July growing tasks (Southeast – zone 7B)

July is just around the corner and it’s time to start thinking about the fall garden if you can believe it! Here in the SE, we are blessed to have two growing seasons if the timing is planned right.

THINKING ABOUT WHAT YOU WILL PLANT FOR YOUR FALL CROP AND WHEN TO PLANT IT:
All it takes to maximize your growing season is to know when your frost dates are for spring and fall. You’ll want to google what your last frost or freeze date is for your area. There is the traditional Farmer’s Almanac you can use, or I like Dave’s Garden’s resource as it gives a range of dates based on statistical data of when the first and last frost date has occurred. You’ll want to check this date each season prior to planning when to start your seed. I tend to lean on the 30-40% dates as my target date to plan off of and watch as the time gets closer. For our purposes, we will be looking at a freeze possibly happening between Oct 16-Oct 20, so I’ll split the difference and use Oct 18th as my first frost date and count back from this date based on the number of days (found on seed packet) for the plant will reach maturity and add in a 20 days for the plant to produce and bring a harvest in before a cold snap hits.

FINAL PLANTING OPPORTUNITY OF WARM SEASON PLANTS:
If you are growing in the southeast (we are in Atlanta in planting zone 7B), plant the following vegetables no later than July 20th to allow time to mature before frost: tomatoes, okra, corn, pole beans, lima beans, cucumbers, squash and snap beans. If you have a sucker growing on one of your existing tomato plants, now is the time to start a new tomato plant which will continue to grow and fruit until hit with a freeze. Toward’s the end of July, start your final crop of snap beans as these can be planted by August 15 as seedlings into the garden for fall harvest.

Now is the time to also plant Zinnia seed. These heat loving annuals sprout in six days and bloom in a few weeks in the heat of the summer. Plant more Caladiums and Coleus as they’ll look better in the fall than the plants often started in May.

You can also plant another crop of Gladiolus for another flush of blooms for summer and into fall. Now is also a good time to divide Daffodils using caution not to cut into the bulbs as you dig into the ground.

AN EASY TASK TO LIMIT PESTS AND DISEASES:
As you are harvesting your crops and cleaning off any dead leaves or removing leaves that have been attacked possibly by insect pressure, be sure to place these leaves in a 5 gallon tote to toss at the end of the day. You don’t want to leave dead leaves on the ground next to your growing plants as they will attract insects and promote disease which can transfer to your healthy growing plants. Keeping the ground around your plants tidy is a simple way to keep your plants thriving through the growing season.

CONTINUE TO FERTILIZE:
For annuals, you’ll want to continue to fertilize at two-to-six-week intervals. When using granular products, make sure to water afterwards to encourage the nutrients to filter down to the root zone of your plants. For soil, you can use “organic” fertilizers like manure (cattle or chicken), blood meal, and/or fish emulsion. Dr. Tim Smalley, horticulture professor at the University of Georgia, has shown that composted hen litter continues to release food for four years after a 2-inch layer is worked into flower beds. Patio tomatoes (in a container) need to be fed consistently because constant watering rinses fertilizer out of the soil.

WATERING PLANTS:
Be sure to keep tabs on watering soil-based plants. If you have had a good heavy rain, your watering tasks are probably eased for the day, but if it hasn’t rained, you’ll want to make sure you water deeply as needed to prevent drought stress. You can prevent root rot by watering deeply once per week and mixing plenty of organic amendments into the soil before planting and adding mulch to the soil surface beneath growing plants.

For plants growing in a hydroponic or aeroponic vertical gardening Tower Garden system, be sure to check your reservoirs at least twice a week as things warm up outside. If you’re growing tomatoes, tomatillos, eggplant, squash, kale, or beans, you’ll want to check your reservoir daily (or every other day) and top off the reservoir and add nutrients as these are “heavy feeders” meaning they take up a lot of nutrients when they are producing fruit, veggies, or legumes. Even though you are adding water to your system, it will be substantially less than the soil-based garden as hydroponic growing trials have been shown by NASA that these growing methods grow plants three times faster and produce 30% greater yields on average while using only 10% of the water a traditional soil-based garden would use to grow the same food. 

