Growing Potatoes in Your Florida Garden

The time to plant potatoes is now!

Potatoes are a good way to usher in the growing season of your home garden. They are easy to grow and their harvesting date doesn’t coincide with many other vegetables. In North Florida you can plan to put in your potatoes around the end of January through February. It’s easy to grow red- and white-skinned Irish potatoes. Also, brown-skinned russet potatoes do nicely in the garden. However, before we get ahead of ourselves, the first step you need to take is preparing your soil and garden plot.

Since potatoes prefer a loose, well-drained, slightly acidic soil (pH 5 to 6), little needs to be done in many Florida gardens. However, potatoes do not grow well in flooded conditions. Care must be taken to ensure that the root zone has adequate drainage. To help alleviate flooding conditions, beds should be formed into mounds (hills) about 10 to 12” above soil level. It’s always a good idea to add in organic matter to your soil, this will provide nutrients and structure to your soil.

The potato tuber is the plant “part” required to grow a new potato plant. When a piece of the tuber is planted, it is called a “seed” potato. Only certified seed potatoes should be planted in the home garden. Certification ensures that the seed tubers are free of disease and viruses. Certified seed can be obtained from a number of reputable garden supply stores. Do not purchase potatoes from the grocery store to plant in the home garden. Potatoes from grocery stores are often sprayed with chemicals that inhibit sprouting and they can contain diseases that would be harmful to your garden. Also, remember to never store tubers in direct sunlight. Seed potatoes should be cut so that each piece is about the size of an egg with at least one eye per seed piece. Seed potatoes should be allowed to “heal” before planting; this will reduce the risk of rot upon planting.

Potato plants should be spaced at about 6–8 in. within the row with at least 36 in. between rows. Seed pieces should be planted with the cut side down and eyes (or sprouts) facing up. Due to the fact that the seed piece should be planted only 4 in. below soil surface, new tubers could emerge from the soil surface. These exposed tubers will turn green and inedible in the sun. Therefore, hilling is a necessary process in growing potatoes. Hilling is the act of adding about 2 – 3 in. of soil to the top of the potato row.

Potatoes, in Florida are generally grown during the drier times of the year. As a result, supplemental irrigation may be required to provide plants with an adequate amount of water. Moderate soil moisture levels should be maintained throughout the season. Just remember to never over water!

Most potatoes are ready for harvest between 80 and 115 days after planting. To harvest, carefully dig potatoes below the potatoes and remove them from the root system of the plant. Potatoes are best stored in cool, dark, well-ventilated locations. An important fact to remember when harvesting potatoes is to always avoid eating green potatoes. Green potatoes have high levels of a toxin called solanine, which has a bitter taste. It is toxic even at very low levels. Potatoes can “green” in the field, in storage, and at home when exposed to the light.

As always, if you have any question or need further information please contact your local extension agent!

Hi Sara, Thank you for your comment! Edible ginger, Zingiber officinale, is not considered invasive and can be planted in the soil or in a pot. Here is more information, including additional links about ginger, how to grow it, and how to harvest the roots: https://gardeningsolutions.ifas.ufl.edu/plants/edibles/vegetables/ginger.html Thank you and please let us know if you have any additional questions! Sincerely, -UF/IFAS Leon County Extension

Is edible ginger invasive or does it have a lot of spread (like Boston? ferns)? The ginger sprouted in a pot from buying a fresh organic root at the grocery store. Should I plant the ginger in my yard or keep it in a pot?

Love this and thank you for all the information you have shared. Such a great idea! I have already started my brush pile and hopefully, others will do the same and keep costs down and give the small creatures a place to harbor as well.

Thank you for this helpful article! I’m just really getting started with roses & I've learned a lot from this. I want to say how excited I was when I saw your picture of Belinda’s Dream. I had purchased one at Antique Rose Emporium several years ago but lost the tag. As soon as I saw your picture I knew it was my rose’s name! I also purchased Julia Childs - and I have a Jaden Cross Rose from Jim Herbeson. My husband built me a raised bed, just for roses. Can’t wait till it’s full & beautiful!! Thanks again

I keep trying to grow Confederate Jasmin on a trellis on north wall of east facing ocean balcony. It gets some wind protection. The plant keeps dying from what I think is white fly. I grew this outside in Coral Gables without problems. Any suggestions?

This blog was very helpful in that I'm new to the area from VA where tall fescue is king. Yard is primarily centipede; did some sodding last fall that died . Now I think I know why. Will get soil test conducted and perhaps go with St Augustine in the lightly shaded area, thanks.

It may be an urban legend, but I've heard that they irradiate or treat some ginger to prevent it from growing. I always look for fresh growth nubs on ginger if I'm looking for some for planting.

