What to plant in the June edible garden

Potted eggplant with petunia
Sunday, May 28, 2023

In our Zone 7 garden, June is summer; highs in the 80's are here to stay.  The cold crops planted in April like lettuce, mustard, kale and spinach are bolting (gone to seed).  The tomato transplants are blooming and three varieties have a baby tomato growing.  The bean vines I planted last month are 2.5 feet tall.  I just transplanted the squash and cucumbers into their summer pots and garden bed.  If planted earlier, they would all be flowering with baby fruits on them.  This year, I started my summer loving  peppers, basil and eggplant from seed late.  No worries, these heat lovers will grow quickly in the summer sun.

I transplanted my seedlings of basil, rosemary, a couple more tomatoes, eggplant, salvia, and sweet peppers from peat pods to 4" pots this week.  I started them indoors early in the month and moved them outside for a few days before transplanting them into 4" pots.  Some still have only their seed leaves and a few have their second and third set of leaves.  I'll transplant them out into the garden and large pots in another couple of weeks.  I plant my eggplant and peppers in pots.  The basil, salvia and tomatoes will all go in the garden bed.

I'll continue growing lettuce from seed about every 3 weeks to keep sweet leaves going for harvest.  I do love salads.  I have done a couple of rounds of wildflower seeds in a rectangular growing pot next to the patio.  After the seedlings are a nice size, I transplant into my pollinator garden bed.  Other than lettuce, I don't have plans for any more seeding for a month or so.  Late July is the time to start fall veggies from seed.

Below is a list of plants and seeds you can put in the June edible garden.  Transplants give you a jump on harvests and are still available at big box stores and nurseries, but seeds are inexpensive and you can get unusual varieties to try that you can't get as transplants.

I love to have fresh salads every day.  It is tough in summer to keep the traditional salad greens like lettuce and spinach going in the hot weather.  I sow seeds every 3 weeks in spring to keep greens going.  Go for the bolt resistant types in late spring and early summer.  Bolt-free, sweet summer lettuces  I have also in recent years started planting substitutes for lettuce and spinach.  

For lettuce substitute, I am growing sprouting broccoli and a sweet Chinese cabbage, Hilton, along with orach, multi colored amaranth, cultivated dandelion greens, arugula and chard.  All can be sown now.

For spinach substitutes, I am growing Perpetual Spinach, Red Malabar spinach and New Zealand spinach.  They all thrive in hot weather.  Malabar spinach is a vine so give it a trellis to climb.  It is quite pretty with its maroon stems and flowers.

Give your greens the coolest spot in the garden and moist to keep them sweet and succulent.  You can use taller plants to give them shade as well.  Growing summer salads

For tips on starting your seeds in the garden:  Outdoor seed starting tips  I also like to put a pot or two on our covered deck and start seeds there.  Once they are to a good size, transplant them into their permanent pot or into the garden bed.  Be sure your seedlings are hardened off as the heat and sun can be intense this time of year. "Hardening off" seedlings   I like to plant on a cloudy day when rain is being called for the next day.

In June, the days are getting hot and the rains don't come as often.  Be sure to water your new plants when it gets dry or they wilt.  Summer garden tips

Native fruits and vegetables

Tomatoes are a native of the Americas

Saturday, May 27, 2023

With global access to seeds and plants these days, it is difficult to tell what are native to our area, region, continent and what was brought here over the centuries.  The difference between "native" and "heirloom" is that an heirloom only needs to have been grown here for at least 50 years whereas native is a plant that originated here; some natives are thousands of years old.

We don't have many native fruit trees in North America; most of our popular fruit trees were brought over as folks immigrated from Europe and other parts of the world. Black cherry, American persimmon, mayhaw, farkleberry and pawpaw trees are natives.  Apple, pear, plum, lime, and lemon trees all hail from Asia and Europe.

We have quite a few native berries in North America.  Strawberries, blueberries, cranberries, red and black raspberries, serviceberries, North American grapes (like Concord and mustang), loganberries, gooseberries, elderberries, chokeberries, buffalo berries, and huckleberries. 

