Healthy soil means thriving plants. Yet untangling the soil food web and optimizing your soil health is beyond most gardeners, many of whom lack in-depth knowledge of the soil ecosystem.

Soil Science for Gardeners is an accessible, science-based guide to understanding soil fertility and, in particular, the rhizosphere – the thin layer of liquid and soil surrounding plant roots, so vital to plant health.

Robert Pavlis, a gardener for over four decades, debunks common soil myths, explores the rhizosphere, and provides a personalized soil fertility improvement program in this three-part popular science guidebook. Coverage includes:

• Soil biology and chemistry and how plants and soil interact
• Common soil health problems, including analyzing soil's fertility and plant nutrients
• The creation of a personalized plan for improving your soil fertility, including setting priorities and goals in a cost-effective, realistic time frame.
• Creating the optimal conditions for nature to do the heavy lifting of building soil fertility

Written for the home gardener, market gardener, and micro-farmer, Soil Science for Gardeners is packed with information to help you grow thriving plants.

With easy-to-follow, step-by-step instructions, veteran horticulture teacher Miranda Smith provides a complete reference showing every step for cultivating new plants—whether from seed or cuttings or with techniques such as layering, grafting, and budding.

Propagating new plants from existing ones is not only sustainable but also rewarding for gardeners of all skill levels. The Plant Propagator's Bible offers a solid and complete, go-to reference for expert gardeners but is also a perfect primer for novice plant lover and horticulturalists.

Smith teaches readers, with the support of hundreds of 4-color photos and detailed illustrations, the natural process, and conditions in which plants grow and reproduce, and shows gardeners how to use these systems to propagate any plant that grows in their garden or greenhouse—or even on their windowsill. The book features:

• An A to Z directory of more than 1,000 individual plant species—with appropriate propagation techniques for aquatics, ornamental plants, houseplants, shrubs, trees, vegetables, and wildflowers
• "What Can Go Wrong" advice for each type of plant, explaining potential problems and how to prevent or fix them
• Detailed, step-by-step illustrations and annotated photographs

Including information on essential tools and equipment, this is an indispensable addition to every gardener's bookshelf.

Increasingly unpredictable weather patterns and pest infestations are challenging today’s vegetable gardeners. But best-selling author Niki Jabbour has a solution: Growing Under Cover. In this in-depth guide, Jabbour shows how to use small solutions like cloches, row covers, shade cloth, cold frames, and hoophouses, as well as larger protective structures like greenhouses and polytunnels, to create controlled growing spaces for vegetables to thrive.

Photographed in her own super-productive garden, Jabbour highlights the many benefits of using protective covers to plant earlier, eliminate pests, and harvest a healthier, heartier bounty year-round. With enthusiasm, inventive techniques, and proven, firsthand knowledge, this book provides invaluable advice from a popular and widely respected gardening authority.

Similar to a cold frame or greenhouse, the polytunnel "Superdome" provides optimal protection from frost and extreme heat for your delicate young seedlings (which also ensures safer and more productive cultivation). Shading material sewn into the polytunnel roof protects young seedlings against the midday sun and heat, while two side openings allow for ventilation, more accessible plant care, and watering. In the growing season, the ideal conditions inside the Superdome provide a head start of at least two weeks.

Comes complete with tensile ropes and ground hooks.

Mt. Hood Series Features

The Mt. Hood greenhouse models are six feet wide with plenty of headroom at 8’4" tall at the peak. Narrow enough to fit in a limited space, each kit is made with a clear natural redwood frame and twin wall polycarbonate and includes two vents with automatic vent openers, Dutch doors, and a base made with recycled plastic.

With the pre-assembled panels, you can easily assemble your GardenHouse in just a short time. Each kit includes easy-to-follow printed instructions, clearly labeled panels, as well as an assembly video.

Automatic Vents Simplify Climate Control

Automatic vent operators on the roof and base vents require no electricity or batteries. The vent operator contains a paraffin (wax) that expands when the temperature reaches about 65°F, pushing the vent open to its fully opened position at about 85°F. As it cools and the paraffin contracts, the operator’s springs draw each vent closed. It is adjustable within approximately 5°F and easily detachable for manual operation.

The door measures 28" wide x 78" tall.

The shipment will arrive in five boxes, weighing around 438 lbs. Two people are recommended to move the boxes. Each box will be large and weigh up to 90 lbs. Please allow six to eight weeks for delivery. Only available for shipment to continental U.S.A addresses.
