FactorRecommendedAvoid
PotAt least 12 inches wide for one plant, with a drainage hole. A pale glazed pot stays cooler in sun than a small black plastic potDo not use a pot with no hole, or a tiny pot that cooks on the patio
MixFresh potting mix that drainsDo not pack garden soil into a container — it stays wet and smothers roots
Summer waterWater when the top inch of mix is dry. Check daily in a heatwaveDo not let the pot dry until the plant wilts, and do not leave it in a saucer of water
FeedA slow-release flowering feed at potting, then a monthly liquid bloom feedDo not pour on heavy nitrogen — you get leaves instead of spikes

Angelonia handles patio heat, but a container dries faster than a bed, so water is the job. [1] Use a pot at least 12 inches wide for one plant, or 16 to 18 inches for a mixed arrangement. [2] Angelface Blue makes a vertical thriller in that pot. Super White uses the same mix and drain. Sun and the midsummer cut for the genus are on How to Grow Angelonia.

What size pot does angelonia need?

At least 12 inches wide for one plant, with a drainage hole. A mixed pot can be 16 to 18 inches. Small black plastic heats up fast in July.

How to pot and water angelonia

Pot one plant at the same depth it grew in the nursery pot, then water until mix runs from the hole.

  1. Choose a pot with at least one drainage hole. Fill it with potting mix, not garden soil.
  2. Set the top of the root ball even with the mix. Leave a little rim so water does not run off the surface.
  3. Place the pot in full sun. Water when the top inch of mix is dry — often daily in a heatwave.
  4. Feed a liquid bloom fertilizer about once a month through the season. Skip a feed if the plant is wilted; water first, then feed.

Bring the pot in before frost

A freeze kills the top. If you want to keep the plant, move the pot inside before nights drop toward frost. Many gardeners find indoor overwintering hard and simply buy new plants in spring. [3] [4]

  1. Before a cold night, move the pot to a bright, frost- free room. Do not leave it on a freezing porch.
  2. Cut lanky stems back by about a third if the plant will not fit the door.
  3. Keep the mix barely moist. Do not keep it soggy in low winter light, and do not let it dry out completely.
  4. Hold fertilizer until you move the pot back out after frost.

When do I bring the pot inside?

Move it before nights drop toward frost. Waiting for the first freeze is too late. If indoor light is poor, treat the plant as an annual instead.

If lower leaves yellow in a pot, check the drain hole first. Wet mix, not a missed feed, is the usual cause.

FAQ

Can I use garden soil in the pot?

No. Garden soil packs in a container and stays wet. Use a potting mix that drains.
