Can they all be grow in the same grow bag with grow pots please
Hi, My personal preference is to grow things in individual large pots, eg 12-18" diameter, but don't see why you could not grow all three in the same bag. What you might find worth while is to use two grow bags, one on top of the other with the plastic cut away so it doubles the depth which will give more room for the roots and water. Have tried Aubergines in the past but the summer not long and hot enough for them even in the greenhouse so the fruits never really matured, but worth a try, you never know it might be a hot one !
Brilliant thank you. Will put the three together and hope to get Aubergines. I'd see a youtube video months back and he was down South and had loads of outdoor Aubergines so thought it worth a try.
Keep a close eye on them because I've found Aubergine plants to be Whitefly magnets, so much that I don't bother with them any more.
I've a load of Marigold Plants, Will that stop Whitefly?
I'd not put three plants in one grow bag, grow bags get cheaper all the time, along with the size and contents getting smaller. Large pots filled with decent MPC is the way I would do it, and a different pot for each plant. Just get the feeling the cucumber would rip out all the nutrients, if growing well, to the detriment of the other two.
I did have the Cucumber in a 13 ltr pot but was told it wasn't any good so put in grow bag. I like the grow pots and thats why I've not bothered with huge pots. It's my first time growing so all new to me.
Got to admit I've not tried those kind of pots, for me its the mixing of plants in one bag that I dont really like the idea of, one is bound to be dominant and grab all the root space and nutrient. Been looking to try and work out how big a 13 ltr pot is, I dont do metric pot sizes, it looks big enough to me to grow a cue in, if well fed and watered, but slightly bigger would be better. I cant see how a 13 litre pot would not be big enough but one third of a grow bag would be
Hi, When you say Grow Pots, do you mean this type, that you push into the top of the grow bag ? Here is a list to give an idea of pot size to ltrs, your 13ltr pot is about 10" diameter and agree that its way too small for a toms/cuc/aub, unless you are watering every hour ! I typically use something at least as large as a 40cm pot/tub Standard grow bags seem to have around 30 ltr of compost, but there are some larger types around 40+ ltr, but when divided by three plants its only about as big as your 13 ltr pot. Thats why double decking two standard bags gives you more growing area. The advantage of a 40cm tub for each plant gets 3 times the space and can be individually watered and fed, you can still use you grow pots on the tubs. If you have now got things in your grow pots on a grow bag I would say let them be, they will still give decent results, just that you might not get such a big or long lasting crop. Everyone tries various way and ends up with the methods that suits there conditions, so just let them do their thing this year and enjoy the fresh toms etc.
Ooo, That sounds fab on the tubs. How would I put those grow pots on the tub. You mean filling the tub up the putting the plant through the grow pot? Sorry all new to me and yeah that are the grow pots in the image you provided. Would a 40cm be ok for Tomato plants also.
Hi, One of those cheapo Wilco 40cm tubs are what I use, or anything bigger thats a good low price. Usually plenty in stock at Wilcos as most folk avoid the standard black tubs in favour of the fancy ones. Part of the idea of the grow pots as that you water via the outer ring, but pour the water/feed into the inner ring where most of the 'feeding' roots grow , so they say. You do not have to use the grow pots but if you have them give them a go, just fill your tub up with compost lightly firm it down and place the grow pot on top so the bottom edge is an inch or so in. Many folk will use the contents of a grow bag to fill the tub, I prefer to use a good compost mixed with a bit , say about 10- 20% of home made garden compost or some of the shop bought farmyard manure, like Grow Sures ( from Wickes etc) Some folk use twine for the toms to grow up but I prefer to use a 6/8ft cane and use either the rubber coated wire or spring clips to secure the plant.
For Aubergines I grew the grafted plants & harvested 4-6 decent size fruit off each plant in a good year with lots of sun - have to say I haven bothered this year as last year was a bit of a disappointment & they are so cheap in the supermarket.. but heres a link anyway :-) Aubergine Grafted Scorpio (3) at Suttons Seeds
Hi Jane0o0 the size of pots depends upon how you grow your plants, if you have a solid floor concrete or paving slab base you may need to go as large as those 40cm pots. however if you have a soil border your 13ltre pots are more than enough. if you have a solid floor hight becomes a problem, the bigger higher the pot the smaller the plant before running out of headroom. If you have a soil border just use your 13cm pots drill plenty of holes in the base sink the pot 1" into the border then the roots can grow down into the border, keep the border well watered and feed into the pots this will give you great crops. Another point to watch out for is when fruits form the spent flower will drop off do not allow spent flowers to lay upon leaves as this will cause mould. See photo's my toms in 12litre pots just sitting on border allowing roots to grow into border. regds Sandy
[/url][/IMG] Wow I'm amazed at those tomatoes. They look fantastic. Unfortunately my greenhouse is on a concrete base. Yesterday I went out at purchased the 40cm ricky101 recommended and took the courgette, pepper, aubergine and repotted into the new tubs. They seem to be doing a lot better as well so thank you all for the advice and help. I've also got my first little tomatoes from one of the Moneymaker and Indigo Cherry plants. I do also have some Cucumbers but the bees don't seem to have been into the greenhouse (only wasps) How do I pollinate the Cucumber flowers. Oh and shall I start giving the toms a feed now and if so how often thank you.
What variety of Cucumber are you growing Jane? Most modern varieties these days are self pollinating 'all female' - nowt to do in other words. Yes start feeding tomatoes now the fruit has set, follow the instructions on whatever you chose, I use Tomorite (actually the much cheaper Wilko's equivalent) - which I water in every week.
