Please remove them from your yard and place in the garbage.

Tips for rebate success with drought tolerant plants Please refer to the Principles for Garden Success on the next pages to ensure your gardening efforts are successful and your plants thrive.

• Please note: pay close attention to the latin plant name to ensure it matches . Take a high quality photo of each plant in its pot with the plant identifier tag beside or in front of the plant. Photos of groups of 3 plants are permissible, if all tags are legible • After planting, mulch the area with 2 inches of mulch in order to prevent water from evaporating. (Note: mulching is a requirement for this rebate.) • Trees need to have 3-4 inches of mulch around the base of the trunk and surrounding root circumference. Be careful not to cover the base of the trunk on trees and shrubs to avoid decay and rodent problems. • Take a photo of the plants in their new garden space. If a medium to large space was established, please take several photos of sections of the garden. • Highlight and label the eligible plant items on your receipt; this is especially important if you bought other plants that are not eligible for the rebate at the same time. • Please note: plants put in pots and planters are not included in the rebate program. 2021 Rebate Program Principles for Garden Success Protect your garden investment by making sure that your new plants will survive and thrive in your yard. A few simple steps will ensure that your plants come back year after year.

Get to know your yard Before1 you purchase any plants, make notes regarding the conditions around your yard: • Which areas of the yard are sunny or in shade? • Which areas offer shelter from the wind? • What are the soil conditions when the ground is dry? • Typically, soil in Okotoks contains a lot of clay or sand. You may need to amend your soil if it is too sandy, or is hard and full of clay. Sandy soil allows water to drain too easily, while clay soil is slow to drain water. Both of these soil types make it difficult for plants to thrive. • Try the press-test: take a quarter-sized amount of soil in your palm and press it down with your thumb: • If the soil stays extremely loose and does not hold a shape, it contains a high percentage of sand. • If the soil keeps the shape of your thumb and does not easily crumble when moved, it contains a high percentage of clay. • If the soil keeps the shape of your thumb initially but crumbles when you move it, it is a good loam soil. • Adding some compost is a great way to add movement and nutrients to difficult soil. Employees at a local garden centre can answer your questions about soil, sun and shelter requirements.

Harvest free rainwater •2 Save money on your utility bill - use a rain barrel or two to capture rain water. Your plants and wallet will thank you! • Don’t forget that rain barrels are part of the rebate program too. Or… • Filled up the kiddy pool? Use that water for your plants!

Match plants with yard conditions Select3 plants from the rebate drought tolerant plant list that would grow well in the conditions your yard offers. 2021 Rebate Program

Map your yard •4 Using graph paper to sketch your yard space, sun and soil conditions, slopes and water drainage, and where plants can go is a great way to map out and plan your garden • Decide where plants should go based on their sun and soil demands, and grow plants with similar growing needs together. • Before planting trees or large shrubs, make sure you know where your utility lines are. Visit albertaonecall.com

Mulch 5• After you have finished planting, add a 2-inch layer of mulch in the garden while leaving an inch around the plant stock. • Mulch is a layer of organic materials (shredded bark or wood) that will help the soil to retain moisture and help to keep out weeds.

Plant after-care •6 Your new drought tolerant garden will require more water (2-3 times a week, depending on heat and rain) during the first year that it is being established in your yard. This may seem counterintuative; however watering well during the first season will make sure the root system is healthy enough to survive with reduced water. • Next year, once the plants are established and mulched well, the watering needs will diminish substantially. • Use a natural fertilizer every two weeks when watering the establishing plants. • Ask your local greenhouse about eco-friendly fertilizers or make your own.
