A matter of Thyme

It’s planting season. You know it was only a matter of thyme. Herbs are a fun way to get your hands in the dirt and play. Herbs are com-”plant”-able with containers liking warm soil and plenty of sunlight. Containers can be moved inside if needed on frosty April evenings.  Containers will also hold rambling herbs like the various Mints in bounds as opposed to running rampant in your garden beds. Herbs have been used through “thyme” and memorial by the Greeks, Egyptians and ancient Romans as well as the Chinese. Nothing new here. Herbaceous plants have been used for flavorings, scent, food and medicinal purposes for centuries. Herbs and there aroma can trigger some of the strongest and enduring memories for a gardener….we never forget a good whiff. For me it’s Cilantro, a favorite, along with Basil, Lavender and Oregano and Nepeta. How about you? Parsley? Chocolate or Lemon Mint? Regardless it’s “grow” time when you use a good quality container soil and containers that are sizeable enough for root mass but not too large to move into the sun or under cover in the event of a frost event. Some people will tell you not to feed the herbs in your container or they will lose their scent and oils. My position is to feed them, but do it with a slow release fertilizer designed for container growing like Osmecote. You may want to also add a few crystal polymers to the soil to help you with watering even though herbs are more tolerant of some water neglect than other herbaceous plants. The idea is to avoid high nitrogen and quick release fertilizers when growing herbs.

Finally make sure to add a few flowers with your herb container. I like a few edible Pansies or Violas like this one called “Blueberry Thrill.” Another great edible flowering plant to add would be Nasturtiums. If you have some “Thyme” on your hands and a container Herbs may be the answer to get you growing!

 

Free Fertilizer

You can’t beat saving some green while greening your plants. Free fertilizer while you sleep. I’m talking about those wonderful overnight April thunderstorms where the next day everything outside seems greener. It’s not a “fig-leaf” of your imagination. Lightning provides the kick in the “plants” to the spring landscape. Nitrogen plays a critical role in photosynthesis and plant growth. We are surrounded by nitrogen in our atmosphere, but plants must secure their nitrogen in a “fixed” form. This can be done synthetically by the homeowner  picking up a bag of fertilizer at the garden center. It can be done biologically through decay or micro-organisms and bacteria in the soil in association with nitrogen fixing plants or legumes like clover.

It can also be done in an abiotic or atmospheric way via a good lightning storm. Air has nitrogen gas but it is inert and can’t be used by the plants until lightning converts unusable nitrogen into fixed nitrogen. Super charged lightning ionizes the air and the nitrogen oxides are carried by the rain as usable form of greening power. That faint ammonia like odor in the air after lightning is the atmospheric “hotline” answering nature’s call for more greening power in the form of “fixed” nitrogen. Plants can receive and use the greening power of nitrogen as nitrate ions, ammonia or urea. Even though atmospheric nitrogen generated by lightning may produce only 5 to 10 percent of a plant’s nitrogen needs, it is a dramatic way to light up the landscape in green after a spring storm!

“Spring” it on!

This year it feels like we moved from fall right into summer. Record temperatures in March transitioned us from a “non”-winter to summer-like weather. The landscape woke up from it’s winter slumber with a bang similar to someone clanging pots and pans over your head while you’re sleeping.

Magnolia in bloom March 21, 2012

In the matter of just a week soil temperatures rocketed into the 60′s. Last year we didn’t see soil temperatures in the 60′s until well into May.  GDD accumulations (growing degree days) climbed at daily rates of 20 GDD plus getting us to 175 GDD when last year at the same time we were at 7. This past Wednesday we added 22.5 GDD in one day with a high temperature of 83 degrees and low temperature of 62 degrees. The landscape responded by exploding to life 3 to 4 weeks before “normal” dates. Take for example a tree like Bradford Callery Pear. The tree in a “normal” spring would bloom at around 165 GDD or an average date of around April 15-25. This year ornamental pear trees exploded into color on Thursday March 22.

Ornamental Pears blooming by March 22, 2012

In addition to the ornamental pears, other blooming landscape plants burst into bloom at the same time from Magnolias to Redbuds, from Cherries to Flowering Crabs, from Forsythia to PJM Rhododendrons, no gradual blooming this year as they all went “Ka-Bloom” at the same time.

Weather conditions in March 2012 caused the landscape to explode from Daffodils to Forsythia it's all blooming at once!

Crabgrass controls should be applied now with the soaring ground temperatures. Let’s hope we can avoid some hard frosts in the next few weeks as bloom and tender growth has emerged on many plants from 2 to 4 weeks earlier than normal! We have to let nature take it’s course so “spring” it on baby!
