Kristen suggested Sweetheart melon as a pretty reliable variety for the greenhouse but he doesn't seem to have posted on here lately. :unsure:
Unlike my cucumbers they have really taken off and are now being trained anywhere and everywhere!
Lots of male flowers but also several female ones as well, some on the main stem but mostly on side shoots.
I've done my best with the little paintbrush to pollinate them (seems to be very little pollen in the male flowers though :unsure:) and it's a bit early to say whether they are starting to set or not.
If they do, would you suggest stopping each side shoot after a fruit has set, and how many fruits do you think is a realistic number to aim for (these plants are seriously rampant at the moment!)

Er, anyone apart from me growing any variety of melon indoors then? :unsure:
-
Yes I am for the first time, but I have no idea what I'm doing- I have three in a growbag in my plastic greenhouse. So far not alot is going on - lots of foliage and some tiny embrionic fruit but no flowers open and the embrionic fruit is not doing anything (ie growing...!). Not really sure what I should be doing with the plants - like pinching them out...? Not sure of the variety, will check the seed packet later. So I would be grateful for some advice from any melon experts too! ::)

I have grown Sweetheart every year since i got my allotment (9 or 10 years now) apart from this year as i didn't have the greenhouse set up in time.
I grow Sweetheart as a guarenteed cropper and experiment with others like Ogen or Bastion.
Sweetheart have never failed to give me a good crop of upto 6 melons per plant.
I grow mine in 12inch pots on greenhouse stageing with the pots in a growbag tray, i water from the bottom to stop stem rot, the top of the pot looks dry but an inch bellow the surface is wet, i like to grow melons in pots as i feel i have more control over the moisture and feeding .
I nip out the growing tip when it gets to around 10 to 12inch's and then run the 2 runners up some netting that goes to the eves of the roof.
You get side shoots comming off the 2 main stems and this is where the fruit comes from, when you see a fruit (female flower) hand polinate it and then when it sets (doesn't always work) nip out the side shoot 1 leaf after the fruit.
Now water and feed every 2 to 3 days and stop too much foliar growth from growing.
Do this on all the side shoots until mid August as any fruit set after then won't come to anything and will stop the set fruit from reaching it's full size.
Remove the ripe fruit when it smells sweet and Mellony ;) :lol:
Hope this helps.

Stompy, thats brill! Thanks! :)
Far too late to do the "pinching out at 12 inches" bit but the rest of the advice is very useful.
Still too early to say whether the half-dozen or so female flowers have set yet; did you find that there wasn't much pollen in the male flowers at any stage of their (brief) existence?
-
No there doesn't seem to be that much pollen in them.
I pick a male flower, remove the pettles and use the male part to polinate.
I have used a tiny paint brush before but use this method now for all this type of plant melons and squashes (etc).
People say obout eating the fruit straight off the plant, and that is very nice, but i find it much better after being in the fridge for a couple of hours cold sweet and juicy.
It's one of my favourite things to grow and the satisfaction from growing melons is matched by nothing else in my opinion.
Well maybe grapes, but thats another story ::)

I've got 7 melon plants in the tunnel for the 1st time and they are growing really well but have never seen the female flowers open. :unsure: how can they be pollinated if they never appear to open. The small fruit behind the flower dies off with the flower after a few days which indicates that it's not been pollinated. Getting worried that I'll have lush green plants and no fruit. :(
I didn't pinch out at all - is this another lesson learned? I could post a piccie if that would help to tell if I'm doing it right? :wub:
-
Mine now suddenly have lots of male flowers open - but the female flowers are shut! ::)
-

Not had that problem; they've all been open at the same time, although of course they will eventually all shut up shop and die whether male or female (and whether they've "done their job" or not!)
So far I've got one fruit which is definitely swelling but it's so hairy I'm not sure whether it hasn't got mildew as well! :unsure:
Two plants, one on the floor which has grown well but is only just starting to produce side shoots and hopefully female flowers, the other is on the staging and has produced at least 6 female flowers so far, all of which have had the "paintbrush treatment".
To be continued............................... :)
-

Don't worry JayG, they do start off super hairy but as they grow they seem to lose them.
-
Might have to have a re-think here!
The plant on the staging has just about run the length of the 8' greenhouse and is showing no signs of slowing up.
I have 10 "fruits" on about 7 laterals (so some of the laterals have 2 on - oops!) and they are all from about the lower third of the plant, so at this rate I would have about 20-30 fruits before the end of July if they all set (2 have definitely set so far.) :ohmy:
Even as a beginner I can appreciate that is far too big a load to successfully grow and ripen, so Q for Stompy (or anyone!) please: You say you get up to 6 melons per plant - is that the most they could muster on their own or did you ruthlessly cull anything over that number?
(The other plant on the floor is being much more sensible; it's only just thinking about opening its first female flower!) :)
-
I used to get as you say plenty of baby fruits but only let one grow on each latteral.
The reason for this is that if there are 2 fruits on a latteral the first fruit grows and swells ok but the second doesn't do too well and doesn't ripen, it also affects the overall size of the first fruit.
The plant can only sustain a certain amount of fruits due to it's root size, i grow in pots to get a good plant and good flavour but i would still only grow 1 fruit per latteral still.
I would cut all that leafy growth back to around 4 to 5 leaves after the last/top fruiting latterals so the plant puts more into the fruits.
Also keep hand polinating and i wouldn't allow more than 8 fruits on your plant, i found 6 to be best for me, think about all the water needed to swell them to 5 or 6inch's

