The guide here says Jan to March - it is now April. I suggest you plant ASAP.

Check the pages here for broad beans - plant April-May and August - Sept. Potatoes plant Sept to Dec.

Potatoes are normally planted in mid to late spring when the possibility of frost is over.

Buy from a nursery, farm produce agency, seed selling online store. Some hardware/garden store might have them.

Read the notes here the info is all there. One thing they say is to plant Aug/Sept etc, same as where I live in Australia. But here they plant April/May and also in Aug Sept.

I have dense clay yard soil with rocks so I may need to get ALOT of mulch to grow potatoes in zone 9b. Right? I'm a total beginner so any tips or feedback for zone 9b would be appreciated

I like the idea from the gardener in Australia. G'Day to you. I also have soil like you with clay and rock so digging the trench allows a quick easy replacement but drainage can be a problem with the rocky clay soil. Potatoes love water but too much and they will rot. Try choosing a location with a higher elevation if possible. Sometimes rain pooling can be avoided at higher locations by digging a small trench as a drain. Avoid areas that are already wet or are typically wet. At my place the trench filled with water and took more that a week to drain. I back filled the trench and chose another location.

You could try digging a shallow trench, put the seed potatoes in this, and cover with straw/mulch and compost or rotted manure. Keep topping up the straw as the potatoes grow. You'll end up with potatoes and some good quality soil.

The handbook-which I provided the location to in my prior reply is not very beginner'ish but it is comprehensive covering issues you may never encounter- but you do need the reference material. I have a few thoughts to add. 1. Hilling up while the plant is growing-if you are covering leaves I find this fundamentally wrong. Leaves are specialized and designed to collect light, they are not roots. So I opt to plant my seed potatoes deep enough on day one- however I tend to have the luxury of very well airated, light soil. This means the seed potato has a steady air supply and can sense the heat from the sun even at deeper depths 2. Your seedpotatoes need all their potassium Immediately. Potatoes strangely take up all their potassium that they need really early. -and don't uptake more. If there is not enough potassium in the very early stages your potatoes might have hollow heart (looks like hollow rotting middles). Late application of potassium tends to be useless 3. Potatoes seem to respond really well to the addition of microryzal fungi - in my area we source that under pine trees in a forest- we just take some forest floor duff with a dust pan and add to the potatoe planting soil. To sum up - your seed Potatoes should be about the size of chicken eggs (if larger cut up ensuring an eye on each piece and allow a few days to heal/scab up before planting). You need to chit them(make them sprout-place in dark so they sprout). Plant in soil with Compost, a sorce of potassium and microryzal fungi. If for some reason you cannot source any compost/pottasium/microryzal fungi -plant anyhow potatoes are tough -there is still a good chance they will be Okay -depends on the condition of you soil. In my area I can water deeply once per week. Harvest when about half the leaves have fallen over as if to die. If you harvest sooner you may be compromising on size-because as long as those leaves can collect light they can store the energy in the tubers. Good luck - it is so much easier than it sounds- and all those diseases in the handbook are rare and if the plants are strong (well fed) they can manage just fine, potaoes are pretty tough root crop. In other words- you can grow potatoe.
