As you start to plant things for fall*, here are some things to keep in mind... Your soil is likely fairly tired after the spring season. We had lots of rain and early heat. Give your soil a refresh with some good compost after you pull out your spring crops and before you plant your fall stuff. I usually mix about one bag (2 cu. ft.) into the top 6-8 inches of soil for every 9 square feet of garden space for a mid-crop boost. This morning, after hand watering the front display garden and...

In addition to taking Saturday's fall vegetable garden class, here are three ways to prepare: Pull out all spent spring vegetables (tomatoes, cucumbers, squash, beans) and amend the area with high-quality compost.These vegetables are done producing for the season because high summer heat inhibits pollination. To prevent future...

Good morning! I hope that you are finding creative ways to stay cool this week. The first week of triple-digit heat always makes me feel icky and off. I'm staying busy indoors with baking bread for tomato sandwiches and finding creative uses for the figs that are now starting to ripen on my tree. Here are 5 suggestions for what you can do this weekend in the garden: Begin sowing sunflowers and zinnias in succession.

This sunshine is nice, right? Such welcome relief from the constant deluge. This morning I dedicated a good chunk of time to fertilizing everything. Things actually look pretty good, all things considered. I added a fresh layer of mulch just before the rains came, and that really kept things happy and healthy. The delphiniums and snapdragons are still blooming well, but the foxgloves and poppies are toast and have been pulled to make room for the 'Indian Summer' rudbeckia, 'Mystic Spires'...
