Red Yucca: Neither Red, Nor a Yucca

Image
When I first discovered seed collecting, one of the very first seeds I tried to harvest was that of the Red Yucca. I was attracted to the ease with which they could be identified and plucked from their flower spikes. The sheer number of seeds that can be found in just one pod is quite rewarding.  After doing a quick internet search on how to sow the seeds, I settled on the technique of

How to Propagate Ivy

I recently had someone ask me how to propagate Ivy (of the Hedera genus). Now, I do run a business where plant propagation is about 4/5ths of the job, but am I going to gatekeep? HECK NO!  So let me tell you how to propagate Ivy! Propagation of ivy (as well as many other plants) is more successful during their time of active growth. Spring is a great time to take cuttings!

How to Grow Pride of Barbados from Seeds

Store your seeds in a cool, dark place until you are ready to germinate them. There's a little trick to getting these seeds to sprout quickly. The technique involves soaking the seeds for at least 48 hours in water. I’ve personally had success with adding water at tea-steeping range (195° F). I’ve known other gardeners to pour in fully boiled water (212° F). It is also perfectly fine to plant the seeds directly in soil without following the numbered steps below. Sprouting may take longer, but they will germinate once the soil temperature regularly reaches 75-80° F. 1. Add your seeds to a heat-safe container such as a glass jar, coffee mug or thermos.  2. Fill your container with the heated water.  3. After 24 hours, pour off the water and refill with fresh, heated water for the second 24-hour period of soaking. The seeds are ready when they have approximately doubled in size and the seed walls are no longer rock hard. A second soaking is not necessary if the seeds have alrea...
