Indian Bean Tree (Catalpa Bignonioides) | 25+ seeds

• Soak the seeds in water for 24 hours then drain
• You can mix the seeds with a little dry sand to make sowing them much easier.
• Fill container (with drainage holes) with general purpose compost 
• Gently firm the compost 
• Sow the seeds on the surface (light is required for enable germination
• Mist or water carefully to avoid disturbing the seeds
• Cover with clear plastic bag, clingfilm or similar with a couple of air holes
• Keep at room temperature out of direct sun
• As the seedlings begin to germinate, slowly remove/open the bag over a few days
• Pot on seedlings once large enough to handle
• Keep in pots and give winter protection for the first 2 seasons

Olly's General Guide to Seed Sowing!

I love sowing seeds and it runs in the family - dad, granddad and finally my great-granddad for whom the hobby helped him get over his experiences in the Great War. I still get a big kick when I see the first seedling poking through from a new plant that I have never sown before or been successful at. However, even the most experienced gardeners draw "blanks" from time to time. Whilst I sow all the seeds that I sell so I know that they are viable, some are trickier than others and problems can arise so here are some tips to make "blanks" few and far between:

1) Dont Rush! Tempting though it is when that packet arrives in the post to simply bung the seeds in some compost!

2) Google and YouTube are your friends! Take some time so see the methods other people use to germinate the seed. 

3) Think Nature! What conditions do seeds face? For example a seed from a tropical plant will fall to the warm, wet and dark jungle floor. A seed from the mountains of Europe will fall to the floor in Autumn, then have to endure months of freezing temperatures before germinating in the spring. So as growers, what we are trying to do is to simulate the conditions that the seeds will naturally experience and there are plenty of tricks that can be done to short cut the processes somewhat.

4) Good compost pays dividends. The best investment you can make is to purchase three bags - one of potting compost, one of vermiculite and one of horticultural sand. With these three bags I can make up whatever soil type a particular seed likes (although for most seeds I find a 50/50 mix of compost and vermiculite works just fine) 

5) Rot is your enemy. The single biggest danger to seed germination is rot - either before or after "damping off" the seeds germinate. To reduce the risk, ensure you have good free draining soil mix and that it is moist but not wet. Unless the seed variety absolutely requires it I prefer NOT to cover my seeds trays with plastic bags, Whilst germination is often faster this way, it greatly increases the risk of rot. I prefer to place my seed trans inside a watertight plastic tray and water from the bottom - airflow over the surface reduces the risk.
