1. At this time of year when the weather is warm early Dutch honeysuckle (Lonicera periclymenum) and Lonicera americana are a magnet for night-flying moths attracted by the spicy scent, so try growing one if you have the space.
2. If seedlings and cuttings are growing away well, put them outside during the day to harden off then bring them in at night if the weather is cold.
3. Iris are in spectacular full flower now, but be sure to keep their rhizomes free from weeds so they get baked by the sun which will aid flowering next year.
