be large enough to accommodate the tree. Containers should always complement their surroundings as well as the trees that are placed in them. Containers and planters for landscape trees are available in numerous styles, shapes, and colors. ![]() Trees can be planted in regular, moveable containers as well as in large, permanent planters. They are well suited to small spaces in the landscape such as patios and decks and can be used alongside other container-grown plantings as well. Container-grown trees can be used to frame entryways or to provide interesting focal points. If you have a porch, patio, or balcony, you can grow a tree in large container. You don’t need a large piece of property to grow a tree. Planting trees in containers is becoming more popular, especially in landscapes with little or no outside space.
