One bottle,
weeks of fresh nectar.
Donaldson Farms is a small family business that has been making plant-based garden and wildlife solutions since 2016. Nectar Extender keeps a feeder fresh so hummingbirds keep coming back.
Hummingbird Nectar Extender, 16oz
Mix it into your nectar and it stays fresh for up to two weeks, so refills and scrubbing happen less often.
What is in it,
and what it does.
Plant-based ingredients that naturally keep mustiness away from nectar for up to two weeks, gentle on hummingbirds.
What a feeder cycle
usually looks like.
Written from the product's own instructions. One mix stretches your refill schedule considerably.
You mix it into your nectar
1 tablespoon of extender per quart of nectar, shaken together before filling the feeder.
Nectar resists mustiness
Instead of turning cloudy in a few days, the nectar holds up.
You are not back at the sink yet
Up to two weeks of freshness means far fewer scrub-and-refill cycles.
You mix another batch
One 16 oz bottle covers many batches through a full hummingbird season.
Next to plain
sugar water.
Plain nectar turns musty in days. A small amount of extender buys you weeks.
Donaldson Nectar Extender
Freshness window is up to 2 weeks per the product's own instructions; actual time varies with heat and sun exposure.
The people who
reach for this.
A few situations show up again and again with hummingbird feeders.
Tired of daily scrubbing
You are refilling and scrubbing the feeder every few days and want that chore to shrink.
Feeds an army
You go through a lot of nectar and want a bigger bottle that stretches further, as one reviewer put it.
Hot climate feeder
Heat speeds up spoilage, and you want something that fights back.
Wants more visitors
You want the feeder fresh and inviting enough to keep hummingbirds coming back.
I fell in love with a nectar extender from my local bird store (small bottle) since I make enough nectar to feed an army, especially during the summer. I wanted a bigger bottle. I found Donaldson Farms and haven't looked back. I love supporting small businesses whenever I can for quality products.
