7 Tips for Successful Planting During a Dry Fall
Fall planting is usually ideal. Even in an unusually dry season, fall remains a good time to plant. However, your approach needs to be adjusted to give young trees the best chance to establish properly. Here are our 7 essential tips to help you succeed—even during a dry fall.
1. Choose the Right Timing
-
If possible, wait for a significant rainfall before planting. The soil should be moist at depth to support root establishment.
-
If dry conditions persist, it’s often better to delay planting until conditions improve rather than risk severe water stress. As fall progresses and temperatures drop, plants enter deeper dormancy, reducing their water needs. Planting can typically continue until the end of October—during a dry fall, the second half of the season is often preferable.
2. Prepare the Soil Properly
-
Water the planting hole the day before planting by adding a bucket of water (10–20 L) to rehydrate the soil. In cool fall conditions, moisture will be retained for several days.
-
Loosen the soil thoroughly over a wide area. Normally, the planting hole should be about twice the width of the root ball. In dry conditions, increase this to three times the diameter. Compacted soil limits root growth, and dry conditions tend to worsen compaction.
3. Plant with Care
-
Soak the root ball in a bucket of water until fully saturated before planting.
-
Plant at the correct depth. The root collar should sit level with the surrounding soil surface.
-
Backfill using a mix of native soil (from the planting hole) and compost (up to 20–30%).
-
Firm the soil gently to eliminate air pockets, then create a watering basin around the base of the tree.
4. Targeted Watering
Even in fall, young trees need water to establish strong roots:
-
Water thoroughly at planting to fully saturate the soil around the root zone.
-
Afterward, water regularly—about once every 10 days if there is no rainfall and the soil remains dry. The goal is deep soil moisture, not just surface wetting.
Tip: If possible, a drip irrigation system or a simple DIY watering device (such as an inverted bottle or perforated pipe) helps conserve water while delivering it directly to the roots.
5. Apply a Thick, Effective Mulch
This is key during dry conditions:
- Apply 8–10 cm of mulch (wood chips, leaves, ramial wood chips, surface compost, etc.)
- Extend it over a 1–2 ft diameter around the trunk
- Leave a 5–10 cm gap around the trunk to prevent rot
6. Protection and Maintenance
- Protect young trees from wind using a stake if the site is exposed
- Regularly check that the watering basin and mulch remain effective
- In winter, adding extra mulch helps retain moisture and protect roots from freezing
7. Bonus: Choose the Right Species
- Choose drought-tolerant species. With climate change, extreme conditions are becoming more common, including repeated drought periods. Selecting drought-tolerant species helps improve the long-term resilience of your landscape.
Here is our selection of plants well suited to dry conditions:
Gray Birch: a specialist of poor, dry soils, often a pioneer species on sandy sites.
Black Cherry: well adapted to sandy, dry soils and known for its fast growth.
Red Oak: tolerates dry periods well thanks to its deep root system and relatively fast growth.
White Oak: a long-lived tree that tolerates both drought and poor soils.
Bur Oak: highly tolerant of heat and repeated drought due to its deep roots.
White Spruce: once established, this conifer tolerates dry conditions well and thrives in well-drained soils.
Red Maple: one of our most versatile deciduous trees, adaptable to both dry and moist soils.
Tamarack (Larix laricina): grows in a wide range of conditions and can tolerate drought if the soil is deep enough.
Trembling Aspen: a fast-growing, hardy pioneer species that establishes quickly on poor, dry soils.
Red Pine: highly drought-tolerant and well suited to sandy, well-drained soils.
Red Elderberry: a shrub that adapts well to a range of conditions and supports local wildlife.
Highbush Cranberry: a versatile shrub that tolerates variable conditions and is ideal for natural hedges that support biodiversity.