Hi Ann, Sorry for the confusion. What I meant to say is that while spinosad is safe in vegetable gardens, not all organic materials are safe. Rotenone and nicotine sulfate are examples of organic materials that are not safe in vegetable gardens. Does that help? -Molly Jameson

Must be in the same family as the cypress vine - it stinks too.

In paragraph six it states that spinosad is safe for use in vegetable gardens. And then in the same paragraph say it should not be used in a vegetable garden. I'm confused. Is it okay? I've tried everything. Digging it up. Boiling water. Cinnamon. Thanks, Ann

This is the best organic way of dealing with waste. I started researching compost opportunities while ago. This is the future if we want to keep the planet's environment and resources, of course. I didn't know much about vermicomposting, only about the standard composting methods. I know most people are used to hire a company for their waste removal needs but it is good if they consider at least to try your composting method. Thank you, Sheryl

I believe that proper and regular garden waste clearance could significantly reduce the risk of your plants getting affected by fungus and bacteria. It doesn't require much effort and if you don't have the time to do this by yourself you could always hire professional rubbish removal service.

couple of comments.....(1) As an organic farmer, mushroom compost seemed a no-brainer addition to my yearly mulch pile. However, I stopped using it a couple of years ago because of an article discussing the chemicals the mushroom folks use to reduce certain diseases peculiar to mushroom. (2) I also used straw bales to boarder three sides of my yearly mulch/compost pile and then at the end of the year incorporated the rotted straw into the compost as a "plant-based manure." However, a couple of years ago I came to understand that since straw is generally not consumed when used as a bedding material, straw farmers liberally sprays their fields with herbicides to improve the straw's "purity" from weeds Again, concerned with residual chemicals I discontinued using straw. Results from (1) & (2) = my raised-bed garden with 100% organic growing medium (no dirt) has yielded healthier plants and better crop yield. Took two years, with each year showing improvement. CONCLUSION: carefully "vet" the origins/history of the ingredients that go into your compost so you can more closely realize that garden of your dreams!

I've been growing container veggies on my deck for years. Some don't do so well and others are astounding! Tomatoes never did well for me in-ground, but large pots on the deck are perfect. Green snap beans, banana peppers and salad greens too. what few pests found are easily disposed of and soil borne troubles are nil. I will never go back to any other system.

The best time to plant potatoes here is in January/February. Also, russet potatoes are more commonly grown in more northern climes and generally not grown in Florida. See our publication on potatoes: http://edis.ifas.ufl.edu/pdffiles/HS/HS18300.pdf But you can give it a try and see what happens!

I live in the fountain area, and I know I will not have the lush green grass I had in Nebraska, I have problems in my yard I do not know what to do about. Yes I have lots of turkey oaks with white around them that seems to kill the tree after time. But my main concern is I will have a nice green patch of grass, but then the edges die. Sometimes a big circle will be there with just weeds growing in it. I also have a vine that goes underbeath the soil and kills plants I can get to grown. I also have a tree in my yard that almost has leaves like a mimosa but is bright orange in the fall. Can you heip. I do not know when to go to get answers for my questions

Food waste is a worldwide problem, but in the US it seems it is the most major issue, excluding hazardous waste... Recently many supermarkets began a program in which they use their waste to convert it into power and use that power. As a professional dealing with almost any kind of waste, household rubbish and house clearances in London, I can really say that now is the time to make innovations and start the change - to recycle more and to produce less waste.

Hi Taylor You might want to add the native hoptree (Ptelea trifoliata) and the herb rue to your list for larval plants for the giant swallowtail. Rue fits nicely in the butterfly garden and also is used by black swallowtails. Hoptree can be used outside of the garden since it makes a small tree or large shrub, doing well in a lightly shaded mixed border. Enjoyed the article. Donna Native Nurseries

About 15 years ago, I attended a slide-illustrated program at a Garden Club meeting. The Florida DOT's District 1 staff person for road-side wildflowers was the presentor. The Wildseed Co. of Fredericksburg, TX was recommended as source for our home landscapes. I have been planting this company's Southeastern US mix..and cosmos specialty seeds...ever since. I love to give small bouquets. I love to look at my beds in front and read of my home. In addition,my photo of coreopsis in a roadside ditch won "First Place" in photo contest!

Hello Taylor: Thanks for the diagnosis flow charts! I have a fruit and vegetable garden at home in addition to our landscaping, and what would be helpful is a couple of definitions, and some instructions what to do once we've diagnosed the problem. Hopefully at some point someone wrote an article about how best to do that, and perhaps you could add a link. With regard to definitions, what are mobile vs. immobile nutrients? I would think "necrotic" means something similar to yellowed or scorched, but since you used the latter terms in other places in the charts, does it mean something different? What does "chlorotic" mean? Thanks for any additional information you can provide. -- Sharon McAuliffe
