🪴 Nutrients

How to fertilize Oncidium 'Lemon Heart'

Nutrient, fertilizer, and repotting needs for Oncidium 'Lemon Heart': repot after 2X growth

Most potting soils come with ample nutrients which plants use to produce new growth.

By the time your plant has depleted the nutrients in its soil it’s likely grown enough to need a larger pot anyway.

To replenish this plant's nutrients, repot your Oncidium 'Lemon Heart' after it doubles in size or once a year—whichever comes first.

About a week into her first bloom, purchased in the fall and began spiking some time in November (IIR). Finally starting to have a detectable fragrance, it smells like vanilla with some light powdery notes. I purchased this from Hausermann, it was just labeled Oncidium Twinkle Fantasy so I don’t have any more specific info on the species/subspecies, but she’s cute. This plant is under grow lights for at least 12 hours and so far has been tolerant of high light. It’s on a heat mat (that barely works) but the temps in this area of my apartment have been pretty low (55-65), and it seems to be tolerating the low temps well (shockingly, my Bellinas also seem to be pretty happy and growing in these temps). #Oncidium #OncidiumOrchid #OncidiumTwinkle #OrchidLovers
