Our mild autumn temperatures have accelerated the growth of fall-planted, over-wintering, cover crops.
Back in October I wrote about planting cereal rye as a cover crop in my garden. Since then the crop has germinated and made excellent progress toward establishing itself.
When rye seed germinates, it emerges out of the soil as a single shoot. As time goes by and temperatures are conducive to plant growth, leaves begin to form on the main shoot.
After a couple of weeks of growth, the plant enters the “tillering” stage of development.
Rye is a bunch grass, a self-descriptive term meaning that the plant grows in tuffs or bunches instead of spreading by over-the-ground stems called rhizomes. To spread and take advantage of growing space, the bunch grasses form extra stems called tillers. Tillers grow from the main stem of the plant.
When you look at a rye plants and see it staring to form dense tuffs, that growth you see is the tillers. Each tiller has the ability to form it own roots. In that way the plant has the ability spread vegetatively, essentially producing baby plants along side the main plant.
Farmers are concerned about encouraging tillering because the more fully-developed tillers the crop has, the greater the yield.
Extra tillering allows the plants to fill in bare areas thereby compensating for thin stands or weak germination.
My rye is is in the early stage of tillering and should be in fine shape going into the winter.
One of our jade plants has started blooming this week. Anyone with a jade plant knows this is fairly uncommon. I have had a few jade plants through the years that produced flowers but not very many. So whenever it happens, I get a little excited about it.
There seems to be no way of predicting when a jade will blossom. Lots of people, horticulturists included, have their theories about it. Some folks on the internet say they have it figured out. If that were the case, we’d be seeing truckloads of jade plants in the stores blooming just in time for Mother’s Day or Valentine’s Day — pick your favorite holiday.
Flower production in plants can be a complex proces. Before a plant can flower, it has to go through several steps before vegetative cells change into reproductive cells, ie. a flower bud.
A basic principle in botany is that a plant, like most other organisms, will not reproduce until they reach maturity. One familiar example of this is an apple tree which might not bloom for six or eight or even ten years.
We forget sometimes, that our houseplants’s ancestors originally grew out in the wild with no help from people, thank you very much. Jade plants belong to the genus of plants called Crassula. Many Crassula species go through an annual a rest period in their native habitat. In their part of the world, the rains stop for a while and the Crassulas go into a rest period. It’s critical for the Crassulas that the humidity falls to an arid, desert-like condition during this time.
Once the dry period is over, the plants resume growing and that completes one lifecycle. So, to induce flowering, it would make sense that we try to reproduce those types of conditions found in the wild.
OK, so here is my theory of the erratic flowering of jade plants. Many gardeners or houseplant fanciers love their plants and don’t want to hurt it, I don’t blame them. So they keep watering and feeding the plant all year ’round which keeps the plant in a continuous growth stage. The jades never get a chance to rest and they never get a chance to complete a full annual life cycle. This either delays maturity or fails to trigger the reproductive response.
Many factors are involved in stimulating plants to flower: fertility, moisture, intensity of sunlight, length of daylight, temperature extremes both warm and/or cold, length of time exposed to temperatures, air movement, insect damage, and others. The timing of all or any one of these factors can determine if and when a plant will bloom. Some easy-blooming plant species will bloom despite not growing in ideal conditions. Others, like jade plants I’m guessing, require a more complex sequence of events in order to produce flowers.
All that being said, I have noticed that jade plants are more likely to bloom is they are slightly pot-bound. So does this mean that the plants have been growing long enough that they’ve reached reproductive maturity? Or does crowding their roots induce flowering? Maybe sometime in the future a budding horticulturist will discover the secrete.
I just finished digging the last of our potatoes last week. They were growing in a well-drained, sandy area so I was able to let them sit there in the ground for quite a while after the vines died down. Since I couldn’t get to them right away, leaving them right where they were was the best option. A few weeks in the ground did them no harm.
I’m always excited at potato harvesting time, it’s like digging for buried treasure. You can’t see what you grew until it gets dug up. The excitement starts when you lift the first cache of potatoes from the soil. It’s pretty neat that the humble potato can give such a thrill. I have to admit though, the excitement begins to wear a little thin when my back starts to ache and there’s still a long row to dig.
These potatoes are particularly treasured, they’re the wonderful ‘German Butterball’ variety. They are absolutely the best potatoes I have ever tasted. The yield is small compared to standard potato varieties but the flavor and texture more than makes up for the smaller harvest.
They are so tasty, that in years past, I’ve had raccoons dig them up and devour them while leaving perfectly fine standard varieties alone. They dug up the Butterballs, ate them until they were all gone but then never came back for the other potatoes.
The flavor is hard to describe but trust me they will delight even those who are ho-hum about potatoes. And the texture — wow! You’ve probably heard that the perfect potato should be crisp on the outside and mealy on the inside. These go way beyond that. They tend to form a delicate outer crispness when baked in wedges. The inside texture is so finely textured, it is almost creamy. What a taste experience!
Because of the comparatively low yield, I would not suggest growing this as your main crop, especially if you are trying to grow potatoes for storage. They do however, make a wonderful addition to the flavor palate of a vegetable garden.
Now you know one of my best kept gardening secretes. If you have a favorite potato variety that you think is better than German Butterball, share it with us in the comment section below.
