Garden After the Heatwave and a Greenhouse Full of Sensors: This Week in Brief

Summer has taken its toll not only on home garden owners, but also on professional plant growers. In this roundup, we look at how to safely bring plant life back after a heatwave, and how Dutch technology is helping greenhouse growers better control the root zone.

Garden after the heat: don't rush for the axe or the fertilizer [1]

If, after this year's heatwave, your lawn and flower beds look like a battlefield, not all is lost. As experts point out, many plants that appear dead have actually survived the extreme temperatures — simply scrape the bark of a stem gently to check whether the tissue underneath is still green [1]. It's a simple test worth doing before reaching for the pruning shears.

The article's authors warn against two instincts that can make things worse: fertilizing hard, parched soil, and drastically cutting back weakened plants "just in case" [1]. Instead, patience is recommended — the plants themselves will show which parts can still be saved. September, on the other hand, is a good time to overseed the lawn, giving it a chance to recover before winter sets in [1].

There's also an interesting long-term angle: as heatwaves become more frequent, gardeners will increasingly turn to Mediterranean plants, naturally adapted to drought and high temperatures [1]. It's a sign that designing climate-resilient gardens is no longer a niche trend, but is becoming the standard.

While hobby gardeners are learning patience and observation, professional greenhouse plant growers are heading in a completely different direction — betting on data and automation.

The Dutch company Ridder has announced the integration of Quantified's wireless sensors with its Hortimax Plus and Hortimax Pro climate computers [2]. These sensors measure several parameters at once: substrate moisture, drainage, weight, and the plant's own temperature.

Thanks to this integration, greenhouse growers gain a much fuller picture of what's happening in the root zone — all linked with climate and fertigation data on a single, unified platform [2]. Instead of juggling several separate systems, growers can make decisions based on one complete set of information.

A Ridder representative highlighted something that sounds like a motto for the entire precision growing industry: growers want the freedom to choose the technologies that best fit their own operation [2]. That's an important signal for suppliers of irrigation systems and smart garden solutions — open, integrable platforms are gaining the upper hand over closed ecosystems.

Summary

Summary

This week shows two sides of the same coin: on one hand, patience and careful observation of nature after extreme weather conditions; on the other, increasingly precise tools that let professionals get ahead of those same challenges. Both approaches share one thing in common: the need to better understand what's happening beneath the surface of the soil.
