Old-time gardeners understood something modern rose lovers have forgotten: a simple row of chives or garlic can replace the spray bottle entirely. Science now confirms what the potager tradition knew instinctively—companion planting with alliums reduces aphids by 80% and prevents black spot fungus through pure chemistry.
That vigorous shoot at the base of your rosebush isn’t a bonus—it’s a takeover attempt by the rootstock. Most garden roses are grafted plants, and their wild rootstocks constantly send up aggressive shoots that steal nutrients from your prized blooms. Here’s how to identify them and remove them properly.
Experienced gardeners have discovered a simple companion planting secret: catnip (Nepeta) naturally repels aphids while attracting the beneficial insects that keep pest populations in check. By understanding the chemistry and placement strategy behind this approach, you can eliminate the need for chemical sprays and create a self-regulating garden ecosystem.
