Is it too late to plant tree saplings in Zone 7?

Zone 7 includes areas with minimum temperatures that range from 0°F (-17.8°C) to 10°F (-12.2°C), and maximum temperatures that reach up to 100°F (37.8°C). Generally, planting saplings in this zone is best done in spring or fall, but is it too late to plant tree saplings in Zone 7?

The answer depends on the tree species

While spring and fall are optimal times for planting, the answer depends on the tree species. Some species are hardy enough to tolerate planting in the summer, while others prefer to be planted in the cooler months to avoid heat stress.

Evergreens such as cypress, pine, and spruce are susceptible to moisture stress during their establishment period, which can extend up to two years. Planting saplings in the summer when soil moisture is low can cause damage to the roots, leading to a failed planting. For these evergreens, it's best to plant in spring or fall.

Deciduous trees such as maple, oak, and ash have a better chance of survival when planted in the fall when soil and air temperatures have started to decrease. The cooler temperatures allow the roots to establish before winter dormancy.

You can increase your saplings' chances of survival

Regardless of the tree species, planting saplings in the summer can be challenging. However, there are steps you can take to increase your saplings' chances of survival

One essential step is to ensure that the planting site has adequate soil moisture. Water the sapling thoroughly before planting and provide enough water throughout the first year, especially during hot and dry spells. Apply a 2-3 inch layer of mulch around the sapling to help conserve soil moisture and regulate soil temperature.

Another crucial step is to protect the sapling from excessive heat and sun exposure. You can use shade cloth or create a shade using temporary structures such as burlap or old sheets. Ensure that the shade cloth or burlap is positioned in a way that allows air circulation and does not touch the sapling.

Conclusion

In conclusion, it's not too late to plant tree saplings in Zone 7 as long as you choose a species that can tolerate summer planting and take the necessary steps to ensure their survival. However, for evergreens and other species that prefer cooler temperatures, it's best to wait until the fall when soil and air temperatures have started to decrease.

Remember that planting saplings requires planning, preparation, and maintenance to ensure their survival and long-term health. With the right approach, you can enjoy watching your saplings grow into magnificent trees that provide shade, beauty, and environmental benefits for years to come.