Thanks Stompy. :)
Things have changed over the last few days; I did remove the 2nd fruit on the laterals with 2 on (and also a lateral with an egg-sized single fruit by mistake ( :mad:) but despite my best efforts with the paintbrush the "fruits" are aborting at a rate of knots, so I might be lucky to get to six per plant the way things are going. :(
-
You do get that with the fruit not setting, they just turn yellow and drop off :nowink:
Keep hand polinating every time you go and even if you have polinated one do it again with a fresh male flower instead of the paint brush.
and also a lateral with an egg-sized single fruit by mistake
I have done that more than once too :lol: :lol: :lol:

Thought I'd post a pic for those (very few) who seem to be growing these melons because I AM GETTING VERY EXCITED!
If you are wondering how many fruits are visible in the photo the answer is 6 (9 altogether on this plant.)
(If you are also wondering whether 9 is a somewhat reckless number to try and grow to maturity the answer is "very probably!) :wub:
-
I am growing these too but I read somewhere that they can cross pollinate with cucumbers so i moved them out of the greenhouse just in case. I put them against our south facing wall but to be honest they haven't done much at all. Growth is slow and a few flowers but no fruit whatsoever.
I am going to try them again next year but keep them in the greenhouse ::)
JayG your melons look fantastic . I am quite envious :tongue2:

Wow! Very impressive. I'll have to upload a photo of my melons (that's the fruit people!) I'm pretty sure they are watermelons and not galia (which is what they are supposed to be)!

I am growing cantaloupes in the greenhouse. I have three in a raised bed which have suddenly shot across the floor in every direction so much so that I have just trained them up sticks.
So far I have male flowers only. I shall follow the advise in this post as I am new to melon growing.
The business of counting up main stems and shoots etc then cutting back to produce growth looks confusing but I can read a road map I reckon I'll me alright.
The picture of Jay G melons is the 'pattern' I'm working to.

I have one Orange Sherbet and three Sweetheart melon plants in the GH. I trained them to climb but didn't pinch out the tops until they reached the top of the frame. Think I did this too late. However I have hand pollinated, which most didn't set but one has and it's light bulb size. I'm so excited. Reading earlier I will now pinch out one leaf after. Nothing much is happening with the Orange Sherbet. Has anyone grown these?
-
I am growing Ogen, the plant is very healthy and is heading out over the summer room, I feed and water it and the male flowers all seem to apreciate this but I do not have one femail flower, I know it is very late in the season to get any fruit now but if I do happen to get a femail to polinate I will have to just nurse one fruit. :(
-
Well one fruit is better than none. I'm determined to have this melon. A friend of mine told me there's no point growing anything in the North except the staples. I will prove him wrong. x
-
Unlike courgettes the male Sweetheart flowers seem to produce very little pollen, and I then have to beat the hoverflies to it (there are thousands of them this year!)
If you can catch a newly opened male flower and really dig in with an artist's paintbrush (it seems to fall off into the bottom of the flower) you should get a fine yellow dusting of pollen on it which of course you carefully transfer to the middle of a female flower.
Quite painstaking work, and it doesn't always work, but it's worth it to see such exotic and inviting-looking fruits dangling from the plant (especially when you managed to kill off your cucumbers! :)
-
well done with the melons so far Jay. I may have to try them next year now :tongue2:
I just don't know how you've crammed these in, what with the sweet potatoes, some cukes and tomatoes :unsure:
Your greenhouse must be like Tardis :lol:

Pay attention Mum; MY CUCUMBERS HAVE GONE TO CUCURBIT HEAVEN!

........but I do have the others you mention (plus sweet peppers and basil!) :)

oops! sorry :blush:

Mine have got even more foliage on them now plus both male and female flowers - I tried hand pollinating but have no idea if the fruit has set or not... time will tell... ::)

I found a little sweeheart fruit today YAYYYYY!
It's the size of a duck egg :D :D :D

Duck egg is good, and it will soon be an ostrich egg (no idea what happens after that!) :lol:

Eat it, I hope :nowink:
-
Four more flowers today, all male :( :(
-
Mine look as if they will finish up with about 6 melons apiece, as any further female flowers have either failed to set or grew to duck egg size and then aborted.
In other words, that's just as Stompy predicted earlier in this thread, (luckily the plants seem to know much more about their capabilities than I do!) ::)