There are many globally popular vegetables that originated in the Americas.  America's favorite garden vegetable, tomatoes, originated in South and Central America.  Other natives include maize (corn-Mexico), beans (Central and South America), squash (Mexico and Central America), avocados (Mexico), peppers (Central or South America), potatoes (Peru), tomatillos (Mexico), sweet potatoes (Peru), peanuts (South America).  A couple of grains that are native are wild rice (Great Lakes) and amaranth (South America).  All of these crops spread across North and South America thousands of years ago, well before European explorers came to the Americas.

Peppers, a native of the Americas

Some were taken back to Europe from the Americas and cultivated widely before being brought back to the colonies.  Great examples are the tomato and potato.  We associate potatoes with the Irish and British and tomatoes with Italy but their origin was actually in the Americas.

There are several edible greens that are native to North America like ramps, lambsquarter, wild onion, wild garlic, and fiddle leaf fern but are not commonly cultivated in the garden.  They are packed with nutrition so great to add to salads.  The greens of amaranth can also be used as a summer substitute for lettuce.  

What's happening in the mid May edible garden

Potted lettuce

Saturday, May 20, 2023

Everything is lush and green this time of year.  The edibles are growing quickly.   Salad fixings are in their prime with the summer edibles just getting started.  Herbs are filling out nicely.  By this time of year, we no longer need to purchase produce from the grocery store and can get fresh herbs to add to dishes that make them taste wonderful.

The greens we are eating-French sorrel, spinach, dandelion greens, winter cress, arugula, chick weed, sweet clover, Egyptian Walking onions, celery, Ruby Streaks mustard, Chinese Giant Leaf mustard, sprouting broccoli leaves, orach, many varieties of lettuce and snow peas.  Many are overwintered or volunteers from last year.  I also started different varieties of lettuce and bought a few transplants from the store.  I like to have new lettuces coming on all the time so there is always plenty for salads.

Herbs to add to dishes and salads-garlic chives, regular chives, oregano, thyme, horseradish, Egyptian walking onions, tarragon, sage, young garlic, cilantro.  All are perennials or self-sowers so they come back year after year.

The fruits and veggies-wild strawberries, cultivated strawberries and carrots.  Strawberries are perennial and carrots overwintered and came up from last year's seed.

The flowers that are blooming-irises, spiderwort, roses and petunias.  The herbs and veggies going to seed-yellow flowers of the sprouting broccoli, mustard and cress, yellow dandelion flowers, lavender chive flowers.  Soon, the beautiful purple flowers of sage, the white flowers of thyme, and the white garlic chive flowers.  All veggie and herb flowers are edible.  A fun way to add flavor and beauty to salads or other dishes.

The overwintering and early spring planted lettuce is beginning to bolt so soon there will be the white, yellow and blue flowers from the different kinds of lettuce.  Several carrots are starting to bolt, too.  If not pulled, they have beautiful white flowers resembling Queen Ann's Lace, which they are from the same family, that bees love.

The white and pink peonies and lilacs have already come and gone.  They both were heavy with flowers this spring.  

This week, I weeded I transplanted and fertilized.  I planted out 11 tomato plants and am moving perennials from one bed to other beds.  I tried starting seeds outdoors in pots in April but then was gone most of the month.  I restarted the tomatoes, peppers, basil, eggplant, sage, squash and cucumbers indoors.  They have sprouted.  I'll start moving them into larger pots when they get their second set of leaves.  The cucumber and squash seedlings, I'll transplant into their permanent spot when they get their second set of leaves. I had started beans a few weeks ago in outside pots and they are about a foot tall now. 

It is a good idea to wait 10 days after planting new plants before you give them much fertilizer.  I'll add a diluted liquid fertilizer to all that have their first set of true leaves in the next week.  When I transplant them, I will add char, worm castings and starter to each planting hole.

It's okay to just be getting started in the edible garden with the summer lovers.  You can plant a summer garden into June and still have a nice harvest.

