Key is to regularly water newly-planted trees, at least bimonthly for two months. It is also important to ensure you choose a location where your tree has enough space, which you can calculate from a variety's eventual height and spread.
Bare root & containerised trees have different planting requirements. With bare root, it is important to soak your tree's roots in water for up to 2 hours before planting, while with containerised trees it is important to drench your tree's rootball. With bare root it can be useful to prune woody roots back a few inches, while with containerised trees, it is important to free any spiralized roots growing around the rootball's circumference. With bare root trees, dig a hole so as to ensure the graft point is above the soil, while with containerised trees, ensure the pot sits no lower than an inch below ground.
Bare root & containerised trees also share planting requirements. Dig a hole twice the radius of the rootball. Stake your tree no more than 2-3 inches from the stem, pointing away from the prevailing wind. Fill the hole with a mix of compost and garden soil, and add fertiliser and mycorrhizal fungi. Do not compress the soil. Give your tree a good watering. Add mulch on top whether bark and wood chippings, compost, manure, leaf-mould and stones. Make sure mulch doesn't touch the stem. Tie the stake to your tree, leaving space for growth. Place a rabbit guard around your tree.
Apply fertiliser and replace decomposed mulch come spring. Check ties to ensure there is no rubbing. Collect fallen leaves in autumn.
Magnolia trees are easy to grow. Your tree’s growth and output will likely be fine providing you followed our planting and care instructions. Below we address some common queries:
- Hardiness: While magnolia trees originate from the North America and South/East Asia, the varieties Primrose stock have been specially bred, primarily in France and United States, for colder climates and are fully hardy in the UK's climate.
- Position: Magnolia trees benefit from being planted in full sun. Planting your tree in a sheltered spot will allow the tree to put more resources into flowering.
- Soil Types: Soil types are best ignored and remain an unwelcome confusion. Every plant will adapt to its conditions. Having said that, less than ideal conditions will reduce growth. Waterlogged soils will starve your tree of oxygen, which plays a key role in photosynthesis, cause its roots to rot and create the perfect environment for many diseases. Similarly, compressed soils can starve a tree of oxygen and water, so do not compress the soil when planting. Aeration can be improved further with mulching.
