The Dog Days of Summer

Swallowtail butterfly- a regular summertime visitor.

They’re called the Dog Days of summer. You know, those sultry days with the hottest summer temperatures. The name “dog star” comes from the ancient Egyptians who called Sirius, the dog star, after their god, Osiris. His head in pictograms resembles that of a dog. When the Dog Star rises in conjunction with the sun some felt the combination of the brightest luminary of the day – the sun – and and brightest star of the night – Sirius – was responsible for the extreme heat experienced during the middle of the summertime. Since Sirius is the brightest star in the night sky it’s reasonable to guess that it adds some heat to the earth but the amount is insignificant.

The Romans associated the hot weather from 20 days before to 20 days after the conjunction “the dog days of summer” because it coincidentally fell at the time of year when it was very hot. This falls between July 24th and August 24th. The Old Farmer’s Almanac uses slightly different dates but the Dog Days of summer are definitely here.

We now know the heat of summer is a direct result of the earths tilt, but now you know… the rest of the story.

As summer rolls along you may become more aware of the different microclimates in your garden. With the drier and hotter weather this year, some of your plants that used to get along just fine might be showing signs of stress. Taking note of these changes in the performance of your plants is what makes for a more successful landscape. When the weather cools towards the end of September you will want to move or eliminate those plants that aren’t thriving. Be sure to keep a thick layer of mulch on the soil around your plants to conserve that precious water you do allocate to each of your irrigation zones.

One thing I notice when I visit gardens for a consultation is the existing drip system has not been modified for many years, if ever, to allow for the growth of the plants. The emitters which were originally placed at the base of each plant are not even close to covering the current size of the root zone. The crown of the plant is getting overwatered with each cycle but the rest of the plant is bone dry. Time to add more emitters and move them away from the middle of the plant. No sense wasting water that’s not doing the plant much good.

Add the soothing sound of wind chimes to your summer garden.

The dog days of summer may be affecting our gardens but it doesn’t have to stop us from being out in the garden. . The joy of gardening can take many forms including adding a wind chime, bird feeder or bird bath. Groom plants that need some cleanup. Many perennials benefit from a little haircut at this time of year to extend their blooming into the fall season. Santa Barbara daisies fall into this category. Lavenders will keep their compact shape by pruning a third of their branches now. This forces new growth in the center so the plant doesn’t get woody.

Deadhead flowering annuals and perennials as often as you can. Annuals like marigolds, petunias, zinnia and cosmos will stop blooming if you allow them to go to seed. The same is true of repeat blooming perennials like dahlia, scabiosa and lantana. These plants know they’re on this earth to reproduce. If they get a chance to set seed, the show’s over- they’ve raised their family. Try to remove fading flowers regularly and you’ll be amply rewarded.

Swallowtail butterflies are regular visitors to the garden at this time of year. They especially like butterfly bush as well as zinnias and many other flowers. They are easy to photograph if you move slowly.

Growing Great Vegetables- Part 2

I know many people who wait until the beginning of May to start their vegetable gardens for the summer. Conditions may not be right for them to grow cool season vegetables like beets, cabbage, cauliflower, kale, lettuce, unions, radish and spinach. Those plants don?t mind cold soil and chilly weather. But it your?ve been waiting for the perfect time to plant those scrumptious tomatoes you crave- wait no more. And if you plan your garden right you can still grow some of the cool season crops in the shade of your other sun lovers.

Indigo Rose tomatoes

Crops that prefer night temps of 55 degrees and over are tomatoes bell peppers, corn beans, squash, cucumber, muskmelon and pumpkin. Distinctly warm weather, long season crops that need temperatures in the 70’s are watermelon, eggplant and chilies.

Rotate the beds when planting your vegetables to avoid a build up of diseases and insects that can survive in the soil or on plant residue. Don’t plant the same or closely related vegetables where they grew in the last 2-3 years.

Pay attention to the watering needs of each kind of plant, otherwise you might plant high water use vegetables beside ones that need need less water. This can not only waste water but can actually harm plants. A good guidelines is to group plants by how big they get and how fast they grow. The bigger and faster they grow, the more water they’ll use. Plant heavy water users at one end of the garden, light users at the other.

Raised vegetable beds

For instance, plant shallow rooted beets, bush beans, carrots, lettuce, spinach, radishes and other greens together as they grow at about the same rate and use similar amounts of water. Corn, cucumbers, melons, tomatoes and squash combine well as they all grow rapidly and need lots of water. Another tip is not to mix new (successive) plantings of carrots, lettuce and other crops with existing ones as water use changes as the plants mature.

