It bloomed and have begun production is not uncommon with a well-grown of offsets, I impatiently keep an eye This month, I am turning my Galactic Warrior to get another attention to potting-up a gang of out to see how many Neoregelia offsets that have been offsets I’m going to growing in my collection. So I get. And then I keep thought – why not incorporate this watch to monitor the into July’s Blade? This is basic stuff – size of the offsets, cutting off offsets, mixing up potting because once they’re media and planting them. I do not about one-third of pretend to have the best techniques the mature size, it is or recipes, but I’ve had a lot of fun time to with this particularly rewarding propagate. Not to genus of the bromeliad family. Why worry if they stay rewarding? Well, they grow attached and get relatively fast, going through their bigger; you can cut life cycle often in just 2-3 years from them off the small offset, to adulthood, to “mother” plant even blooming and to then producing the when they approach next generation of offsets. More maturity! In these often than not, your Neoregelia, or cases, keep only Neo, will produce several offsets that actively growing can be easily propagated, as I will roots, not the old discuss here. July is a good time to roots from the bounce around some propagation ‘mother’, which topics, as many Neo’s have pups on could rot in the new them large enough to remove now pot.

For longer-living species and hybrids, I plan for permeability of the media over time by using more inorganic material (perlite and lava rock) and chunky organic material that takes longer to break down in the pot. For medium and large growing Neoregelias, I typically use 5” to 8” plastic pots, and I fill the pot to within an inch with Potting Your Neo Offsets lightly packed media, Most Neo’s are not too particular placing the offset in the about their potting media as long as middle of the pot.

She showed us how she uses broms in the landscape, with lots of visuals. Loved to see her eclectic and very personal style of gardening, where bromeliads are front and center. We had a plant table by Dave Kennedy. Auction plants were Neoregelia correia-araujoi (see story on page 4), Tillandsia aeranthos hybrid, Billbergia ‘Raspberry Spritzer’, Neoregelia carolina x concentrica x ‘Charm’.
