The Bright Side of Cloudy Skies
 
Greetings!

veronica with garden vegetablesIf you're lucky enough to have decent drainage in your garden, all this rain hasn't been too bad. Sure, I got 3 inches one day and a full inch the next on already saturated ground, but those raised beds I built and all that compost I've been working into the soil are doing their job. The soil is loose and water drains away beautifully. Meanwhile, the only watering I've done is of the odd container here and there. And the soil is wonderful for pulling weeds, allowing me to easily get roots and all.
   Even fungal problems haven't been too bad, probably because between most soakers, we get a day or half day of warm, breezy weather that dries the foliage. Even my tomatoes, the most disease-prone plants in my garden, are looking good.
   The vegetable garden overall is kicking into gear and I'm trying to get out there daily to collect all that wonderful produce (cucumbers anyone?)
        
Happy gardening between the raindrops!

Slugging It Out With Slugs

With all this wet weather, the slugs are lovin' it and are very active. My hostas are excellent evidence of this, I'm sad to say.

Arrangement of the Week

hosta leaves as a flower arrangementWith all the flowers exploding with color outside my window, I don't crave having lots of colorful flowers indoors--the way I did in say, February. This time of year, I want something cool, refined, and soothing. A few ferns in the vase are perfect but I also love cutting a few hosta leaves and tucking them into wet floral foam in a vase. Simple, elegant.
Blossom End Rot

Another side effect of all this rain: Our tomatoes have developed rotten black spots on their ends, called--appropriately enough--blossom end rot. There's not much you can do,tomato with blossom end rot - bleah! other than to remove the diseased tomatoes in order to allow the plant to spend more of its energy into fruit production.
   Click here for info from ISU on the causes of blossom end rot and what you can do, in other years, to prevent it from reoccurring.
Blow Mosquitoes Away

mosquitoKeep mosquitoes and other bothersome flying insects at bay while enjoying your porch or deck with an electric fan or two. Mosquitoes, especially, are too fragile to fly in a breeze. Just be sure to plug the fans into a shock-proof GFCI outlet. You'll stay cool and the bugs will say away.

Garden To-Do List

 Get out there and check your veggies daily. A cucumber that's a little small one day can get huge in just a day or two. Pick veggies small and often for top quality and flavor and to encourage more production. Click here for our best harvesting tips.

Weed! All this rain followed by warmer weather is perfect conditions for weeds to take off.  After weeding, mulch to prevent weeds from returning.

 Keep up with the mowing. All this rain makes grass grow fast, but as a rule of thumb, you shouldn't remove more than one-third of the leaf blade at a time or you stress the grass. And stressed grass gets diseases and weeds. Mow often for a healthier lawn.

Deadhead flowers on annuals, perennials, and some shrubs. It keeps your garden more attractive and in many cases, it will encourage more flowers longer.

Fertilize containers every two or three weeks with a liquid fertilizer, such as Miracle-Gro. All that watering flushes out nutrients. Use a "bloom booster" type for flowering plants--it really makes a difference!

Continue to plant container-grown or balled-and-burlapped trees, shrubs, and roses now. However, avoid planting bare-root roses and other bare-root lants. This late in the season, they'll struggle to get established.

 Time to practice tough love. If a tree or shrub is still struggling with winter damage or overall sickness, with significant amounts of dead wood, it's almost certainly time to dig it up or cut it down.

Remove old raspberry canes after the plants stop producing fruit.

 Check out the bulb catalogs and on-line sources. Ordering now assures the type and quantity you want this fall, when supplies run low.
