October in the Garden: Add, Multiply & Divide (Conquering not included)

It’s officially Fall in the North State Garden and although in a lot of our region it’s been hard to tell based on the fairly high temperatures over the past few weeks, our gardens know anyway. Nights and mornings are finally cooling – and frost warnings are being issued in the high country. The seasonal temperature notwithstanding, it is the length of daylight that trigger most plant’s seasonal reactions – fall color and seed set are included in those responses. And yet even while many plants look as though they are preparing for decline or dormancy, fall in the garden – and for the gardener – is about multiplication and division. And addition!

Fall is the perfect time for planting new spring and summer blooming bulbs. It’s also perfect for planting trees, shrubs and perennials, which will all benefit from the remainder of fall and all of winter in which to put down roots, while not being asked to put on a lot of foliage, flower or fruit growth until spring. Fall is also the time for making more plants from those you and your fellow gardeners already have. Collect seed to sow now or to sow in the spring. As you look around your garden for seed, look to see if your herbaceaous perennials – those that die back in the fall but regrow from the same plant again next spring – look crowded or even dying out in the center of their clump. These are good signs that these plants might benefit from being divided. In most cases this involves using a good sharp and clean spade to literally cut the plant’s root ball into smaller pieces. You can dig the whole plant up and then divide it, or you can just cut a portion of it right out of the ground. If you dig your original plant up, carefully replant it and water it back in with some root stimulator or compost to give it a boost. You can either plant your new division directly into the ground, or if you want to give it a really good chance of survival (and not forget about it), you can pot the division up into container just a little bigger than it’s root system and water and feed it until you see roots popping out the bottom of the pot letting you know you can safely plant it our into the garden with confidence.

As you get to your fall clean-up and pruning back of things, you can try your hand at rooting some of your cuttings. While you treat hardwood and softwood plants differently, in general you will choose a nice good 4 – 6 inch cutting from your chosen plant, strip all leaves from the bottom 2/3 of the cutting, dip the bottom in rooting hormone and then carefully insert this into a small container of fresh potting soil. Keep watered and protected and wait. You may just have a new plant for very little cost and very little trouble.

This month, lots of workshops, classes and special events are being offered to teach us about these very kinds of gardening techniques and much more.
