Spring Gardening Checklist

Checkbox-imagePLANT COLOR

An ideal time to plant colorful, summer-blooming shrubs like spirea, hydrangea and easy-care shrub roses. We also swear by Fertilome Root Stimulator and Elements, on organic Fertilizer.


With a pot trellis, containers turn colorful vining plants like mandevilla, moonflower, black-eyed susan vine or morning glories into vertical art.


Schedule a Snapshot Gardening Consultation at the garden center to get you going in the right direction. Find out more. Perfect for DIYers and created for small spaces.


Pinch off dying/dead flowers to make room for new ones and help things along with Jack’s Petunia Feed.

Checkbox-imagePRUNE LIKE A PRO

The perfect time to prune early spring flowering trees and shrubs like lilacs (once their flowers have faded or fallen). Find the imaginary center of the shrub or tree, then visualize the general shape that builds around it. You don’t have to be perfect, just trim any wayward branches right above one or more healthy leaf buds.

Let’s grow together. Stop in, call 317.733.GROW and find what you need online.

Private Events at Altums

You Need Your (Meeting) Space

The garden club (or any club for that matter) has officially outgrown your living room. And it’s just not practical hosting book club, mom’s night out or your fundraising committee on the deck in December. We’ve got plenty of space for private groups to:

Spread out. Our Education Center is roomy yet cozy (30 people comfortably).

Make it yours. Set up tables and chairs in stations, groups, however you like. You can even arrange to have it greenscaped.

Cater to your guests. Bring your own goodies.

Mix it up. Invite a friendly Altum’s landscape designer to speak to your group or lead you in a make & take home garden demonstration (e.g. container gardening, terrariums, fairy gardens, wreaths and more).

Email Karen at for details and dates.
