Trailing petunia 'Ultra Plum'

Try to plant in a location that enjoys full sun and remember to water moderately. Keep in mind when planting that Ultra Plum is thought of as tender, so remember to wait until your soil is warm and the night time temperature is well above freezing before moving outside. Planting Ultra Plum in potting mix and loamy soil with a ph of between 4.5 and 8.0 is ideal for as it does best in moderately acidic soil to weakly alkaline soil.

By our calculations, you should look at sowing Ultra Plum about 77 days before your last frost date.

As Ultra Plum is tender, ensure temperatures are mild enough to plant out - wait until after your last frost date to be on the safe side.