INCREASE PLANT PRODUCTION:
As your bush beans are growing, be sure to pick each day to encourage growth and plant output. Same is true with tomatoes… as they begin to ripen, pick often to encourage further fruit set.

PUMPKIN PLANTING TIME:
Plant that big pumpkin for Halloween this month and give it plenty of room to sprawl. If you have a fisherman in your family, save a fish head and toss in to the hole before planting your pumpkin seedling into the ground.

JULY PLANTING CALENDAR:
And finally, here is a quick cheat sheet you can print off and reference for what you can plant each week through either direct sowing (DS) into the ground or sowing indoors (SI).

The key to tasty salads is incorporating a mix of lettuce varieties. The vertical hydroponic Tower Garden is perfect for packing in 28 plants within a 2.5′ square footprint. This article focuses on spring planting, but you could grow any of these plants year-round if you have purchased the light attachment for your Tower Garden keeping the indoor environment around 70ºF.

There are certain greens that do really well in colder weather and can grow in early spring after the danger of frost has passed. Here is zone 7b, we will be starting greens the first week of March to be ready to go outside the last week of March. (Will use a Weather Protection Blanket each night until Frost Date of April 12.) It’s better to not have to store seeds for longer than a year or two, so we tend to purchase from this seed provider (Seeds Now), because of the smaller quantities and lower prices. The lower cost of seeds also enables us to try more varieties to see what we like the best.

How to Read Your Plants and Reduce Problems in your Hydroponic Garden

Do you understand what your plants are trying to tell you?

Just like a newborn baby cries for what he/she needs — a plant will exhibit signs of distress, but they do so silently, communicating with visual cues, such as altered leaf colors and shapes.

Just like a new parent, if you learn to read these signs, you’ll be able to catch minor issues before they become big problems, thereby maximizing the productivity of your garden.

So here’s a lesson in plant language 101.

Quick Reference Guide to Secret Plant Signs

If you notice a problem in your garden use the following chart to help determine what your plants need.

Tower Garden Tip: Nutrient deficiencies, plant diseases, and other common growing problems can occur at the same time and look similar, so identification may be tricky. If you need help, take a sample of the affected leaf to your local cooperative extension office. If you live in the state of Georgia, here is a quick link: http://extension.uga.edu/county-offices.html

Want to learn more about what your plants are trying to tell you? Let’s dive a little deeper…

Yellow Leaves and Nutrient Deficiencies

“Why are my plant’s leaves yellow?”

If you’re like most gardeners, you’ve faced this befuddling question before. Leaf yellowing — known as “chlorosis” in the world of science — has many potential causes. But one of the most common is undernourishment.

For healthy development, plants require 16 different micronutrients and macronutrients. And if they don’t get them or if proportions are imbalanced, leaves may start to look strange, become more susceptible to disease, and slow (or even stop) their growth — decreasing yields.

Symptoms of Plant Nutrient Deficiencies

Before you can address a deficiency, you’ve got to be able to figure out which nutrient your plant needs. So here are a few ways a plant may show you it’s missing something important:

  • Boron – Young leaves turn light green and may be disfigured.
  • Calcium – Leaves are disfigured and may wilt or show signs of necrosis (i.e., death of plant tissue).
  • Copper – Leaves may be limp and/or curled.
  • Iron – New leaves turn a pale, yellow color between green leaf veins (this is known as interveinal chlorosis).
  • Magnesium – Leaves show spotting and yellowing between green leaf veins. Outer edges of leaves may pucker or curl.
  • Manganese – Younger leaves turn yellow between veins (giving them a net-like look) and may develop dead spots.
  • Molybdenum – Older leaves yellow. Remaining leaves turn light green. All leaves may become distorted and narrow.
  • Nitrogen – Older leaves and veins turn a pale, yellow color. Other leaves turn light green and stay smaller than normal.
  • Phosphorus – Leaves looks stunted and turn dark green or even a deep purple color (almost black for some plants). Leaf tips may look burnt.
  • Potassium – Older, lower leaves show marginal necrosis, even looking scorched around the edges. Leaves also yellow on edges and between veins.
  • Sulfur – New leaves yellow and leaf veins lighten while older leaves remain green. (May be confused for a nitrogen deficiency.)
  • Zinc – New leaves yellow and may develop necrosis between veins.

