This page is intended to help increase survival rates and health of trees, particularly after planting, since trees often die from shock or neglect withing their first few years of life. When trees die, the release carbon back into the environment instead of sequestering more each year as growing trees are supposed to.
Trees are often happiest when they can grow naturally, but in some places with low biodiversity such as cities or arid regions, it is necessary to bring in new plants.
Many species of plant can be grown from cuttings. Start with a live plant, and cut close to the base of a branch. Depending on the species you may want to keep the cut end damp or fully submerged in water. Some dry-loving species like cactus or may prefer to dry out before they'll produce roots.
Some tree species will do well if planted a stakes into their new home, and will grow new leaves shortly after.
Some trees such as fruit trees can be grown from cuttings that are grafted to another plant which acts as the "root stock". One set of roots can host many different types of fruit and flower with less space than an entire orchard would use.
One problem with this method is that if the grafted portion of the plant dies back due to drought or freeze, then the root stock may grow back only branches from the root stock species, instead of the species which was grafted on.

Click the Trees button to learn about programs and organizations around the world offering free or cheap trees for planting projects. Some focus on small communities, schools, or farms, while others work internationally.
We generally encourage supporting your local tree growers financially, but this resource was created with the knowledge that not everyone has the funds to buy their own trees. You can also donate to some of the organizations or volunteer with them.
Research your tree species and guidelines for planting in your area. Some species are very hardy, and your climate may be mild enough that planting can be done any time of the year, but the best time for planting is often Spring through early Summer, or perhaps in the Autumn, especially where seasons are harsher.
If your area has a dry and wet season, planting will probably be most successful around the beginning of the rainy season, giving the plants time to get established before the dry weather sets in.
This method means that older trees can shelter younger trees, and that there will always been younger trees to replace older trees as they grow sick or old. This is also a good method if you are only just getting into tree planting and/or if you are working with a restricted budget. If trees in the first year die, then it gives you time to evaluate what went wrong, and find solutions such as alternative species, soil/hole amendments, improved watering, maybe providing protections via shade or fencing.
Starting with a smaller number of trees also lowers the risk of not getting around to planting them all in time, for example you may start digging only to find the ground is unexpectedly solid/compact.
There are several ways to space plants including trees.
For maximizing carbon absorption, and other benefits such as higher biodiversity, you can also crowd multiple tree species more tightly together than is typically suggested. When planted closer together, trees can easily fill in the space of one another when inevitable die offs happen during droughts, freezes, or other harmful events. Trees can also help shade one another from harsh sun and wind.
For shade trees you can plant them wide enough to let them grow to their full size with little to no room between.
If they are to be used for harvesting fruit, then you may want to plan for the full grown size of the tree, then add some extra room for people or machines to move between them.
Trees generally do best when you dig a hole bigger than the root ball, add some nutritious soil, or if they need additional drainage you may need to add sand, gravel, perlite or other amendments so to prevent root rot.
Dig the hole a little deeper and wider than the root ball, then take your shovel and stab at the bottom and edges of the hole to make the surface area uneven. If you don't do this, and the edges/bottom of the hole are too smooth, then this can create a bowl that holds water, and kills the plant during heavy rain or watering.
This changes for each species, so look up what type you are working will to see if they need to be planted exactly at the same level their soil is currently at, slightly below, or slightly above. Some plants won't mind too much if they are planted slightly off, but for many species the wrong depth can be deadly.
This can be accompanied by cardboard, mulch or other coverings to discourage grasses or vines from strangling new trees. The added space also creates a visual for landscapers to avoid hitting the trees with mowing equipment such as weed whackers, which can invite bugs and infections.
13:18 minute video about what to do vs what not to do when planting trees on grassland.
Water is life, and should be applied as soon as the planting is completed. Hold your plant gently, and use your boot to gently press down all the way around the base to compact the soil, and push out air pockets. Water all around the freshly dug area to complete this process and give the tree what it needs to start growing it's roots into the soil of it's new home.
This is critical for tree survival. You may be lucky enough to live in a place where very little watering is needed, but young trees are especially vulnerable to droughts and heat waves. Having a long-term plan can help reduce catastrophe after putting in the effort to plant and grow your trees.
One of our Native American contributor explained that cactus pads can be used around the base of a freshly planted tree to help seal in water, which is particularly helpful when working in hot, arid climates. The cactus pads have a long-lasting gel that holds water even as the cactus begins to break down, but that the cactus also works like a mulch which eventually breaks down and provides additional nutrition to the plant.
In addition to mulching, regular watering in important to help a tree survive the first few months and years in it's new home. Some people can use a watering can, communities might choose to use a truck to haul water to a tree planting site. If possible, installing a drip irrigation system can reduce work load, and supply water on a timer to ensure plants are not forgotten about (though it may be wise to turn off the timer/system during heavy rain events or seasons). Drip irrigation can be attached to a rain capture system or a greywater system.
Drip irrigation is better than traditional irrigation systems which can spray water very far, but often inaccurately (especially in wind or after the system is damaged), causing dry areas where water is needed, or even totally flooding areas that might not need any water at all. Drip irrigation is highly accurate, sending water directly to the roots of plants, and can even be hidden under mulch for a tidier look.
These are dug into the ground to help direct rain or melted snow towards areas that need water. They can help prevent flooding and agricultural run off from getting into waterways, while providing virtually free water for plants.
