Daniel Leonard, Horticulture Agent at UF/IFAS Extension Calhoun County, answers commonly asked questions about raised bed gardening. In the video he discusses construction materials, the type of soil to use, fertilization, crop rotation, cover crops, and smaller container gardens.
In my ongoing search for low-maintenance vegetable varieties that perform well in small spaces, like my raised bed garden, I decided to try a newish Eggplant variety called ‘Patio Baby’ this summer. Developed by PanAmerican Seed and winner of the 2014 All-American Selections Vegetable- edible category, I was drawn to ‘Patio Baby’ due to the advertising claims made that it was a true miniature variety, perfect for growing in containers, only reaching 20” or so in height and producing both “early” and abundant fruit. I’ve been very pleased with the performance of this extremely unique variety so far in my informal backyard trial and definitely think it deserves consideration in your garden too!

The first observation when seeing a mature ‘Patio Baby’ is how small the plant is, leaves, flowers, fruit, everything. Compared to a standard ‘Black Beauty’ variety, ‘Patio Baby’ plants measure maybe a third as tall and wide. Where a “normal” eggplant fruit might be slightly larger than a softball and often have spines on their calyxes (the green part that connects the purple fruit to the stems), ‘Patio Baby’ fruit are roughly the size of a large chicken egg and totally spineless! I find this smaller plant and fruit size to have several perks. Vegetable plants that grow 2’ tall and wide are just about perfect for raised bed gardening. If you don’t require a large quantity of eggplant, you won’t have to sacrifice an entire bed’s space to ‘Patio Baby’ like you would with the standard varieties. Also, ‘Patio Baby’ fruit won’t bend or break branches and are held strongly on the plants, with no need for staking, another bonus when space is at a premium. Finally, I find it much easier to harvest, handle and prepare the small, spineless ‘Patio Baby’ fruit in the kitchen. Think of them as a “personal pan” eggplant. As I’m the only one in my house who eats much eggplant, I waste a lot less fruit cooking these little guys!

‘Patio Baby’ Eggplant also lives up to its reputation of being exceedingly easy and quick to grow. I purchased a packet of ‘Patio Baby’ seed from Johnny’s Selected Seeds in June and planted three in a 20” diameter decorative pot next to my raised bed garden during the first week of July, behind summer squash that had recently expired in the heat of late June. After sprouting, the plants grew strongly and, true to form for most Eggplant varieties, were bothered by no serious pest or disease issues other than the normal stinkbugs and occasional caterpillar that plague summer gardens in Florida. Around 8 weeks from sowing seed in the soil, cute, egg-shaped fruit were ready for harvest! Over the next three or four weeks, my single plant produced around 50 of the cute little fruit. More than enough for me and plenty to share, the goal of my gardening endeavors.

If you’ve run out of space in your raised bed garden, just want a single plant for your back porch or simply want to try a novelty vegetable variety, my experience this summer deems ‘Patio Baby’ Eggplant is an excellent option! For an eggplant that is space-efficient, very early and heavy producing, and comes in a more easily harvestable, kitchen-friendly package, try ‘Patio Baby’.

2020 has not been the most pleasant year in many ways. However, one positive experience I’ve had in my raised bed vegetable garden has been the use of a cover crop, Buckwheat (Fagopyrum esculentum)! Use of cover crops, a catch-all term for many species of plants used to “cover” field soil during fallow periods, became popular in agriculture over the last century as a method to protect and build soil in response to the massive wind erosion and cropland degradation event of the 1930s, the Dust Bowl. While wind erosion isn’t a big issue in raised bed gardens, cover crops, like Buckwheat, offer many other services to gardeners:

Now that I’ve convinced you of Buckwheat’s raised bed cover crop merits, let’s talk technical and learn how and when to grow it. Buckwheat seed is easily found and can be bought in nearly any quantity. I bought a one-pound bag online from Johnny’s Selected Seeds for my raised beds, but you can also purchase larger sizes up to 50 lb bags if you have a large area to cover. Buckwheat seed germinates quickly as soon as nights are warmer than 50 degrees F and can be cropped continuously until frost strikes in the fall. A general seeding rate of 2 or 3 lbs/1000 square feet (enough to cover about thirty 4’x8’ raised beds, it goes a long way!) will generate a thick cover. Simply extrapolate this out to 50-80 lbs/acre for larger garden sites. I scattered seeds over the top of my beds at the above rate and covered lightly with garden soil and obtained good results. Unlike other cover crops (I’m looking at you Crimson Clover) Buckwheat is very tolerant of imperfect planting depths. If you plant a little deep, it will generally still come up. A bonus, no additional fertilizer is required to grow a Buckwheat cover in the garden, the leftover nutrients from the previous vegetable crop will normally be sufficient!

