What's happening in the late April garden

Spring in the park

Sunday, April 26, 2015

It was unusually cold through the end of February and March this year in our Zone 6/7 garden.  Things are not popping out of the ground like they were last year.

So, what is popping up?  Overwintered garlic, Elephant garlic, French sorrel, blood veined sorrel, kale, sprouting broccoli, dandelions, common chives, garlic chives, strawberries, onions, wild leeks, sage, mint, thyme, newly planted Oregon sugar pod peas and overwintered Austrian pea shoots.

We added compost, fertilized, and mulched the garden beds and pots at the end of March.  It is not too late to prepare your beds and plant cool season veggies right now.  You can plant a summer garden right through June. 

Lowes, Home Depot, and Ace all have bedding veggies in stock.  Of course, I couldn’t resist!  I bought broccoli, rosemary, oregano, lavendar, snapdragons, alyssum, petunias, chard, buttercrunch and romaine lettuces. I am in love with the red and burgundy varieties! I grew from seed and planted Tuscan kale, sugar snap peas, mesculun greens, several heading broccoli, sprouting broccoli, 9 Star perennial broccoli, Golden Streaks mustard, pole beans, oregano, parsley.   Outdoors I sowed seeds of various lettuces, spinach, carrots, beets, culantro, cilantro, and Fordhook Swiss chard.   

For outdoor sowing, I have a few elongated pots that I start my seeds in. This was I can get them at the perfect depth.  I put labels in each so I don’t forget.  When they are up and have a few leaves, I will transplant into larger pots or the garden.  I plant my veggies in my mulched garden beds.  Most seedlings can’t press through the mulch.  The other thing I like about having sprouting pots is that I am not wondering if it is a weed or something I planted!

I am still starting summer loving veggies, fruits and flowers indoors.  The Aerogarden, a hydroponic system, is great for this.  Just planting in re-used 6 packs on a heated mat does fabulous as well.  I am using both at the moment.

I plant a few annual herbs and any tender perennial herbs that didn’t survive the winter each year.  Annual herbs-cilantro, culantro (heat tolerant herb that tastes like cilantro), basil, parsley, dill and tender perennials-rosemary and bay are mainstays.

The cilantro does not last long; as soon as it warms up, it bolts.  You have to succession plant these to keep them in the garden.  Place them in a cool spot that gets some morning sun, but is in the shade the rest of the day.  Culantro has the taste of cilantro, but does not bolt.  Keep it in the shady part of the garden for the fresh taste all summer long.  Parsley and dill typically re-seed themselves so I wait until May before I replant these annuals.  

Most Mediterranean herbs are perennials like thyme, oregano, tarragon, sage, lavender.  Bay can survive in Zone 6 if the winter is mild.  There are varieties of rosemary rated to Zone 5, but I have never had mine come back for a second year.  Basil is very cold tender and must be replanted each spring after all danger of frost has passed.
Tarragon to left, garlic chives in center and common chives on right, getting ready to flower

Chard is a decorative and hardy green that comes in such beautiful colors-orange, red, yellow, burgundy, fuchsia and white stemmed varieties.  I planted them all along the back of the garden bed one of each color from the little flat of seedlings.  

Small chard leaves are great in salads.  Large leaves are great steamed.  The stalks of the large leaves can be used like celery, but very pretty celery!  Chard is a tender perennial.  The white stemmed Fordhook Swiss Chard is the most cold hardy. I think a pop of white makes the dramatic colors even more vibrant.   I had a red chard come back for years.  Chard produces a ton of seeds.  Save them from your favorite plants and reseed next spring.  Seed saving produces plants that are uniquely adapted to your garden conditions.

I like broccoli raab or sprouting broccoli because you get small broccoli heads throughout the entire growing season versus one large head at once.  The leaves are also edible and great to add to salads.  They grow to be large plants.  Two plants gave us all the broccoli and broccoli leaves we needed for our salads.  If planting in a container, thin to one plant in a large pot.  My overwintered purple sprouting broccoli already has florets!  I started 2 new plants from seeds I saved from a couple of summers ago.  They are filling out nicely.

Now is also the time to plant spring garlic.  Fall is the best time, but you can get scapes and small cloves by planting in spring.  My elephant garlic is going strong.  When you dig the garlic in the fall, there are tiny cloves that usually get left behind.  These will come back in the spring.  The tiny cloves may take 2 seasons to get up to full size cloves.  I have garlic resprouting from these tiny bulbets left in the ground after last year’s harvest.

The lettuce I planted at the beginning of March has leaves large enough to harvest.  The sprouting broccoli, dandelions, sorrel, pea shoots are all great adds to spring salads.

