Geislar Garden Notes - where the Sieg meets the Rhine

Hello everybody!

I decided to keep notes and records on my gardening endevours in this space and would like to invite you to have a look and share your thoughts. Maybe this thread will be of use to someone growing the seeds that grew in this garden or maybe someone will be happy to see plants from his seeds growing here. Otherwise I’m happy to share the fun of gardening and breeding with you. I like visiting other peoples gardens and hearing their stories and I like to watch plants grow.

I will add some pictures later on, but let me first introduce to you the general situation.

The garden is located in the Rhine valley, in the city of Bonn, at the edge of a village called Geislar. (50° 44′ N, 53 m of elevation)

The piece of land is about 1900 m² big and is mostly an orchard with heavy clay soil, where I have set up a few permanent, semi raised, beds, that I’m enlarging this year.

We rent the property since the spring of 2020, so it’s my 6th season of playing with plants here.

We don’t have running water or electricity on the property.
I collect rainwater from the roof of the shed and work the garden with a hoe and broadfork.

In terms of fertility I did use some pelleted cow manure, horn meal and composted horse manure, as well as some ground rock dust last year. Apart from that I have a compost pile that was colonized with a worm population from my home worm farm. The pile gets fed the excess kitchen waste in addition to the garden waste. Compost from the pile, wormcastings from the home worm farm and some compost tea from a friend go onto the beds, mostly in with the seeds.

Last year I decided to stop using slug bait. Since we rent the place no other chemicals were ever used.

The land likes to grow plums and walnuts. We have blackthorn spreading on one side and maple in the back. And of course blackberries throughout. In the back of the garden there was a big oak tree, but it is pretty much dead now. I’m affraid I have killed it with the labyrinth that I have build around it one year. Since there is more light in the back now, I have set up a new, semi shaded, experimantal bed there.

My current focus is on broad beans and popcorn. I’ve had a good year of tomatoes, a good year of beans. I grew physalis, chillies, pumpkins, peas. With each year it get’s more difficult to remember all the past garden action hence this thread :slight_smile:

So far this season I have planted broad beans (already up!) and peas. Last two years were wet, this year it didn’t rain properly since mid February.

Broad beans - Favas.

Last year I grew the following stock along with a few of my own mixed seed from previous years:
















I kept the seed from the best plants, about 2 kg. This is what I have planted this year along with a few mixed seeds from the Serendipity Seedswap and a crimson flowered variety that I bought from Meraki Seeds.

Planting 15.3.2025. Protective measures. I have lost a lot of seed in the last two years from the earliest plantings from wildlife predation (birds?). No losses this time :slight_smile:

I can send you a monster fava grex end of this season. Thinking it’s way too late for planting now.

Thanks for the offer. Last year I have seen people here growing late season favas. Granted it was a very wet and cool summer.

Mine are the opposite, very early. They must be as I grow in Luleå Sweden, no time for primadonnas!

Wow! That looks fantastic! I’m definitely interested in your northern super early seeds :slight_smile:

By late season I mean that they put them in the ground when mine were already harvested. I think they were flowering in September.

Ok! These don’t particularly like heat. In Southern Hungary, near the Croatian border, my friend got best results with sowing my stuff in November/December. It would overwinter ss 10cm tall little plants and take off like a spaceship in March. Matures before the heat kicks in in late May, early June. January sow didn’t fare as well for him. Hungary is getting too hot for favas. Only works as a winter crop it looks like.

Good info. I have tried a November sowing in 2023, but the slugs finished the small plants off in the course of the winter. I would like to try again with your stock. Overwintering favas would be perfect.

Please, remind me sometime after this season!

Garden update time!

Last Saturday, the 19th of April, I planted popcorn maize:





The soil was easy to work after a shower. The planting is maybe a little early, but I had time and it was a pleasure to work in the garden as the weather and spring atmosphere are just beautiful.

Today and tomorrow we have rain, so everything gets the very much needed watering. Temperatures are 10 °C on the rainy days, minimum is 6 °C on clear nights and on sunny days we get 20 °C. In fact on Monday it was properly hot to work in the sun.

I have planted half of the space with the pictured bought popcorn varieties. The other half got the seed from last years crop. Pink, purple and white Caritas, blue Caritas from the late mother plant with air roots and a little red and yellow Amarillo Rojo. I plan to detassle the plants from last years seed since I had flour corn growing next to them and don’t want to propagate any flour corn contamination lest the popcorn doesn’t pop.

Here are the spectacular air roots:

The favas beans look like this:




The new garden bed in the back looks really nice I think. Especially the peas look happier than in the old beds. In the middle two rows I planted potatoes and in the far row Mangold = silverbeet.





The other peas look a little thin. Next time I’m in the garden I will give them support twigs.



This is what was planted on the 22nd of March here:







In the back I planted the following mix:
