Grow Mint Indoors

November 17, 2018

Want to grow mint indoors? If so, you're in luck. Mint is relatively easy to grow in moderate light levels. If your mint gets leggy on your windowsill, that means it needs a grow light. There are hundreds of mint varieties, but popular types include chocolate mint, orange mint, lavender mint, apple mint, and pineapple mint.

Mint grows more vigorously and produces more foliage and essential oils with longer days - but it also flowers more. You can grow under 12 to 13 hours of light from grow lights to slow flowering, or keep flowers pinched and harvest regularly under longer photoperiods of 14 to 16 hours.


Can You Grow Citrus from Seed?

November 16, 2018

You can start citrus from seeds you kept from fruit you purchased. If you start a seed from a hybrid variety of citrus, your seedlings won’t come true to variety.

You can also propagate citrus from cuttings, air-layering, and grafting. Otherwise, pick up young or mature specimens at your local nursery and pot them.

New 2019 David Austin English Roses

November 16, 2018

Each fall, I am excited to receive the latest list of new English rose releases from David Austin roses. I am a HUGE fan of English hybrid roses – their lovely smell, their stacked petals, and their dreamy colors – each one make me so excited for the following spring.

2019’s new releases do not disappoint. A pale yellow, a stunning fuchsia, and lastly a gorgeous apricot named after Dame Judi Dench – yes, please!


Spring 2019: U.S. & Canada Three Beautiful New English Roses

News Brief

In Spring 2019, David Austin Roses introduces three beautiful new English Roses to U.S. and Canadian gardeners: soft yellow ‘Vanessa Bell’, rich apricot ‘Dame Judi Dench’ and fuchsia/cerise ‘James L. Austin’. “All three are top-performing English Roses, each with distinctive fragrance, beauty and appeal,” according to Michael Marriott, technical director and senior rosarian of David Austin Roses Ltd in Albrighton, England.

Austin’s English Roses are known for combining the classic flower forms and perfume of antique roses with the expanded color range, repeat flowering and disease resistance of modern roses. They can be grown in full sun or partial shade.

In ‘Vanessa Bell’ gardeners gain an exceedingly floriferous English Rose that is, unusually, pale yellow and also compact in its growth habit. “Austin’s breeding team considers ‘Vanessa Bell’ one of the most free-flowering varieties it has ever bred,” says Marriott, putting its level of quick-repeat bloom on par with recent Austin introductions, ‘Roald Dahl’ and ‘Olivia Rose Austin’. Robert Calkin, the acclaimed British floral fragrance expert who serves as Austin’s “rose nose," describes its fragrance as, "green tea with aspects of lemon and, at times, honey.”

Also new are English Roses ‘Dame Judi Dench’ and ‘James L. Austin’.

‘Dame Judi Dench’ has large flowers in a glorious, sun-kissed shade of apricot that pales prettily towards the edges, where the ruffled petals catch the light in a halo effect. Its fragrance combines a lovely tea scent with notes of cucumber and a hint of kiwi.

'James L. Austin’ has densely-petalled flowers in an unusual shade of reddish-pink. The large flowers have a fruity fragrance that evokes a mixture of blackcurrant, blackberry, raspberry and cherry, with hints of lemon zest and almond.

Use Grow Lights to Grow Citrus Fruit Indoors

November 15, 2018

Grow citrus indoors with 12 to 16 hours of supplemental light. You can get good growth and vigor from citrus using MH/CMH, CFL, or intense HO T5 lamps, but you’ll need a full-size grow lamp.

You can also place citrus plants inside grow tents with HID lamps for best production. If you have very bright south-facing windows, you may be able to combine that natural light with a few spotlight CFLs to keep a group of citrus happy in your living room.

Grow Light Shelf Setup

November 13, 2018

Your setup will depend on your level of interest and commitment, space, and budget. You might use a combination of equipment and setups. Shelving, closets, and countertops all hold plants in my house.

Young seedlings, houseplant cuttings, African violets, medium-temperature orchids, and cooler-season vegetable crops occupy indoor areas at any given time year-round. I also have a couple of previously unused indoor closets that work nicely for tucking away crops that like a bright spot in the 65°F to 85ºF (18–29°C) range without exposure to very hot or cold temperatures.

How Does Photosynthesis Work?

November 12, 2018

If you're interested in gardening under lights indoors, it's good to have a basic understanding of photosynthesis. Photosynthesis is a reaction to a transfer of energy. Think of a plant’s leaves and green stems as light-energy collectors; nature's very own solar panels.

This philodendron leaf turns light into plant energy.
PC: Leslie F. Halleck

Light hits the surface of a leaf or a green stem, and specific cells convert the light energy into sugars. These sugars move around the plant, driving various biological functions. A major by-product of photosynthesis is oxygen; hence, we breathe. When using indoor grow lights, your goal should be to provide enough light to fuel successful photosynthesis.

Hot Temperatures Can Hinder Plant Growth

November 11, 2018

Depending on the crop you’re growing, temperatures that are too hot or too cold can hinder growth and development. Every type of plant has an optimal temperature range for producing healthy foliage and flowers. Temperature settings that are too high, coupled with no water, is a bad combination.

Oops. Even professionals forget to water. This dendrobium orchid got too warm and too dry.

Temperatures for this orchid were too hot and it dried out and dropped all its leaves. Most of the canes have also died. Whoops!

Lamp Wattage and Distance Grow Lights

November 10, 2018

The wattage of your lamp dictates the distance from plants. Lamps that are 150W are not very hot and can be placed within 6-8" of your plants, while 600W lamps need to be kept at a distance of 18-24".

PC: Leslie F. Halleck

My young naranjilla (Solanum quitoense) transplants, and Brugmansia cuttings, are growing about 6-8” below a 4-lamp T5 fluorescent fixture. As they get taller, they’ll need to be moved further away from the lamps or their foliage will burn.
