The fastest ways to remove a tree stump are by grinding it or burning it.

Stump grinding is often the quickest method, with professionals able to chip away a stump and its roots within a single session. You have the option to hire a professional stump removal service or rent a stump grinder to do it yourself. However, it's important to note that these machines can be large, difficult to transport, and dangerous to operate without prior experience. For safety reasons, hiring a local arborist or landscape specialist is often recommended.

Burning is another fast option. Before you begin, check your local burn laws. The process involves drilling holes into the stump, filling them with vegetable oil, and waiting 24 to 48 hours. Afterward, you can add charcoal bricks to the surface and light the fire, which must be attended at all times.

For a more affordable but much slower alternative, you can use potassium nitrate pellets to accelerate the natural decomposition process. This method typically takes four to six months.

Costs reflect the size of the tree or shrub, the complexity of the task, location accessibility, and disposal needs, and comprehensive quotes vary accordingly.

The best time to transplant a tree is when it is dormant. For many trees, this means either in the fall after the leaves have dropped (around October or November) or in early spring before new growth begins (around March). The ideal timing can depend on the type of tree. Deciduous trees do well when moved in early spring or fall, while evergreens are best transplanted in early spring or late summer. For example, pine trees are best moved in early fall, but maples prefer late fall. Avoid transplanting in winter, as the frozen or hard, cold soil poses a significant risk to the roots and prevents the tree from acclimating properly.

It depends. Smaller, younger trees take longer to mature, but they're more resilient, their roots don't get as damaged during transplanting, and they recover faster. Plus, they're much more affordable to plant, and it's possible to DIY the planting. 

On the other hand, mature trees produce fruit faster and provide more shade and privacy immediately. Ideally, a small or medium tree is the better choice if you can wait a few years for it to mature. But if you need immediate maturity, a larger tree is the only option.
