Why am I growing tree seeds?

Anna Noali watering tree seedlings in Burkina FasoThe question isn't one of despair (!) or philosophical musing, but one that seems to be more relevant as the seedlings get bigger. Having salvaged one of the seedlings that had been looking a bit off, with plans to try a repot on the other two, and with all of the plants still growing and in need of another repotting next week I figured it's about time I thought about why I'm growing and looking after the Baobabs and Neems.

Now it's been good to do some research and remind myself of words like cotyledon, and the novelty and entertainment value has been pretty good too; certainly if you're someone who enjoys seeing things grow. Novelty and entertainment on the other hand are most likely not the most important consideration of people living in rural, drylands Africa who use these trees and their products in every day life. People like Anna Noali, from Nagre in Burkina Faso, will be growing and caring for large batches of seelings. They will plant them around their villages and farm lands so that they and their children can develop long term sources of food, fuel, medicine and shelter as well as looking after their soils and land.

I, of course, have none of this sense of urgency. I suppose that in the same way as growing carrots in your garden or allotment, growing the tree Neems and Baobabs from seed has given me a better and more tangible understanding of what it might be like to take such practical steps to providing for your future. And more practical steps are urgently needed next week - namely sand, compost and another round of improvised pots!

Seeds in soil

This afternoon I have been planting tree seeds! As I mentioned, the seeds are very hard and woody, so their dormancy had to be broken. This can be done by soaking in hot water, nicking the seed coating, or using acid (to mimic a passage through an animal's intestinal tract). With acid seeming a bit much, and the ready availability of a kettle on hand, I went for the soaking option. I've soaked three batches of the seeds for three different lengths of time; one that I put to soak yesterday, one this morning, and one just before sowing, so about 24 hours, 5 hours, and 15 minutes. I marked each batch, and I've marked up each pot, so I'll be able to see which are more successful.

I commandeered the kitchen floor, put a layer of old paper down, and got on with the business of sowing seeds. First things first was to mix my soil and sharp sand to make sure that the seeds are in a soil that drains well. I decided to use small pots, rather than a seeds tray, as these are dryland plants and so might need more space for roots to grow down, rather than across. I've put 5 seeds in per pot, covered them over, and given them a soak. I've also borrowed a propagator, so they are now settled in that on one of our sunny windowsills, and hopefully will get enough warmth with the wonderful rise in temperatures we've seen in the past couple of weeks.

I'm feeling a little bit apprehensive now, mixed with excitement. I really hope to get at least a few of each, Baobab and Neem, germinated, and will be so disappointed if nothing happens! I've sown thirty seeds in total, fifteen of each, so it's fingers crossed for the next few weeks!
