August Garden Guide

In Houston, during the months of August to October, you can witness the migration of several species of hummingbirds as they make their way from their breeding grounds in North America to their wintering habitats in Central America and Mexico. The most commonly observed species in this region include the Ruby-throated Hummingbird and the Black-chinned Hummingbird.

Preparation and Feeding: In preparation for migration, hummingbirds will intensively feed to build up their fat reserves. They need these reserves to sustain themselves during the long journey. This is a great time to set up hummingbird feeders in your yard with a mixture of sugar water (4 parts water to 1 part sugar) to help them refuel.

Remember that while observing hummingbird migration can be exciting, it’s important to avoid using red dye in sugar water mixtures (as it could be harmful) and to keep feeders clean to prevent the growth of mold and bacteria. Providing a safe and nourishing environment during their migration journey can play a role in supporting these incredible birds.

Watering & Mulch

Water your plants deeply early in the morning to reduce evaporation and give them time to absorb moisture before the heat of the day

Water lawns deeply and less frequently to encourage deep root growth.

Apply a layer of organic mulch around your plants to help retain soil moisture, regulate soil temperature, and suppress weed growth.

Water container plants more frequently because of the heat


Trim back any dead or diseased branches from trees, shrubs, and perennials.

Cut dead & spent crape myrtle blooms at the end of the month to promote new blooms in the fall

Raise the mower height to reduce stress on the grass during hot periods


Avoid heavy fertilizing, use slow release fertilizers like Nelson’s!

DO fertilize bougainvillea, roses, crape myrtle, palms & hibiscus

Water in your plants with liquid seaweed or SUPERthrive to help with stress from heat
