Precision Drip Spikes

.

Last May 30 I posted that I was going to try Precision Drip Spikes to help keep my potted pole beans and bush cucumbers watered during the summer.

I ordered a pack of four spikes for $16.95 from Gardener’s Supply. Each “Spike” consisted of a 7" spike to fit in the water bottle, a tiny hose and a small “dripper” spike. The water bottle is not included.

A numbered dial on the "dripper" spike sets the amount of water to be released.

According to the instructions, “When you plant the (dripper) spike the water outlet must not come in contact with the soil.”

The first thing that happened with the Precision Drip Spikes: The 2 liter bottle spike sunk in the soil and it was difficult to put the drip end in the soil without getting it too deep. I tried to prop the bottle on some flat stones and lean it against the pot. There was still an S-shaped curve in the hose. A smaller bottle didn’t work much better.

I fiddled around with it for weeks. If I got everything right, it worked well. Some times it created a vacuum and no water came out at all. I finally took them out. I think it takes someone with more patience than I have to get the Precision Drip Spikes working correctly.

I’ve read that some people cut the bottom off the water bottle which makes it easier to refill and eliminates the vacuum problem. I may try that next year.

Return on Investment (ROI)

.

Years ago, when I was naive enough to think I could understand business planning and investments, I read a lot about Return on Investment (ROI).

This morning I picked beans from the potted pole bean plants. This is about the 5th or 6th picking. Not bad for the price of 4 bean seeds. (Of course I've not factored in costs of soil, water, fish emulsion fertilizer or labor.)

To me this is a great ROI - especially since the labor is free.

Watering Container Plants

.
Drip-it Pro Waterer (see May 11, 2008 post) was designed for house plants. I tried it with my vegetable container plants this summer. I have one in a pot of pole beans and one in a pot of cucumbers.

I filled the water containers about once a week. The 8” water bottle holds about 4 cups of water. It is simple to fill and use. The T-shaped “wick” sometimes fell out as I put the pronged cap on. But, they were easy to put back in place.

I still had to water once or twice a day in the summer heat. The water bottle may have helped keep the pots from completely drying out.

I think they will work for my large house plants while I’m on a 2-week vacation this winter.

Garden Homecoming

.

I was on vacation last week – a very relaxing time away from home. The garden is looking only a little neglected. Fortunately, my friend Cindie watered the pots for me. Without her, they would have been toast!

The hydrangea (Hydrangea ‘Venice’) is blooming. The color this year goes from pink through lilac to purple. I never know what color it will be. Last year it was a bright pink. (see July 25, 2007 post) It is full of blooms. I mean FULL of blooms. The leaves are barely visible.

The Lace Cap is also blooming profusely. They are both happy in their spot – shaded from the hot afternoon sun.

The potted zinnias (Burpee Giant Flowering Mix and Magic Carpet Mix) look good on the patio. It’s too early for mildew.

The ('BrandyBoy') tomatoes are getting round and plump. I picked beans. The cucumbers are growing from their pot. I made cucumber salad. The 2 "Drip-Pro Waterer"s that I bought from Gardener's Supply seem to keep the potted vegetables from completely drying out.

Not everything looks as good. Japanese beetles are feasting on canna leaves, roses and pole beans. Dead looking, lace-leaved cannas are not a pretty sight. I haven’t found a way to get rid of those armored chewers. I never seem to have time to knock them in a bucket of soapy water. Karen Bernhard, Entomologist, Lehigh Co. Cooperative Extension, published Japanese Beetle information in “Penn State Master Gardeners” blog in the Morning Call July 10. http://blogs.mcall.com/master_gardeners/

Weeds that were tiny when I left are now large enough to have seed heads. Crabgrass, ever the opportunist, has sprouted in every unplanted inch of ground. I pulled one clump as big as a head of cabbage. The lilies are finished blooming and seed heads need to be cut off. Same with the hostas. The sweet alyssum needs a trim. Garden paths are overgrown. There’s compost tea to make. Annuals need to be fertilized.

Lots of work to do to catch up but it’s good to be back in the garden.

2007 Garden

As I looked through the garden photos from 2007, I found some winners and some losers and a few that were a little of both.

Losers

The pot of Double Flowering Tuberose (Polianthea tuberosa) did not bloom (again). I promised myself if there were no blooms in 2007, they would be compost. But, I've the pot away for the winter (again). (see December 29, 2006 post). We’ll see. I get plenty of green leaves and lots of new bulbs each year, but no blooms. I don't know if I'm ready to give up the challenge.

Lobelia 'Crystal Palace' started with a few pretty, bright blue flowers in a pot with zinnias. They never developed into much. I’m not sure if it was the competition from the zinnias or the shade from the zinnias or the hot, dry summer. I've tried nasturtiums and petunias in the bottom of this patio pot. Neither one worked very well. I’ll be looking for a different cascading plant this spring. I may try some of the bright sweet potato vines.

In the middle

Container Vegetables. The cucumber (Bush Champion) plants produced a normal amount of cukes before they were overcome with mildew. I may try a mildew resistant variety this year. The beans (Kentucky Wonder) were a success producing beans into fall. But, keeping the containers watered was a problem in the hot, dry summer. I will be researching watering methods and gadgets this winter.

Making aerobic compost tea was easy enough to do. (see July 7, 2007 and August 8, 2007 posts) I think I got some good results on the roses. I’m not sure how valuable it is as a soil amendment. I’ll be trying it on a portion of the lawn next spring. At the very least, I got to stretch my valuable compost a little further.

Sweet Pea (Sweet Dreams & Streamers Mix) took a long time to germinate. Half of them turned brown and withered. The other half produced a fair amount of flowers. The flowers were almost exclusively lilac colored with few exceptions. There was no noticeable fragrance.

I’ll get to the winners next time.
