For better tomatoes, go deep

Plant seedlings deeply; water deeply, too

Happy Tomato Planting Day!

Yes, we have radio host Farmer Fred Hoffman to thank for this unofficial Sacramento holiday. His birthday is April 28 and coincidentally that day meshes nicely with the perfect planting date in our climate for our favorite crop.

With the current high heat, you may want to wait a few days if you don’t already have your transplants in the ground. Temperatures are supposed to cool way down this weekend with highs in the low 70s – still warm enough for tomatoes, but a lot more comfortable for gardeners.

Fred offers tons of valuable tips on growing great tomatoes on his website, www.farmerfred.com . Among his most useful for planting day: Plant deeply.

Unlike most other plants, tomatoes are not transplanted with the same soil level as they grew in the pot.

Says Fred, “Place the tomato deep into the soil, clipping off the lower leaves and leaving only the top leaves and branches exposed. This will cause more roots to develop along the stem, speeding development.”

It also allows the tomato plant to develop a bigger root system, capable of pulling up more nutrients from the soil and more water.

Speaking of water, Pete Frichette – Sacramento’s Tomato King – trains his transplants to go deep. He does this by thoroughly soaking the planting area in advance.

Here’s his explanation:

First, he dug out a “pan” about 3 inches deep running the length of the planting bed. In addition, he dug big holes, each another 18 inches deep.

“This area has been filled about five times and the water then allowed to soak into the surrounding soil,” Pete explained. “Next, I will fill just the holes with my planting mix, one-third existing soil, one-third commercial potting mix and one-third my own compost mix. This I will then soak, then plant my tomato, which I will also water well in. Then, I will bring the top soil back into the pan and wet it in, also. That will be the last water the transplants will see for eight to 12 days, depending on the weather.”

If it gets too hot, he’ll give the new transplants a drink. “The leaves will generate the required signal,” he said, referring to drooping foliage. “Meanwhile, the concept is that the roots will follow the moisture downwards, thereby forming a deeper root ball and a healthier overall plant.”

Another trick that Pete uses for bigger, more bountiful plants: He places a 5-gallon bottomless bucket around each seedling. When he feeds his plants, he uses diluted liquid fertilizer, poured inside the bucket. It’s also handy for deep watering.

Garden checklist for week of Aug. 2

Get out early in the morning and monitor your garden’s moisture needs. Deep water and add temporary shade structures for plants that are feeling a little burned. In particular, protect developing peppers and eggplant.

* Put off fertilization until this heat passes; plants need to concentrate on hydration instead of growth.

* Harvest tomatoes, beans, squash, pepper and eggplants to prompt plants to keep producing. Give your plants a deep watering twice a week, more if planted in containers.

* Watch out for caterpillars and hornworms in the vegetable garden. They can strip a plant bare in one day. Pick them off plants by hand in early morning or late afternoon.

* Mulch can be your garden’s best friend – it conserves moisture while blocking out weeds. But don’t let mulch mound around stalks, stems or trunks. That can promote rot.

* Pinch off dead flowers from perennials and annuals to lengthen their summer bloom.

* Pick up after your fruit trees. Clean up debris and dropped fruit; this cuts down on insects and prevents the spread of brown rot.

* Prepare for a fall full of flowers by paying a little extra attention to your garden. Cut off spent blooms from roses, annuals and perennials. Roses will rebloom about six to eight weeks after deadheading.

* Indoors, start seedlings for fall vegetable planting, including bunching onion, cabbage, broccoli, cauliflower, kale, radicchio and lettuce.

* Sow seeds of perennials in pots for fall planting including yarrow, coneflower and salvia.

* In the garden, direct seed beets, carrots, leaf lettuce and turnips. Make sure to keep seeds and seedlings consistently moist.

* Plant potatoes.
