Q. How and when should we prune our lantana and oleanders?
|This is a Lantana I saw pruned by a local company. Leaving this much wood remaining will make it very "twiggy" at the base. You can actually prune it much closer to the ground in this.|
|You can see from this close-up that I took last February that suckering can occur much lower on the stems of Lantana. Don't be afraid to cut it close to the ground. Leave about 1 inch for suckering.|
A. Both of these plants are pruned during the winter months since they both produce flowers on new growth during the summer months.
I would delay pruning them until late winter (late January) unless you don’t mind looking at "dead" space (the space is not occupied by anything). For lantana it normally freezes during winter months and you have a choice whether to leave the dead top of the plant in place or cut it down to the ground, leaving one inch of stems remaining to support the new growth beginning in February.
|You can prune oleander close to the ground, just like Lantana. Cut it back to within 2 to 3 inches of the soil surface. This is the time of year to do it up until about the end of January when it begins to push new growth all by itself.|
Oleander is pruned at the same time of year as lantana because it also blooms on new growth, not older growth. You can chose to remove 1/3 of the plant by cutting these largest stems to the ground for renewed growth at the base or you can cut the entire plant to the ground and let it regrow. Your choice. Either way you will see luxurious growth and lots of flowers next year. Again use a fertilizer that supports flower growth and apply it early in the spring.
|This is an example of a fertilizer that will push leaf and stem growth and dark green color. You would apply this immediately after pruning and water it in. A 10 pound bag sells locally for $7.95|
|This is an example of a fertilizer that it increases the number of flowers and their size. It should be applied about 4 to 6 weeks later. A 10 pound bag also sells for $7.95 .|