Vegetables at maturity that root over 48 inches deep are tomatoes, watermelon, pumpkin, winter squash, asparagus, sweet potatoes and artichoke. When watering wet your soil to this depth to keep them happy. Moderately deep rooting veggies -36-48 inches- are beet, beans, carrots, chard, cucumber, eggplant, muskmelon, peas, pepper, summer squash and turnip. Shallow rooting -18 – 24 inches – veggies include broccoli, cabbage, celery, corn, garlic, lettuce, onion, parsley, potato, radish and spinach. Water less if your plants aren’t full grown yet.

Vegetables in containers are a great solution if you don’t have much space in the ground to devote to them. Pots warm up quicker in the spring, too. Just about anything that grows in the ground can also grow in a pot or half barrel. This includes vegetables, herbs and even small fruit trees.

Small plants like lettuces, spinach, Swiss chard and herbs grow nicely in smaller pots near the back door while large edibles like tomatoes, peppers, eggplant, squash, cucumbers and melons need more room like a half barrel or large 7 or 5 gallon pots.

It’s important to use fresh planing mix in your containers each year. Heavy producers need fresh nutrients and deplete the soil by the end of the season. Also feed your containers for the best tasting fruit and vegetables and water on a steady basis. Skip a day of watering when larger plants are at their peak and you can lose your crop. There’s no such thing as dry-farmed tomatoes in a container. Growing plants is containers is low maintenance. No weeding required and one of the easiest ways to success.

April gardening tips, gardening tips, groundcovers, water saving techniques

April in the Garden in the Santa Cruz Mountains

Spring might have officially started mid-March but judging from the wonky weather it’s hard to tell. We did experience a ?Miracle March?? with a pretty good dose of needed rainfall along with some very cold weather. You never know what to expect in March around here.

But now we?ve turned the corner on spring with flowers bursting open within hours on these nice days. The Black-headed grosbeaks have returned to my yard for the breeding season. Like clockwork they show up on almost the exact day each year. It?s my version of the swallows returning to San Juan Capistrano.

Looking forward to the rest of spring, here?s what I?ll be doing around here in April.

Hopefully we?ll have plenty of April showers. This latest rainfall is surely? welcomed. One of the perks of a cool, rainy spring is that shrubs and perennials have longer to establish a good root system before hot weather arrives, ground covers have time to spread and shade the soil, conserving moisture come summer. What strategies can you follow that will make your garden low maintenance this summer and give you extra time to enjoy it?

Plant in masses. When designing or reworking your garden, make it

ajuga reptans, a groundcover for shady spots

easy on yourself by planting fewer varieties but in greater numbers. Planting this way will reduce the number of different maintenance tasks for that area. For example, if you have a large hillside that you want to cover, plant it with a groundcover like ceanothus gloriosus which fans out 6-15 feet. Some manzanitas like arctotaphylos uva-ursi eventually spread to15 feet each. Sage leaf rockrose and germander are also good for sunny areas. A shady spot could be planted with ajuga, creeping mahonia or Walkabout Sunset lysimachia.

Another time saving strategy is to group plants with similar moisture needs. This may sound like a no brainer but if you have just one prima donna in a bed of more drought tolerant plants, you’ll be dragging the hose over to that bed for just one plant or having to run your irrigation system more for it. If you find that some of your plants are not quite as low water as you’d like, move those to their own spot. In general, plants with large leaves usually require more water and transpire faster while drought tolerant plants typically have one of more of the following characteristics: deep taproots and leaves that are smaller, silver, fuzzy or succulent.

ceanothus ‘Carmel Creeper’ – A low maintenance, low water groundcover for sunny spots

Avoid putting thirsty plants in hard-to-reach places. If the irrigation system doesn’t reach that far, keep it simple by planting drought tolerant woody shrubs or perennials there.

Pluck weeds when the soil is moist and before they have gone to seed. Even if you don’t get the entire root of more persistent weeds, just keep pulling at the new growth. Eventually, the plant will give up having used up all of the food stored in its roots. I?m still battling hedge parsley with it?s sticky seed balls that will cling to my shoelaces and the dog?s fur if I don?t get it before it sets seed.

Plant edibles among your other plants near the kitchen. Tricolor sage looks great alongside other plants with pink and violet leaves. Purple basil planted below the silver foliage of an artichoke is another great combination. Lemon thyme growing next to a burgundy colored dwarf New Zealand flax would look spectacular, too. And don’t forget to plant decorative and delicious Bright Lights swiss chard with its stalks of yellow, orange, pink, purple, red, green and white throughout your beds. It?s one of the easiest vegetables to grow.

So get the lemonade ready to enjoy all your free time later this season.
