Researchers from the University of Bath will be constructing a “BaleHaus” this summer made from prefabricated straw bale and hemp cladding panels.

The house will be a model for building carbon zero homes of the future. And because straw and hemp efficiently absorb carbon dioxide while they grow, the buildings made from them might even have a negative carbon footprint.

Bare, exposed soil rarely exists in nature, so why should it be in your garden? Mulching with an organic mulch like straw will build healthy soil, conserve water, and help keep weeds at bay. In other words, it creates less work for you! Mulch is truly a gardener’s best friend!

It seems like all I’ve been doing lately is weeding and mulching. It’s taken longer than I wanted, but slowly but surely my garden beds are enjoying a nice layer of straw to help insulate the soil, form a layer that’s harder for weeds to penetrate, and retain moisture. I usually wait until plants are established before mulching, but I’ve recently learned about year-round mulching, which doesn’t sound like such a bad idea.

What is mulch? It’s basically any material (usually organic matter) that is used to cover exposed soil in the garden, and can be used for beds, containers, and even paths. Exposed soil can dry out quickly and be easily eroded by water and wind, so a covering helps keep it moist and healthy. The type of mulch you choose depends on the needs of the area you’ll be mulching, but I recommend staying away from unnatural materials like black plastic and choosing organic materials like straw, hay, decomposing leaves, rice hulls, or even dead & dried out weeds. Organic material will break down slowly and help add humus to the soil, making it richer and healthier for gardening.