Past the usual cover crop benefits, the thing that makes Buckwheat stand out among its peers as a garden cover is its extremely rapid growth and short life span. From seed sowing to termination, a Buckwheat cover is only in the garden for 4-8 weeks, depending on what you want to use it for. After four weeks, you’ll have a quick, thick cover and subsequent mulch once terminated. After eight weeks or so, you’ll realize the plant’s full flowering and beneficial/pollinator insect attracting potential. This lends great flexibility as to when it can be planted. Have your winter greens quit on you but you’re not quite ready to set out tomatoes? Plant a quick Buckwheat cover! Yellow squash wilting in the heat of summer but it’s not quite time yet for the fall garden? Plant a Buckwheat cover and tend it the rest of the summer! Followed spacing guidelines and only planted three Eggplant transplants in a 4’x8’ raised bed and have lots of open space for weeds to grow until the Eggplant fills in? Plant a Buckwheat cover and terminate before it begins to compete with the Eggplant!
If a soil building, weed suppressing, beneficial insect attracting, gorgeous cover crop for those fallow garden spots sounds like something you might like, plant a little Buckwheat!

A common question for gardeners at the end of the season is if one should till the soil or use no till practices. Opinions vary regarding this question, even among Extension Agents. However old crops harbor insects, both good and bad. This phenomenon was noticed on some recently cut back tomato plants. The intention was to cut the leftover spring garden tomatoes back to encourage fall production. Instead, a host plant for mealybugs was provided.

Mealybugs are soft-bodied insects that possess a covering of flocculent, white, waxy filaments. They are about 1/8 inch in length and usually pinkish or yellowish in color. Mealybugs have piercing-sucking mouthparts which they use to siphon fluids from the leaves, stems, and sometimes roots of many ornamental and vegetable plants. Mealybug damage produces discolored, wilted, and deformed leaves.
One very common example of an insect pest likely to claim residence in your garden’s crop residue, are squash bugs. They like to overwinter on squash, cucumber, and other cucurbit crop residue. If you choose to not till your garden and leave a portion of last seasons crop in your garden, then you should consider applying an insecticide to your spent crop at the end of the season. A product containing a pyrethrin or pyrethroid as an active ingredient would be a good broad spectrum insecticide to control any pest that may reside on plant residue. More information on pyrethrins and pyrehtroids can be found at the EPA webpage: Pyrethrins and Pyrethroids. If you choose to apply an insecticide, it is important that you follow the information on the label regarding pollinator protection. Another option is to plant a trap crop on the edge of your garden to help attract pest insects away from your desired crops. More information on trap crops can be found in the EDIS Publication: Intercropping, Pest Management and Crop Diversity.

So the answer to the till or no till question is…it depends. It is really up to the gardener. Yes, the residue from crops will add nutrients and organic matter to your soil, but it could also increase pest pressure in your garden. If you don’t plan to remove crop residue and don’t plan to till, then keep an eye out for what could be hiding in your garden.
I enjoy starting my garden from seeds. Ordering seed opens so many more options relative to the limited old-fashioned seed and transplant selections that line garden shelves. Picking newer, improved varieties has several other advantages as well, including increased disease resistance, earlier fruiting, unusually colored/shaped fruit, and generally more vigorous plants. One of the most exciting days of the year in my house is when the cardboard box full of the season’s seed packets comes in the mail! However, I garden exclusively in small, 4’x8’ raised beds and only need a couple of plants of each veggie variety to fill the fridge with fruit; meaning I always have leftover seeds in the packets! In the past, I’ve thrown the excess seed away and chalked it up to the cost of gardening in small spaces, but this spring, as seeds became somewhat hard to come by and several of the varieties I normally grow were out of stock, I started saving and storing my leftover seed packets for future seasons to ensure I have what I want! You can save and store seeds too, here’s how.

Properly storing your leftover seeds is a relatively simple process. While seed longevity definitely varies somewhat according to species, regardless of how they are treated by you, remembering the following few tips can help improve the stored seeds’ viability and vigor for the next season.
By following these few simple tips, you can waste a lot less seed and ensure that you have what you want to plant for the following year! As always, if you have any questions about saving and storing seed or any other agriculture or horticultural topic, please contact us at the UF/IFAS Calhoun County Extension Office. Happy Gardening!
