I’ve devoted several columns to the care of hydrangeas. Recently, I’ve seen many people asking about how to care for hydrangeas received as gifts. These florist hydrangeas are a popular Mother’s Day gift, prized for their large, colorful blooms and lush foliage. They (Hydrangea macrophylla) are typically grown in greenhouses and forced into bloom early, which means they require some special care to maintain their beauty indoors and, potentially, outdoors in the landscape.
When first received, place the plant in a bright, indirect light location indoors. Avoid direct sunlight through a window, which can scorch leaves and shorten the lifespan of blooms. Ideal temperatures are cool to moderate—around 65–72°F during the day and slightly cooler at night.
Consistent watering is critical. Hydrangeas are sensitive to drought stress and will quickly wilt if the soil dries out. Check moisture daily by touching the potting soil; water thoroughly when the surface begins to feel dry. Ensure excess water can drain freely—decorative foil wraps or containers can trap water and lead to root rot if not removed or periodically drained.
To extend flowering, keep the plant away from heat sources such as vents or appliances. Remove spent blooms as they fade to improve appearance and reduce stress on the plant. While fertilizer is not necessary during the flowering period, a light application of a balanced liquid fertilizer every 2–3 weeks can help support foliage if blooms begin to decline.
In South Louisiana, florist hydrangeas can be moved outdoors once the risk of cold weather passes. Gradually acclimate the plant by introducing it to outdoor conditions over several days, starting with a shaded, protected spot. I see many people try to immediately plant them outdoors before they have acclimated to their new environment.
Hydrangeas prefer well-drained soil rich in organic matter. Make sure to prepare the planting bed ahead of time by amending native soil with organic matter such as compost or composted manure. Avoid planting in full afternoon sun, which can cause leaf burn and stress. They perform best in partial shade, especially morning sun with afternoon shade.
If you wish to keep your hydrangea long-term, transplant it into the garden or a larger container. Dig a hole slightly wider than the root ball and plant at the same depth as it was in the pot. Water thoroughly after planting and apply a 2–3 inch layer of mulch to conserve moisture and regulate soil temperature.
Keep in mind that not all florist hydrangeas are perfectly adapted to landscape conditions in Louisiana. Some may rebloom inconsistently or struggle in high heat. However, many gardeners have success when plants are placed in the right conditions and given proper care.
Most bigleaf hydrangeas bloom on old wood, meaning next year’s flowers develop on stems produced this season. Avoid heavy pruning after mid-summer, as this can remove next year’s flower buds. Instead, limit pruning to removing dead or weak stems and shaping immediately after flowering.
Maintain even soil moisture throughout the growing season and fertilize in early spring and again in early summer using a balanced landscape fertilizer. Monitor for common issues such as leaf spots or insect pests, although serious problems are relatively uncommon with proper care.
It’s important to note that greenhouse-grown hydrangeas may not rebloom as predictably as nursery-grown landscape varieties. Flower color may also shift depending on soil conditions—especially soil pH, which influences blue or pink coloration.
With attentive care, many Mother’s Day hydrangeas can transition from short-term gifts into long-lasting additions to the home or garden. Even if blooms don’t return immediately, healthy foliage and occasional flowering can still provide enjoyment for seasons to come.