Nutrition, types and tips for growing carrots


Wednesday, April 22, 2015

Carrots are rich in antioxidants, beta-carotenes, vitamin A, vitamin C, many B-complex vitamins like folic acid, B6, thiamin, pantothenic acid, as well as minerals like calcium, manganese, phosphorus, potassium, copper.  They are super easy to grow.
Carrots, like turnips, have been around for thousands of years.  Its seeds were used for medicinal purposes.  Carrots likely originated in the Iran/Afghanistan area and spread to the Mediterranean.  It is shown in Egyptian tomb paintings from 2000 BC. The first records that it was used for the European kitchen was in the 900‘s in Spain.  Carrots were originally used mainly for livestock feed in the American colonies and for its aromatic leaves and seeds.
The first wild carrots were purple.  The wild carrot is known as Queen Anne’s lace and adapted very well in America.  The popular culinary orange colored variety did not become stable until the 1700’s.  It quickly became the most popular variety in both Europe and the colonies.  
Carrots are related to parsley, fennel, dill and cumin.  Like their cousins, the greenery also is edible.
Carrots like loose, well dug soil rich in organic matter although they will also grow in moderately rich soil.  The ideal soil would be dug 6-10” deep and mixed with sand and compost.  The longer the root, the deeper the depth of loose soil needed to grow large, straight roots.
There are also shorter root varieties that can be sown if you do not want to dig that deeply or if you want to grow them in pots.  Some short varieties are Little Finger (4” long), Adelaide (the size of your pinky), Short n Sweet (4”), Thumbelina (1-1.5” diameter), Parmex (1.2-2” diameter), Tonda di Parigi (1.5-2” diameter).
Sow every 2 weeks March-July.  First plantings should be about 2 weeks prior to your first frost.  Carrots do not like to be transplanted so direct sowing is best.  Soak seeds 6 hours before sowing.  Sow 1/4” deep, 1/2” apart thinning to 2-4”.  Keep evenly moist, do not allow to dry out, for the up to 14 day germination period.
For your last plantings of the season look for a type like Autumn King or Nantes that can be harvested throughout the winter.  Merida can be planted in late September for an early spring harvest.  Frost actually makes the carrots sweeter so leaving them in the ground in the fall will improve their flavor.  All kinds of colors are now available-white, red, orange, yellow, and purple.
If you want to bring indoors to store, placing in a cool place in sand that is kept moist is the best indoor long term storage for the winter.

Spring salads-Yum!

Early spring mixed salad greens

Sunday, April 19, 2015

Springtime is the prime time for the freshest, crispest, tastiest salads of the year.  There are so many options for salads.  The vast majority of greens have something in common-they are the sweetest in the cool, moist days of spring. 

There are many perennial greens that are going strong this time of year.  Salad burnet, garden sorrel, chard, blood veined sorrel, over wintered sprouting broccoli, cultivated dandelions, arugula, overwintered spinach, Giant Red mustard are of harvestable size this time of year.  You can add the early herbs for zest like garlic chives, common chives, tarragon, sage, oregano, leeks, and onions.  If you started lettuce indoors or bought a multipack earlier, you will also have lettuce leaves you can add.

Multipacks are a great deal.  I've seen 9 packs for less than $2 and they have many fun and heirloom varieties too.  I am loving the red varieties.  They have even more nutrition than just the green.  The same antioxidants that blueberries have.
Blood veined sorrel and parsley
Greens are fed by nitrogen (stimulates green growth) and stay sweetest in cool temperatures with consistent moisture.  Like most vegetables, greens do best in a fertile soil, rich in organic matter.

You can accomplish this through adding compost to your garden bed or container with a balanced fertilizer and blanketed with a mulch covering.  Planting or positioning your container in a spot where it gets some sun, but good afternoon shade to keep the plant cool will prolong the sweetness of the leaves.  You can also use a shade cover to keep the plant and soil temperature down.  Greens do not need much sun in the summer since there is so much reflected light available to the plant.

You don’t want the soil to dry completely out.  This will stress the plant and stimulate it to go to flower, or bolt as they call it.  Keep the soil moist.  Mulching is a great way to keep the soil evenly moist.  It also adds organic matter and suppresses weeds.  Just make sure if you are planting in mulch that the plants roots are fully in the soil.

Picking right after a rain or first thing in the morning also gives the sweetest, plumpest leaves.  Harvest leaves from the outside of the plant.  Lettuce and other greens will continue to produce leaves from the inside.  Your harvest amount and length will significantly increase doing this versus cutting the entire plant for a single harvest.

To wrap it up:
1.  Plant in rich soil.
2.  Use a natural fertilizer high in nitrogen (coffee grinds work well) each time you seed or plant.
3.  Keep the soil evenly moist; don't allow to dry out completely.  Planting in self-watering pots and applying mulch can help.
4.  Successive sowing of lettuce and spinach seeds.
5.  Keep the plants in a cool, shady location to extend the harvest in the summertime.
6.  Harvest outer leaves to let the inner leaves continue to grow.
7.  Be creative!  With so many fun options out there, try some new salad combos this year.

Decorative container gardening for edibles

Pepper plant with petunias

Saturday, April 18, 2015

There are so many new varieties out every year.  There are ones that are more resistant to disease.  Ones that have higher nutritional value.  Ones that produce more.  Ones that have improved taste.  Ones that are developed for their small size and big harvests for those of us who have limited space or just want to get more for the effort.  It is amazing what can now be grown in pots!

We hear a lot about Monsanto and GMO’s (genetically modified organisms) and crop breeding can seem a bad thing.  The difference between GMO’s and other types of crop breeding is that GMO’s bring in genetic material from other organisms in a lab, like bacteria and even viruses.  The plants are engineered so that they kill insects that try to eat it.