 

I have also have very enterprising voles in the garden.  The good part of this is that they do a great job of loosening up the soil.  The bad part is that if there tunnels go under your plant, there is a good chance, the plant will die.  I've tried electronic deterrents.  Not sure how well they worked.  Voles love mulched areas.  I don't get any in the beds with decorative gravel.  I read recently that they don't like coffee so I may try putting coffee grounds in their tunnels.

Volunteer Red Malabar spinach and Chinese Multicolor amaranth

I have been harvesting the greens by taking only the outer leaves so that the plants will continue to grow.  By harvesting, it stimulates the plant to grow even more leaves.  If you have extra greens, besides lettuce, you can blanch and freeze them.  I still have plenty left in the freezer.  Preservation garden

I am doing good right now on lettuce, but will need to start some more seeds in a couple of weeks.  If you start seeds every 2-3 weeks, it keeps you in lettuce all the way until winter.  This time of year, start the heat tolerant varieties.   I have also moved to using greens that stay sweet during the dog days of summer.  The greens I have found so far that are great lettuce and spinach substitutes in salads are Red Malabar spinach, New Zealand spinach, Perpetual Spinach chard, Chinese Multicolored amaranth, all colors of orach, Chinese Hilton cabbage (doubles as a great wrap, too), sprouting broccoli.  Keep salads going all summer long.

Why and when does lettuce turn bitter?

Potted lettuce "bolting"

Saturday, May 6, 2023

I love fresh salad and when the garden is giving, I try and eat them every day.  In our zone, it is hard to keep lettuce going that is not bitter once the hot temperatures arrive.  What causes this, when does this happen and what can you do about it?  This challenge is something I work on each season to have a way to keep sweet lettuce or other type of salad green producing all summer long.  Here is what I have learned so far.

When does lettuce leaves turn bitter?  In my garden, this starts as soon as we start having days that the high temperature hits the 80's for sure.  

What causes lettuce leaves to become bitter?  Lettuce starts turning bitter when it begins to make a flower stalk to make seeds.  There are 2 triggers for this-warmer temperatures and drier conditions.  

What can you do about it?  Keeping lettuce with consistent moisture and moving the plants to a cooler part of the garden can extend the harvest.  Look for lettuce varieties that are "bolt resistant".  You can also do succession sowing so you always have young plants producing.

I grow most of my lettuce in a self-watering pot that has a reservoir of water in the bottom.  This really helps keep the moisture consistent.  When the temperatures start getting into the low 70"s, it is good time to move your pot to a cooler part of the garden.  Another option if you are growing your lettuce in the ground is to sow seeds in full sun in early spring, then move to sowing seeds in the cooler part of your garden bed.  When it is warmer, lettuce does fine in even dappled shade.

I always harvest the leaves from the outside of lettuce plant to allow the inner part of the plant to continue to produce more leaves.  Since there are only 2 of us, this lets me harvest from a plant very early and for weeks without any going to waste.  

When the leaves start to get bitter, I just let it go to seed.  I save some of the seed and let some take their natural course.  I try different varieties every season along with the ones that have so far proven to be the best producers for my garden.  I look for bolt resistance, varieties that stay sweet even after bolting and the best self-seeders.  I let the seeds fly where they want and then keep an eye out for volunteer seedlings.  I'll transplant them to where I want them after they get sturdy.

I do practice "succession sowing" which means I sow new seed every few weeks.  I sow seeds about every 3-4 weeks unless I am getting volunteers naturally.

I also plant other varieties of greens that like the summer heat and stay sweet to supplement my summer salads.  The ones that have done the best for me so far are Hilton Chinese cabbage (use for salads and wraps), orach (comes in lime green, green, rose and purple), a variety of amaranths that are ornamental as well as tasty (Chinese Multicolor Spinach, Love Lies Bleeding, Pink Beauty), Red Malabar Spinach (a pretty tropical vine), and sprouting broccoli.  All do well in my summer garden.

I keep trying different lettuces to find the lettuce that stays sweet the longest, even after bolting, in my garden.  So far, the best performers are Red Sails, Butter King, Marvel of Four Seasons, Royal Oakleaf, and Bronze Beauty.

New ones that I am trying this year are Giant Blue Feather, Yedikule, and Solar Flare for their bolt resistance.