Swales are only appropriate for a certain range of slopes. Too shallow and the water won't flow, too steep, and the swales can make the hillside unstable.
How to Reforest a Steep Slope Without Swales or Irrigation
12:35 minute video shows how native grasses can be planted in lines or curves to help slow down water enough to help it penetrate a hillside slope without disrupting the soil integrity.
The lady explains her choices of native tree species interplanted within the native grass, how the evergreens provide shade and protection to the rainforest species. She explains how the grasses help protect her saplings from freezing and baking hot weather. However she comes along periodically to weed away vines and grasses to prevent them from strangling the saplings, then uses the weeded materials as free mulch to further lock in moisture.
This example is in Australia so she also explains how the different species will support local natives including koalas.
All plants need nutrients, but a feeding at the same time or right after planting can shock the plant. It is generally best to wait a few weeks, and start with a smaller amount of nutrients than established plants would require.
Mulch should be applied right away after planting, and should be reapplied as needed (often 2+ times per year) to help maintain soil moisture, but also to break down and improve soil quality.
Mulch can be bought from a supplier, or even for free from apps like Chip Drop, but you can also make your own by chopping up plant matter and spreading it around the base of your plants, for example any un-diseased branches or twigs removed during trimming or pruning. Never use infected plant materials, as this can reintroduce insects, fungi, and viruses back into the garden.
Plants generally do best with fairly frequent feeding during the growing season. This can be solid or liquid, but all fertilizer types should be applied during dry weather to avoid rain water from washing nutrient run off into waterways.
Apply around the drip line, as this is the best place for roots to absorb the nutrients. The drip line is generally around the outer reaches of the leaves above, where rain water rolls off the leaves, and lands above the outer reaches of the roots beneath the soil. As the plant grows, the drip line will expand outward. Some species collect water with their leaves, and lets the liquid roll down towards the center of the plant. Their roots will be concentrates closer to the center of the plant.
Pruning is an important method for keeping plants healthy. It can reduce the weight of branches, reduce how much nutrients the plant needs to split up among too many limbs which can reduce fruit quality, or cause imbalance which can cause the tree to topple or break limbs. Pruning can also allow better light and rain infiltration. Gardeners can also use pruning time as an opportunity to check the health of the plant, remove any sick or dead limbs, suckers, or simply to reshape the plant into a more aesthetic shape.
Large animals including deer, elephants, and livestock can do serious damage to trees before they have a chance to grow, so you may have to start your project with protective fencing, which may later be removed once the plants are an appropriate size.
When planted along the edges of fields, trees and bushes can help act as wind breaks, which reduces erosion, provides shade for livestock and crops. The plants also act as cover for beneficial species including insects and birds who then help control pest species, reducing or eliminating the need for pesticides. The reduced erosion from wind and water, means more nutrients stay in fields, also reducing costs.
Hedgerows have historically been used throughout Europe to divide farm land, and keep in livestock, but they are also vital corridors for wildlife.
Trees can be a huge help on farms when planted as shade trees in fields. These shade trees take up minimal space, but provide important resting spots for migratory birds, and can improve crop yields. This method has significantly improved life for African Farmers, reducing irrigation requirements, while providing additional firewood and other resources.
"Crofting is a unique social system, based on small agricultural holdings. It is integral to the cultural and economic life of the Highlands and Islands. There are over 21,000 crofts covering 750,000ha of land. This equates to over 15% of the land mass of the UK.
Native woodland in the crofting counties is fragmented and under pressure. Nonetheless, it includes some of the richest woodland habitats in the UK, such as the temperate rainforests of the western seaboard – Scotland’s rainforest." - Woodland Trust: Croft Woodlands
"Planting trees on crofts can strengthen this fragile woodland network, while delivering multiple benefits for the crofter and the wider public, including improved productivity, business diversification, carbon capture and richer habitats.
There is, however, little tradition of tree planting or woodland management in crofting. Until the 1991 Crofter Forestry Act, woodland ownership and management rights were reserved for landowners, not their crofting tenants." - Woodland Trust: Croft Woodlands
These tightly packed native tree plantings use a variety of species which can help support one another. Using round fencing seems to deter deer and allow strong winds to move around the trees, rather than mowing them down. When the trees are big enough, they no longer need the protective fence, and help to rebuild healthy soil on the farmland.

PHS: Tree Tenders Program "works with volunteer-based community groups to plant trees. The program provides workshops in tree planting and care and volunteer group organization. PHS has trained more than 6,500 people who have gone on to lead volunteers in planting over 3,000 trees each year.
PHS’s Watersheds program provides funding and technical support to watershed management non-profits. Through this program, dozens of such watershed restoration projects are conducted throughout the region. This results in thousands of trees planted in those sensitive water protection zones every year.
Yet, the Greater Philadelphia region still needs more trees. While a “good” tree canopy coverage (the area of land shaded by trees) is considered to be 30% of land area, the city of Philadelphia only has 20% coverage and as little as 2.5% in some neighborhoods.
PHS is committed to increasing the canopy, especially in neighborhoods with few trees and high average temperatures. Throughout the year, PHS works with more than 100 community groups to plant and care for trees in the Philadelphia region. Help PHS partner with community members and plant more trees in your neighborhood."