That is only one side of the plant breeding story.  There are many other natural, with a little help, breeding of crops today.  It can be as simple as saving of seeds from the best producer of last year.  There are also hybrids which take the best traits of two different parents into seeds.  These hybrids will not produce seed that you can reuse next year and get the same vegetable as the parent.

Heirlooms and open pollinated vegetables will produce “true” to seed.  The offspring will be like its parent.  It isn't just the old varieties that you can save and use seeds from year to year.  It is any "open pollinated", non-GMO, non-hybrid.  If you find a veggie you really like at the store, it doesn't hurt a thing to save the seed and try growing it in your garden.

Through the centuries, farmers have chosen the traits they like and have built on them from season to season.  This has given us Brandywine tomatoes, Vidalia onions and Jalapeño peppers.  Yum!

Today's breeding has focused on urban gardening; growing great tasting fruits and vegetables in small spaces and containers.  There are lots of new compact, dwarf, bush, patio, container varieties available every year.  Today, you can grow almost anything you like in a pot, even corn and watermelons!

Just be sure to match the right edible with the size of pot you have.  Add flowers, too.  This not only adds pizazz to the container, but attracts beneficial pollinators that increase yields.  A real win-win.

What size pot do you need for a container veggie garden?
Any varieties listed for a smaller pot will be happy in a larger pot, too.  There are many more varieties out there than listed below.  Just look at the seed packet for terms like patio, compact, or dwarf.  Here are suggestions by size of pot you have.

For containers 8” wide by 6-8” deep:
Carrots-Thumbelina, Parmex, Tonda di Parigi 
Greens-arugula, corn salad, cress, small pac choi like Tatsoi, purslane
Lettuce or Kale-any type that you are going to continually harvest and not grow into full heads.  


5 Day Golden Cross Cabbage

For containers 10” wide by 10” deep or larger, these will grow well:

Tomatoes
Watermelons
Winter squash-Honey Bear, Carnival, Discus Bush Buttercup

Black Beauty eggplant with fuchsia petunias and Egyptian walking onions

When growing veggies and fruit in containers, they will require more watering and more liquid fertilizer than if they were in the ground.  In the summer, you may have to water some water lovers every day.


To reduce watering, purchase or make pots that have a water reservoir in the bottom.  A couple on the market today are “Earthbox” and “Grow Box”.  With these type of pots, you can water weekly.  

You can make your own self-watering containers using 5 gallon buckets or other plastic containers or you can buy a self watering kit to convert your existing container to a self watering pot.


With all the colors and varieties out there, beautiful container combinations can expand and beautify your garden space.

Want continuous harvests? Succession planting!

Succession seed starting in pots

Sunday, April 12, 2015

A key strategy to getting the most out of your garden space and harvests is to leverage succession planting.  Never have an empty spot.  Be ready as soon as you harvest one plant or crop to fill the space with its replacement.  When you do plant, don't plant all at once so that your plants come to maturity one after another versus all at once.  And plant different varieties with different maturity dates.  All these strategies will significantly boost how much your garden gives you!

Planning is key.  You will need to lay out your garden bed by each season so you can see what you need when.  As soon as the cool season crops like lettuce, beets, spinach, radishes and carrots are spent, it will be time to replace them with warm season crops like beans, tomatoes, peppers, eggplant, and squash.

To lengthen the harvest of each vegetable, you should also stagger your planting through the season.

Here is a list of succession planning by vegetable for continuous harvests:
Beets-every two weeks
Bush Beans-every two weeks
Pole Beans-give continuous harvests naturally
Broccoli-best accomplished by planting types with different maturity dates
Cabbage-best accomplished by planting types with different maturity dates
Carrots-every 2 weeks
Cauliflower-best accomplished by planting types with different maturity dates
Chard-give continuous harvests naturally
Corn-best accomplished by planting types with different maturity dates
Cucumbers-once after last frost and then 2 months later
Eggplant-give continuous harvests naturally
Lettuce-every two weeks (be sure to switch to heat tolerant varieties a month after your last frost)
Peppers-give continuous harvests naturally
Radishes-every week
Spinach-every two weeks until last frost
Tomatoes-best accomplished by planting types with different maturity dates; indeterminate varieties give continuous harvests naturally
Zucchini-once after last frost and then 2 months later

Another thing to keep in mind is how much a plant produces. Some vegetable plants will give you continuous harvests and some will give you only one or two vegetables (like corn).  Dwarfs are also a great idea for small garden spaces and containers.  Here is more on maximizing harvests:  This year's garden plan and How do you decide what to plant for small spaces??

Happy, productive gardening!

Indoor sowing/outdoor planting dates



Saturday, April 11, 2015

Johnny’s Seeds has some great tools on their on line web page.  They also have an excellent variety of seeds, including organic, Italian and heirloom.  I ran across this calculator for when to start seeds indoors and transplant outdoors for vegetables and flowers.


Here is the table for our frost free date of April 20th.  You can sow seeds outdoors on the same timing as you can transplant your seedlings outdoors.