For further help with identification, check out this visual representation of deficiency symptoms.

How to Fix Nutrient Deficiencies

The best way to solve deficiencies is to avoid them in the first place by giving your plants the nutrients they need.

For soil-based gardeners, that means using fertilizers, rich compost, and other amendments. But if you’re growing with Tower Garden, all you really need is Mineral Blend — a simple, balanced mix of all the key nutrients.

Tower Tip: Even if you’re providing the essentials, a high or low pH may keep plants from absorbing or processing them. Most plants access nutrients best when pH is around 6.5. So measure your levels every few weeks and adjust as necessary.

Other Causes of Discoloration and Disfigurement

Nutrition isn’t the only reason a plant’s leaves may look unusual. Here are a few other common causes.

Pests and Plant Diseases

It’s wise to watch for garden pests. Because bad bugs not only damage and stress plants — they also often introduce the following types of plant diseases, which bring additional harm:

  • Bacteria – Bacterial diseases can cause wilting and spotting.
  • Fungi – Some leaf fungi mimic certain symptoms of nutrient deficiencies, including yellowing and necrosis.
  • Virus – If you see blotchy or patchy yellowing on your leaves, a virus may be the responsible (especially if the discoloration is accompanied by disfigured growth).

Learn how to prevent and control these diseases »

Over (or Under) Watering

One of the most common, non-nutrient-related causes of yellow leaves is over or under watering. It’s a common cause, that is, for soil-grown plants.

Since Tower Garden automates the watering cycle, plants always receive the optimal amount of water. But if you’re growing in soil, here are a couple of ways to determine whether you should adjust your watering schedule:

  • Check the soil. (I know — it’s basic. But it’s never a bad idea.) If it’s drenched, it may be waterlogged, robbing plant roots of the oxygen they need to survive. In this case, water less.
  • Look for dropped leaves. Plants that don’t receive enough water drop leaves to prevent transpiration (i.e., the evaporation of water from plant leaves). So if you see leaves on the ground, water more.

Environmental Factors

Your growing environment can impact how your plants grow. Here are a few elements to consider.

Light
When accompanied by thin, reaching stems, pale leaves usually suggest a plant isn’t receiving enough light. (Most plants need at least six hours of direct sun or, if growing indoors, 14 hours under grow lights.)

On the other hand, newly transplanted crops may develop bleached spots on their leaves after too much sun exposure. To avoid this, harden seedlings by gradually introducing them to the outdoors over the course of a few weeks.

Similarly, when growing inside, leaves that get too close to grow lights may become spotted or scorched due to over-transpiration, which is followed by yellowing, spotting, and, eventually, leaf death. The solution? Harvest more often!

Nutrients
To prevent wilting in a Tower Garden full of small seedlings (e.g., plants that are three inches tall or shorter), it’s best to use a half-strength nutrient solution: 10mL of Mineral Blend A + 10mL of Mineral Blend B per gallon of water.

You can safely increase nutrients to the full amount once seedlings have grown taller than three inches and developed a robust root structure. This usually takes less than a month.

Note: Even for mature plants, overly concentrated nutrients can also cause fertilizer burn. So make sure you’re always feeding your plants the proper amount.

Temperature
Extreme heat often causes plants to wilt. But they usually bounce back once temperatures cool. That being said, these precautions can help protect your plants from hot weather.

If you notice black spots on leaves or plants after a cold snap, frost damage is likely the cause. Some plants — particularly kale, collards, and other hardy greens — can survive light frosts. More sensitive crops, such as tomatoes and peppers, however, usually die after freezing weather.

Wind
If leaves look dry around the edges and/or curl upward, they may be suffering from windburn. Consider setting up a wind barrier to protect them.

Time
It’s completely normal for older, more mature leaves of a plant to yellow and die over time (as long as new, green leaves are replacing them). Just remove these old timers as you see them to prevent leaf fungi.

What Are Your Plants Saying?

Now that you know how to decode your garden’s secret language, diagnosing and rectifying problems should be a little more straightforward.
