  • Growing Cactus?

    Hi I have planted several Echinopsis peruviana (Peruvian torch), and Echinopsis Pachanoi (San Pedro) cactus plants. In total I have about 24 plants. I used about 6 seeds per pot.

    I read various advice on-line and in the end settled on a quite rough soil mix of one part sand one part perlite and two parts general purpose compost.

    I added some liquid plant food to about two liters of water in a misting spray, watered well and then bagged them up.

    I also threw together my own window ledge propagator, stuck in a strong light-source on a timer in it and threw in a 300W aquarium heater. (Since I reasoned that this would be ideal for after the germination stage to withstand an early morning misting from an automatic/ultra sonic misting machine I bought off eBay too).

    Two weeks later all 24 pots have now germinated. This was quite a surprise, as previously I have never grown anything. I genuinely didn't expect it to work.

    My question then is simply what do I do now? I have no experience at all in growing plants, let alone cactus.

    They have been bagged for about 4 weeks in total now - and all in all not a lot seems to be happening. (Which is to be expected I suppose). I have no idea if I even got the soil mix right, as most of it was just pure guess work.

    Now that they are bagged, how long should I leave them like this and how often should I water them? Also should I feed them each time I water them too? Also should I bag them up again after I water them next? (Bagging them seems to do a fairly good job of retaining the moisture as the humidity inside the bags seems to be reasonably good).

    I have attached an image of my setup below.

    Of course the difficulty is that I may have to wait a few years to be absolutely certain of what I have, but my main concern is how do I make sure I give my plants the best chance of making it through this initial stage?

    As I said I am a total novice at this, so any help or advice would be appreciated.

    Hi Jebus,

    Well done, they're fun aren't they. You don't need to sow them in separate pots just for info. I sow mine in 2" square pots of compost (similar to yours) water them once and then stick them on the bench with a bit of bottom heat in the self seal bags (the zip type) then they stay like that for 12 months. As you've got a light they will keep growing through the winter so they'll be OK then once the pot gets full I either prick (parden the pun) them out in to seed trays or 40 cell plug trays of a similar compost. They won't need feeding for 12 months as there will be more than enough nutrients in the compost for them - they do grow in deserts! so feeding them is liable to do more harm than good.

    If you fancy trying some more go for the easier ones like the Rebutia's, Mammilaria,s or Gymnocalyciums - they have the benefit that they will flower at a fairly small size.

    Hope that helps, but be warned. I started off with 2 cacti and now have 500!!
