Garden Tip: Jalapeño

This Mexican pepper, Jalapeno, ranges in the medium-hot level, about 5,000 Scoville units.  This seems pretty tame when compared to the #1 hottest in the world- The Carolina Reaper at 2,200,000 SHU and former world champ- The Ghost Pepper at 1,041,427 SHU.

Growing Tip:

  • Give the plants plenty of space to grow. This is the reason why the seed pod kits come with a certain amount of pre-seeded grow pods and plant spacers depending on the size of your AeroGarden.
  • Feed it extra nutrient upon the 3rd feeding and moving forward. For 3 and 6-Pod gardens, give an extra 1/2 capful. For 7 and 9-Pod gardens, give an extra 1 capful.
  • Schedule grow light to be on during the day. This decreases stress on the plant.
  • Pollinate often.
  • Harvest when the peppers are large and firm. Cut from the plant when they are green or red. The longer the pepper is on the plant, the redder and hotter it gets.




1. Adding Water

  • Add water to “Fill To Here” indicator located under the Water Port flap.
  • Use room temperature tap water or bottled distilled water. Do not use well water which may interfere with our nutrients, or softened water, as it contains levels of sodium usually harmful to plants.
  • The ‘Add Water’ reminder alert will appear on the control panel when the water level is low. For best results, keep the water level topped up to the fill line at all times.

Question: What’s the best way to prune and harvest an herb garden?

Luke C., Niwot, CO

Answer: Great question.  With proper pruning/harvesting you can increase the yield, health and appearance of your herb garden.  They say a picture is worth a 1000 words, so I created a video to help you out. You can watch it here.

If you’re not a video person, the tips are summarized here:

  1. Prune early and often, especially fast growing Basil.
  2. Keep your lights as low as possible as long as possible.  This means prune your fast growing tall plants to keep your lights within 4 inches of your smallest plant.
  3. Prune horizontal growth so that it does not block light to neighboring plants.  See the diagram below.
  4. Always prune at a leaf joint, a leaf joint is the point of connection of a leaf with the stem from which a bud arises.  See the diagram below.
  5. Never prune more than a 1/3 of the plant at one time.
  6. Pruning the newest growth of Basil plants will create more leaf growth and less stem growth.
  7. To keep your Thyme and Mint plants bushy, remove the pieces that have long stems and few leaves.
  8. Rotate the pods and put the fullest side of the plants out and the thinner side in towards the center of the garden.
  9. Basil, Mint and Dill are fast growing plants and require more pruning than Thyme, Oregano, Parsley and Chives which are slower growing.
