Growing fruits and vegetables
Vegetable Seasonality Chart
The Old Farmer's Almanac gardening calendar stretches from spring through fall planting. It not only tells you when to sow indoors and plant in the ground, but also when to harvest- and is customized to your location based on the nearest weather station.
Interactive Garden Planner
The Garden Planner makes it easy to draw out your vegetable beds, add plants and move them around to get the perfect layout. This program has over 180 vegetables, herbs and fruit, with location-specific detailed growing information. Crop rotation is easy as the Garden Planner warns you where you should avoid placing each vegetable based on what was in your previous years' plans. This program has a 7 day free trial with full access ($29/year after that), with no payment info required for the trial period.
Garden Pests and Diseases
This extensive list provides information on how to identify, control and get rid of pests and diseases that may negatively impact your garden.
For each plant, The Old Farmer's Almanac has identified the hardiness zone, sun exposure, soil type, soil pH, pests and problems, harvest tips, recommended varieties and special features.
