The 'Growers Dictionary' evolved because as I was writing these pages, I found that I was using the same terms over and over again.
I also knew that there was a time when I didn't know what they meant:-)
Rather than make every page long by explaining each term in full or skimping on the explanation and leave some people floundering in the dark, I thought I'd make a section where I could explain fully what things mean.
If there are any terms you don't understand or want explaining - please get in touch - you won't be on your own and other people might be wanting to know exactly the same thing.
This is a 'glossary of gardening terminology' but that sounded a bit pompous - so I've called it Growers Dictionary :-)
Some of the terms are simple to explain and so you'll find them listed here - others are a bit more complex, so those have live links to another page.
I hope it's clear - my aim is to help, not confuse you... so let me know.
If your seedlings are dying as they emerge, then your problem is very likely damping off. This page tells you what you can do to combat this problem.
These sad little seedlings have fallen victim to damping off.
Do not throw away old seeds until you have tested them to see if they're fertile.
Seed companies rely on you buying fresh stock year after year - you can use older seeds but first you need to know whether they will germinate.
A simple method for testing seed viability - click here or on the photo for step by step instructions.
Useful when plants have outgrown their spot, but also in the case of eg Rosemary when a plant has got very 'leggy. You divide a plant by teasing apart the roots. Replant straight away, give the planting hole a dressing of fertiliser and water well - firm in with your heel.
The next two links on the Growers Dictionary will take you to detailed information about propation of herbs (any plant) by seed or cuttings.
The idea of this is to encourage the plant to make roots up the stems. What you do is just cover the plant with soil until only its tips are showing. It is useful when shrubby plants have become 'leggy' eg sage, rosemary, lavender for instance that has been neglected.
You 'earth up' at the end of the growing year and by late spring, you should see signs of growth.
At this point, you can either leave things as they are or lift the plant and divide the stems where there are roots and replant where you want.

Simple way to increase your stock - maybe with a view to growing herbs for profit
Either term is used - harden off or hardening off.
It means to acclimatize plants to the outdoors after being grown indoors or under cover in some way, say a cold frame or greenhouse or on your kitchen windowsill.
Some seeds are sown indoors early in the season and then planted out when they are established. Some plants have spent a period of time indoors, perhaps over wintering herbs on your kitchen windowsill or have outgrown their indoor spot.
Whichever way, they will need some time hardening off before being left permanently outdoors.
You 'harden off' by waiting for reasonable weather in the late spring (generally around May) and then putting them outdoors for daylight hours, returning them to under cover or inside overnight. The period of time you would normally do this for would be around two weeks.
At the end of May, or when the risk of frost has passed, you can leave them out all the time and plant them in their destination spots.
A plant that germinates, flowers, seeds and dies in the same year. These plants are normally quick to germinate eg basil.
A plant that germinates in year one, flowers and seeds in year two and then dies. The seeds will take a little longer to germinate and the first year the plants will only grow leaf. eg Parsley. That's the reason why people think parsley is hard to grow.
Plants (and right across nature) are programmed to reproduce themselves - they do that by flowering, pollinating and producing seed and the time they take to do that varies - annual -v- biennial.
We use the leaves of the parsley plant - we're not interested in the flower. If you notice, the first year of growth for parsley, the leaves are quite small - the plant is putting energy into developing a strong root system for its main job of producing flowers and seeds in year two. In the second year of growth, the leaves are much bigger. If you let some plants self seed, then you will get a continuous second year strong growth from your biennial herbs.
A plant that comes up year after year, dying down off season and growing again in season. These plants generally grow bigger and stronger each time and they are perfect for 'dividing' to increase your stock.
Generally a small woody plant, such as rosemary, sage and lavender. They are either evergreen or deciduous (lose their leaves off season) and normally grow year after year.
You can propogate shrubs by cuttings, layering or dividing.
If talk of early, mid, late spring, summer, fall and winter confuse you - then here's some Growers Dictionary guidelines.
