Hold the soil moist however not drenched because the seeds germinate, which takes per week or two.
Because the seedlings pop up, skinny them to 6 inches aside when you’ve used the published technique.

Hardening off is a comparatively easy course of that entails taking the plant in its container and setting it within the space the place you can be rising it completely. Depart it there for an hour after which convey it again inside.
The next day, go away it there for 2 hours. Make it three on the next day, and so forth, till you’ve reached a full week. At that time, your plant ought to be acclimated.
From Cuttings
Watercress sends out little roots anyplace a leaf node touches the bottom, or clear water.
So a stem that has been mendacity towards the earth can have a lot of small white roots when you pull it up and study it.
You may even see these roots when you purchase a bag of watercress on the grocery retailer.
That ought to let you know that this plant is a breeze to propagate by taking cuttings. You may even plant the rooted watercress bunches from the shop if you want!
Use a seed tray for horizontal cuttings or a four-inch pot for vertical ones, fill your chosen container with soilless potting medium, and moisten it properly.
Soilless potting mediums are water-retentive and nutritious with out having any of the potential pathogens that may hurt younger cuttings.
seed-starting combine is an ideal alternative. One thing like Tank’s Professional-Lite Seeding & Potting Combine is right. It’s made with compost, coco coir, and perlite.

Dig a gap the identical measurement because the rising pot and gently take away the plant from its container. Decrease the plant into the outlet you made and agency the soil up round it.
Water properly and add extra soil if it settles an excessive amount of after watering.

It’s tremendous if the water stage drops to the purpose the place the watercress vegetation are close to the water however not in it, however the stage shouldn’t ever fully submerge the vegetation.
In addition they lend themselves properly to rising in rafts, or in nets in ponds with shifting water.
