Welcome to my blog about bulb forcing

bulb bowls hyacinth cat

The bulb forcing year starts in August/September buying bulbs. Then the bulbs quietly grow roots in the dark until the beginning of December when they are brought into the light and warmth and can begin blooming from Christmas day onwards when it is magic to have flowers and scent indoors in the middle of winter.

I used to force about 200 hyacinth bulbs each year but it's too many for me to manage so it's more like 100 now. I'm always trying to formulate the best ways to force hyacinths and this is the documentation of my results. I also have a site devoted to hyacinth vases (www.hyacinthvases.org.uk).                       (please note that all text and images are copyright)

turning the hyacinth upside down, this is the view of the bulblets, for them to grow they need some of the basal plate of the bulb still attached so I carefully removed them

It's time to review the remaining hyacinths. Although some of these weren't that developed I decided they could come out of the dark into the light.

These were still in the dark with no significant stems appearing.

I turned the bulbs over to see what was happening with them. Only 1 had any roots and even those were not significant.

I usually use 1 white variety of hyacinth and this year I tried Snow Crystal for the first time (I think it's new).  They are wildly variable. 5 of the 10 bulbs have no roots at all, 5 have roots varying from "some" to "reasonable" to "lots and lots" (according to my notes). One is in bloom. One has more well-developed bulblets than I've ever seen on one bulb.

These two photos are all 10 of my Snow Crystal hyacinths.

Jan Bos is an early one I know but I have not grown Scarlet Pearl before but so far, it's early.

I brought the crocus out of the dark (19-11-2024), both vases and the Wedgwood hedgehog. The stems are quite fat so I assume buds are out of the bulb. I've had hit and miss results with crocus. I'll just have to see how they do. I'll top up the water in the vases. I find crocus bulbs need to touch the water unlike hyacinth bulbs which must not touch the water.

I put some muscari in those small jars with pebbles a few weeks ago. I put them outside this week, not realising we'd have such cold freezing weather. One broke.

first hyacinths out of the dark

First hyacinths out of the dark. The bulge of the flower needs to be out of the bulb. I think these look well on the way. Initially the stems are quite yellow as they've been in the dark but after a few days in the light they will green up. They all seem to have lots of roots.

continuing bulb forcing - crocus and muscari end of Sept

I started the crocus forcing, putting a crocus bulb in each vase, filling them with water, but unlike the hyacinth bulbs which must not sit in water, the crocus doesn't seem to start growing roots unless the water touches the bulb. As with the hyacinth vases, into the dark to be checked in a few weeks.

crocus vases bulbs

I find the muscari will not grow in a vase with water, unlike the hyacinth and crocus. They need to be on something like pebbles or compost. I've been collecting these little jars which I thought would be nice with some small bulbs. I put some pebbles in each and 1, 2 or 3 bulbs in each depending on how many fit, filled with water and into the dark. I can't remember if they like to be in water like crocus or out of water like hyacinths. I think they are touching the water. I'll check them in a few weeks.

I have a Wedgwood hedgehog I put crocus bulbs in.

start of the forcing year 2024

16-9-2024

The first step in forcing hyacinths is buying bulbs. I got my bulb delivery from Peter Nyssen a couple days ago (ordered them in August) but there are bulbs in the garden centre if you didn't order mail order. This is the first time I'm forcing hyacinth bulbs in my new place so it's rather stressful. I no longer have my cellar but I do have a cabinet in my garage although not exactly sure how all the vases will fit in that. I updated my spreadsheet and printed it to note which hyacinth variety I am putting in each vase. I also had to clear off my patio table to work on.

forcing hyacinth bulbs

I mostly buy mail order but I have some very small vases that need smaller bulbs, those 3 on the right (white and 2 clear), for example. I have found Sainsbury's bulbs are quite small and will do a count of how many I need and buy some. Since moving I'm not so close to a Sainsbury's so will need to make a special trip (I used to go all the time but it was only 5 mins away).

I started with Apricot Passion hyacinth bulbs (4 on the left) and Scarlet Pearl on the right. I've not used thoses varieties before. I like to try different hyacinths (both prepared and unprepared) and compare results.

forcing hyacinth bulbs

Whenever I start my hyacinths, at least one cat comes and checks things out. I like to put white hyacinths in the green vases. This year I bought Snow Crystal, a new variety I've not tried before.

forcing hyacinth bulbs

Those tall green vases have very large openings, so had to use Scarlet Pearl rather than Snow Crystal.

forcing hyacinth bulbs

I filled each vase with water ensuring the bulb did not touch the water and put them in the garage. I will check them in a few weeks. When the bulge of the flower is out of the bulb and the stem is bulging, it will be time to bring them out into the light.

In addition to the Apricot Passion, Snow Crystal and Scarlet Pearl hyacinths, I have prepared Delft Blue ("the" forcing variety), prepared Jan Bos and prepared Woodstock.

 

17-9-2024 continuing the forcing, I brought out all the tall hand-blown hyacinth vases - my favourite, I usually use Delft Blue hyacinths in those

I have 3 glassroots (designed by Margaret Howell) hyacinth vases, on the left, the purple one is not marked on the base as the others are but so so similar, I have no doubt they are the same producer

late start to the forcing year 2023

mid-December 2023

I was not able to start my hyacinths as usual this year but finally settled in my new place and opened my hyacinth bulbs and put 20 Delft Blue hyacinth bulbs in hyacinth vases. It's extremely late to do this but thought I'd give it a try.

17-1-2024 the hyacinths did well, considering how late they were started

Dec 2023 The remaining 80 bulbs I was not able to force, I planted out, also quite late for bulb planting but it hasn't been as cold as it might be so maybe they will establish .

Start of the Forcing Year 2023

It's July and time to start thinking about forcing hyacinths for Christmas. I know it's early but it takes some planning.

one of my new vases I'm using this year for the first time

I ordered my bulbs yesterday. Looking back at my results from last year, I used 13 varieties. I'm keeping it simpler this year but buying more of a variety to get a proper range of results. I ordered:

Delft Blue, "the" hyacinth for forcing, generally reliable and good results

Blue Star, last year I had good results so buying more of these

Miss Saigon, I usually use these and get good results

City of Bradford, hasn't been available the last couple of years but seem to be now so ordered some, I really like them

Carnegie, haven't used these for years, not sure why but after indifferent results with Aiolos last year, I thought I'd go back to this for my white variety, I usually use one white hyacinth

Woodstock, didn't use this last year, can't remember why but trying it again, usually small as I recall but often great colour

cobalt blue hyacinth vase

another new vase I'm using this year for the first time

The bulbs won't be delivered until August / September so I have plenty of time to get my vases organised.
