The best time to plant mature trees is generally during their dormant season, which is autumn in most temperate climates. This is because the tree’s energy is focused on root growth, rather than leaf and flower production. Cooler temperatures and moist soil conditions also help to reduce stress on the tree during this critical establishment period.

Here’s a more detailed breakdown of why autumn is the ideal time for planting mature trees:
Cooler temperatures: The cooler temperatures in autumn help to reduce stress on the tree as it establishes its new root system. Hot summer weather can be very challenging for newly planted trees, making them more susceptible to transplant shock.
Moist soil: Autumn rain typically helps keep the soil moist which is essential for root growth. Dry conditions can make it difficult for trees to establish themselves.
Less chance of heat stress: The absence of scorching summer sun reduces the risk of heat stress on the newly planted tree.
Dormancy: Trees are naturally dormant in autumn, therefore they are less likely to be stressed by the transplanting process. During dormancy, the tree’s energy is focused on root growth, rather than leaf and flower production.
However, there are some exceptions to this general rule. For example, evergreen trees can be planted in late winter or early spring, as long as the ground is not frozen.

Choosing the right tree for your garden depends on several factors, including the size of your garden, the amount of sunlight it gets, and the type of soil you have. Here are a few things to consider:

• The size of your garden: If you have a small garden, you’ll want to choose a tree that will mature to a relatively small size. Some good options for small gardens include crabapple trees, dogwood trees, and redbud trees.
• The amount of sunlight your garden gets: If your garden gets full sun, you’ll want to choose a tree that can tolerate hot and dry conditions. Some good options for full-sun gardens include oak, ash, and maple trees.
• The type of soil you have: If you have clay soil, you’ll want to choose a tree that can tolerate wet conditions. Some good options for clay soil include willow trees, poplar trees, and bald cypress trees.

The best time to prune mature trees depends on the specific species and the reason for pruning. Here’s a breakdown of the key factors to consider:

• Season:
  • Generally: Most routine pruning for mature trees is done during their dormant season, which is typically in late autumn or winter. This allows the tree to focus its energy on healing the pruning wounds before the new growing season begins in spring.
  • Exceptions: Some tree species like birch, maple, and walnut bleed sap heavily if pruned in early spring. For these, wait until late summer when sap flow has slowed down. On the other hand, some evergreens like Holly benefit from spring pruning.

• Reason for Pruning:
  
  • Dead, diseased, or damaged branches: These can be removed anytime throughout the year, as the health of the tree is the priority.
  • Shaping or size control: For these purposes, pruning during the dormant season is ideal.
  • Flowering trees: Prune right after they finish flowering to avoid removing flower buds for the next season.

Remember, for major pruning jobs on mature trees, it’s always best to consult with a certified horticulturist. We can assess the specific needs of your tree and recommend the best pruning practices to ensure its health and beauty.
